Abstract

The invention relates to a novel cryogenic grinding machine and a working mode thereof. According to the novel cryogenic grinding machine, pre-cooling equipment for materials is arranged in front of agrinding stock bin, a two-stage semi-closed piston type refrigeration compressor and a R507A refrigeration compressing agent are used on a heat exchanger, the cooled air is introduced into a coolingstock bin in a circulation mode to enable the materials to be cooled to minus 40 DEG C, and the materials are pre-cooled; and the materials are brittle at a low temperature, the materials are easier to grind, liquid nitrogen introduced into the cryogenic grinding machine can rapidly diffuse and absorb the heat of gas, the temperature of the circulating gas is gradually decreased to reach a set temperature, the liquid nitrogen is rapidly diffused in the cryogenic grinding machine, the volume of gas in a circulating air pipe is increased, the increased gas is discharged through an auxiliary airchannel, the cryogenic grinding machine can reduce the amount of the liquid nitrogen, the grinding efficiency is improved, and the use cost of the novel cryogenic grinding machine is reduced.

Description

technical field [0001] The invention relates to a new type of frozen pulverizer and its working method. Background technique [0002] When crushing Chinese and Western medicine products, food, seasonings, and chemical raw materials, a pulverizer is needed to pulverize the materials. At present, there is only one kind of pulverizer that uses liquid nitrogen freezing to pulverize the materials. This pulverizer using liquid nitrogen freezing needs to directly cool down the normal temperature material through liquid nitrogen before it can be pulverized, resulting in a large amount of liquid nitrogen usage, high pulverization cost, low efficiency, and is not easy to popularize. Contents of the invention [0003] The object of the present invention is to overcome above-mentioned deficiency, provide a kind of reducing liquid nitrogen dosage, improve pulverization effect, reduce cost a kind of novel frozen pulverizer and its working mode. [0004] The purpose of the present inven...
