Product Description

A water immersion sterilizer retort is a pressure chamber used to carry out industrial processes requiring elevated temperature and pressure different to ambient air pressure. Autoclaves are used in food factory to eliminate the harmful bacteria in canned food, mushroom glass jar, egg vacuum packing, vacuum packed rice, and fish tin can. In medical applications autoclaves are used to perform sterilization; and in the chemical industry to cure coatings, vulcanize rubber and for hydrothermal synthesis.
Many autoclaves are used to sterilize equipment and supplies by subjecting them to high pressure saturated steam at 121 °C (249°F) for around 15-20 minutes depending on the size of the load and the contents.  But in some start-up business firms and Laboratory for big food factory, electric heating type autoclave are widely used.
Electric Heating Water immersion sterilizer retort (back pressure sterilization equipment)

Electric heating water immersion sterilizer retort that we can offer have different configuration, for example, the layout of the water immersion sterilizer retort vessel may different a lot. Most of our water immersion sterilizer retort are designed according buyers request. Here now we list our some commonly used layout of high pressure water immersion sterilizer retort for your reference:

1. Series No. R-S (horizontal water immersion sterilizer retort with single sterilization vessel)

This series have 2 hot sell water immersion sterilizer retorts, we give them different Reference No. to distinguish them:

• Ref. No. S E S.

Single vessel water immersion sterilizer retort with electric heating and water sprayer.
Here the first "S" means the water immersion sterilizer retort vessel is single---single vessel and single wall, no thermal insulation material used. "E" stands for the heating mode of this water immersion sterilizer retort is electric. At the bottom of the water immersion sterilizer retort, there will be 2 or 3 electric heating tubes. The last letter "S" tells about the way of heat transfer in the water immersion sterilizer retort. When this water immersion sterilizer retort working, the steam jet and / or water droplets will spray out towards the content in the sterilization chamber to generate an evenly heating.

• Ref. No. S V S.

While the above mentioned water immersion sterilizer retort use steam heating rather than electric, we change the middle letter "E" in the Ref. No. resulting a new water immersion sterilizer retort which is heated by steam vapor, single sterilization vessel with sprayer.
 

1. Series No. R-I (Horizontal water immersion sterilizer retort with insulated sterilization vessel)

This series have 3 hot sell water immersion sterilizer retorts, here we list the reference No. for your reference.

• Ref. No. E S

This ref. No. stands for an insulated water immersion sterilizer retort heated by electric, with steam sprayer. Steam or hot water usually spray out from the top of the inner water immersion sterilizer retort chamber. Under request, we can made it into top and side spray type.

• Ref. No. T S  

This ref. No. shows us the water immersion sterilizer retort is electric heating type with sprayer. Compared with the water immersion sterilizer retort mentioned above, this water immersion sterilizer retort have an insulated water storage tank besides the sterilization pot. This sterilization structure is commonly used in factories which have limited height for the water immersion sterilizer retort.

• Ref. No. O S

This reference No. will introduce a hot sell water immersion sterilizer retort to us --- the overlay type water immersion sterilizer retort. The sterilization vessel was heated by electric, with steam / hot water sprayer, with insulated sterilization pot. What's more, it comes with high level water tank on the sterilization pot. That means the water recycle tank was fixed on the top of the sterilization vessel. It is one on another instead of one beside another.  
All the above listed water immersion sterilizer retorts are water spray type. Water immersion type water immersion sterilizer retort and water circulation type water immersion sterilizer retort are also in our business scope. No mater you need water spray water immersion sterilizer retort, water immersion water immersion sterilizer retort or water circulation water immersion sterilizer retort, the heating medium can be all saturated steam at 121 °C. all of them use counter pressure to protect your product from got broken due to the pressure in the sterilization process.
 


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

Water immersion sterilizer retort working flow
Steam spray water immersion sterilizer retort / steam heating water immersion sterilizer retort 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 water immersion sterilizer retort chamber for a rapid cooling. After the cooling process, we finished the sterilization batch. So, a steam heating / steam spray water immersion sterilizer retort 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 water immersion sterilizer retort chamber and seal the door.
• Pump process water into the water immersion 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 cooling
• Unloading the tin can / glass jar / bottle and finish the sterilization batch

Explain of steam spray retort water immersion sterilizer retort / water immersion sterilizer retort retort / sterilization retort
When steam spray water immersion 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 / water immersion sterilizer retort / retort water immersion sterilizer retort. 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 water immersion sterilizer retort retort
During the preheating process, counter pressure will be unnecessary. After the content in water immersion sterilizer retort 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 water immersion sterilizer retort body to the hot water or cold water storage tank.
Benefits of water spray water immersion sterilizer retort
