How fluid bed technology works for cooling heating and ...

Oct 19 2020 · Fluid bed technology is used for cooling heating and drying of bulk solids materials. Fluid bed heat exchange takes place by passing a gas (most commonly air) through a perforated distributor plate which then flows through a layer (bed) of solids. The air performs two functions. First the air flows through the bed of solids at a velocity ...

Principle of Fluidized Bed Dryer - Laafon Galaxy ...

Nov 04 2020 · Principle of Fluidized Bed Dryer: When the air is introduced in upside with a velocity more than the velocity of particle settling then the solid particles start to blowing up and sustain in the air stream. This stage makes the solid bed boiling liquid. Thus the process is called fluidized.

Fluid Bed Dryer - How Fluid Bed Dryer Works for Drying ...

Fluid bed dryer works on a principle of fluidization of the materials. In fluidization process hot air or gas flow is introduced through the bed of solid particulates. This gas or air will move upwards through the spaces between the particles. As the velocity increases upward drag forces on the particles increase and at a stage become equal ...

Drying processes | Industrialheatpumps.nl

Drying is an important industrial process. Conventional dryers circulate air over a product. Due to this the air is cooled down and becomes humid. Normally this humid air that contains a lot of energy is exhausted. With the use of a heat pump the energy in exhaust air can be recovered for both and dehumidification of the air. An innovative solution invented by De Kleijn Energy ...
