Weight Grader

Multi-stage weight belt grader is mainly used for automatic quantitative weighing and sorting of seafood, aquatic products, meat, poultry and other products. Each product is weighed individually and then sorted to the specified weight level according to the target weight setting automatically. It provides the degree of standardization of the product, to replace manual weighing and sorting efficiently.      

It can sort products of different weight to different operation line, and can fully display the production data such as production quantity, batch tracking, total weight, effective weight, and reject sorting weight.      


1) Full waterproof design with multiple waterproof protection, which can be flushed and cleaned directly

2) The 10-inch full-color touch screen is clear, bright and fully intelligent; the humanized button design will reduce mis-operation         

3) The Chinese/English bilingual tutorial mode is convenient for learning and operation.

4) It builds production records to record the number of each level, detailed data of weight and ratio, real-time reports. The data can be saved in U disk and then connected to other intelligent communication equipment.
