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 (except 20L model that
works by steam)

4.1 Temperature control

The autoclave uses two temperature probes:
• Water temperature probe:
It indicates the water temperature of the autoclave. Located at the bottom of
the autoclave.
• Product temperature or "heart" probe:
Indicates the temperature of the product.
