Design and evaluation of a cleaning machine
Journal Title: Applied Science Reports - Year 2013, Vol 1, Issue 3
Abstract
A device for cleaning threshed seeds was been developed. The cleaning system consists of an air – blast fan and a reciprocating shaker containing replaceable sieve for different crop seeds and a collecting pan. The performance of the prototype was evaluated in terms of percentage cleaning efficiency and grain loss at various levels of feed rates, and fan speeds. The test crops used were sorghum, soybean and millet. The best performance was obtained at cleaning efficiencies of 95, 98 and 91% and percentage grain losses of 0.63, 0.81 and 0.75% respectively for sorghum soybean and millet. The optimum values of feed rates were 4, 2.5 and 3.5 kg/s while these of fan speeds were 415, 505 and 582 rpm for the respective crops.
