Air-jet rice milling roller for unhusked long-grain rice

Abstract

The invention provides an air-jet rice milling roller for unhusked long-grain rice. The air-jet rice milling roller comprises a rice milling roller body and a flange, wherein the front end of the ricemilling roller body is a spiral feeding section; a milling rib is connected with the spiral feeding section; a polishing block is arranged at the tail end of the rice milling roller body; a hollow cavity is arranged in the rice milling roller body; an air inlet is arranged at the front end of the rice milling roller body and communicates with the hollow cavity; an air blowing opening is arrangedat the position of the milling rib and communicates with the hollow cavity; the tail end of the rice milling roller body is a cylindrical frustum; the polishing block is arranged on the conical surface of the cylindrical frustum and protrudes out of the surface of the conical surface of the cylindrical frustum; the flange is provided with a conical hole matched with the column frustum of the tailend of the rice milling roller body; after the flange is fixed, the conical hole matched with the column frustum of the tail end of the rice milling roller body forms a polishing chamber with the column frustum located at the tail end of the rice milling roller body; unhusked rice is conveyed into a whitening chamber through the spiral feeding section; and during milling processing, a fan continuously blows air through the air inlet and the air blowing opening, so rice bran is blown away, and the temperature of the rice can be effectively reduced at the same time.

Description

technical field [0001] The invention relates to the technical field of rice processing, in particular to an air-jet rice milling drum for long-grain rice. Background technique [0002] Northeast long-grain rice is slender or long-elliptical, the length of the elder is more than 7mm, and the cross-section is oblate. [0003] The structure of the conventional rice milling drum is simple, and the rate of broken rice is high when grinding the long-grain rice in the northeast, which leads to a significant decrease in the yield of finished products, and problems such as inspection of finished products, which cannot meet the requirements of the national standard GB / T1354-2009 "Rice". At the same time, the temperature of rice rises sharply during grinding, which affects the quality of finished rice. This invention mainly solves the problems of high broken rice rate, low rice output rate and difference in finished products when the fresh rice machine grinds long-grain rice in Northe...
