FERCHER Energy-Spraytunnel in the food production industry

In this example, the exhaust air from the deep fryer and the steam potato peeling system is sprayed out in a potato processing plant using a FERCHER energy spray tunnel type EST-D-1800.

The fine water droplets of the spray water absorb the heat from the hot exhaust air that is passed through the spray tunnel and at the same time clean the exhaust air of macroscopic dirt particles.

Because the spray water is contaminated, among other things, by potato peel residue, the water cannot yet be used directly in the process. In this operation, approximately one gigawatt hour of heating energy is saved, with a payback period of approximately two years.

Our heat exchangers can also be installed outdoors. They then feature special drainage holes and can be operated frost-proof even in winter without the need for antifreeze.
