Reason one: the amount of suction The Rice Polisher(LIANGGONG) https://www.china-zjlg.com/product/polishing-machine/ equipment for axial water spray should adopt the strong pull suction form. The strong pull suction can make the water entering the hollow shaft rapidly atomize under the strong negative pressure, thereby improving the uniformity of the water. However, if the amount of suction is too large, the polishing pressure of the rice will be increased, and the broken rice will be increased. Therefore, according to the specific model to choose the appropriate amount of suction, in order to effectively reduce the crushing, is conducive to the role of polishing. Reason two: line speed: The line speed of the rice polisher equipment is low, the speed of the rice leaves the iron roller is low, the collision movement is moderated, and the grinding is less after the polishing, but the rotation speed is too low, and when the rice grains are not enough, the rice grains are partially crushed too much, resulting in over-grinding. Phenomenon, over-milling will reduce the rice yield, and will also cause the rice to be partially crushed insufficiently, unevenly polished; the line speed is high, the speed and collision force of the rice grains are large, the chance of rolling the rice grains is increased, and the polishing is uniform, but when the rice rolls over excessively, It will cause the ends of the rice to be crushed, and the broken rice will increase, which will also lower the rice yield. Therefore, choosing a reasonable rotation speed to obtain a suitable polishing roller line speed is very important for reducing the broken rice rate and improving the polishing brightness of the rice. Generally, the polishing roller line speed should be 6-7 m/s. Click Rice Whitener https://www.china-zjlg.com/product/rice-whitener-machine/ to learn about more information.
