KPU

Classification
  • Sterilization
 / Business line
  • 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.
