Full Immersion into Hot Water Retort
A water immersion retort is for sterilization of trays, jars, bottles and cans in water bath process, which is designed with upper preheat water storage vessel and lower sterilization vessels.
Water Spray Retorts utilize a high volume pump with an array of spray nozzles strategically located to create an even temperature distribution. Heating and cooling of this water is made through a plate heat exchanger.
Both the water immersion and spray retort, Generally, Steam is recommended as an economic heating source. For small scale Laboratory and Research Test Retort, electric heating is option.
