Know More About Indirect Heat Transfer Dryer

Screw Heat Exchanger- Introduction. The screw heat exchanger is an indirect exchanger in which bulk materials, such as powders, granules and pastes can be heated, cooled, or dried. The heating and cooling medium is separated from the product by means of a barrier. The barrier is often a heated barrier or body surrounded by the product.

Indirect Rotary Dryers - Vulcan® Drying Systems

How the Indirect Heat Dryer Works. Materials are fed into a rotary drum that is encased in a stationary refractory lined furnace. This furnace casing has a series of burners mounted down the length of one side firing into the furnace chamber. As the material progresses down the length of the unit, it is subjected to different temperatures in ...

Indirect Thermal Desorption System

The °Celsius screw heat exchanger is an indirect heat exchanger based on a transfer screw design and is used for cooling, heating, and drying powders, granules, and pastes. The products can vary from the cooling of sand to the melting of chocolate. The heat is transferred via the trough wall, screw shaft, screw flight, or a combination.
