The cooling principle
The high-performance cooling tunnel operates with more intense convection cooling from above and intensive cold water contact cooling below. The two cooling systems can be regulated independently of one another.
Fields of application
With their combination of more intense convection cooling from above and cold water cooling from below, Type KK Thermo-Flow® plus cooling tunnels have been specially designed for cooling product fillings.
SOLLICH Thermo-Flow® plus cooling tunnels are available in belt widths from 320 mm to 3000 mm and in lengths of up to 100 m.
Patented temperature controls
Unfortunately, if production is interrupted the result in practical terms is often a change of temperature in the cooling tunnel. If required, Type KK cooling tunnels may be fitted with a new patented temperature control device which ensures that the temperatures at the tunnel entrance and exit always remain constant, irrespective of the volume of products passing through the tunnel. In the commissioning phase, or if production is interrupted, temperature conditions in the cooling tunnel are automatically adjusted, so that the coating always sets under optimum physical conditions. The result is consistently good gloss and a long shelf life for the coating. The formation of unstable beta crystals as a result of poor cooling practice is prevented.
