Development of a versatile ground nut shelling machine with built-in roaster.

Groundnut is a valuable and important crop which is cultivated almost throughout theworld. The groundnut must be cracked to obtain peanut so it can be further used for extraction of oil and used in food items. The traditional way of removing peanut from groundnut is to crackit with hand but when a large number of nuts have to be work on this method is of time consuming the prototype contains mainly of a main frame, a rubber tyre, a wire mesh, and a hopper. The rubber tyre used was a worn-out rubber tyre. Tyre treads were cut to prevent excessive slip during operation. Wheel rim and inner tube were also used. The purpose of using the tyre and concaveis narrowest at the midpoint of the concave and wider toward the inlet and outlet. This clearanceis adjustable in a vertical direction. An opening of the hopper is also adjustable so that feed ratecan be inner tube was to study the effect of tyre inflation on shelling. [ABSTRACT FROM AUTHOR]
