| Abstract | ||||
| The processes of separating and cleaning the corn cobs from the husks and other impurities is one of the most important post-harvest processes. This machine consists of the following main parts: frame – husking unit – feed opening – power source. Performance of the machine was tested and evaluated to determine the optimal conditions for its operation by studying the following factors: four rotating speeds for husking cylinder, two lengths of husking cylinder and two husking cylinder clearance at two types of corn. The feed opening tilt angle was 144 o. The moisture content in the cobs was 24 %. The evaluation was based on the following parameters: efficiency of the husking process, % - consumed energy, kw h-1 – specific consumed energy, kw /kg h-1– machine productivity, kgh-1 – operation and manufacturing costs, L.E. To improve machines performance ( productivity and efficiency ) , adjustment was made by narrowing the distance between the protrusions of the husking cylinder from 5 mm to 2.5 mm and increasing the length of the husking cylinder from 100 cm to 200 cm led to increase in the distance traveled by the corn cob over the active part of the machine and thus the increase in the time during , which the cob remains in contact with the surface of the active part. | ||||
