Oct 21, 2015· The sizing and design of a rotary dryer is a complex process involving a number of factors and considerations. This presentation looks at the importance of custom rotary drum dryer design over a one-size-fits-all solution, and the many material characteristics and environmental factors that should be considered during the design process.
Rotary Dryers A Rotary Dryer uses a rotating cylindrical drum, which acts as a container for the uniform transfer of thermal energy from a hot gas stream to a moisture laden product, for the purpose of moisture reduction in the product. Wet product is introduced into the inlet of the drum where it is dried as it is conveyed to the drum's outlet.

conduction (contact or indirect dryers), radiation or volumetrically by placing the wet material in a microwave or radio frequency electromagnetic field. Over 85 percent of industrial dryers are of the convective type with hot air or direct combustion gases as the drying medium. Over 99 percent of the applications involve removal of water.
Rotary Dryers The foodstuff is contained in a horizontal inclined cylinder through which it travels, being heated either by air flow through the cylinder, or by conduction of heat from the cylinder walls. In some …
Rotary dryers are a class of dryer commonly used in industry to dry particulate solids (Keey, 1972). They are made of a long cylindrical shell that is rotated. The shell is usually slightly inclined to the horizontal to induce solids flow from one end of the dryer to the other. In direct heat rotary dryers, a hot
Rotary dryers were more expensive to design than fluidized bed dryers. Operationally, however, it is the other way around due to the favored heat transfer achieved in rotary dryers. Conveyor‐belt dryers lie somewhere between producing satisfactory results in terms of both design and operation. Case studies on foods and inorganics are included ...

-Rotary dryer The food stuff is contained in a horizontal cylinder through which it travels. Heated either by air flow through the cylinder or by conduction of heat from the cylinder walls.-Fluidised-bed dryer Warm air is blown upwards directly underneath the food, causing it to flow and remain separated. This procedure is suitable for small items.
Thus, this study used a co-current rotary dryer. The drying gas temperature was set as 400 °C, which is the optimum drying temperature for typical rotary dryers (Li et al., 2012). The residence time of the EFB was set so as not to exceed the average residence time of a typical rotary dryer …
