The bottom opening of the rice washing container (6a) and the bottom plate are not completely sealed, allowing some water to leak out. As a result, the washed rice is drained out of the main body (1) from the drainage receiver (9) through the conveyor (7a) in sequence.

Such rice washing stops its operation until the turbidity of the waste water becomes less than a predetermined value and the drainage is completed. Thereafter, the conveyor is opened for a predetermined time and water is supplied into the rice washing container (6a).

A unit amount of rice and a corresponding amount of water are supplied into the rice cooker CI+1 while washing off the rice adhering to the rice washing container (6a) and the conveyor (7a). This operation is repeated until the specified amount of rice is reached. next.

The carrier (7a) is again swung to the drain side, water is supplied for a predetermined period of time, and post-cleaning is performed. The position of the carrier (7a) is detected by detection switches (8a) and (8b).

It is accurately controlled by a control device αj. At the same time as post-washing, the lid holding device α is operated, the retention of the lid α force is released, and the lid aη is closed by its own weight. on the other hand.

The rice in the rice cooker α1 is in a heaped state, and horizontal vibration is applied to the rice cooker αQ by a vibration table (not shown) installed at the bottom of the rice cooker t1. The rice in aQ is arranged evenly. Thereafter, a standby time is taken to soak the rice in water for a predetermined time, and power is supplied to the rice cooker a.
