Liquid nitrogen low-temperature crusher/grinder supports customization

The liquid nitrogen low-temperature crusher is an efficient equipment designed specifically for the crushing of special materials. Its core technology is to use -196 ℃ liquid nitrogen as an ultra-low temperature cooling medium, and achieve efficient crushing of materials by accurately controlling the material temperature to near the brittleness point. This technology breaks through the limitations of traditional crushing equipment on difficult to process materials such as polymers, oil and sugar containing materials, and high fiber materials. It can maintain the original physical properties, chemical composition, and biological activity of the materials throughout the crushing process.

The equipment adopts a full machine frequency conversion control system, which is easy to operate and has flexible parameter adjustment; The optimized nitrogen circuit system can maximize the recycling and utilization of low-temperature liquid nitrogen, significantly reducing energy consumption while improving operational efficiency. It is a modern crushing solution that balances environmental protection and efficiency.

Core technological advantages

Ultra low temperature protective crushing, low loss of ingredients

Relying on the strong low-temperature characteristics of liquid nitrogen at -196 ℃, the material is crushed in a brittle state, fundamentally avoiding problems such as coking, oxidation, and component volatilization caused by traditional high-temperature crushing. Whether it is the nutritional components in food, active substances in biomedicine, or functional ingredients in chemical materials, they can all be fully preserved to ensure stable product quality.

All stainless steel clean design, suitable for harsh scenarios

The whole machine is made of high-quality 304 stainless steel, with special mirror polishing treatment on the inner wall, which has strong acid and alkali resistance, strong oxide corrosion resistance, and can directly contact various corrosive materials. The equipment is easy to clean, with no residual dead corners, and meets the cleanliness standards of industries such as food and medicine; At the same time, the electrical system adopts explosion-proof design and can be directly used in explosion-proof workshops to meet the production needs in hazardous environments.

Wide area material compatibility, breaking through crushing limitations

For materials that are difficult to handle with traditional equipment, such as fibrous (plant fibers, synthetic fibers), high toughness (rubber, elastomers), high hardness (special plastics, minerals), and materials with a certain moisture content (fruits and vegetables, wet materials), efficient crushing can be achieved without pre-treatment, greatly simplifying the production process.

Fully enclosed work system, environmentally friendly and safe

The entire crushing process is carried out in a closed environment without dust spillage, effectively avoiding material cross contamination and the risk of operators inhaling dust, significantly improving the working environment of the workshop; At the same time, the effective ingredients in the material are not lost, improving the utilization rate of raw materials.

Flexible configuration+convenient operation and maintenance, reducing costs and increasing efficiency

Support the selection of automatic feeding devices based on production needs, reducing manual intervention and lowering labor intensity; The equipment has a compact structure and occupies only 60% of the traditional equipment, saving factory space; Low investment cost, simple operation interface, no need for complex debugging for material replacement, daily maintenance only requires basic cleaning and component inspection, significantly reducing operation and maintenance costs.
