KPU

Classification
  • Sterilization
 / Business line
  • Food and Beverage
  • Pharma and Nutraceutical
"KPU" is a system designed to use superheated steam to continuously, naturally and instantaneously (4 to 5 seconds) sterilize a wide range of powder, shredded or grain materials.

Features

  • Excellent Sterilization Effect
    Superheated steam provides high thermal energy, capable of disinfecting both general cells and hermoduric cells instantaneously and naturally.
  • Minimal Product Deterioration
    Short heating time, anaerobic atmosphere and constant temperature in the airflow pipes minimize the risk of product deterioration such as loss of active ingredients or oxidation.
  • Wide working range and easy to use
    Pressure and temperature conditions can be set as desired, allowing an extensive range of operation, and making KPU suitable for sterilization of a wide variety of powders and grain materials.
  • Easy Cleaning
    The pipe interior can be cleaned by flushing water from the material inlet, and dried with the inline heater.
  • Energy-saving
    Superheated steam is recycled through circulation, making it a highly energy-efficient device.

EXAMPLE OF APPLICATIONS

Spices/herbs/health foods/cereals/fish meal/tea leaves/etc.

※Capacities are based on powders with a bulk density of 0.5kg/L and may change depending on material properties.may change depending on material properties
※Steam consumption depends on the material being processed as well as operation conditions.
※Steam consumption value is for stable operation. In equipment startup and cleaning, approx. 5X of steam may be required.
※Cleaning water is needed (equipment cleaning process).
