Rotary drying is one of the many drying methods existing in unit operations of chemical engineering. The drying takes place in rotary dryers, …
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.
A rotary dryer is one of the most popular types of industrial dryers composed of a steel cylindrical shell that rotates around a shaft (Mujumdar, 2006; Yliniemi, Koskinen, & Leiviskä, 1998).The cylindrical shell has a length of 5–90 m, a diameter of 0.3–5 m, and a rotation of 1–5.The wet material enters the cylinder from the upper part and is discharged from the lower part (Fig. 3.7).
One of the most common mistakes made in acquiring or designing a rotary dryer is the application of a one-size-fits-all design. The applications in which rotary dryers are employed vary substantially in their level of duty, and in the specific challenges presented by each job. As such, a one-size-fits-all solution almost always falls short.

For evaporating moisture from concentrates or other products from plant operations, Rotary Dryers are designed and constructed for high efficiency and economy in fuel consumption. Whenever possible to apply heat direct to the material to be dried, Rotary Dryers of the Direct Heating Design are used. If it is not possible to apply heat direct to the material to be dried, …
3.3 Rotary Dryers 17 3.3Rotary Dryers Consists of a revolving hollow cylindrical shell, horizontal or slightly inclined towards the outlet. Figure 5: Photograph of a rotary dryer. As the shell rotates, internal ights lift the solids and shower them down through the interior of the shell. May be direct or indirect contact or a combination of both.
Drying of Bagasse is important process to shorten the lead time in Jaggery production.Over 400 types of dryers have been reported in the literature and more than 100 distinct types,few are commonly available. There are many methods available for bagasse drying but the rotary dryer is one of the most economical and simple design.
Rotary drying is a complicated process involving simultaneous heat, mass transfer, and momentum transfer phenomena. A substantial number of papers have been published on rotary dryers covering various aspects such as drying, resi-dence time distribution, and solids transportation. A static model for counter-current rotary dryer was developed by

Rotary dryers are comprised of a rotating drum, into which the material is fed, in combination with the drying air. Flights, or lifters, pick up the material from the …
The drying method is based on passing hot air through the material situated on the rotary drum. A rotary hot air dryer was chosen for the design due to the fact that there are many advantages possessed by this type of design for this particular process. The main advantages of rotary hot-air dryer are following: fruits and drying of the remaining.
This Project Standards and Specifications is intended to cover minimum requirements for process design of dryers used in oil, gas, and petrochemical process plants.
MECHANICAL DESIGN OF ROTARY DRIER Flight design: Number of flights = 3 x D. = 3 x2.09 =6.27 ≈ 7 flights are required using lip angle of 45°. Radial height is taken as 1/8 of diameter, Radial height = 2.09/8 = 0.2615m.
