Cooling tunnels are constructed in stainless steel for durability, cleaning and hygiene purposes.

PTL tunnels meet the latest standards in hygienic design, ensuring fast, simple and thorough cleaning throughout all areas of the tunnels. From the hoods, beds, drive and evaporator sections, all areas can be accessed, cleaned and dried easily.

In recent years, the industry has seen a rise in allergen cases and an elevation in allergen regulations. PTL’s design focuses on eliminating areas where product and allergens can accumulate, by sealing areas, making items removable and/or enabling all parts of the tunnel to be washed. At the same time, PTL machinery provides optimal cooling efficiency to ensure that control and maximum production are achieved.

Cooling tunnels are used to cool chocolate and compound, bar slabs, cookies and other food products.

They have separate top and bottom cooling zones, with air cooling or glycol cool beds for more intense under-belt cooling.

A variety of profile setups can be achieved, depending on the product being processed and the heat loads. Tunnels are equipped with lift-up hoods (on both sides, depending on width) enabling easy access for cleaning.

The evaporator is under-belt, hermetically sealed and washdown.

There is a robust tracking system.

PTL cooling tunnels can come with belt washers that in many cases clean the belt continually during production, meaning you can start and finish production with a clean belt and drive section.
