Division 4.12.2 Techniques for cooling slurry

United Kingdom

Technique	Description
Slurry cooling pipes	A reduction of slurry temperature (usually less than 12 °C) is achieved by installing a cooling system placed above the slurry, above the concrete floor or cast into the floor. The applied cooling intensity can be from 10 W/m² to 50 W/m² for gestating sows and fattening pigs housed on partly slatted floors. The system consists of pipes in which a refrigerant or water is circulated. The pipes are connected to a heat exchange device to recover energy that may be used for heating other parts of the farm. The pit or the channels need to be frequently emptied due to a relatively small exchanging surface of the pipes.
