Types of Fluid Bed Dryer

What is a Fluid bed dryer?

In order to lower the moisture content of raw components like powder and granules,  fluidized bed dryers or fluid bed dryer are type of machinery that is widely employed in the pharmaceutical industry. This equipment’s operation comprises fluidizing the materials that are put into it. In this procedure, a perforated bed of moist solid particles is used to bring hot air into the system at a high temperature and pressure. The solids, which are in a somewhat wet state and suspended in an airstream, are removed from the bottom (fluidized state). As soon as the wet solid makes direct contact with hot gases, heat transfer starts to happen. The evaporated liquid is eliminated by the dry gas. Sometimes, some of the gas leaving gets recycled.

When and where is a fluid bed dryer used?

Pharmaceutical production processes that involve granulation frequently employ fluidized bed dryers. Granulation is a method of drying the material to achieve the necessary moisture content for the production of properly compacted medication pellets.

The material dries quickly since the Fluid Bed Dryer has a high drying rate. Due to this characteristic, the machine excels in producing a high output.

The usage of a fluid bed dryer has been made to produce artificial resins. Agrochemicals, ceramics, food, fertilizers, and other products can all use this machine. A machine type known as B-FBD is appropriate for the material that needs to be dried in the decreasing-rate drying zone.

Fluid bed dryers has many types here we can say:

The main types are Horizontal fluid bed dryer and Vertical fluid bed dryer.

Horizontal fluid bed dryer or Horizontal fluidized bed dryer equipment:

The material is continually delivered into the model’s rectangular process chamber, where it is dried while moving horizontally to the output port, where the dry product is subsequently ejected. With the dam gates put in the chamber, the operational circumstances, such as material moving speed or floating conditions, can be changed. There are bed sizes ranging from 0.5 to 18 meters2. After drying, the dried product may be cooled in the chamber’s cooling area.

It has the following features:

1. continuously running
2. volumetric thermal coefficient that is high
3. offered in a sanitary design
4. Drying times are flexible.
5. Even for lumped or agglomerated goods, product discharge is simple.
6. Easy to use, check, and require little maintenance

Vertical fluid bed dryer or Vertical fluidized dryer equipment

This dryer’s fan, which is located at the upper portion of the device, introduces the air stream. Following its heating in an air heater, this air rises through the material in the drying chambers. It has a wire mesh support built into the bottom of it. At the top of the chamber, a bag collection fitting allows all the material to be lifted and only allow air to pass through.

The solid dosage form line, which also contains a vacuum conveyor, bin blender, high shear granulator, conical mill, fluid bed dryer, and packing machine, includes vertical fluid bed dryers as essential equipment.

It has the following features:

1. There is a wheel dehumidification system.
2. Dust collector made of carbon steel or stainless steel (AISI 304)
3. All the parameters can be printed and made memorable.
4. Significantly shorter process times, quick drying, and uniform
5. Intelligent touch screen control system by Siemens
6. In the product container, there are no dead zones.
7. Material processing for varying densities
8. Fluidized bed dryer and high shear mixer are compatible and many more.

Other fluid bed dryers :

• Conventional Fluidized Bed Dryer
• Batch fluidized bed dryers
• Continuous fluidized dryers
• Semi-continuous fluidized bed dryers
• Well-mixed, continuous fluidized dryers
• Plug flow fluidized bed dryer

Modified Fluidized Bed Dryer

Fluidized bed dryer benefits(Advantages):

1. Due to the fluidized bed dryer’s effective heating, a batch of tablets can be dried in 20 to 30 minutes.
2. It is simple to regulate the fluidized bed dryer’s temperature.
3. Continuously, the same temperature is maintained.
4. The fluidized bed dryer creates goods that flow freely.
5. This planet is very easy to handle, and personnel costs are also decreased.
6. Due to its ability to run constantly, the horizontal fluidized bed dryer has limitless potential for utilization.
7. There are no lumps developing.
8. Particle by particle drying of the material has occurred.
9. Between the particles and the gas in a fluidized bed dryer, there is a high mass and high heat transfer phenomenon.

Disadvantages of Fluidized Bed Dryers:

• The Fluid Bed Dryer is where the particle typically disintegrates.
• Only a small variety of materials are dried in a fluidized bed dryer.
• The size of the particles is relatively considerable in a fluidized bed dryer.
• processing of particles with a needle or platelet shape is challenging.
• Erosion happens as a result of a particle colliding with a pipe or a vessel wall.
• If small particles and are less effective, the bubbling bed is harder to predict.
• Predicting a non-uniform flow pattern is challenging.
• It is challenging to carry out fluidization processes on a small scale as opposed to an industrial size because of the complicated structure and other complexities.
