The CB1M model is a mesh mechanical sorting module to work potato and onion. This module was thought to carefully handle the product across a metallic or rubber mesh that can be square or hexagonal, being the diameter under the client's choice. The sorting lines can have multiple linked modules and that way the client can work several sizes successively. The mesh can also be changed according to the client's needs. Underside the module there's a conveyer that removes the selected size from the line. The production capacity of this machine varies according to the width, length and applied speed.
