In manufacturing processes where drying is required, the cost of drying can approach 60– 70% of the total cost (Hamdullahpur et al., 2002). Thus, to increase efficiency with drying systems has been an important research area. Due to the lack of theoretical design knowledge and large amount of variables, the dryer design is often completed experimentally and then scaled up from the results ...

 · A rotary dryer is said to be of the direct type if, by virtue of its design, heat is added to or removed from the solids by direct exchange between the gas and solids. The direct heat dryers are the simplest and the most economical class. They are used when direct contact with the hot gas or air is not detrimental to the fed. When high temperature is required for the drying process in a direct ...

The rotary dryer cylinder is tilted slightly compared with horizontal. Materials and hot flue gas goes into the rotary dryer cilinder from the higher end. During the rotation of the cylinder, the material by gravity goes into the lower end. When the wet material is in the process of moving forward in the rotary dryer cylinder body, the lifting plates inside the rotary dryer cilinder makes the ...
