Huller Machine

Huller is a machine which removes the hulls from the grains. It is a heavy duty machine for the preparation of edible grains like rice, wheat, pulses etc. It also polishes the rice and whiten it. It normally consists of grain grinder, rubber disk, steel washer etc.

How does a Huller work?
Grains are pressed between the rubber-faced disk and rotating disk and then rolled out. The soft rubber disk allows the hulls to be removed with minimal damage to the rice kernels. Natural rubber is used for the rubber disk because it has better abrasion resistance than synthetic rubber.

The hulling of the grain depends on the spacing between the stationary rubber disk and the rotating abrasive disk and uniformity of spacing between the disks. The huller blade regulates the severity of the process and is adjustable to suit the various milling conditions of the grains to keep the breakage of the rice to a minimum level. The hullers are either diesel driven or powered by electric motor. The huller also consists of a steel drum with attached leather thongs which polishes the grains. The hullers can be mounted on high or low stands depending upon the requirement and working space.
