thermodynamic calculations of heat and mass balance equations. To design a drying system for a material, lab-scale experiments are generally needed to obtain the material properties and desirable operation conditions once the dryer type is selected carefully. Once the design requirements are specified, a drying
The process of sizing a rotary dryer is one of precise engineering involving complex calculations and meticulous design. While the process is not well simplified into a few paragraphs, an explanation can be offered as to some of the concepts behind the process of rotary dryer sizing.
and drying systems have been commercialized. These are Simprosys for design and simulation of drying and evaporation systems (Gong and Mujumdar, 2008), dryPak for dryer design calculations for various gas-solvent systems (Pakowski, 1994), and DrySel for dryer selection marketed by Aspen Technology.

adiabatic or direct dryers, while when heat is transferred from an external medium it is known as non-adiabatic or indirect dryers. Dryers heated by dielectric, radiant or microwave energy are also non adiabatic. Some units combine adiabatic and non adiabatic drying; they are known as direct-indirect dryers.
In turn, the retention time will help determine the needs of a rotary dryer. Retention time is the amount of time that something needs to remain in the rotary dryer, and can be controlled by many factors. If a material needs to be in the rotary dryer for a long period of time, a longer rotary dryer is needed.
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.

Design Issues: Mechanical Dryers 1. Introduction: There are three generic forms of mechanical dryer commonly found in use today. The vertical dryer, the horizontal dryer and the silo or stationary-bed dryer. These are batch dryers which naturally fit the batch pattern dictated by coffee processing, following, as it does, daily (or less frequent)
