Fluidized Bed Dryer Diagram

The technology is also suitable for post drying of spray granulated or extruded products with very low residual moisture.

Fluidized bed dryer diagram.

Fluidized bed dryer is a dryer that uses the functions of fluidization such as excellent mixing gas dispersion and heat exchanging. This principle forms the basis of the development of the three stage drier. In heinen köhl standard process air will be conditioned in energy units following the closed loop principle. The process air coming from the perforated bottom of the trough creates a homogeneous fluidized carpet.

The process air is supplied to the bed through a perforated distributor plate and flows through the bed of solids at a sufficient velocity to support the weight of particles in a fluidized state. The product can be removed from the drying chamber with a higher moisture content and the final drying takes place in the external fluid bed where the residence time of the product is longer and the temperature of the drying air lower than in the spray dryer. Fluidized bed dryer has a high drying rate and the material is dried in a very short time. Fluidized bed drying is the optimal method for controlled gentle and even drying of wet solids.

Material remains free flowing and uniform. Dryers can be broken up into two main types. Spray dryers or 5. Senieer also has a 500kg fluid bed dryer even bigger we can custom design for you.

Fluid bed granulators tray dryers 4. Fluidized bed dryer also called fluid bed dryer is a kind of equipment used extensively in the pharmaceutical industries to reduce the moisture content of pharmaceutical powder and granules. Fbd bags are finger like in structure to increase the surface area of the drying bed that helps to increase the drying rate and decrease the drying time during the fluidized bed drying process. The equipment works on a principle of fluidization of the feed materials.

Depending on requirements the product properties can be influenced and enhanced. Fluidized bed dryers coolers. Dryers are used to remove liquids or moisture from bulk solids powders parts continuous sheets or other liquids by evaporation or sublimation. By installing heat exchanging tubes or plates high heating efficiency is realized without increasing the hot gas volume.

Spray coating in a fluidized bed system produces an optimal surface coating for your product through even application of a film material. Materials processed in a fluidized bed dryer or cooler float on a cushion of air or gas. The intensive heat mass exchange of the fluidized bed product makes this method particularly effective and time saving.
