  • Continuous Flow Dryers - Extension

    2017-6-29 · In-bin continuous-flow dryers are among the more efficient continuous-flow type dryers - about 2000 Btu per pound of water removed - which is about 20 to 30 percent more efficient than a traditional cross-flow dryer. This type of dryer can be retrofitted into an existing bin, and can be used to store grain at the end of the drying season.
