Fluidized Bed Dryer Working

Fluidized bed drying is the optimal method for controlled gentle and even drying of wet solids.

Fluidized bed dryer working.

The technology is also suitable for post drying of spray granulated or extruded products with very low residual moisture. How a ventilex fluidized bed dryer works working principle of the ventilex fluidized bed dryer. Poor fluidization quality of solids in certain regions in the fluidized bed dryer. In this process hot gas or air is introduced through a perforated distribution plate into the area holding the material.

Fluidized bed dryer 1. This results in the medium then having many properties and characteristics of normal fluids such as the ability to free flow under gravity or to be pumped using fluid type technologies. Material remains free flowing and uniform. Fluidized bed dryer has a high drying rate and the material is dried in a very short time.

A fluid bed dryer made. It is used in the granulation process for drying the material to get desired moisture content in the tablet formulation granules required for perfect compression of tablets. If not a large quantity of. Quality control level of risk for a continuous drying process the process conditions must be strictly controlled.

Plugging of distributor perforated holes. Fluid bed dryers are often employed with the spray dryers and granulation systems for effective drying mixing granualtion finishing and cooling of powdered substances. A fluidized bed is a physical phenomenon occurring when a quantity of a solid particulate substance is placed under appropriate conditions to cause a solid fluid mixture to behave as a fluid. More flexibility in that the sequence of unit operations can be switched or adjusted.

This hot gas pumps through the spaces between solid particles. 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. Better suited for heat sensitive materials. In a fluidized bed dryer a product or solid is made fluid by an upward moving flow of gas.

This is efficiently employed for applications in chemical pharmaceutical dyetuff foodstuff dairy and various other process industries. The intensive heat mass exchange of the fluidized bed product makes this method particularly effective and time saving. Solids from dropping into wind box or gas plenum located beneath the fluidized bed. The mechanical movement of the fluidized bed dryer strengthens this effect.

A fluid bed dryer is a kind of equipment which can be used for applications like drying of powders mixing of powders and agglomeration.
