Fluidized Bed Dryer Working

Material remains free flowing and uniform.

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. 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. Fluid bed dryers work on the principle of fluidization a process where a material is converted from a static solid like state to a dynamic fluid like state. Plugging of distributor perforated holes.

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. 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. This is efficiently employed for applications in chemical pharmaceutical dyetuff foodstuff dairy and various other process industries. The mechanical movement of the fluidized bed dryer strengthens this effect.

Quality control level of risk for a continuous drying process the process conditions must be strictly controlled. The intensive heat mass 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. 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.

Fluidized bed drying is the optimal method for controlled gentle and even drying of wet solids. Fluidized bed dryer has a high drying rate and the material is dried in a very short time. A fluid bed dryer is a kind of equipment which can be used for applications like drying of powders mixing of powders and agglomeration. Poor fluidization quality of solids in certain regions in the fluidized bed dryer.

If not a large quantity of. How a ventilex fluidized bed dryer works working principle of the ventilex fluidized bed dryer. Better suited for heat sensitive materials. This hot gas pumps through the spaces between solid particles.

This is usually achieved by the introduction of pressurized fluid through the particulate medium. Fluidized bed dryer 1. Fluid bed dryers are often employed with the spray dryers and granulation systems for effective drying mixing granualtion finishing and cooling of powdered substances. Solids from dropping into wind box or gas plenum located beneath the fluidized bed.

In a fluidized bed dryer a product or solid is made fluid by an upward moving flow of gas.
