Dev Raj Hi-Tech Machines Limited supplies Tray Type Paddy Separator. Dev Raj Hi-Tech Machines Limited is an ISO 9001 certified company. The Tray Type Paddy Separator is made of several dimple trays which are set in a reciprocating motion during operation. These trays are inclined in both longitudinal and latitudinal directions. The latitudinal inclination is stationary, while the longitudinal inclination can be adjusted. The effect of separation is due to the fact that trays provide a pre-determined friction. The difference in gravity and roughness of the grain surface enables the separation. Smoother the grain surface and heavier the gravity, it will sink to the lower part of the tray while rough surface paddy will go upward. Compared to compartment type separators, Tray Type Paddy Separator`s installation requires less power and space. The weight of the machine is very less and it is capable of separating paddy and husked rice regardless the shape & variety.
