Description

The Bieffe Co heat treatment tunnels are designed to adapt to any type of product, including glass or plastic containers, jars and cans of all sizes, dimensions and for any production capacity.
The control panels of our machines—also designed and built in-house—allow all details of the process to be managed, authorising the operator to easily act on all parameters in a simple and intuitive way. The panel components are European, with availability guaranteed worldwide.

Automatic over-pasteurisation control (optional)
In case of prolonged transport shutdown, the system automatically takes action and progressively reduces the temperature of the pre-pasteurisation and pasteurisation sections. Upon the subsequent restart, the inner belt is reactivated only when the set points are reached. The sequence and duration of the temperature reductions is controlled by the PLC in an entirely automatic way. The system guarantees a maximum over-pasteurisation of 60%.
For the reduction in temperature, water from the heating and cooling sections is used, availing of recirculation pumps. The exchangers of the pre-pasteurisation and pasteurisation sections are dimensioned in such a way as to permit the restoration of the set points in the shortest possible time.
