KPU
Classification
- Sterilization
- Food and Beverage
- Pharma and Nutraceutical
Various kinds of powder, cut materials and granules are sterilized continuously and instantly (four to five seconds), using superheated steam.
Features
- Excellent Sterilizing Effect
Superheated steam with big thermal energy kills E coli, viable cells and thermoduric cells instantly. - Minimal Product Deterioration
Short heating time, anaerobic atmosphere and constant temperature in the pneumatic pipes minimizes the product deterioration such as loss of active ingredients or oxidation. - Flexible User-friendly System
The changeable pressure and temperature make the system flexible for kinds of powder and granules. - Easy Cleaning
The pipe interior can be cleaned by flushing water from the material inlet, and dried with the inline heater. - Energy-saving
The recycling of superheated steam saves energy to increase the thermal efficiency.
Typical Applications
Spices / Herbal / Medicines / Health foods / Cereals / Fish powders / Dry vegetables / Tea leaves, etc.
