Medium sized rotary drum dryer used for drying DDGS (distillers dried grains with solubles), a co-product of the Ethanol industry. What is a Rotary Drum Dryer? Rotary drum dryers are the work horse of the drying industry because of their capacity, efficiency, and ability to be adapted to new g: Computer control. To better understand the underlying phenomena taking place in an industrial rotary dryer and to determine the optimum operating conditions, a simulator in which the solids transportation, the gas flow, and the heat and mass transfer are modeled is currently being developed. This paper describes the use of interactive perfect mixers in series to model the solids transportation within an Cited by:
Example Size of the rotary dryer can be estimated for the following case. A moist non hygroscopic granular solid at C is to be dried from 20% initial moisture to % final moisture in a rotary dryer at a rate of kg/h. The hot air enters the dryer at C with a humidity of With condition that the temperature of theFile Size: KB. Transport Properties in the Drying of Solids. Dimitris Marinos-Kouris and Z.B. Maroulis.

• Solids can be dropped slowly through a slow-moving gas stream, as in a rotary dryer • Gases can be blown through a bed of solids that fluidize the particles. In this case, the solids are moving, as in a fluidized-bed dryer • Solids can enter a high-velocity hot gas stream and can be conveyed pneumatically to a collector (flash dryer)Missing: Computer control.
