Super Heated Water Spray Type Sterlizer

 

Super Heated Water Spray Type Sterilizer Super heated water spray type sterilizer is used to sterilize the end products in the sealed containers. The Super heat water spray sterilizer is widely used in the pharmaceutical industry for the sterilization. The process is also known as terminal sterilization. Super heated type water spray sterilization machine is used to perform terminal sterilization of product in a deformable and non deformable container. The sterilization is done under differential pressure and heat exposure using a hot water spray. The super heat water spray sterilizer is used to sterilize bottles, pouches, glass bottles and plastic bags.

Process of operation

The product is introduced into the sterilizer chamber using carriages and trays. Purified water is introduced into the chamber bottom and is circulated by a centrifugal pump in a closed loop. The water is made to pass through an external heat exchanger to attain the required temperature for sterilization. The heated water is passed through a distribution plate in the from the top of the chamber. The increased rate of flow of water helps it to attain the sterilization temperature in minimum time. A counter pressure is applied by the sterile filtered air to prevent the rubber closures from being displaced from the glass bottles. The water is made to cool by an external heat exchanger after sterilization. The cooled water continues to circulate for the cooling of load in the chamber. The whole sterilization process is completed in one hour.
