Description

Rice milling machine {RICE MILLING MACHINE}

The present invention relates to a rice milling apparatus, and more particularly, to a rice milling apparatus capable of smoothly grinding the surface of rice.

In general, a milling machine is a machine that peels off the bran layer attached to the rice. Grinding-type rice-cleaning machines and friction-type rice-cleaning machines are mainly used.

The surface of the grain is sharpened by the blade of the kumgang thread that is rotated when the apex grinder coated with a silicon carbide material on the outer circumference of the grinding-type milling machine is rotated, and the friction type milling machine is rubbed as the grain passes between the roller and the screen. Each of them performs a polishing action in which the epidermis is peeled off.

The friction type mill provides a flow of air with a constant pressure generated by the blower to the pressure feeding path of the grain being fed, cooling the frictional heat generated between grains, and at the same time removing the grain dust generated in the grinding process. It has a discharge function that pushes it out of the screen.

In the prior art, since the grinding-type rice mill is polished using a silicon carbide tip grinder, it can easily damage the surface of the rice and cut it down, so the frictional heat can be lowered. It has a drawback that leads to deterioration.

In addition, the friction-type milling machine strongly rubs rice and rice with each other, so that the epidermis, pericarp, seed skin, algal layer, and subhomogeneous layer are removed by using the frictional force acting on each other, so high pressure is required during grinding. And, since grinding is performed only when the coefficient of friction is high, it inevitably increases the temperature of the grain to reduce the quality. Therefore, there is a need to improve this.

The background technology of the present invention is disclosed in Korean Patent Laid-Open Publication No. 10-2019-0116633 (published on October 15, 2019, title of the invention: a milling machine with improved grain peeling structure).
