The Vertical Whitening Machine model BVZ is an excellent solution for rice millers who wish to obtain high productivity. The vertical design of this unit guarantees low grain breakage, minimum damaged tips and uniform whitening. Besides, it has high production capacity and low power consumpition for rated capacity. Based on the friction action principle the rice, after passing the charge hopper, is fed into the machine whitening chamber in a descendent way by means of the feeding screw. On entering into contact with a cylindrical abrasive surface, part of the germen and the bran layer is removed from the rice kernels. The system consisting of a fan and cyclone sucks off the bran through the slots of the screen.
Four longitudinal metallic brakes (resistance bars) disposed in a radial way have two purposes, which are: The retarding effect which have the purpose of controlling the speed of the rice flow in the whitening chamber; and the positining effect, which ensures that grains rotate on their own axis. These two effects permit uniform whitening and also preventthe from breaking.
• High production capacity and low power consuption;
• Small installation space required;
• Uniform whitening;
• Low grain breakage and damaged tips rates;
• Precise and easy adjustment of the whitening degree;
• Wear parts are easily exchangeable.
