Ventilator Steam sterilizer


ventilator steam sterilizer A ventilator steam sterilizer is an effective method of terminal sterilization of vials, ampoules, contact lenses and solutions in open or semi closed containers. The ventilator type steam sterilizer leaves the product completely dry after the process of sterilization. The ventilator steam sterilization machine is widely used to sterilize large volume infusion in in plastic bottles & plastic bags.

Process of operation

The load is fed into the chamber using carriages and trays. The steam is introduced into the chamber by a perforated conduit at the top of the container. Blower fans are installed on the sealing of chamber. The number of fans depend on the depth of the chamber. The homogenization of air with steam and circulation of steam is supported by the blower fans. A uniform heating of load is attained by the system. The filtered air is introduced into the chamber in order to attain a counter balance of pressure. The product is made to pass through a colling phase after the sterilization. The cold water carried by the finned tube heat exchangers decreases the temperature of the product. The sterilized end product comes out cool and dry. The salient features of steam sterilizer ventilator type machine are mentioned below:

Salient features:
  • Finned tube heat exchangers for cooling
  • Guide rails for easy movement of product
