Manufacturers of Fluid Bed Dryers

 

A Fluid Bed Dryer is used to dry powders, crystals, and medium-sized pellets quickly and uniformly. The Fluid Bed Dryer is used in the pharmaceutical industry.

A fluidized bed dryer (also known as a rapid dryer) is a piece of equipment used in the pharmaceutical industry to reduce the moisture content of medicinal powders and granules. Wet granules must be dried in order to be compressed into tablets and to change the properties of viscous and sticky materials. Before compression into tablet form and packaging, drying is usually the last stage in the unit process. Many pharmaceutical instruments are available from VJ Instruments, VJ Instruments is the best fluid bed dryer manufacturer.

Hot air is injected at high pressure through a perforated bed of moist solid particles in the fluidization process. The moist solids are raised from the bottom of the tank and suspended in an air stream (fluidized state). Direct contact between the wet solid and the hot gases is used to transfer heat. The drying fumes carry the vaporized liquid away. Exit gas is sometimes partially recycled to conserve energy.

Wet granules, crystalline or coarse materials can all be dried using the fluid bed dryer. It works on the idea of blowing hot air through the bed of the material to be dried at a high velocity, forcing it to fluidize.

The blower on the dryer's exhaust side functions on a no-negative-pressure principle, creating an induced draught that draws fresh air into the dryer. From the bottom of the product container containing the wet material, a stream of hot filtered air is supplied. The air distribution plate and Dutch sieve are included in this container. By creating turbulence in the product container, the air stream passes through the material bed and fluidizes the product particles. Fluidization surrounds each particle with hot air, resulting in rapid and uniform heating and drying. Filter bags at the top of the machine prevent particles from escaping.

Dryers' Importance in the Pharmaceutical Industry

While fluidized bed drying has applications in a variety of industries, it is perhaps most notable in the pharmaceutical industry. The moisture content of pharmaceutical granules and powder can be consistently reduced by employing a fluid bed dryer. The conventional method of drying items in trays has been superseded with fluid bed drying technology, which has resulted in significantly faster drying durations and more consistent drying conditions for a homogenous end product.

Fluid bed dryers are the most effective way to dry a wide range of materials, especially those in the pharmaceutical business. The method allows for precise regulation of the inlet air temperature, ensuring that the proper amount of moisture evaporates from the granule surface. A high incoming air temperature might cause a surface crust, which inhibits deeper moisture from being transferred to the surface, delaying rather than speeding up the drying process.

 

The basic idea is that

Because hot air (gas) or ambient air is allowed to flow upward at high pressure through a perforated bottom of a vessel carrying a bed of particle solids or wet granules, the fluid bed dryer gets its name. The settling rate by which granules/particles remain suspended in a stream of hot air is greater than the velocity of hot air. A fluidized state is the term for this situation. Every granule/particle is thoroughly dried by the heated air that surrounds them.

 

Working conditions:

The material to be dried is placed in the bottom of the dryer in a removable vessel. The air is delivered from below through the prefilter, where it is heated by heaters. At the same time, fans are permitted to work. The bed expands as the air velocity rises, and further expansion creates turbulent particle motion known as fluidization.

In the air stream, the granules/particles remain suspended. When frictional drag on the granules/particles equals the force of gravity, a condition of pressure is reached on a later form of pressure. Due to the high velocity of the gas, the particles ascend in the airstream, resulting in a fluidized state.
