Steam-Spray-Counter Pressure Retort sterilizer
Steam Water Spray Retort
Retort sterilizer is also called sterilizer retort or sterilization retort. In some country and area, sterilizer also being referred to as autoclave or autoclave sterilizer. Clave is also being used as the name of a sterilizer retort.
We can see many different packing and package for fruit, juice, meat and fish, tin can, glass jar, PP bottle, vacuum package…most of them need to be sterilized before they are send to supermarket. A sterilizer retort is the right machine which used to sterilize the above mentioned products.

Sterilizer retort working flow
Steam spray sterilizer / steam heating sterilizer use steam jet to heat the content to about 121 degree C for 10 to 30 minutes. After cooling, cool water or ice water was introduced to the sterilizer chamber for a rapid cooling. After the cooling process, we finished the sterilization batch. So, a steam heating / steam spray sterilizer working process should be like this:
Loading glass jar / fish tin can or any other package into the autoclave basket.Push the sterilization baskets into the sterilizer retort chamber and seal the door.Pump process water into the sterilizer retort body.Turn on the steam inlet valve to start the pre-heating process.When temperature arrived to 121 degree, turn down the steam inlet valve and keep the temperature at 121 degree C without any significant increase.Add some compressed air into the retort or open the pressure relief valve to control the pressure at a suitable level.Pump cooling water to the retort chamber or plate heat exchanger (if exist) for coolingUnloading the tin can / glass jar / bottle and finish the sterilization batchExplain of steam spray retort sterilizer / sterilizer retort / sterilization retort
When steam spray sterilizer retort working, directly injected steam blends with fine droplets of the water spray and results in an extremely homogenous heat transfer environment throughout the whole autoclave / sterilizer / retort sterilizer. As water jets spray into the sterilization baskets from its top and the sides as well, even and rapid heating and cooling process will be achieved.
Counter Pressure in sterilizer retort
During the preheating process, counter pressure will be unnecessary. After the content in sterilizer being heated to 121 degree C or any other sterilization temperature, the counter pressure will be needed especially in the sterilization process of glass bottle and tin can. The counter pressure is mainly generated from the compressed air. This pressure will help to keep the bottle cap stay at the bottle without flip out due to the inner bottle pressure. That is to say, counter pressure during the sterilization process will help the autoclave users increase the sterilization efficiency.
Compressed air is also being used as a force to press out the hot water and cool water from the sterilizer body to the hot water or cold water storage tank.
Benefits of water spray sterilizer retort Quick heating in preheating processuniform heat distribution in sterilizer chamber Rapid and even cooling. Low electricity, steam and water consumption. Safe counter pressure control during all process phases.Accurate temperature controlSuitable for different types and sizes of package.
