Description

Forming method of stuffed food

The present invention relates to a method and a device for forming a stuffed food (such as barbecue) by wrapping an inner material with a raw food dough block.

Patent document 1 discloses a forming device for shaomai (stuffed food), and the relevant forming device includes: an extrusion device for extruding an inner material, and a turntable arranged below the extrusion device, the turntable having a bag body for accommodating the inner material. The shaomai skin of the outer skin material is placed on the bag body, and the tube of the extrusion device is inserted into the bag body to form a cup shape. In addition, the inner material is extruded from the tube and filled into the inner side of the cup-shaped outer skin material to form a stuffed food with a head of the inner material exposed. Afterwards, the formed stuffed food is taken out from the turntable.

This forming device can only form the stuffed food into a cylindrical shape. In addition, the peripheral portion of the shao mai wrapper protrudes upwards more than the inner material, so the peripheral portion is manually bent toward the inner material to be closely attached to the inner material (see patent document 1).

In addition, Patent Document 2 discloses a forming device for filling food such as shaomai or steamed buns, and the forming device includes: a plurality of skin-gathering members that capture the shaomai skin that supplies the inner material from the side and freely open and close to form the filling food with the head of the inner material exposed, and a plurality of shaping members that freely open and close to align the upper part of the shaomai skin of the filling food. This forming device is constructed by linking the opening and closing actions of the skin-gathering members and the shaping members through a connecting rod mechanism.

Furthermore, Patent Document 3 discloses a forming device for a filling food such as a Chinese stuffing bun, wherein the forming device includes: an adjusting device for gathering the peripheral portion of a flat outer skin material with an inner material disposed thereon above the inner material to form a sealing protrusion into the filling food, and an outward extension prevention device for preventing the outer skin material of the filling food disposed below the adjusting device from extending outward. The adjusting device includes a plurality of freely openable and closable adjusting pieces, and the outward extension prevention device includes a plurality of freely openable and closable outward extension prevention adjusting pieces.

The regulating device gathers and seals the peripheral portion of the outer skin material in a manner of covering the inner material, thereby forming the head of the stuffed food. The outward extension prevention device sets the front end of the outward extension prevention regulating piece to a predetermined width when the inner material is supplied to the outer skin material, and blocks the raw dough block of the food so that the outer skin material forming the body of the stuffed food does not extend outward (Patent Document 3).

In addition, Patent Document 4 discloses a forming device for forming a filling food such as red bean paste bread, and the relevant forming device includes an adjusting device for sealing the periphery of a flat outer skin material with an inner material. The adjusting device includes a plurality of adjusting pieces that can be opened and closed freely. The side surface of the adjusting piece has: a front edge portion that is first sealed during the closing action of the adjusting device, and a rear edge portion that is closed later than the front edge portion.

The regulating device gathers the peripheral part of the raw dough block of food and seals (closes) it during its closing action so that the rear edge of the regulating sheet covers the inner material respectively. The forming device forms the head of the stuffed food so that the raw dough block of food is not exposed above the regulating sheet, so that the outer skin material is wrapped in the inner material to form a shape.

[The problem that the invention wants to solve]

The forming devices described in Patent Documents 1 and 2 form stuffed foods of a single size. When the size of the stuffed foods is changed, the components of the respective parts must be replaced, and therefore the forming devices are not versatile.

The forming device described in Patent Document 2 is provided with a shaping member for aligning the upper portion of a raw food dough block for filling food, but the shaping member cannot bring the raw food dough block into sufficient close contact with the inner material, and thus cannot perform stable forming.

The forming device described in Patent Document 3 must have two devices, namely, an adjusting device for forming the head of the stuffed food and a device for preventing the body of the stuffed food from protruding outward, so its structure is complicated.

Although the forming device described in Patent Document 4 is provided with an adjusting device for forming the head of the stuffed food, the adjusting device is not connected to the body of the stuffed food.

The present invention aims to solve the above-mentioned problem and to provide a method for forming a stuffed food and a forming device thereof that can surely push a raw dough block of food toward an inner material. [Means for solving the problem]

The present invention is a method for forming stuffed food, comprising: a step of passing the central portion of a thin sheet-like outer skin material provided with an inner material through an opening of a loading member and vertically raising the peripheral portion of the outer skin material from the loading member, and a step of closing a regulator including a plurality of regulating pieces, thereby pressing the peripheral portion of the outer skin material vertically raised from the loading member toward the inner material with the inner side surface of each regulating piece.

For example, in the above-mentioned pushing step, the inner side surface of the above-mentioned adjusting piece includes: a first inner side surface extending upward from the bottom surface of the above-mentioned adjusting piece and a second inner side surface formed above the above-mentioned first inner side surface and inclined more inwardly than the above-mentioned first inner side surface, so that the above-mentioned first inner side surface pushes the body portion of the above-mentioned stuffed food, and the above-mentioned second inner side surface pushes the shoulder portion of the above-mentioned stuffed food.

For example, the regulator is closed on the upper side of the regulator to close the through hole formed around the regulating piece, so that the head of the stuffed food protrudes upwards further than the upper side of the regulating piece.

For example, in the above-mentioned transfer step, the central portion of the above-mentioned outer skin material is supported by a supporting device arranged below the above-mentioned placing member.

For example, the central portion of the outer skin material is formed to be thicker than portions other than the central portion.

For example, a forming device for stuffed food comprises: a loading member having an opening in the center and for loading a thin sheet-like outer skin material with an inner material arranged thereon; a regulator including a plurality of adjusting pieces; and a driving device for causing the above-mentioned regulator to open and close, wherein each adjusting piece includes an inner side surface for pressing the peripheral portion of the above-mentioned outer skin material standing upright upward from the above-mentioned loading member toward the above-mentioned inner material.

For example, the inner side surface of the adjusting piece includes a first inner side surface extending upward from the bottom surface of the adjusting piece and a second inner side surface formed upward from the first inner side surface and inclined inwardly, and when the driving device performs the closing action of the adjuster, the first inner side surface pushes the body of the stuffed food, and the second inner side surface pushes the shoulder of the stuffed food.

For example, the driving device is configured to perform the closing action of the regulator in a manner that the through hole formed on the upper surface of the regulator surrounded by the regulating piece is not closed.

For example, a supporting device for supporting the central portion of the stuffed food so as to be movable up and down is provided below the placing member.

For example, there is further provided an outer skin material molding device for molding the outer skin material, the outer skin material molding device comprising: a horizontal mold surrounding the outer skin material before molding; an upper mold having a recess formed in the center of the lower portion and pushing the outer skin material before molding from above; and a driving device for the upper mold configured so that the horizontal mold surrounds the outer skin material before molding and then drives the upper mold to push the outer skin material before molding from above.

For example, the above-mentioned cross mold includes a plurality of cross mold pieces that are nearly separated from each other. [Effect of the invention]

According to the present invention, when the regulator including a plurality of regulating pieces is closed, the peripheral portion of the outer skin material standing upward from the loading member can be pressed toward the inner material by the inner side surface of each regulating piece. In addition, during this pressing, the outer skin material can be folded into a flat surface and deformed into a wavy shape. Therefore, a stuffed food can be formed in which the outer skin material is closely attached to the inner material.

Referring to Figs. 1 to 12, a forming device 1 for a stuffed food according to the first embodiment of the present invention is described. The forming device 1 is used to wrap an inner material F with an outer skin material D to form a stuffed food P. For example, the outer skin material D is a shaomei skin, and the inner material F is a stuffing. The forming device 1 for forming a shaomei into a stuffed food P is described below. Referring to Figs. 1 and 2, the forming device 1 includes an outer skin material molding device 2, an inner material supply device 3, and a wrapping device 5. In addition, on the upstream side of the forming device 1, there are provided a relative roller-type stretching device 95 for flattening the adjusted raw dough ball DB into the outer skin material D, and an aligning device 97 for aligning the center position of the outer skin material D in the width direction with the outer skin material molding device 2.

Referring to Fig. 3 and Fig. 4, the outer skin material molding device 2 is a device for molding the flattened thin sheet outer skin material D so that the central portion thereof is thicker than other portions. The outer skin material molding device 2 comprises: a belt conveyor (loading device) 81 for loading and transporting the thin sheet outer skin material D; an upper mold 82 that can be raised and lowered; and a horizontal mold 87 that can be raised and lowered, and the horizontal mold 87 has horizontal mold pieces 88, 88 that are close to and separated from each other.

The upper mold 82 is in the shape of a disk, and has a bottom surface and a circular recess 83 disposed in the center thereof. The diameter of the upper mold 82 is, for example, 100 mm. The depth of the recess 83 is preferably 1 to 2 mm in the case of, for example, roasting. The diameter of the recess 83 is, for example, 60 mm, and is preferably the same as the diameter of the opening 44 of the loading member (loading plate) 43 described later.

The upper mold 82 is connected to a slide rod of a first lifting device 85 such as a cylinder, and is configured to be able to rise and fall. In addition, the first lifting device 85 is installed on a vertical position adjustment device 86 for adjusting the descending stop position when the upper mold 82 descends. The vertical position adjustment device 86 is composed of a screw rod and a slide block that are screwed together. The vertical position adjustment device 86 is installed on the upper surface of a plate-shaped base plate 73 held on the frame 71.

A pair of cross-die pieces 88, 88 of the cross-die 87 have semicircular inner peripheral surfaces 89, 89 (see FIG. 7 ) that surround the outer skin material D and define the periphery thereof when the cross-die pieces 88, 88 approach each other. The cross-die pieces 88, 88 are respectively connected to a pair of slide bars at both ends of a driving device 91 provided on a pneumatic chuck or the like, and are configured to approach and separate from each other in the horizontal direction. Furthermore, the driving device 91 is connected to a slide bar of a second lifting device 93 such as a cylinder to raise and lower the cross-die 87. The second lifting device 93 is mounted on the base plate 73 via a mounting frame 75.

The inner material supply device 3 includes: a belt conveyor 7 for transporting an outer skin material D molded into a sheet shape and having a central portion thicker than other portions; a discharging portion 9 for supplying the inner material F to the upper surface of the outer skin material D; and a supply device 11 for supplying the inner material F to the discharging portion 9. The discharging portion 9 has a nozzle 15 that can be raised and lowered, and the nozzle 15 has a discharge port 17 at its lower end. The discharging portion 9 is configured to intermittently discharge a required amount of the inner material F from the discharge port 17 (see FIGS. 1 and 2 ).

The wrapping device 5 includes: a base 39; a plurality of devices mounted on the base 39, namely, a supply conveyor 23, an adjustment device 25, a support device 29, and a carry-out conveyor 31; and a control device 33 for controlling each of these devices. The supply conveyor 23 is a belt conveyor for supplying the outer skin material D carrying the inner material F to the adjustment device 25, and its front end 35 is configured to be able to move back and forth along the conveying direction R between an entry and exit position (not shown) and a standby position (see Figures 1 and 2).

In addition, referring to FIG. 5 and FIG. 6 , the adjusting device 25 includes: a bottom plate 41 that can be freely detached from the base 39, a perforated plate 43 (loading member, loading plate) and an adjuster 47. The perforated plate 43 is configured to load the outer skin material D thereon, and has a circular opening 44 at the center. The adjuster 47 includes 6 adjusting pieces 45 arranged at equal intervals in the peripheral direction in a manner surrounding the central opening 44. The perforated plate 43 is detachably (replaceably) mounted on the bottom plate 41, and the diameter of the opening 44 is selected to correspond to the size of the filling food P to be formed.

Each adjusting piece 45 is rotatably supported on the pivot 49, connected to each other by a connecting rod mechanism 51, and synchronously swung by an appropriate driving device. As shown in Figures 11B and 12B, the adjusting piece 45 is arranged on the common upper surface of the bottom plate 41 and the orifice plate 43, and is preferably arranged slightly apart from the upper surface (Figures 11B and the like are shown in a contact state). The adjusting piece 45 has an inner side surface 451 facing the center (inner side) of the opening 44 of the orifice plate 43. The adjuster 47 is configured to expand or shrink the area 61 surrounded by the inner side surface 451 of each adjusting piece 45 to perform an opening and closing action.

11B and 12B, the inner side surface 451 of the adjusting piece 45 includes: a first inner side surface 451A which is slightly inclined inwardly as it extends upwardly from the bottom surface 45U of the adjusting piece 45 in order to form a body portion PA of the stuffed food P; a second inner side surface 451B which is inclined more inwardly than the first inner side surface 451A as it extends upwardly from the first inner side surface 451A in order to form a shoulder portion PB of the stuffed food P; and a third inner side surface 451C which reaches the top 45T of the adjusting piece 45 from the second inner side surface 451B. The inner side surfaces 451 of the adjusting pieces 45 are gathered together to form a hole surrounded by the adjusting pieces 45 , which is hereinafter referred to as a through hole 63 .

The support device 29 is a belt conveyor disposed below the adjustment device 25, and is configured to support the central portion DC of the outer skin material D constituting the bottom surface of the stuffed food P and transport the stuffed food P to the unloading conveyor 31. The support device 29 has a ring-shaped conveyor belt 29A that is hung on a plurality of rollers and intermittently driven. The support device 29 is configured to be able to rise and fall, and for this purpose, for example, it is linked to a driving device such as a servo motor. The rising end position, the falling end position and the rising and falling speed of the support device 29, or the driving timing or driving speed of the conveyor belt 29A are adjustable (see Figures 1 and 2).

The unloading conveyor 31 is a belt conveyor disposed adjacent to the downstream side of the support device 29 that has been lowered to the lowering end position. The unloading conveyor 31 receives the stuffed food P from the support device 29 and unloads it to the downstream side (see Figs. 1 and 2).

Next, the forming steps of the stuffed food P of the forming device 1 of the first embodiment of the present invention are described. A raw dough ball DB of a predetermined weight is cut from a block of raw dough for food, formed into a circular shape, and supplied to the stretching device. The raw dough ball DB is stretched by the stretching device 95 to form a circular and flat outer skin material D. The width W of the outer skin material D is measured by the alignment device 97 disposed between the stretching device 95 and the outer skin material molding device 2, and the outer skin material D is aligned so that the center position in the width direction is consistent with the center position of the upper mold 82, and then supplied to the belt conveyor 81 of the outer skin material molding device 2. Based on the command from the control device 33, the belt conveyor 81 temporarily stops at a position where the center of the length L of the outer skin material D coincides with the center of the upper mold 82 to align the outer skin material D (loading step of the outer skin material D) (see Figures 1 and 2).

Referring to Figs. 7A and 7B, the second lifting device 93 is activated with the cross-die pieces 88 and 88 separated, so that the cross-die 87 is lowered to a position (lowering stop position) where the bottom surfaces of the cross-die pieces 88 and 88 slightly touch the conveying surface of the belt conveyor 81. Referring to Figs. 8A and 8B, the driving device 91 is activated so that when the cross-die pieces 88 and 88 that are lowered to the front and rear of the conveying direction R of the outer skin material D are close to each other, the cross-die pieces 88 and 88 surround the outer skin material D and correct the outer shape of the outer skin material D into a circular shape (alignment) by the inner peripheral surfaces 89 and 89. Referring to Figs. 9A and 9B, the first lifting device 85 is activated to lower the upper mold 82 to a predetermined position. The outer skin material D is deformed in accordance with the space formed by the belt conveyor 81, the upper mold 82 and the cross mold 87, thereby being molded into a thin sheet-like and roughly circular shape with a central portion DC thicker than the peripheral portion DD (molding step of the outer skin material D).

Referring to Fig. 10A and Fig. 10B, the first lifting device 85 is started to raise the upper mold 82 and wait at the rising stop position. In addition, the driving device 91 is started to separate the cross mold pieces 88, 88 from each other, and the second lifting device 93 is started to raise the cross mold 87 and wait at the rising stop position. The belt conveyor 81 is started to transport the outer skin material D to the inner material supply device 3.

Next, the belt conveyor 7 of the inner material supply device is stopped at a position where the center of the outer skin material D coincides with the center of the discharge port 17 of the nozzle 15, and the transportation of the outer skin material D is temporarily stopped. A predetermined amount of inner material F is discharged from the discharge port 17 of the nozzle 15 onto the outer skin material D, and then the inner material F is cut off from the nozzle 15, thereby placing the inner material F on the outer skin material D (inner material loading step, or inner material configuration step). The outer skin material D configured with the inner material F is transported to the supply conveyor 23 of the coating device 5 by the belt conveyor 7 (see Figures 1 and 2). In the plane display, the diameter of the discharged inner material F is preferably smaller than the diameter of the opening 44 of the orifice plate 43.

The front end 35 of the supply conveyor 23 moves and stops at the extended in-and-out position in a manner of covering the upper part of the regulator 47. Furthermore, the outer skin material D is conveyed to a position where its center coincides with the center of the area 61 surrounded by the regulator 47, that is, the center of the opening 44 of the orifice plate 43, and stops temporarily there.

Referring to FIG. 11A and FIG. 11B , the front end portion 35 is retracted to the standby position in one go, and the outer skin material D placed on the front end portion 35 is dropped into the area 61 surrounded by the adjuster 47 and transferred onto the orifice plate (loading member, loading plate) 43 (transfer step). Specifically, the outer skin material D carrying the inner material F is dropped into the through hole 63, and initially, the peripheral portion DD of the outer skin material D is made to land on the orifice plate 43. Then, the central portion DC of the outer skin material D carrying the inner material F is passed through the opening 44 of the orifice plate 43 and supported on the support device 29 which is standing by at a predetermined distance from the upper surface of the orifice plate 43. At this time, the peripheral portion DD of the outer skin material D is bent and made to stand upright from the perforated plate 43 by the contact between the portion near the central portion DC of the peripheral portion DD of the outer skin material D and the inner peripheral surface of the opening 44. In this way, the bottom surface PU of the stuffed food P is formed. In addition, the peripheral portion DD is gathered at the center by standing upright upward, and the plane is deformed into a wave shape (standing step).

The plurality of adjusting pieces 45 are synchronously rotated toward the center by the connecting rod mechanism 51 (the area 61 surrounded by the adjustment). Referring to FIG. 12A and FIG. 12B , the adjusting piece 45 is closed to the desired position without closing the through hole 63. When it stops temporarily, the inner side surface 451 of the adjusting piece 45 contacts the peripheral portion DD of the outer skin material D, and pushes the peripheral portion DD as a whole (the temporary stop step of the closing action). At this time, the peripheral portion DD of the folded wave is pushed inward by the inner side surface 451, and the peripheral portion DD is closely attached to the inner material F, thereby forming the remaining portion of the stuffing food P, and completing the stuffing food P (wrapping step).

To explain in more detail, the first inner side surface 451A of the adjusting piece 45 pushes the body PA of the stuffed food P, while the second inner side surface 451B pushes the shoulder PB of the stuffed food P. Furthermore, the head PC of the stuffed food P may or may not be pushed by the third inner side surface 451C of the adjuster 47 and may protrude upward from the through hole 63. The wrinkle pattern of the fold can be seen at the pushed peripheral portion DD. The head PC of the stuffed food P is not covered by the outer skin material D, so that the inner material F is exposed. In the first embodiment, the bottom surface PU of the stuffed food P is supported by the supporting device 29, and the body portion PA and the shoulder portion PB are subjected to a pushing action by the adjuster 47 (pushing step).

The adjusting piece 45 is rotated in the opposite direction to release the stuffed food P, so that the supporting device 29 carrying the stuffed food P is lowered to the lowering stop position. In addition, the stuffed food P is transferred from the supporting device 29 to the unloading conveyor 31 and unloaded to the secondary forming device or the heat treatment device (unloading step).

Next, referring to Figs. 13 to 16, a forming device 101 for a stuffed food P according to a second embodiment of the present invention will be described. In the forming device 101 according to the second embodiment, components identical to those of the forming device 1 for a stuffed food P according to the first embodiment are given the same reference numerals as those of the forming device 1, and a detailed description of the forming device 101 will be omitted. The forming device 101 includes an inner material supply device 103 and a covering device 5.

The inner material supply device 103 includes a supply device 11 disposed on the upper surface of the base 39 of the covering device 5. The nozzle 15 is disposed so that its center coincides with the center of the expansion and contraction area 61 of the regulator 47. In addition, the nozzle 15 is connected to a lifting device 65 such as a cylinder, and is configured to enter the area 61 and be lifted and lowered. The lowering stop position of the nozzle 15 is set higher than the upper surface of the orifice plate (loading member, loading plate) 43.

15 and 16 , the inner side surface 451 of the adjusting piece 45 includes: a first inner side surface 451A which is slightly inclined inwardly as it extends upwardly from the bottom surface 45U of the adjusting piece 45 in order to form a body portion PA of the stuffed food P; a second inner side surface 451B which is inclined more inwardly than the first inner side surface 451A and is formed with a concave curved surface as it extends continuously upward from the first inner side surface 451A in order to form a shoulder portion PB and a head portion PC of the stuffed food P; and a third inner side surface 451C which reaches the top 45T of the adjusting piece 45 from the second inner side surface 451B.

Next, referring to Fig. 15 and Fig. 16, the forming step of the stuffed food P by the forming device 101 of the second embodiment of the present invention is described. In the second embodiment, the outer skin material D is, for example, a thin sheet of shaomei skin cut into a square of 60 mm on one side, and the inner material F is, for example, 35 g of stuffing. The inner material F is covered with the outer skin material D to form a shaomei with stuffing P.

The outer skin material D is placed manually on the supply conveyor 23 of the wrapping device 5. The supply conveyor 23 performs the same operation as described in the first embodiment, dropping the outer skin material D into the area 61 surrounded by the regulator 47 and transferring it onto the orifice plate (loading member, loading plate) 43 (transfer step).

Start the lifting device 65 and lower the nozzle 15 to the lowering stop position. The nozzle 15 stops above the outer skin material D, and then discharges the required amount of inner material F from the discharge port 17 (inner material loading step, or inner material configuration step). As shown in Figures 15A and 15B, the inner material F is discharged to the center of the outer skin material D, and the central portion DC of the outer skin material D is pressed through the opening 44 of the orifice plate 43, so that the central portion DC of the outer skin material D is supported on the supporting device 29. At this time, the peripheral portion DD of the outer skin material D is erected upward from the orifice plate 43 in the same manner as in the first embodiment. In this way, the bottom surface PU of the stuffed food P is formed. In addition, the peripheral portion DD is deformed into a waveform in the plane display (erecting step). After that, the nozzle 15 is raised to the rising stop position (see Figure 15).

The connecting rod mechanism 51 is used to make the multiple adjustment pieces 45 rotate synchronously toward the center (the area 61 surrounded by the adjustment). Referring to Figures 16A and 16B, the adjustment piece 45 is closed to the position where the through hole 63 is not closed in the plane display. When it stops temporarily, the inner side surface 451 contacts the peripheral portion DD of the outer skin material D and pushes the entire peripheral portion DD (the temporary stop step of the closing action). At this time, the inner side surface 451 pushes the folded wave-shaped peripheral portion DD inward, and the peripheral portion DD is closely attached to the inner material F, thereby forming the remaining portion of the stuffing food P, and completing the stuffing food P (wrapping step).

To explain in further detail, the first inner side surface 451A of the adjusting piece 45 pushes the body PA of the stuffed food P, and the concave second inner side surface 451B pushes the shoulder PB and the head PC of the stuffed food P. The wrinkles of the folds can be seen in the pushed peripheral portion DD. In addition, the head PC of the stuffed food P is not covered by the outer skin material D, so that the inner material F is exposed. In the second embodiment, the stuffed food P is placed on the supporting device 29, and the bottom of the stuffed food P is surrounded by the opening 44 of the perforated plate 43, and the part of the stuffed food P located above the upper surface of the perforated plate 43 is pushed by the inner side surface 451 of the adjuster 47. That is, the stuffed food P is subjected to a pushing action substantially all around, and is formed to imitate the space formed by the components surrounding the stuffed food P (pushing step).

As can be understood from the above description, according to the present invention, the peripheral portion DD of the outer skin material D standing upward from the loading member (loading plate) 43 can be pushed against the inner material F by the inner side surface 451 of each adjusting piece 45 by the closing action of the adjusting device 47 including a plurality of adjusting pieces 45. In addition, during this pushing, the peripheral portion DD of the outer skin material D can be folded into a plane and deformed into a wavy shape. Therefore, a relatively simple structure can be used to form a filling food P in which the outer skin material D is closely attached to the inner material F.

Although the description of the forming device 1, 101 of the embodiment of the present invention is roughly as described above, the present invention is not limited thereto, and various changes can be made within the scope of the patent application. For example, in the above embodiment, although it has been described that the inner surface 451 of the regulating piece 45 is formed by three inner surfaces, for example, the third inner surface 451C can be omitted, and the related structure can be used to push the stuffed food P from the outside to make the outer skin material D close to the inner material F. In addition, when the length (height) of the first inner surface 451A is set to be longer, it can be formed into a long body part PA, so various shapes of regulating pieces can be used corresponding to the shape of the stuffed food P.

Furthermore, the size of the area 61 can be adjusted by controlling the closing action of the regulator 47 to form filling foods P of various sizes.

Furthermore, although the shape of the outer skin material D is described as circular or square, the shape of the outer skin material D may be a polygon such as a regular hexagon or other shapes, and may be selected according to the desired covering state of the outer skin material D at the head PC and the shoulder PB of the stuffed food P. Furthermore, the capacity of the inner material F and the size of the outer skin material D may be selected, so that the stuffed food P is formed such that the inner material F is exposed at the head PC, or the stuffed food P is formed such that the outer skin material D completely covers the inner material F.

In the above description, the outer skin material D is a sizzling dumpling wrapper formed into a sizzling dumpling with a stuffed food P. However, for example, the outer skin material D may also be a raw dough or a derived dough for Chinese stuffing, formed into a variety of stuffed foods with an inner material F being a Chinese filling or a fruit filling.

In the above description, the central portion DC of the outer skin material D is molded thickly using the upper mold 82 and the horizontal mold 87 of the outer skin material molding device 2, but the outer skin material molding device 2 may be omitted to mold a flat outer skin material, or other configurations may be used to mold the central portion DC of the thick outer skin material D. For example, when rolling a continuous strip of raw dough with opposing rollers, a roller having a concave portion formed on the peripheral surface may be used, and after the strip of raw dough is molded into a thicker portion of the raw dough thickness at a predetermined interval, the raw dough block is cut to form the outer skin material D.
