Description

Rice milling burnishing device is used in rice processing

Technical Field

The invention relates to the technical field of grain processing equipment, in particular to a rice milling and polishing device for rice processing.

Background

Rice processing refers to a process of removing rice husks (glumes) and skin layers (bran layers). Generally, harvested rice grains need to be peeled off to become rice grains, and the process is generally called rice milling in the field of agricultural production.

In vast rural areas, the traditional rice milling processing operation is to send grains to a processing point for centralized husking and then carry out air separation to remove bran so as to obtain rice. The traditional rice milling machine has the advantages of large volume, high price, large noise, more broken rice in the produced rice, poor rice quality and low rice yield. At present, the skin layer is removed by utilizing the mechanical action to the most in the mechanized rice mill of china, the skin layer is removed by the friction of rice mill and the effect such as grinding, but the rice mill is got rid of in the rice milling processing at present and is not thorough, and the rice bran dissipates easily in the processing environment, influence the respiratory tract health of producers, and simultaneously, current rice milling equipment is inside only to be equipped with a set of motor and drives a set of rice milling device operation, need reciprocal multiple operation with the polished rice that the corn becomes white, can't polish and pick out broken rice, waste time and energy, it is very troublesome, bring very big trouble for the staff, so we have proposed a rice milling burnishing device for rice processing.
