Abstract

(57) [Summary] [Purpose] In a horizontal steaming device, when steaming heat treatment of brewing raw materials such as rice, wheat and soybeans stacked on an endless belt-shaped raw material transport belt during steaming Solve that. [Structure] In a horizontal steaming device for steaming raw materials stacked on an endless belt-shaped raw material transfer belt at normal pressure or under pressure, a side wall with which the raw materials come into contact has a heating structure.

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a horizontal steaming device that heats brewing raw materials such as rice, wheat, soybeans, etc. stacked on an endless belt-shaped raw material transport belt with steam during transportation.

[0002]

[Prior Art]

 The horizontal steaming device can be found in Jitsukaihei 1-178829, and you can refer to FIG. The apparatus has pulleys 1a and 1b on both left and right sides of a casing, and a porous raw material transfer belt 2 is stretched between the pulleys 1a and 1b in an endless state. One pulley 1b is connected to the motor so that the raw material transfer belt 2 can rotate. The raw material inlet 3 is located near the left pulley 1a, and the raw material outlet 4 is open to the outside of the casing beside the right pulley 1b. In the horizontal type apparatus for continuously steaming the raw material 5 laminated on the endless belt-shaped raw material transfer belt 2, the steaming raw material 5 is conventionally in contact with the heat-insulated side wall 6 as shown in FIG. It was

[0003]

[Problems to be solved by the device]

 In the structure in which the side wall 6 is simply insulated by the heat insulating material 7, dew condensation occurs on the side wall 6 with which the raw material comes in contact while the raw material is cooked and moved. The condensed water permeated the raw material, and there was a problem that it became a steamed raw material (rice cooked form) with excessive water content.

[0004]

[Means for Solving the Problems]

 In the present invention, such a problem is solved in the apparatus for steaming the raw material laminated on the endless belt-shaped raw material transfer belt 2 under normal pressure or pressure by providing the side wall with which the raw material comes into contact with a heating structure. . A preferred embodiment of this heating structure is a steam passage gap formed between the side wall in contact with the raw material and the apparatus main body, a steam pipe provided along the side wall in contact with the raw material, or a heater.

[0005]

[Action]

 With such a structure, the heating structure eliminates dew condensation on the side wall that comes into contact with the raw material, and prevents unevenness of water in the cooked raw material.

[0006]

【Example】

 FIG. 2 is a first embodiment of the present invention and is an enlarged sectional view taken along line AA in FIG. In this example, the steam passage 12 is provided between the side wall 10 and the inner wall 11 of the main body of the apparatus in the cooking chamber 9 to provide a heating structure. That is, the side wall is doubled and the steam passage is provided between them. While the raw material 5 laminated on the raw material transfer belt 2 is continuously cooked with the steam from the steam inlet 8a, a part of the steam heats the side wall 10 through the steam passage 12 and is discharged from the exhaust port 8b. Is done. In order to prevent steam from passing only through the steam passage 12, measures such as reducing the opening ratio of the transfer belt 2 are added.

FIG. 3 shows a second embodiment, and the side wall is a heating plate 14 with a built-in steam pipe 13 as a heating structure. Adjust the temperature of the heating plate with the temperature sensor 16 to prevent it from overheating. FIG. 4 shows a third embodiment in which the side wall is a heating plate 14 with a built-in heater 15. The heater is a cord heater. Of course, the temperature of the heating plate is adjusted by the temperature sensor 16.

[0008]

[Effect of the device]

 Since the horizontal steaming device of the present invention has no condensation on the side wall, it is possible to obtain a homogeneous steaming raw material, and as a result, high-quality koji or brewed products can be obtained.
