A kind of multi-layer rice rubbing machine

Abstract

The invention discloses a multilayer germ-left rice milling machine, relates to a rice milling machine, in particular to the multilayer germ-left rice milling machine, and solves the problems of requiring a plurality of devices to mill a plurality of times to obtain qualified finished rice because the existing germ-left rice milling machines all adopt single-layer structures, having lower milling efficiency, and needing secondary screening as impurities generated in the milling process cannot be discharged. The multilayer germ-left rice milling machine comprises a rack, an impurity pool, a plurality of rice milling mechanisms, a plurality of negative pressure air pipes, a plurality of impurity discharging guide pipes, a plurality of impurity discharging hoppers and a plurality of driving motors, wherein the plurality of rice milling mechanisms are mounted on the rack from the top down in sequence, a negative pressure air pipe is arranged in an outlet hopper of each rice milling mechanism, the impurity discharging hoppers are arranged below screens at the lower parts of the outlet hoppers of the rice milling mechanisms, each impurity discharging hopper is communicated with the impurity pool through an impurity discharging guide pipe, the plurality of driving motors are mounted at the bottom of the rack, and each driving motor drives one rice milling mechanism. The multilayer germ-left rice milling machine belongs to the field of agricultural machinery.

Description

technical field [0001] The invention relates to a rice rubbing machine, in particular to a multi-layer rice rubbing machine with embryos left, belonging to the field of agricultural machinery. Background technique [0002] Rice is the finished product of paddy after cleaning, husking, rice milling, finishing and other processes. Rice contains about 75% of carbohydrates, about 7% to 8% of protein, 1.3% to 1.8% of fat, and is rich in B vitamins, etc. Therefore, eating rice has high nutritional value. Germ rice is a kind of rice that retains the germ part of rice, and the other parts are exactly the same as white rice. The most important central part of rice is the germ. As the name suggests, the so-called "bud" is the part that gives birth to new life. Its scientific standard name should be called "grain rice", which is rice with a germ retention rate of more than 80%. The existing germ rice mills all adopt a single-layer structure, and the rice milling efficiency is low, a...
