Food pulverizer machine is mainly suitable for Chinese medicinal materials, biomedicine, food spices, pharmaceuticals, foodstuff, chemicals and etc. polymer materials and other elastomers, sugary and oily high fiber materials and other materials. Using -196° liquid nitrogen as the cooling medium, the material is crushed near the embrittlement point temperature, which can crush high molecular elastomers, oily and sugary high fibers and other materials. The low-temperature environment can keep the material characteristics unchanged. Frequency conversion control, simple operation, low energy consumption, high efficiency, advanced nitrogen circuit system to ensure low consumption and environmental protection.
