Rice grain cutting device and processing machine using same and capable of completely keeping rice germs

Abstract

The invention discloses a rice grain cutting device and a processing machine using the same and capable of completely keeping rice germs and relates to rice grain cutting devices and equipment. The rice germs and the rice grains are separated through cutting to overcome the defect of germ loss during coarse rice layer polishing. The rice grain cutting device is characterized in that a constant ratio transmission mechanism drives a rice pressing wheel to rotate relative to a sheave, wheel teeth are inserted into rice grooves, the tops of the wheel teeth are pressed onto the rice grains, and thewheel teeth elastically shrink in the height direction to reveal the rice cutters on two sides so as to cut the two tips of the rice grains to separate the rice tips containing the germs from the middle sections of the rice grains. The processing machine comprises a shell, a hopper, a rice polisher, a rice grain alignment device, the rice grain cutting device and a rice tip collecting retaining plate and is characterized in that the hopper is arranged at the top in the shell, the inlet of the hopper is communicated with the outside, the lower outlet of the hopper is communicated with the inlet of the rice grain alignment device, the rice grain alignment device is obliquely arranged, the outlet of the rice grain alignment device extends towards the rice grain cutting device, the rice cutting device is mounted in the middle in the shell, and the rice polisher 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
