4. Introduction

The "STERIL-FOOD" autoclave has been designed to perform thermal treatments
of pasteurization or sterilization of containers (metal, glass, plastic) with food
content. The autoclave has the capacity to store 10 heat treatment programs
with 6 steps each.
All programs can be programmed by the user.
The autoclave works by spraying superheated water to transmit the heat (tem-
perature) on the containers subjected to heat treatment.

4.1 Temperature control

The autoclave uses two temperature probes:
• Water temperature probe:
Controls the water temperature of the autoclave. Located at the bottom of the
autoclave.
• Product temperature or "heart" probe:
Indicates the temperature of the product.
It is through the temperature continuously recorded by this probe (if it is inserted
in the container) that the autoclave software calculates the value Fo (F sub 0) the
cloSiNg pRobe
jaR lid
product has reached throughout the heat treatment.
pRodUct
The Fo value is calculated by the autoclave software from the temperature recorded
every minute by the heart probe inserted in a container and the thermoresistance

characteristics of three types of microorganism according to the thermal treatment
to which the product is subjected:

In case of a sterilization process: Clostridium Botulinum
In case of pasteurization: Bacillus coagulans or Streptococcus faecalis D
