KPU
Classification
- Sterilization
- 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.
