The disk and the bath are separated at a controlled rate to form a monolayer of liquid on the disk as the disk is positioned in a gas-filled volume. The separation may be by moving the disk out of the liquid bath, and the controlled rate is generally not less than the maximum rate at which a meniscus will form between the liquid bath and the surface of the disk when the liquid bath and the disk are separated.

Hot gas directed into the volume and across the disk and out of the volume continuously transfers thermal energy to the disk. The directing of the gas out of the volume is independent of the separation of the bath and the disk.

Abstract: A grain drying apparatus uses the heat of an engine to aid in the evaporative process. The grain drying apparatus provides an engine 20 which is used to power a fan 40. Waste heat generated by the engine is transferred to air driven by fan 40 through air duct 70 by three principle means.

A finned heat exchanger tube 60, also carried within the elongated air duct, transfers heat to the air flow within the duct. An air intake pipe transfers air under pressure into a fuel tank, where the air mixes with fuel vapors. The air and fuel vapor mix is then transferred to the exhaust pipe, where combustion takes place, thereby increasing the heat flow from the finned heat exchanger.

Abstract: In a process for drying a substance, particularly wood shavings, wood chips or wood flakes, a partial stream of the vapor-gas mixture is separated after passing through the drying drum before the vapor-gas mixture is led to a first heat exchanger.

The flue gases are led through the aforementioned supplementary heat exchanger before they reach the first heat exchanger whereby they are brought down to a lower temperature. In this way the thermal stress on the material of the heat exchanger elements of the first heat exchanger is reduced, thereby increasing the life of these heat exchanger elements.

Abstract: Moist sewage sludge is dried in a sludge dryer having several zones. The initial moisture content of the sewage sludge may range up to 80% by weight, while the dried bulk material shall have a remainder moisture content of about 5% by weight. The drying gas temperature is maintained at a level up to 50.degree.

A gas drying agent, such as a hygroscopic material is used in the gas dryer and the gas drying agent itself is regenerated by withdrawing moisture therefrom in a regenerating circuit.
