Principle 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 KÖHL standard process air will be conditioned in energy units following the closed loop principle. In this2.1 Working principle of bed dryer Fluid bed dryer works on a principle of fluidization process. In fluidization process, hot air or gas flow is introduced through the bed of solid particulates. This gas or air will move upwards through the spaces between the particles. As the velocity increases, upward drag forces onDESIGN OF FLUIDIZED BED DRYER IRJET

Fluidized bed dryers ScienceDirect

In several nations, the fluidized bed grain dryer has been a popular drying technology. It is ideal for high-moisture grains like paddy, parboiled rice, maize, and soya. When opposed to older grain dryers, it dries grain much faster. As a result, the drying system is small in comparison to its resilience.For each processed batch of 150 kg in the fluid bed dryer, this translates into an energy saving of around 18.5 kWh, giving an annual energy saving of over 3.700 kWh.

Fluid bed granulation is a key process step of solid dosage production, during which binding agents are added to the fluidized powdered product. As a result, the product forms granules, i.e., larger particles than those present in the initial mixture. Particle sizes can be controlled via pre-defined parameters.The principle behind a Fluidized Bed Dryer revolves around the concept of fluidization. Fluidization is a process in which solid particles are made to behave like a fluid by passing a gas or liquid through them. In the case of FBDs, a stream of hot air or gas is passed through a bed of solid particles, causing them to become suspended and actFluidized Bed Dryer -FBD: Principle, Working Process
