Superheated Steam Continuous Sterilizing System Exclusive for Granules


Sterilizing System Exclusive for Granules

This model is dedicated exclusively to granules by its compact, low-priced and easy-maintenance design, featured by the high-pressure rotary valve. The material is distributed in a small amount to be sterilized as if it were treated with a "continuous rotary autoclave." This model incorporates the vibrating dryer cooler suited to dry and cool the granules.


  • Minimal System Configuration

    The key component is the specially-designed rotary valve only to ensure the compact and economical design and easy maintenance.

  • Excellent Sterilization Effect

    Superheated steam with big thermal energy is directly blown into the pockets of the rotary valve to kill E coli, viable cells and thermoduric cells for three to ten seconds.

  • Flexible and User-friendly Operation

    The changeable pressure, temperature and heating time make the system flexible for linds of granules.

  • Easy Cleaning

    The pneumatic pipe can be cleaned easily by flushing water from the material feeder and dried with the inline heater.
