Constant-temperature micro-refrigeration system of roller type germ-remaining rice mill

Abstract

The invention relates to the technical field of processing treatment of the rice industry, in particular to a constant-temperature micro-refrigeration system of a roller type germ-remaining rice mill.The system comprises an integrated air cooler, wherein a compressor is connected with a pressure-saving valve, the flow of cold air blown out by the compressor is controlled through the pressure-saving valve, the pressure-saving valve is connected with a cold pool through a pipeline, and the cold air in the cold pool enters a piston pump through a pressure release valve; air pressure generated bythe piston pump conveys cold air to different areas in a rice milling chamber of the emery roll type germ-remaining rice mill through an air hose and an air valve; a temperature sensor is arranged inthe rice milling chamber and sends collected temperature to a control device; and the control device controls the opening angle of the pressure-saving valve according to the obtained temperature value. According to the constant-temperature micro-refrigeration system of the roller type germ-remaining rice mill, constant-temperature micro-refrigeration treatment is conducted on the rice milling chamber, the germ-remaining rate can be effectively increased, meanwhile, it can be effectively guaranteed that freshness of germs and active substances of the germs are not damaged, and the quality of germ-remaining rice is improved to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of rice industry processing, in particular to a constant-temperature micro-refrigeration system of a roller-type rice mill with embryo retention. Background technique [0002] There is a lot of knowledge about the rice we eat every day. The nutrition of a grain of rice is concentrated in a small yellow spot, which is the small yellow spot that breeds life. The so-called "bud" is the part that gives birth to new life, called the germ. The weight of the germ only accounts for about 3% of a grain of rice, but it contains 66% of the nutrition of the whole grain of rice. It contains protein, unsaturated fatty acids, B vitamins, vitamin E, zinc and other essential nutrients for 90% of the human body, and is known as the "source of nutrition given by God". [0003] The roller-type rice milling machine that leaves embryo on the market all does not have constant temperature micro-refrigeration system device. Durin...

AI Technical Summary

Problems solved by technology

[0005] The present invention provides a constant temperature and micro-refrigeration system for a roller-type rice mill with germ remaining, to overcome the large amount of heat generated in the rice milling room in the prior art, which causes the water in the germ rice to evaporate and the retained "germ" to be dried invisibly , and cause the "germ" to fall off, resulting in the loss of nutrient components of the remaining germ rice, thereby affecting the quality of the remaining germ rice
