Hot Water Spray Retort

Product Details

Innovaster 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 because of our know-how. HMI controls provide a user-friendly interface to retort control.
