Peanut Sheller using Screw Conveyor

Abstract

Efforts are made to conserve our energy resources taking into account the rateat which it is depletingdue to the rising demands. Our proposed project makes an attempt to use manpower in crushing the shell of a peanut. The Sheller available in our vicinity uses electric energy; therefore using manpower ensures preservation of our resources to some extent. Lack of groundnut processing machines, especially groundnut Sheller, is a major problem of groundnut production, especially in our country India. The sprockets of a bicycle are rotated by pedaling action and this rotary motion is used to rotate the shaft of a screw conveyor. The peanut get crushed in between the flights around the shaft and the casing of the conveyor. Peanuts are delivered into the conveyor with the help of a hopper. Pedal-operated peanut sheller using screw conveyor with 10mm clearance between flights and casing crushes shells at 150 kg/hr capacity. Overall efficiency 79.61% with deflection under 3mm. The manually operated peanut Sheller by using screw conveyor is easy to use hence does not require any skilled person. It is operated by pedaling action hence ensures comfort as compared to hand operated machines.
