Abstract

This utility model discloses a screening and soaking device for soybeans used in the production of dried tofu sheets, relating to the technical field of dried tofu sheet production equipment. The device includes a housing with a spoiled soybean box fixedly installed on one side. The interior of the housing communicates with the interior of the spoiled soybean box. A discharge port A is provided at the bottom of the housing, and a discharge port B is provided at the bottom of the spoiled soybean box. The device uses a pushing component to push the spoiled soybeans floating on the water surface, moving them to the inside of the spoiled soybean box for cleaning and preventing them from affecting the quality of the dried tofu sheets. Through a transmission component, during the cleaning process, the pushing component also drives the rotating rod A, the spiral blade A, and the stirring frame to rotate. The rotation of the spiral blade A pushes the soybeans, evenly conveying them into the water, while the rotation of the stirring frame agitates the soybeans, ensuring even soaking.
