Then, the cold air passes through the peripheral gap 3 from the rear part of the storage hopper 2 through one side part to the front part between the front wall 4A and further through the other side part of the storage hopper 2 to the rear suction port. 7 and returned from the suction port 7 to the second part 5B of the external cooling unit 5.
The cold air flows around the upper part or the entire circumference of the storage hopper 2 without short-circuiting to the suction port 7, effectively cooling the inside of the storage hopper 2, and the cold air is lowered by natural convection during the flow. Thus, the air below the storage hopper 2 in the heat insulation box 4 is also cooled.
[0025]
Although the cold air supplied from the blowout port 6 rarely reaches the rice mill 13A directly, the rice mill 13A is surrounded by a sufficiently low temperature atmosphere and cooled, although slightly higher than in the storage hopper 2. Since the vicinity of the basket receiving container 37 at the lower part of the heat insulating box 4 is slightly higher than the inside of the storage hopper 2, the relative humidity is lowered.
When white rice is needed at home, the weighing means 20 is operated, the brown rice in the storage hopper 2 is fed from the discharge port 26 to the rice receiving container 37, and the rice mill 13A is operated to polish the rice. The rice milling machine 13 </ b> A is pulled out from the opening 14, and the rice milling net 38 is taken out from the jar receiving container 37. The rice bran may be removed every time white rice is taken out or every few times.
[0026]
Even if white rice and rice bran are left for a long time in the state immediately after milling, the inside of the heat insulation box 4 is sufficiently cooler than the outside air (a temperature suitable for storing rice), so the white rice is stored in the white rice in the air-cooled state. The prevention of mold and pests can be maintained, and the rice bran is in a low temperature and low humidity state, and can be prevented from adhering to the straw receiving container 37 while maintaining a smooth state.
