Main description:
The cryogenic grinding machine is consist of stock bin, grinding machine, induced draft fan, cyclone, vibrating scteen, liquid nitrogen container(provide by yourself). The lowest temperature of liquid nitrogen can be reach to -196 degree, according to different material brittle temperature, the temperature can be adjust during the grinding process. The fineness of final material can reach to 10-1000 mesh, even to μ M, meanwhile, for different fineness requirement, the fineness can be different by adjusting the devices.
Using liquid nitrogen as grinding medium, it can avoid the material's metamorphic caused by heating during crushing, thus, it can keep material's color, taste, flavor and nutrition. This machine can be widely used in foodstuff industry, such as chilli, pepper, ginger, potato, corn, rice, wheat, astragali, ginseng, herbs, ect.
Main Principle
This machine uses liquid nitrogen as cold source, the raw material will be crused by the blades' impaction, friction and collision after it is precooled into embrittlement state. The well crushed material will be sorted and collected by the air flow sieving machine, the not crushed material will go back to stock bin for second time grinding. During the process, the liquid nitrogen forms a closed cycle system, in which the liquid nitrogen will return the stock bin for cycle use.
Main Features
This machine is with high performance liquid nitrogen device, can collect the liquid nitrogen with back flow method after heat exchangement with raw material during gasification process. With pipes and valves can adjust the cycled liquid nitrogen, which can guarantee the air flow in crushing charmber. Thus, raw material's precooling, closing delivery, closing sorting, discharging, air cycling, liquid nitrogen usage rate, thermal insulation, ect, reaching to maximum impact.
