Fluid bed dryers from FBD are also faster and gentler than traditional drying cabinets.

A fluid bed dryer (also known as a rapid dryer or fluidized bed dryer) is a type of drying equipment that is commonly used to reduce the moisture content of foods, pharmaceuticals, chemical powders, and granules.

In addition, fluid bed dryers are faster and gentler than traditional drying cabinets. Food products, polymers, soils, chemicals, pharmaceuticals, minerals, and waste materials all benefit from their use.

Fluid bed dryers produce consistent, repeatable results with the right settings. Dry materials with moisture contents ranging from 0% to more than 80%.

The machine is known for drastically reducing the drying time of drug compounds larger than 50 microns, which are typically used in tablets and capsules. Traditionally, moisture was removed from Active Pharmaceutical Ingredients using trays and vacuum dryers.

Both Tray and Vacuum Dryers are trolleys with insulated tray chambers stacked on top of one another. In the trays, the material to be dried is placed. By circulating hot air in tray dryers, electric heaters and blow fans ensure heat transfer. Steam is passed through the annular space between a jacket and the vessel walls in a vacuum dryer, which operates below atmospheric pressure.

While these manual and semi-mechanical processes are effective in practise, they significantly increase drying time, which increases production batch time. As a result, the plant's production capacity is reduced. Furthermore, traditional dryers necessitate a long period of downtime for maintenance and management. Fluidization, on the other hand, is used in a fluid bed dryer to convert the material from a static solid-like state to a dynamic fluid-like state.

The bowl of a Fluid Bed Dryer granulator is a detachable perforated bottom chamber made of stainless steel. The wet solids are lifted and suspended by the steady air stream. The moisture is vaporised as a result of the heat transfer, preparing solid particles for further processing. Using computational fluid dynamics, we have conducted innovative and practical research (CFD). CFD validation improves velocity and temperature accuracy by precisely controlling process parameters.

Desiccant dehumidifiers can also help speed up the drying process. Separate centrifugal fans for process air intake and exhaust are used in a desiccant dehumidifier. Approximately 75% of the rotor face area is exposed to humid air. Because the moisture has been extracted to the silica gel by the absorption process, the resulting air is dry after crossing the rotor.

Fluidization results in a high moisture removal rate, so rapid dryers are critical in producing a uniform dried material output. To operate and clean the machine, FBDs require low operating and maintenance costs as well as fewer human resources. As a result, smooth automation can eliminate the need for human oversight.

Rapid dryers used in flexible production must have programmable batch capacities and controls. Chemical compounds release moisture at varying temperatures and relative humidity until they reach their maximum allowable temperature, with varying drying times.

To ensure this, the operator should have complete control over parameters such as airflow and feed rate in order to achieve the desired result. In the drying of heat-sensitive materials, fluid bed dryers provide control over airflow and humidity.

Fluid bed dryers, on the other hand, are not suitable for sticky semisolid drying materials because they require particle movement. Conventional dryers are ideal for drying sticky substances in this case.
