Fluid Bed Dryer: Benefits & Application

The fluid bed dryer is a manufacturing tool used to lower the moisture content from granules, powder or food products. This powerful machinery significantly reduces the drying time of the given medical compounds that are larger than 50 microns, utilized for manufacturing tablets and capsules. The fluid bed dryer works on the process of fluidization. The fluid bed dryer consists of a perforated plate ( a sheet of metal or plastic with holes) through which the hot air is blown and gets distributed as the product lies on the perforated plate. The product will float due to the pressure, and the heat gets transferred by the products that float. It leads to all the moisture getting sucked out of the granules, giving super dry results.

Advantages of Using a Fluid Bed Dryer

• Uniform Drying

During the drying process, the particles float in the air which ensures that the moisture sucked from every particle uniformely. Each of the particles comes in direct contact with hot air, which ensures a uniform drying process.

• Perfect for Heat-Sensitive Products

Pharmaceutical products are sensitive and cannot withstand extreme heat. So, oven drying cannot be a perfect solution.  A fluid bed dryer is apt in suck a suitation, in which the the product is not in direct contact with extreme heat. The modern fluidized bed dryer works on the sensors which can monitor the parameters of the products during the process.

• Efficient Process

The fluidized bed dryer principle offers high efficiency. The fluidazation process ensures a faster and uniform drying process. Moreover, the stream of air in a fluidized bed surrounds every particle for optimal drying. It can effectively dry materials at lower temperatures. Therefore, all your heat-sensitive products will be safe.

• No Hot Spots in Dried Products

The particles are suspended in the air and come in direct contact with the stream of hot air. At any given instance, every particle moves within the fluid bed dryer drying compartment, while hot air flows through the entire system. This ensures uniform heat distribution, and the drying process remains safe for heat-sensitive materials.

• High Thermal Efficiency

The fluidized dryer is an efficient equipment. You can also save energy as drying techniques take a shorter time. With the particles being suspended in air in fluidized bed drying systems, hot air and particles come in direct contact with each other. It results in high heat and mass transfer rates.

The result will be more precise and quick at low temperatures, which will be cost-efficient for the business owners. With the advanced gas recirculation system of the heating equipment, you can achieve high thermal efficiency during the operations. 

• Affordable Solution

Fluid bed drying machines can be counted as an affordable solution for heat-sensitive products. The machine is flexible to most manufacturing and processing needs. Even the small fluid bed dryers are fully automated which provides easy operation and process monitoring. 

• Requires no human intervention throughout the process

• Low maintenance costs

• Modular designs for easy assembly

• Easy to achieve large-scale continuous production

• Easy to control temperature and other process variables

Applications of the Fluid Bed Dryer

The common application of the fluid bed dryer is the pharmaceutical industry. This advanced machinery has long overtaken the traditional drying trays, which were not so efficient and also increased the expense of the operations. Using the fluid bed dryer, the spray granulation transforms the water-containing paste, solution, granules without any risk of contamination. 

The fluid bed dryer also helps in agglomeration, which is the process of assembling the particles into cohesive units like pellets and granules. It makes the process easier to transport the fine powders due to their loose packing. The process of logistics is made so much easier through this process of transportation and distribution. 

The fluid bed dryer is also used for employing the tangential roto granulator to coat the powder layer on mini-tablets and capsules accurately. Thus, the patients can easily swallow the pills without any problems, thanks to the polymer coating.

Additionally, some of the industries using the fluid bed dryer are:

• Chemical Industries

• Pharmaceutical Industries

• Metal Industries

• Dye Industries 

• Food Processing Industries

• Dairy Industries
