Design of simple corn shellers for farmer house [electronic resource].

Includes references.

The objective of present investigation is to design simple farmer house corn shellers. Two simple maize shellers, hand and motor type were fabricated and tested to obtain the torque and power requirements for husked corn ear shelling process at different moisture contents. The study revealed the following results: 1- Hand sheller: When grain moisture content decreased from 14 to 10 %, grain visible breakage and/or cracks as well as unshelled grain were negligible at all study variables, while grain cleaning efficiency decreased from 99.81 to 99.52 % and torque needed for shelling decreased from 0.12 to 0.04 N.m, and the performance rate increased from 21 to 24 kg/h. - The house hand sheller may be recommended for use with an economical advantage (operating cost of one ton + cost of the grain losses) of 90.96 LE/ ton compared to manual shelling, which would cost 142 LE/ton.
