JPH11187821A - Extrusion portion structure of device for extruding ice cream - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide the extrusion portion structure of a device for extruding an ice cream, capable of readily releasing the ice cream from a valve member, when the extrusion is finished. SOLUTION: An extrusion pipe 39 connected to the extrusion port of a pack is projected from a heat-insulating door, and an opening or closing pipe 40 into which a valve member 47 is fit is disposed on the tip of the extrusion pipe 39 in a mutually communicating state. A semi-spherical depression 51 is formed on the lower surface of the value member 47. When an ice cream A is extruded, the ice cream A is extruded from the extrusion pipe 39 to the extrusion port 42, while a space S is formed between the depressed portion 51 of the valve member 47 and the ice cream A. When the valve member 47 is lowered after the finish of the extrusion, only the ice cream A charged on the side of opening or closing pipe 40 in a state leaving the space S is extruded. The valve member 47 is lowered to a position for closing the injection port 42, and subsequently the ice cream A is pulled by a method comprising, for example, lowering a vessel for extruding the ice cream. The ice cream A is thus easily released, because the contact area of the ice cream A with the lower surface of the valve member 47 is small due to the existence of the space S and further because the adhesive force of the ice cream is weak.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a pouring section of a frozen dessert pouring device.

[0002]

2. Description of the Related Art As a conventional ice cream dispenser, a cooling cylinder is provided with a pouring cylinder in which a pack of ice cream is accommodated, and the cylinder is driven to compress the pack to discharge ice cream. What discharge | ejects from the injection | pouring part provided in the outer wall of the cooling storage room is known. As shown in FIG. 6, the structure of the pouring section is generally such that a pouring pipe a connected to the discharge port of the pack is protruded laterally from the outer wall of the cooling storage chamber, and a tip of the pouring pipe a. A vertically open / closed pipe c fitted with a valve body b which is moved up and down by a lever operation or the like is connected in a communicating manner, and a spout d is formed at a lower end of the open / closed pipe c. And
When pouring out the ice cream A, the pack is compressed by the pouring cylinder, and the valve b of the opening / closing pipe c is positioned above the communication port e as shown by the solid line in FIG. When the ice cream A is lifted, the ice cream A discharged from the pack is pushed out from the discharge pipe a through the communication port e, below the opening / closing pipe c, and is discharged from the discharge port d into the cup.
When the proper amount is dispensed, the compression of the pack is stopped, and the valve body b is lowered to a position where the spout d is closed, as shown in FIG.

[0003]

Since the ice cream A to be poured has an appropriate hardness and stickiness, even if the valve body b is lowered to finish the pouring,
The adhesive force based on the surface tension acts to stick to the lower surface of the valve body b and cannot be easily peeled off. For this reason, the worker has cut off the ice cream A by rotating the cup as a whole. In this case, the ice cream A after being shredded often remains on the lower surface of the valve body b and the edge of the spout d. This remaining ice cream A
Melts and drops due to the influence of the external temperature, resulting in soiling the surroundings. Even if it does not melt out, if it remains as it is, it will not be good for hygiene or it looks bad, so after every pouring, ice cream A that remains in preparation for the next pouring
Work with a cloth or the like is required, which is troublesome.
The present invention has been completed based on the above circumstances, and an object of the present invention is to make it possible to easily peel frozen dessert from a valve body at the end of pouring.

[0004]

As a means for achieving the above-mentioned object, as a means for discharging a frozen dessert according to the present invention, a dispensing portion structure of a cooling dessert is provided in a cooling storage chamber equipped with a cylinder for dispensing frozen dessert. A discharge pipe connected to the discharge side of the discharge cylinder protrudes from the outer wall, and a vertical opening / closing pipe in which a valve body is slidably fitted is connected to a tip of the discharge pipe. The opening and closing is provided at the lower end of the opening and closing pipe, and the dessert of the frozen dessert is performed by raising the valve body above the communication port with the injection pipe in the opening and closing pipe, In a configuration in which pouring is completed by lowering the valve element to a position where the spout is closed, the lower surface of the valve element is formed on a surface having a concave portion upward. Having.

[0005]

The operation of the present invention is as follows. When pouring the frozen dessert, the pouring cylinder is driven, and the valve fitted to the opening / closing pipe is raised above the communication port. Then, the discharged frozen dessert is pushed out from the spouting tube through the communication port to below the opening / closing tube, and is spouted from the spouting port. During this time, since a concave portion is provided on the lower surface of the valve body, a space is formed between the concave portion and the frozen dessert poured out. When ending the dispensing of the frozen dessert, the driving of the dispensing cylinder is stopped and the valve body is lowered to the position where the spout is closed. Along with this, only the frozen dessert that has been cut off at the communication port and that has entered the opening / closing pipe side is pushed out to the spout port side. At this time, since the spout is opened at the lower end of the opening / closing tube, the frozen dessert does not receive enough pressure to fill the above-mentioned space, so that the frozen dessert is extruded with the space being formed. When the valve body reaches the position of the spout and stops, the frozen dessert tries to move away from the valve body, and at that time there is a space between the frozen body and the lower surface of the valve body, and the contact area with the lower surface of the valve body is small. Since the adhesive strength based on the surface tension is also small, the frozen dessert easily peels from the lower surface of the valve body.

[0006]

As described above, according to the present invention, frozen dessert can be extruded without leaving it on the lower surface of the valve at the end of pouring. Therefore, it is possible to prevent the remaining frozen dessert from being melted and dripped as in the related art, thereby preventing the surroundings from being soiled, and to eliminate the troublesome work of wiping off the remaining frozen dessert one by one in preparation for the next pouring.
