Abstract

An apparatus for separating hulls from unhulled rice having a fixed rotating roll and a movable rotatable roll located in pressure contact with the fixed roll. A control rod connected to a biasing spring holds the movable roll in pressure contact with the fixed roll. An automatically operated control senses the biasing force of the biasing means and adjusts the biasing force to maintain substantially constant contact pressure between the fixed and movable rolls.
