Full Water Immersion / Technology

Temperature come-up and holding time steps

- A volume of preheated water at a pre-determined temperature is stored in a tank above the retort and is transferred into the treatment retort chamber (total immersion of the packaging)

- This amount of water is circulated by a pump and is heated by steam for maintaining a constant temperature during the desired treatment.

- Temperature control (steam injection in the exchanger) and pressure (injection or venting of compressed-air) are automatically and independently controlled, according to the programme settings of "Tables of set values".

Cooling step

A part of the hot water is put back into the tank (energy saving). The rest of the process water continues to be recirculated and is cooled through a heat exchanger.

During all the Heat & Cooling steps, the electronic process controller monitors temperature and pressure inside the retort chamber. More information.
