Pick Heaters, Inc.

Pick Direct Steam Injection Heaters provide efficient ethanol production solutions. The open design of the heater allows slurry flow without obstruction. The Pick Heater does not rely on high liquid & steam velocity for mixing to occur. Steam is fully condensed within the heater body. The result is smooth operation with no straight-run piping requirements and lower liquid pressure drop. In addition to mash cooking, Pick Heaters can be used in the following applications within an ethanol plant: process make-up water for mash tanks, hot water make-up for yeast tanks, Clean-in-Place (CIP) for fermenters and process tanks, plant washdown- hose stations, and any other heating requirements.
