Rice Grain Shearing Device and Its Processing Machine for Retaining Whole Rice Germ

Abstract

A rice grain shearing device and a processing machine using the same for leaving whole rice germ. The invention relates to a rice grain shearing device and equipment. It uses a cutting method to separate the germ from the rice grains to solve the defect of losing the germ when grinding the brown rice layer. The fixed-ratio transmission mechanism drives the rice pressing wheel to roll against the grooved wheel. The gear teeth are inserted into the rice groove, and the top of the gear teeth is pressed on the rice grains. The teeth shrink elastically in the height direction, so that the rice cutters on both sides are prominent, The guillotine is cut on the two tips of the rice grain, thereby separating the tip of the rice with the germ from the middle section of the rice grain. The processing machine includes a shell and a hopper, a rice grinder, a rice grain alignment device, a rice grain shearing device and a rice tip collecting baffle. At the entrance of the device, the rice grain alignment device is arranged obliquely and its outlet extends to the rice grain cutting device; the rice grain cutting device is installed in the middle of the shell; the rice grinder is arranged below the rice grain cutting device in the shell.

Description

technical field [0001] The invention relates to a rice grain shearing device, and also relates to a rice germ processing machine using the rice grain shearing device. Background technique [0002] Each rice is composed of rice bran and endosperm, and rice bran is composed of aleurone layer, germ, rice husk, pericarp, seed coat and outer billet. The rice with the husk removed is called brown rice. Most of the quality of brown rice is the endosperm. The quality of the embryo accounts for about 2% to 3.5% of the whole rice grain, but it is rich in fat, protein and vitamins, and is the place where nutrients gather. The embryo is also called the germ. If the germ can be retained to the maximum extent, the nutritional value of rice will inevitably be improved. [0003] Brown rice is time-consuming to cook due to its dense texture and has a poorer texture, so it must be ground into polished rice. When brown rice is processed into ordinary white rice, the germ will be removed. In ...

Problems solved by technology

[0005] The object of the present invention is to provide a rice grain cutting device and a processing machine using it to keep the whole rice germ. It uses a cutting method to separate the germ from the rice grain, which solves the problem of loss of the brown rice layer on the rice grain in the traditional technology. germ defect
