Mark Heimann, engineer of the CPM Roskamp Champion Company, of Waterloo, Iowa thinks there may be a need for flake cooling at selected feedlots.CPM, Roskamp Champion is a merger of California Pellet Mill Company and the Roskamp Champion Company.Roskamp, an old-line manufacturer of roller mills and other feed manufacturing machinery.The merged company manufactures, sells and services pellet mills, pellet mill coolers, and roller mills of various sizes.
What type of cooler is needed?Mr. Heimann says horizontal, vertical, or counter-flow coolers are applicable to cool/dry steam flaked grain.Here are his comments:
1. Counter flow offers the best ambient air drying and cooling. (No heat added.) 2.Horizontal are easiest to equip with heaters for additional drying.3.Vertical coolers occupy less floor space.Pre-heaters can be installed in the air intake stream.These pre-heaters are steam coils for horizontal and vertical coolers only, according to Mr. Heimann.

Mr. Heimann's report says the dryer/cooler removes 5-8% moisture and within 10 degrees of the air that is used for the cooling/drying process.
