The PM-Luft grain cooler will cool grain to safe storage temperatures regardless of ambient conditions. Cooled air is distributed in the silo or flat storage through a duct system placed at the bottom of the grain storage. When the cooled air meets the warm grain, a cool zone is created. This cool zone moves up through the grain pile until it reaches the top. The cooler is fully automatic and operated through a PLC system using patented software. The operator only has to select the type of grain to be chilled (11 different grains plus manual operation), temperature and moisture content of the grain. PM-Luft is based in Kvanum, Sweden.
