Description

Rice seed impurity rapid screening device and screening method

Technical Field

The invention relates to the technical field of seed screening, in particular to a device and a method for quickly screening impurities of rice seeds.

Background

Rice is a cereal crop of the genus Oryza, and the representative species is rice. The rice is native to China and India, and the rice is planted by precedents in Yangtze river basin of China seven thousand years ago. The rice is classified into indica rice and japonica rice, early rice and middle and late rice, glutinous rice and non-glutinous rice according to the rice type. The conventional rice and hybrid rice are classified according to the seed reserving mode. Other classifications, including paddy rice and floating rice, are made according to whether soilless culture is performed; dividing season rice and 'lazy rice' (overyear ratoon rice) according to the survival cycle; the rice is divided into common rice and giant rice of about two meters according to the height; the method is divided into ordinary fresh rice and 'seawater rice' (actually, the rice mainly uses fresh water) according to saline-alkali tolerance.

The rice is obtained by removing glume from rice, weighing brown rice, and grinding rice bran layer to obtain the final product. Approximately half of the world population uses rice as staple food. Besides being edible, the rice can also be used as industrial raw materials for brewing wine and making sugar, and the rice hulls and rice straws can be used as livestock feed.

The rice need carry out the edulcoration after receiving into, current edulcoration device lacks the function of distinguishing different impurity in the rice, thereby it abandons the waste to cause easily recoverable if blighted grain etc. mixes with grit and earth, and current edulcoration device uses the limitation great, cause the pollution of indoor environment easily when indoor use, the fibre in the rice wafts into in the air or glues and arouse staff's health discomfort easily on skin, current edulcoration device efficiency is slower, and the inconvenient material of throwing of higher edulcoration device.
