Design and Build of Popped Rice Separate Machine

Abstract

The lot of big popped rice is ingredient in Kayasart which sort by separator that consist of 3 layers’ sieve dimension 600 mm x 1600 mm x 530 mm. The first layer is 6 mm of hole circle sieve which can move the big popped rice on the surface to exit channel but the thing less than 6 mm will though on the second
layer that has 5 mm of hole circle sieve. The small popped rice and dust are separated pass to on the last layer.to on the last layer. The sieve set are fixed on the frame's dimension 1000 mm x 1600 mm x 1000 mm by belt that can transmission power by motor of 746 W. The variables of this study are sieve speeds; 5.80 m/s 6.08 m/s and 6.83 m/s, and the sieve inclines; 7 deg, 25 deg and 30 deg. It was found that, the variables are 6.83 m/s of sieve speed and incline of the sieve is 30 deg, which have popped proportions on the first layer, the second layer, impurities and loss amount around 92%, 3.52% 4.65% and 0.33%, respectively. In addition, the separation capacity of these variables is lower than other tests around 126 kg/hr but it has high efficiency is 65.09%.
