The invention discloses a soybean cleaning and peeling device and process, the device comprises a first elevator, one side of the first elevator is located in a granary, the other side of the first elevator is provided with a rotary vibration sieve, and one side of the rotary vibration sieve is provided with a first winnowing machine. The broken beans and deflated beans with small particle size are screened out for separate peeling operation, the soybean peeling rate and utilization rate are greatly improved, stage treatment is achieved, the working efficiency is improved, surface treatment is conducted through the skin brushing machine, the content of dust on the surfaces of soybeans is effectively reduced, the economic value of by-products is improved, the cleaned dust is collected through the cloth bag dust collector, flying dust is effectively avoided, by adopting two-time peeling and a light grinding and fine pressing process, the breaking of the bean halves can be reduced, the yield can be improved, meanwhile, two-time color sorting is adopted and matched with checking, moldy grains and mixed beans are effectively removed, clean and high-purity bean halves are provided for subsequent processing, and the later workload can be reduced.
