An experimental rotary dryer designed with concurrent flow system comprising two primary parts, a double cylinder and a discharge cover, is shown in Fig. 12.1.Forward movement of paddy takes place by inclination angle and rotary motion of the cylinder, while air is blown through the cylinder by the suction fan located on top of the discharge cover.
Oct 21, 2015nbsp018332the 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.
Principles of rotary drying. the directly heated rotary dryer operates on the principle of lifting and showering the product through a hot gas stream moving either in parallel or counter-flow whereas with the indirect dryer, which is more suited to fine and dusty materials, there is little or no contact between the product and the drying gases since they are heated from the outside, via a ...
