The steam tunnel is utilized for heating an emulsion from + 5° C up to ± 90° C core, depending on capacity, rope size, specific heat and recipe.

The tunnel mainly exists of 2 chambers through which a processing belt is continuously running. The tunnel is sealed on both sides with water locks. The top hood can be lifted automatically for easy cleaning purposes. The bottom hood is bolted and can be opened for maintenance purposes. Heat is transferred to the product in 2 ways:

• Steam injected into the top hood condenses on the product surface and heats the emulsion

• The steam injected below the processing belt condenses on the belt and heats the emulsion from the bottom.
