A grain dryer consists of a vertical cylindrical Chegg

Transcribed image text: A grain dryer consists of a vertical cylindrical hopper through which hot air is blown. The air enters the base at 1.38 bar, 65 degree C, 50% RH. At the top, saturated air is discharged into the atmosphere at 1.035 bar, 60 degree C. Estimate the moisture picked up by 1 kg of dry air, and the total enthalpy change between the entering and leaving streams

US5233766A - Vertical grain dryer - Google Patents

The vertical grain drier of this invention is designed to thoroughly mix grain as it is descending in a vertical chute, and uniformly dry the grain by hot air passed through the chute from a central plenum. The grain is uniformly mixed and dried by being passed back and forth between a series of inclined baffles which alternately redirect the grain toward the inside and outside screens
