The machine uses the belt to convey and discharge the material, and the belt conveys and selects. The operation station is divided into two sides, and the worker picks out the waste and sundries and puts them into the waste place. This machine is mainly used for the selection of vegetables, fruits and other materials. The machine has the advantages of good selection effect and easy operation. In the production line, the equipment is usually used in conjunction with other equipment with high requirements on the feeding port to meet the needs of production automation. (The unqualified materials and the damaged parts on the materials need to be removed manually) The whole machine is made of 304 stainless steel material, and the high-pressure water pump is used, and the cleaning effect is better.
