AI Overview
A liquid nitrogen (
) pulverizer, or cryogenic pulverizer, is an industrial machine that uses extremely cold liquid nitrogen (approx.
) to brittle materials before grinding them into fine powders. It is primarily used for substances that are heat-sensitive, soft, sticky, or elastic at room temperature (e.g., plastics, spices, pharmaceuticals, rubber).
Key Features and Benefits
- Embrittlement: Freezes materials to make them brittle and easy to pulverize.
- High Quality: Prevents thermal degradation, preserving aroma and color in food products.
- Fine Particle Size: Capable of achieving ultra-fine mesh sizes.
- Efficiency: High-speed grinding with lower energy consumption compared to ambient methods.
Applications
- Food Processing: Spices, herbs, oily materials (cumin, chili), candy.
- Pharmaceuticals: Active ingredients, herbs, resins.
- Recycling & Chemical: Plastics (PVC, PE, PP), rubber, tires.
Typical Components
- Feeding System: Screw feeder to introduce raw material.
- Grinding Chamber: Where is injected and the material is crushed.
- Pulverizer Mechanism: Hammer, blade, or disk mill.
- Cyclone Separator: To separate the final powder product.
- Blower/Control System: Controls air flow and cooling.
If you are looking to purchase one, industrial models range from smaller pilot systems to large-scale, high-capacity industrial units, often sourced from specialized manufacturers like Sevenstars or WANROOETECH.
