Thermal treatment What about the process ?
Sterilization by Water Spraying (directly heated by Steam injection): Water is injected at the bottom of the retort until it reaches a certain level to allow the pump to correctly function (or the water is keep from the previous cycle) using an LAGARDE AUTOCLAVES exclusivity. With this special device, spray nozzles, this water is in turn heated by injecting steam directly in the retort (no external heat exchanger requested) and between each stack. For the cooling, the water is sucked in by the pump and circulates on treated products. These same spray nozzles designed and patented by LAGARDE AUTOCLAVES which are located on the side of each baskets ensure the performance cooling also. Satured steam : The air exhaust valve is opened at the beginning of the cycle and some satured steam is injected in-between the baskets to chase the air out of the vessel. Once the required temperature is obtained, the valve is closed and the environment inside the retort corresponds to the temperature and pressure requirements of the recipre for the product, therefore the temperature and the pressure are linked together. The steam, which has no physical barrier, is introduced directly and automatically into the autoclave and is distributed geometrically by some distributors, controlled permanently by the regulation system, and specially designed to have an optimized performance. It is not necessary to preheat water neither in the bottom of the autoclave, nor in the pipe, nor added water, since steam is injected directly into the autoclave. |
