The working process is like:
1. Raising temperature process:
Steam heat up water, and then spray the hot water to the products. until the central temperature of the products up to the required temperature ( for example: 121℃)
2. Holding temperature process:
Hold the 121℃ for a certain time.
3. Cooling process :
Cooling process is cooled by heat exchanger, the cold water did not directly go inside of the retort machine , just circulate outside , it will go through the cooling tower --- cooling water tank , then pump in the tube heat exchanger, to make inside small amount of water gradually become warm- cold-colder and until up to normal temperature.
