What’s the principle of rice milling ? The process of removing the skin of brown rice and making it into white rice that meets the requirements of eating is called milling rice, and the machinery used is called rice milling machine, or rice machine for short.Rice milling is the most important process of rice processing, because it is a direct grinding of rice grains, such as improper operation, excessive grinding, will produce a large number of broken rice, affecting rice yield and yield;Insufficient grinding, and will cause rough white uneven phenomenon, thus affecting the quality of finished products.
Therefore, the effect of rice milling technology is good or bad, directly affect the economic benefit of the whole rice mill.Rice milling should be done: on the premise of ensuring the accuracy level of finished products, improve product purity, improve rice yield, improve output, reduce costs, and ensure safe production.Mechanical rice milling can be divided into wipe off grinding white, grinding white and mixed grinding white .By the strong friction between rice grains and rice grains and between rice grains and components in the milling room of rice machine, the brown rice cortex slips along the endosperm surface, and is stretched and broken, so as to remove the sugar rice cortex.
Generally speaking, this method is not suitable for grinding indica rice with dry and hard cortex, brittle grains and poor strength due to the large pressure of rice grains in the milling room, which is easy to produce broken rice in the milling process.Wipe off the grinding white grinding products, smooth surface, bright color.Grinding grinding white is with the help of high-speed rotation of the emery roller surface countless hard, small, sharp sand, the rice skin layer is constantly grinding, so that the rice cortex broken, peeling, so as to grind brown rice white.
