Sweet potato washing machine

Today I will take you to see the process of cleaning sweet potatoes with a roller cleaner. Look at this pile of sweet potatoes, just dug out of the ground. It’s covered with dirt and impurities. Now put them in the tumble washer. The drum cleaning machine starts to run, and its drum slowly rotates. The sweet potatoes are rolling in the roller as they turn. The water in the washing machine also flows, and the water and sweet potatoes rub against each other. Under the rotation of the drum, the soil that was originally tightly attached to the surface of the sweet potato began to fall off. The drum keeps turning and the water in the cleaning machine keeps circulating. Every tumble of sweet potatoes is a deep cleaning.
