VERTICONE Whitening Machine for Rice and other Cereals

Vertical Rice Whitener Type VPC 470
(patent pending)

The whitening degree is influenced by the following parameters:

1. Throughput capacity per hour
2. Gap adjustment between whitening stones and sieves
3. Position of the brakes

Vertical whitening from top to bottom. The Verticone VPC 470 operates with abrasive conical whitening discs with air-feed openings in between. The small diameter of the conical whitening rotor is placed at the top, right underneath feeding section while the big diameter is placed at the bottom, before the outlet section.

The product is conveyed to the machine by a vertical feeding pipeline. A conical distributor within the round inlet bin devides the product uniformly to the feeding worm which feeds the product into the whitening chamber.

The counterpressure disc which is adjustable connected by three springs in the outlet section causes an uniform filling ratio and uniform pressure within the entire working chamber.

This ensures a gentle and uniform whitening of the product. Air cools the product during the whitening procedure and supports the discharge of the bran. The bran is removed by a separate pneumatic bran aspiration system.
