Fluidized Bed Dryer Working

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.

Fluidized bed dryer working.

Plugging of distributor perforated holes. How a ventilex fluidized bed dryer works working principle of the ventilex fluidized bed dryer. Solids from dropping into wind box or gas plenum located beneath the fluidized bed. Principle and working of fluidized bed dryer fbd fluidized bed dryer fbd is well known and widely used equipment in granulation area of pharmaceutical manufacturing.

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. In this process hot gas or air is introduced through a perforated distribution plate into the area holding the material. A fluid bed dryer is a kind of equipment which can be used for applications like drying of powders mixing of powders and agglomeration. If not a large quantity of.

More flexibility in that the sequence of unit operations can be switched or adjusted. Better suited for heat sensitive materials. This hot gas pumps through the spaces between solid particles. Fluidized bed drying is the optimal method for controlled gentle and even drying of wet solids.

A fluid bed dryer made. This is efficiently employed for applications in chemical pharmaceutical dyetuff foodstuff dairy and various other process industries. Quality control level of risk for a continuous drying process the process conditions must be strictly controlled. This is usually achieved by the introduction of pressurized fluid through the particulate medium.

The mechanical movement of the fluidized bed dryer strengthens this effect. Poor fluidization quality of solids in certain regions in the fluidized bed dryer. The intensive heat mass exchange of the fluidized bed product makes this method particularly effective and time saving. In a fluidized bed dryer a product or solid is made fluid by an upward moving flow of gas.

Fluid bed dryers are often employed with the spray dryers and granulation systems for effective drying mixing granualtion finishing and cooling of powdered substances. Material remains free flowing and uniform. 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. Fluidized bed dryer 1.

Fluidized bed dryer has a high drying rate and the material is dried in a very short time.
