Autoclave steam sterilizer is a kind of hermetically sealed and pressurized heater, and used for sterilizing the food sealed in a container. Autoclave steam sterilizer is consisted of boiler body, cover, open-initiate system, locking wedge, safety interlock device, pathway, sterilization basket, and steam nozzle, etc. It is mainly used for food industry and pharmaceuticals industry, etc.

The autoclave steam sterilizer could be applied to a variety of high temperature packaging materials

1. Plastic & rubber container: PP bottle, HDPE bottle, PP can, HDPE can 
2. Flexible package: aluminum foil bag, transparent bag, vacuum bag, retort pouch 
3. Glass container: Glass bottle , glass jar 
4. Metal can: tin can, aluminum foil can 


Advantages

1. Multi-stage temperature, sterilize thoroughly

The sterilizer use high efficiency heat exchanger, the temperature rise up quickly, save energy. Set up different temperature based on different products, to make sure the taste, color, and nutrition are not be damaged.

2. Uniform temperature distribution
Set up pulse spraying device, hot water is sprayed in wave shape. There are several sprayer at each layer, to make sure the uniform temperature within the sterilizer.

3. Indirect heating, prevent secondary pollution
The circulation water is sent to heat exchanger by circulation pump for heating, the container will not contact with steam or water, prevent secondary pollution.

4. High quality sealing and material
The cover is sealed by inflatable silicon rubber sealing ring, reliable sealing, and long working life. The internal boiler body is made of stainless steel, acid-proof and heat-proof.

5. PLC automatic control
Adopts PLC automatic controller, could automatic adjust the temperature and pressure, operate automatically and conveniently.

6. Equipment customization
Sitong boiler could manufacture the specific products according to different customers’ requirements. 



Working principle

1. Water filing
Prior to the start of the process, the retort is filled with a small volume of process water such that the water level is below the bottom of the baskets. This water can be used for successive cycles if desired, as it is sterilizec with each cycle.  
2. Heating 
Once the cycle is begins, the steam valve opens and the circulation pump is switched on. The mixture of steam and water spraying from top of the retort vessel creats highly turbulent convection currents that rapidly homogenizes the temperature at every point in the retort and between the containers.  
3. Sterilization 
Once the programmed sterilization temperature has been reched, it is held for the programmed time with +/-1 °F . Similarly, the pressure is kept with +/- 1 psi by adding and venting compresed air as needed.  
4. Cooling 
At the end of the sterilization step, the retort switches into cooling mode. As the process water continues to be circulated through the system, a portion of it is diverted through on side of a plate heat exchanger. At the same time, cold water passes through the other side of plate heat exchanger. This results in the process water inside the retort chamber being cooled in a controlled fashion.  
5. End of cycle 
Once the retort is cooled to the programmed temperature setpoint, the cold water inlet valve on the heat exchanger closed and the pressure inside thr retort is autoamtically relieved. The water level is lowered from the maximun down to the medium level. The door is equipped with a safety locking device which prevents the oping of the door in the case of residual pressure or high water level.  retort pouch sterilizerwater bath sterilizer retort water immersion retort autoclave
