Tunnel pasteurizer

Comac tunnel pasteurizer is equipped with an automatic system applied to the pasteurization areas, which avoids the over-pasteurization of the beverage in case the internal conveyor stops.

At Comac’s you can find five types of single deck tunnel pasteurizers of different sizes – all manufactured in collaboration with CFT Group:


• 8.6 sq m
• 10 sq m
• 16 sq m
• 42 sq m
• 60 sq m


Inside a Comac tunnel pasteurizer

The tunnel unit for the pasteurization of the already packaged product consists of a stainless steel AISI 304 solid structure that is subjected to an abrasive blasting and protective coating.


The inner part of our tunnel pasteurizer features two anchored tanks that feed the upper showers, while all the instruments of command and control of both the mechanical cycle and the temperature are positioned outside.


Inside the machine, the bottles and the cans lie on a plastic chain and, thanks to an external gear motor, go forward throughout the various sections encountering the upper showers, at different temperatures, until they reach the exit. The feed rate of the bottles and cans in the tunnel pasteurizer can be set from an operating panel that allows to vary the duration of the cycle, which has been designed to save cooling water and set by appropriate instrumentation that keeps the water temperature in the tanks constant.


All tanks are equipped with doors on one side to allow the cleaning and periodic maintenance of the unit, and with double panel filters extractable from the pumps side. The tempered glass doors installed on the entry and exit sides of the machine allow the manual removal of any containers remaining on the bearing surface at the end of work.


An automatic system for the tunnel pasteurizer

The machine is equipped with an automatic system, applied to the pasteurization areas, which allows to avoid the over-pasteurization of the product in case the internal conveyor stops.


The stainless steel electrical panel is provided with an operator panel that allows to verify and set all the control parameters of the machine and with an electronic chart recorder that stores the values of all the variables that control all the pasteurization steps.
