Embryo grain separating device for rice machining

Abstract

The invention discloses an embryo grain separating device for rice machining and belongs to the technical field of rice machining. The embryo grain separating device for rice machining comprises a separation box. A feeding opening, a guiding plate, an air inlet and a fan are arranged on the upper part of the separation box. The lower part of the separation box is symmetrically provided with two screening cavities. Screening mechanisms are arranged in the screening cavities. Each screening mechanism comprises a screening net. The screening nets are connected with a shaking assembly. Rice is fedinto the separation box, the rice falls along the guiding plate, the fan conducts winnowing on the falling rice, and then initial separation action is achieved; by means of rotation of a rotating motor and a rotating disk, under the action of a short shaft and a connection groove, the moving rod is made to move up and down in a reciprocating manner, so that by means of the connection groove and aconnection shaft, two rotating rods are made to simultaneously swing in a reciprocating manner, and then the screening nets in the screening cavities are driven to swing in a reciprocating manner; and in this way, screening and separation are conducted on bran and embryo grain in the two screening cavities, and then the separation effect is further improved.

Description

technical field [0001] The invention relates to the technical field of rice processing, in particular to a germ grain separation device for rice processing. Background technique [0002] Rice refers to the fruit without removing the rice husk. Botanically, it belongs to the common rice subspecies in the common cultivated rice subgenus of the genus Poaceae. Human beings have confirmed 22 types of rice, but the only one used in bulk trade is common rice. my country is one of the countries with the longest history of rice cultivation and the richest rice genetic resources. The ancient cultivated rice specimens unearthed at the Yuchanyan site in Shouyan Town, Dao County, Hunan Province proves that it is the known origin of cultivated rice in the world. [0003] The shape and structure of rice grains are mainly composed of rice husk and brown rice. The rice husk consists of four parts: glume, glume, glume, and glume. The glume is slightly longer and larger than the glume, and the ...

Problems solved by technology

[0005] Rice is a finished product made of rice after cleaning, husking, rice milling, and finished product finishing. During the rice milling process of rice processing, because there is a layer of scutellum between the embryo and endosperm, the connection between the embryo and the endosperm It is not firm, and the embryo is easily crushed from the endosperm by the rice miller to form germ grains and mixed with the bran husk. However, the existing separation device is simple in structure, usually only equipped with a screen, and the bran husk is separated by the screen. Separation from germ kernels, the separation effect is poor, it is easy to cause a certain amount of germ kernels to be mixed in the bran hulls, and be discarded together with the bran hulls, resulting in waste
