Bean Preliminary Cleaning Line Soybean Cleaning Machine

　　Bean preliminary cleaning equipment introduction:

　　Bean preliminary cleaning equipment usually refers to the plant which can process beans preliminary cleaning. It is an automatic bean processing line integrated with cleaning, destoning, selecting, brushing, grading, color sorting and winnowing processes. The line is in double layer steel structure with equipments arrangement. It uses electric centralized control system, up to continuous automatic operation. The bean preliminary cleaning equipment can be applied in almost all of the beans cleaning, such as soybean, kidney bean, mung bean, navy bean, sword bean, pea, cowpea, chickpea, butter bean,lentil,broad bean, black soya bean, small red bean and so on.

　　Bean preliminary cleaning equipment technology and features:

　　The line includes processes of once magnetic separation, twice cleaning and destoning. Materials are conveyed by elevators and 2 groups of aspiration systems are used to dedust. It includes 2 sifting processes to remove big and small impurities in the raw bean. Then the destoner fully removes the stones. The magnetic separator increases purity of the finished products to guarantee good taste by removing metal impurities so as to prevent them from mixing into the final beans.

　　Features of processing technology: once selection and twice bushing processes lead to lustrous beans, increasing high yield, low brokens and uniform granules. After color sorting, the beans up to national standard can be packaged.

　　Once selection process removes impurities in the bean; twice polishing processes dedust the materials to increase lustrousness; The vibration sifter grades out brokens in the finished products while the complete fine beansare conveyed to color sorter. The sorted kernels are selected again and then go to packaging cabinet. Finished products go to belt conveyor to be manually selected and then mechanically packaged through buffering bin.

　　Bean preliminary cleaning equipment products and yield:

　　Finished product: fine bean(depending on impurities in the raw bean)

　　Fine bean: 90-96%

　　Broken kernel: 2-3%

　　Impurity: 2-7%
