(Operation) Next, the operation will be described.

First, a predetermined amount of hot water having a predetermined temperature is supplied into the hot water storage tank 3 through the supply pipe 20. Then, the hot water in the hot water storage tank 3 has a communication hole.
It enters the dipping chamber 1 through 15 and becomes almost level with the hot water surface of the hot water storage tank 3.

Next, in advance, for a predetermined time (in the embodiment, about 30 to 60
Min) Grains (hereinafter referred to as rice in the following examples) dipped in a bath (not shown) are supplied into the tank 6 through appropriate means, and cleaned in the tank 6.
Supply low pressure saturated steam at 100 ° C and steam for about 30 minutes. Then, when the shutter 5 is opened, the rice in the tank 6 drops and is conveyed to the dipping section B side by the conveyor 26.
It always contains a certain amount of soaked rice. Therefore, since the rice in the tank 6 gradually drops while being steamed with steam, the steaming work can be continuously performed thereafter. Then, the rice discharged from the conveyor 26 falls into the dipping chamber 1 and is transferred to the secondary cooking part C side by the grain transfer device 2, but during this time (about 7 minutes), it is immersed in hot water of about 85 ° C. And take hot water. Then, it is separated from the hot water and the endless belt 21 is removed from the immersion chamber 1.
The rice discharged above is conveyed to the take-out side by the endless belt 21 and then collected by the conveyor 25. During the conveyance, the rice floats up through the holes of the endless belt 21 and is cleaned. Steamed under low pressure saturated steam (about 15
Minutes). Further, since the agitator 24 moves the rice toward the take-out side at the transport start end portion, there is no stagnation of the rice and the quality is improved. Then, the cooked rice cooked in the secondary steaming section C and cooked is conveyed by the conveyor 25 to the next section (for example, the serving section).

In continuous grain processing operations, the outside air temperature (room temperature) is lower than that of the hot water, so the hot water in the hot water storage tank 3 has a predetermined temperature (about 85
℃) or less. Then, the hot water temperature sensor 19 detects this and outputs a warming command signal, and the control device receiving this signal is sent via the steam cleaner 27 (about 100
(° C) steam is supplied to the steam passage 17.

Since the bottom wall 14 of the hot water storage tank 3 is heated by this steam, the hot water temperature of the hot water storage tank 3 also rises. After that, when the hot water temperature reaches approximately 85 ° C., the control device stops the supply of steam.

Therefore, the difference in hot water storage temperature in the dipping chamber 1 can be reduced, so that the quality of the grains to be dipped can be stabilized. In addition, since the heating means is provided in substantially the entire width of the bottom wall 14 of the hot water storage tank 3 in the left-right direction, the effect of heating the hot water can be improved.
In addition, since the heating means is provided outside the hot water storage tank 3, even if rust or foreign matter is generated in the heating means, it does not enter the dipping chamber 1 and the commercial value can be increased. Further, since the left and right side walls 8 and 9 of the immersion chamber 1 and the guide wall 7 are surrounded by the hot water stored in the hot water storage tank 3, the influence of the change in the room temperature is small, and stable quality improvement is further achieved. Can be achieved.

(Effect) Since there is little change in the temperature of the hot water stored in the dipping chamber 1, the quality can be stabilized and the quality can be improved without the intrusion of foreign matter.
