Fluidized bed is one of the reactors using fluidization 24. Many industrial plants prefer this method which has high efficiency. The purpose of initial fluidized bed design was coal gasification 79. Recently the petrochemical industry uses fluidized bed for catalytic processes such as Residue Fluidized Catalytic Cracking RFCC 1.

2015-8-25Principle of the Fluidized Bed Dryer A vibratory conveyor is leading the tobacco in an even layer through two drying zones. The process air coming from the perforated bottom of the trough creates a homogeneous fluidized carpet. In HEINEN KHL standard process air will be conditioned in energy units following the closed loop principle. In this.

Fluidized bed drying is the optimal method for controlled, gentle and even drying of wet solids. The intensive heatmass exchange of the fluidized bed product makes this method particularly effective and time-saving. The technology is also suitable for post-drying of spray granulated or extruded products with very low residual moisture.

In fluidized bed dryer the design of the instrument should be Should occupy the small place. Based on our requirement we can go for horizontal or vertical. All technical considerations should be kept in mind while doing the design. Every fluid bed dryer must have explosion relief device of required size 23.

Solids can be dropped slowly through a slow-moving gas stream, as in a rotary dryer Gases can be blown through a bed of solids that fluidize the particles. In this case, the solids are moving, as in a fluidized-bed dryer Solids can enter a high-velocity hot gas stream and can be conveyed pneumatically to a collector flash dryer.

This is a technical drawing of fluid bed dryer and granulator. From these technical drawings, I am sure the structural difference in this fluid bed equipment is quite clear. Apart from the structural design, as a fluid bed granulation manufacturer, we may include different intricate components to optimize operations.

2020-5-5Fluidized bed dryer has a high drying rate and the material is dried in a very short time. Material remains free-flowing and uniform. 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.
