Fluid bed dryers are often employed with the spray dryers and granulation systems for effective drying,. They can be designed in either batch or continuous type fluid bed dryer. Sugar can also be dried in a vibro fluidized bed dryer, also called a vfbd dryer.

Used for cereals, tabletting granules, salt, coffee, and dried vegetables. The mechanical movement of the fluidized bed dryer strengthens this effect.

Whenever you’re choosing a motor, some critical fluid bed dryer specifications to consider include energy consumption in kw and speed of rotation in revolutions/minute. Implying, by using fbd equipment, you can achieve a suitable moisture content in either powders or granules.

Consider The Dimensions And Weight Of The Fluid Bed Dryer.

The principle of fluidized bed dryer: The mechanical movement of the fluidized bed dryer strengthens this effect. These are preferred when fine sohds are involved, and are used commonly for drying fine coal.

In This Type Of Fluid Bed Dryer, A Vibrating Conveyor Moves The Product Through The Dryer, Exposing It To Updrafts Or Air Or Gas.

As a result of the fluidization, intense turbulence is created in the mass, including a rapid drying action. A coal dryer that depends on a mass of particles being fluidized by passing a stream of hot air through it. The direct contact between particles and air/gas is possible in fluid bed system.

It Is Through This Air Or Gas That The Sugar Is Brought Into A Liquid State, Causing High Heat Transfer That Is Enhanced By The Vibrating Motions.

Vibro fluidized bed dryers are highly efficient. In fluidization process, hot air or gas flow is introduced through the bed of solid particulates. Fluidized bed dryers use an upward flow of heated air and mechanical shaking to create a fluidized effect in powders.

Cool Incoming Air Absorbs Heat From The Surface Of Heated Pipes.

As the velocity increases, upward drag forces on the particles increase and at a stage become equal. Here any type of inert gas or air is used. Cyclones / filters at the gas outlet with possibility to recycle the fines to the fluidized bed.

Sugar Can Also Be Dried In A Vibro Fluidized Bed Dryer, Also Called A Vfbd Dryer.

With this information, you’ll know the total space needed to install the fluidized bed machine. (1978) and dunham et al. This results in an optimal mix of gas and product so that high heat transfer and an optimum physical reaction speed are achieved.
