The pearler consists of a cylindrical abrasion rotor made up of a series of abrasion stone discs mounted on a horizontal shaft without any gap between them. The rotor so formed is mounted in a metal case with a clearance of 1.5 cm at the sides and around the bottom of the roller. Two screws of pitch length 1.5 cm each are provided at the inlet end. An aspirator is provided at the outlet end to suck and remove husk. Grains are fed at one end of the pearling unit at a uniform rate and collected at the other end. The level of grain inside the unit is adjusted during operation for efficient operation. This cycle of operation has to be repeated depending upon the extent of hull/seed coat to be removed. |
