Germ rice milling method with high germ remaining rate

Abstract

A germ rice milling machine is used for milling rice, firstly, to-be-milled rice is put in from a feeding port, a first motor drives a first rotating shaft to rotate, the first rotating shaft drives a rotating rod to turn up the rice, a movable door is opened, the feeding port is sealed through a sealing cover, and then the rice is milled; the air blower blows air to discharge impurities in the rice to the conical cover from the impurity discharge hole; impurities in rice are removed through the air blower, a rice bran layer is secondarily removed from the rice through the gravel balls, the rice bran layer is thoroughly removed, the rice cannot be excessively extruded in the whole process, the rice milling time is prolonged through two times of rice milling, the rice damage area is reduced, the germ remaining rate is kept at 95% or above, and the rice quality is improved. And water in the annular water tank is discharged into the water cavity through the water pump, so that the spherical cover is kept in a cooling state, the low-temperature state can be kept in the rice milling process, the cold peeling effect is achieved, and nutrients of the milled rice with embryos cannot be damaged.

Description

Technical field [0001] The present invention relates to the field of food processing technology, specifically a high embryo retention rate of germ rice milling method. Background [0002] Germ is the essence of rice, is the embryo of rice, is the meristem of rice, rich in nutrients necessary for life movement, enriched with more than a dozen kinds of bioactive ingredients, is a unique natural source of nutrition, is a rare food nutrition treasure house, produced magical nutrients, rich in initial life energy, can bring great vitality to the human body. The protein and lipid content in rice germ are more than 20%, the amino acid composition in protein is relatively balanced, and the natural vitamin E in lipids is (200 ~ 300mg) / 100g, of which fatty acids are more than 70% unsaturated fatty acids, and are rich in trace elements and minerals. Because the existing mechanized rice milling method will generate heat due to friction during the rice milling process, a large amount of ri...

AI Technical Summary

Problems solved by technology

Because the existing mechanized rice milling method will generate heat due to friction during the rice milling process, a large amount of rice milling will cause the surface heat of the mechanical grinding plate to be too high, thereby causing the nutrient loss of the germ rice, and the germ rice will be under too much pressure during the rice milling process. The germ of germ rice is milled off, resulting in a reduction in the germ retention rate. Therefore, a method for milling germ rice with a high germ retention rate is proposed
