According to a third aspect of the present invention, in the steamed food production apparatus according to the second aspect, the heating means 8 provided above the outside of the steaming duct 1 comprises an infrared burner 11.

According to a fourth aspect of the present invention, in the steamed food producing apparatus according to the first aspect, the heating means 8 is incorporated in the steaming duct 1.

According to a fifth aspect of the present invention, in the steamed food producing apparatus according to the fourth aspect, the heating means 8 incorporated in the steaming duct 1 comprises an electric heater 21.

[0009]

FIG. 1 is a longitudinal sectional view showing a steamed food producing apparatus according to the present invention, and FIG. 2 is an enlarged transverse sectional view of the steamed food producing apparatus. In this drawing, reference numeral 1 denotes a steaming duct made of stainless steel, which is formed by an upper wall plate 2, left and right side wall plates 3, 3 and front and rear wall plates 4, 5 in a box shape having an open bottom. A steam supply port 6 is provided at a front end of the plate 2 and a steam discharge port 7 is provided at a rear end thereof. 8 is a heating means for heating the steaming duct 1 to 100 ° C. or higher in order to prevent condensation of steam on the inner surface of the steaming duct 1.
Is provided on the upper side outside. 9 is a food material 10
Is a conveyor installed at a position so as to block the bottom of the steaming duct 1 in order to convey the steam from the rear end to the front end in the steaming duct 1.

Although not shown, the steam supply port 6 is connected to a steam supply pipe extending from a steam supply source. The heating means 8 is composed of a plurality of infrared burners 11, which are arranged at a certain height above the upper wall plate 2 of the steaming duct 1, as shown in FIG. Are arranged and fixed at regular intervals,
Upper wall plate 2 of steaming duct 1, each side wall plate 3, front and rear wall plates 4,
5. The steam supply port 6 and the steam discharge port 7 are each heated to 100 ° C. or more.

The conveyor 9 is made up of a net conveyor.
The transport belt 12 is run at a low speed in the direction of the arrow in FIG. 1 by driving the pulley 13 by a motor (not shown). As shown in FIG. 2, the upper side transport band 12 on which the food material 10 is placed is, for example, a net support plate 1 made of a perforated plate.
7 is slidably supported.

[0012] In the production of steamed food by the steamed food production apparatus configured as described above, the steam supply port 6 through 9
The food material 10 is placed on the upper conveyor belt 12 of the conveyor 9 while supplying steam at 0 ° C. to 100 ° C. into the steaming duct 1, and is slowly moved from one end to the other end in the steaming duct 1. When being conveyed, each food material 10 is steamed by steam before passing through the steaming duct 1, and is carried out as steamed food.

When the food material 10 is passed through the steaming duct 1 to produce steamed food, the entire steaming duct 1 is heated to 100 ° C. or higher by the heating means 8. Is prevented from condensing on the inner surface of the duck 1, so that no water drops fall on the food material 10 passing through the steaming duct 1 by the conveyor 9, and each food material 10 is uniformly steamed by the steam supplied from the steam supply port 6, whereby a high-quality steamed food is continuously produced. The steam supplied into the steaming duct 1 is discharged from the steam outlet 7.

FIG. 3 shows an embodiment in which the heating means 8 is incorporated in the steaming duct 1. In this case, the heating means 8 comprises an electric heater 21.
That is, the steaming duct 1 shown in FIG. 3 is formed in a box shape with an open bottom, but the duct 1 itself is formed in a hollow shape, and an electric heater 21 is inserted into the hollow portion as shown in the figure. Deployed. Other configurations are the same as those in the embodiment of FIG.
A conveyor 9 for transporting the "0" is provided. Although not shown, the steam duct 1 also has a steam supply port and a steam discharge port.

According to the heating means 8 incorporated in the steaming duct 1 as shown in FIG. 3, the steamed food manufacturing apparatus can be made compact and small. Further, since the heating means 8 is composed of the electric heater 21, it is easy to incorporate the heating means 8 into the duct 1, and the temperature control is easy.

The steamed food production apparatus described with reference to FIGS. 1 to 3 shows a case in which a food material 10 is steamed while passing through a steaming duct 1 by a conveyor 9. The food material 10 may be steamed by the steam supplied into the steaming duct while the still foodstuff 10 is placed in the steaming duct and kept stationary.

Although not shown, a paste-like dough such as flour is applied to an outer peripheral surface of a heated rotating drum rotating at a low speed, and the dough is baked on the outer peripheral surface of the drum.
The present invention is also applicable to a case where the dough is steamed from the outer periphery and steamed to finish it into a sheet-like food. That is, a steaming duct is provided to cover the dough formed into a sheet on the outer peripheral surface of the heated rotary drum along the outer periphery thereof. By providing heating means for heating the steaming duct to a predetermined temperature or higher in the food manufacturing apparatus in which the sheet-like dough is steamed from the outer peripheral side by steam supplied into the steaming duct, condensation of steam on the steam duct inner surface can be prevented. As a result, water droplets do not drop onto the sheet-like dough on the outer peripheral surface of the drum, and a high-quality sheet-like food can be manufactured.

[0018]

According to the first aspect of the invention, since the heating means for heating the steaming duct to a predetermined temperature or higher is provided, the steam supplied into the steaming duct is condensed on the inner surface of the duct. This prevents water drops from falling on the food material placed in the steaming duct or the food material passing through the steaming duct, and the food material is steamed as desired by the steam supplied into the duct. Processed into a good quality steamed food.

If the heating means is provided above the outside of the steaming duct, the entire steaming duct can be easily heated to a required temperature.

As the heating means provided above the outside of the steaming duct, an infrared burner is preferable, and according to this infrared burner, the steaming duct can be heated more effectively.

By incorporating the heating means inside the steaming duct, the steamed food production apparatus can be made compact and small.

When the heating means is incorporated in the steaming duct, if an electric heater is used as the heating means, the heating means can be easily incorporated in the steaming duct and the temperature can be easily controlled.
