Direct-heat rotary dryers can operate on fuel oils, natural gas, propane or coal. In addition, steam-heated clean air and flue gases may be used as a heating medium. Indirect-heat rotary dryers are available in steam tube designs and standard rotary models. When the standard rotary design is used, convection heat transfer is employed.
Working principle: The tube bundle dryer is a rotary drum internally equipped with steam or thermal oil heated tubes, so hot gas circulation is not required. This results in a very high thermal efficiency and a minimal flow of exhaust steam needing to be treated. It is especially suitable for large flows of products which require medium to long
In Steam Rotary Dryers steam is used as heating medium: steam is conveyed inside a series of tubes. The heat transfer occurs from the tubes wall to the product by radiation and conduction even if the temperature of metal surfaces is generally low, as a result of the saturation temperature of steam which depends on its inlet pressure.
Superheated steam is frequently used in the power industry, with other typical applications including foodstuffs, and solvent-laden minerals. Advantages to Drying with Superheated Steam. Utilizing superheated steam as the drying medium allows for the same efficiencies as a direct rotary dryer, typically heated by gas. And although this type of ...
Rotary Drum Dryer Working Principle: Wet material goes into the feeding hopper by belt conveyor or bucket elevator, then through the feeder goes into the feed pipe. The feed pipe slope is greater than the natural inclination of the materials, so that the material can inflow the rotary dryer smoothly.

Working Principle Rotary Double Cone Vacuum Dryers. Raw material is charged in batches & is subjected to indirect heating while at the same time undergoing rotary motion of the cone assembly. The conical shape of the dryer ensures efficient circulation of hot liquid heating media.
Working Principle. Zhengzhou Taida new type MED sludge dryer can reduce materials with 90% moisture to final standard products. Aimed at viscous and cake-forming property of sludge, we improve lifting plate structure of single-pass dryer.
Rotary steam tube dryers dry at a lower temperature, are resilient and can handle significant upsets. Dryers that use steam as a heat source instead of hot air tend to operate with greater thermal efficiency. In addition, the installed cost of steam tube dryers is roughly the same as direct fired dryers.
One of the most common types of indirect-heat rotary dryers is the steam-tube rotary dryer, shown below. It consists of a slowly rotating, almost horizontal shell with heat-transfer tubes along the outside walls. Steam enters the heat-transfer tubes through an inlet at the discharge end of the dryer.
The principal operating procedure for a steam tube dryer is similar to a rotating tube and shell heat exchanger. Steel tubes or pipes are installed inside a rotating drum. A rotary steam joint is utilized to deliver 100-150 PSIG steam which fills the inside of the tubes.
Steam dryer is specially designed for rotary dryers which regard steam as heat source. It applies steam as drying media and adopts indirect dying form. ... slowly. Raw materials will enter feeding inlet of dryer through feeder. With the function of screw belt set in drying tube, raw materials will move to discharge end. ... Working Principle ...
