A fluid bed dryer diagram, dryer works on the principle of fluidization of the materials. In the 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 on the particles increase and at a stage become equal to the gravitational forces beneath. Hence the bed is said to be fluidized and the particles are suspended in the fluid. There are various advantages of fluid bed dryer in pharmaceutical industries. Some of them are as follows.
Advantages of Fluid Bed Dryer
* High thermal efficiency is achieved when the thermal energy is supplied by the internal heat exchanger
* Low Capital Cost
* Ease of Maintenance and Control
* High Heat and Mass Transfer Rates
In a fluid bed dryer diagram, used for powder drying, initially, the air is sucked inside from the surroundings with a fan-run with an electric motor inside the dryer. The air then passes through a heating system within the dryer and gets heated up. This hot drying air is then made to flow through the bed of the most materials that are laid on a shaking perforated steel bed. This air is introduced with the required velocity and temperature that the bed gets fluidized allowing intimate contact of each particle with the air. As the bed vibrates or shakes, the particles in the bed are carried forward slowly along the length of the dryer. All the moisture present in particles gets sucked by the hot air which then escapes into the dust recovery system and is recycled for further use in the process. The velocity and temperature of the air can be controlled as the particles pass on the bed and hence very wet to sticky materials can also be dried with a fluid bed dryer effectively. The dried material is then fed into the cooling zone where cool air reduces the temperature of the material to the required state. Therefore in this way product or powder drying can be efficiently achieved with the help of a fluid bed dryer.
