Working principle:

Loading：Load filled tomato paste pouches into the retort chamber through the double – door system to prevent heat loss and contamination.
Sealing & Initiating Sterilization：Seal the retort and start the sterilization cycle. The water spray system distributes hot water uniformly, ensuring all pouches reach the required sterilization temperature to eliminate harmful microorganisms.
Monitoring & Control：An automated PLC system continuously monitors and adjusts temperature, pressure, and time to maintain optimal sterilization conditions.
Cooling：Gradually cool the pouches at the end of the cycle to stabilize internal pressure and avoid package damage.
Unloading：Once cooled, open the doors and unload the sterilized tomato paste pouches for further processing or packaging.
