At least a portion of the rotating device is disposed within the cleaning pool 10. The cleaning tub 20 has a hollowed-out wall structure. After being placed within the cleaning pool 10, the bottom of the cleaning tub 20 is connected to the rotating device disposed within the cleaning pool 10, and the rotating device can drive the cleaning tub 20 to rotate.

[0035] Before washing, pour the soybeans into the washing bucket 20, then place the washing bucket 20 into the washing tank 10, connecting the bottom of the washing bucket 20 to the rotating device inside the washing tank 10. Water is drained into the washing tank 10 through the inlet 11. Because the side wall of the washing bucket 20 is perforated, water from the washing tank 10 can also enter the washing bucket 20. The rotating device is activated, causing the washing bucket 20 to rotate, and the water inside the washing bucket 20 is also rotated, washing the soybeans under centrifugal force. It should be noted that the perforated design of the washing bucket 20 allows water to enter while preventing soybeans from easily leaking into the washing tank 10. After washing, the wastewater in the washing tank 10 is discharged through the outlet 12. The washing bucket 20 is then removed from the washing tank 10 for the next stage, or fresh water is drained into the washing tank 10, and the washed soybeans are directly soaked in the washing tank 10.

[0036] This utility model uses a hollowed-out washing bucket 20 to hold soybeans, which are placed in a washing pool 10 and connected to a rotating device. The soybeans are centrifugally washed under the drive of the rotating device. Water can be discharged into or out of the washing pool 10. After washing, the washing bucket 20 can be moved away.
