Requirements of maize mechanical shelling.

In order to optimize the maize productivity and quality, various aspects of production chains should be considered in an integrated way, including crucial steps to improve and conserve the maize crop. The lack of sufficient quantity of quality maize grains was sheller methods, clearances between cylinder, and maize grains moisture content is a major bottleneck to improve maize productivity and quality in Factory. This study is aimed to identify the effect of local thresher machine on maize cultivar Rabie based on some technical indicators, under two clearance of threshing cylinders (0.7 and 0.9mm) and three maize grain moisture content. The experiments were conducted in a factorial experiment under complete randomized design with three replications. The 0.9mm clearance was significantly better than 0.7mm clearance while the maize grains moisture content at range of 13%-15% was significantly superior to other ranges of 15%-17% and17%-19% in all studied parameters. For local THM the machine productivity, power consumption, threshing efficiency, grains damage, broken corn, grain cleaning, were 1.251 th-1, 9.358 kW, 88.717; 1.529; 3.272; and 1.318 percent respectively. The interaction among maize grains moisture content of 13%-15% and the clearance between cylinder 0.9mm gave the best result in all studied parameters. [ABSTRACT FROM AUTHOR]
