Abstract
Rice washing machine is a kind of food processing machinery, for the rice washing device. The design of the spiral rice washing machine is composed of motor, horizontal spiral shaft, inclined screw shaft and corresponding reducer, a frame structure. Metres from the inlet into the washing machine, the spiral shaft carried by the conveyor to rubbing washing, water flow and countercurrent flow meters flow, Minaka floating impurities in the process of floating, and washing muddy water from overflow outlet, reach the rice washing purpose. It has the advantages of simple structure, small occupation area, rice, rice washing, rubbing the set of removing floating impurities, such as gravel as one with less water, good washing effect, is a kind of high efficient continuous washing rice machine, is the cafeteria, hotel, large fast food centers relatively ideal grain lavation machinery.
The design of formulation of the rice washing machine the overall structure scheme, the movement and power parameters; completed the horizontal spiral shaft, inclined screw shaft and corresponding reducer, rack structure design
