Water Spray process is an overpressure process, it's different from Saturated Steam process in that air can be introduced into the vessel during sterilization. Preheat Tank is an OPTIONAL to preheat the process water while operator is entering the process recipe for hot filling products. During process, water is sprayed over the containers from different angles, steam can go through the other loop of the heat exchanger to heat the process water or directly injected into vessel. Water Spray process can be used for various packages thermal processing, excellent temperature distribution and efficient heat transfer since Innovaster selects all top-class brands components to provide the high-quality retorts and service to our customers worldwide and our know-how. HMI controls provide a user-friendly interface to retort control.
Main Features
1. Uniform heat distribution and no blind angle for sterilization;
2. Preheat the process water in the upper storage vessel in advance, shorten the sterilization time and improve the working efficiency;
3. Process water can be used repeatedly, saving energy, time, manpower, and reducing the production cost;
4. Short process time and high temperature preserve food flavor and nutrition;
5. Perfect pressure control system, efficiently avoiding the containers deformation and package break;
6. Continually monitor the temperature inside the retort, keeping the temperature difference ±0.5°C;
7. famous brand PLC automatic control system and touch screen, easy to operate;
8. System will make alarm calls automatically when the temperature, the pressure, the water level, or any other kinds of error occur.

1. What kind of batch retorts are available?
Batch retorts are available in several configurations. They can be static or agitating style machines. Innovaster custom
designs and manufactures solutions for all types retort processing systems starting with your container.
Contact with our sales consultant to discover more about Innovaster Retorts system.
2. Why is overpressure applied in batch retorts process?
Overpressure is important in the cooling phases of a retort process because as cooling water is introduced into the retort it collapses the steam injected in the heating step. Without sufficient introduction of air overpressure during cooling, the
pressure in the retort can suddenly drop due to steam collapse thus creating a vacuum situation in the retort. If this happens the pressure differential between the outside environment and the temperature/pressure environment inside the container becomes too great thus causing the container to burst (otherwise known as "buckling").
