Thermal treatment

What about the process ?

Heating and sterilisation phase: 

The steam, which has no physical barrier, is introduced directly and automatically into the autoclave and is distributed geometrically by distributors. A ventilation system, permanently controlled by the regulation system, and specially designed to have an optimized performance, facilitates the circulation of steam in any part of the equipment in order to guarantee a perfect temperature homogeneity.

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 between the baskets.

When the sterilization temperature is reached, the fan remains in operation and thus participates in an even more effective heat penetration at the heart of the product. Steam has the best calorific value of all services (3 to 100 times better than water for example). The high precision measuring system coupled with the SAMANTHA © regulation system allows to have a pressure and backpressure treatment without inertia, in real time, before, during and after the entire sterilization phase.

A Cooling step:

The re-circulated water comes from retained steam condensate to which is added an amount of pre-cooling water.

The gradual addition of cold water is automatically controlled and eliminates the risk of "thermal shock" and ensures the temperature is ramped down.

Throughout the Heating & Cooling steps, the electronic process controller monitors temperature and pressure inside the retort chamber.

This range is accessible for all production industry with its door closing manually, half-automatic or totally automatic, its range of size and its large choice of option.
