Water Spray Retort for Canned Food

Automatic Water Spray Retort 

This kind of retort sterilizer is suitable for various of heat resistant packages and we strongly recommend you to buy this type.

Applicable Scope:

1. Glass container: glass jar, glass bottle

2. Metal container: tin can

3. Plastic container: PP bottle, HDPE bottle

4. Soft package: Aluminum foil bag, transparent bag, vacuum bag, retort pouches, doy-packs etc..

Features:

A. Suitable for all heat resistant package material including glass container;

B. Safety interlock Device for quick closure of retort, to ensure the safety of operator;

C. Quick heating, only need about six-twelve minutes to reach the sterilization temperature;

D. Uniform heat distribution, no blind angle ;

E. Adopting the multi-phase process for rising and dropping of temperature, minimize the temperature difference between the surface and center of packed food, maintain the flavor and nutrition of food. Mild heating and cooling process can protect the fragile container and glass container;

F. Direct heating by steam and indirect cooling by continually recycling the water through the plate type heat exchanger, avoiding secondary contamination to the food package;

G. Adopting soften water for sterilization to avoid pollution to the surface of package; no special requirements for cooling water which reduce the cost of sterilization;

H. Siemens PLC automatic control system and touch screen, easy to operate;

I. Pressure control system can adjust the pressure in the tank automatically and precisely in case the packages break or deformation during sterilization process;

J. Monitoring temperature ensures food safety, saves energy, reduces production time and assists in providing the best quality product.

Working principle:

First filling the retort with a small amount of process water and the water level is maintained below the basket bottom level. Then the process water is drawn from the bottom of the retort by a high capacity circulation pump and spray from nozzles located along the top and sides of the retort.

Simultaneously the steam valve opens and the steam is introduced into the retort through the steam spreader on the bottom of the retort directly heating those process water spraying from nozzles and making the temperature inside retort to reach the programmed sterilization temperature rapidly. The steam will keep the retort at high set temperature during the sterilization process. And the pressure in the retort also will be controlled by adding or venting compressed air as needed so that those sterilized containers will not deform or be damaged .

Finally the cooling water through heat exchanger will continually make those sterilization water cool down until the sterilization process is finished. This retort is equipped with safety locking device in case of  residual pressure or high water level.

Delivery:

We will deliver your goods by LCL/20'FCL/40'FCL depending on your order.

When loading, our workers will fix the retorts tightly with wire rope so that the retorts can't move in the container

Before delivery, our professional technician will do trial run for each product to check until everything is functional, you also can come to our factory and test our machine together with us.
