Industrial dryers that use gas to suspend materials in a fluidized state are known as fluid bed dryers. Typically, this gas is air, however other gases such as nitrogen and carbon dioxide might also fall under this category. The gas is passed through a bed of solids, which causes the solids to be suspended in the gas.

In the pharmaceutical, food, and mineral processing sectors, fluid bed dryers are employed. Drying delicate or heat-sensitive goods is a great use for them because they don't come into direct contact with the heating element.

Using air to speed up the drying process, a quick dryer is a type of dryer. Damp objects, such as laundry or dishes, are commonly dried using rapid dryers.

To cover something with a different material, you use a tablet coater.

Products are dried using hot air in a fluid-bed dryer. Hot air is blasted through a perforated plate onto the product. The product is dried in the dryer with hot air and then removed from the dryer.

High-velocity air is used in rapid dryers to quickly dry items. Using high-speed air, the dryer is used to dry the product. The dryer then removes the finished product. Tablets are coated using a tablet coater, a coating machine. On a rotating platform, the material is applied to the tablet and the tablet is rotated. Finally, the tablet is removed from the machine and flushed out.

Many types of fluid bed dryers can be used to dry a variety of products including powdered fertilizer and polymers. Many other materials can be dried with them as well.

It is the movement of material from a solid state to a fluid state that is the basis of a fluid bed dryer's operation. A perforated distribution plate is used to distribute hot gas or air into the material chamber. Flowing through the spaces between solid particles, this hot gas causes the particles to expand and contract. A particle's upward force equalizes the gravitational force exerted below it in direct proportion to an increase in gas or air velocity.

As a result, the particles are fluidized and appear to float in a bubbling liquid bed, giving the illusion of a bubble. Moving like water is now possible with what was once solid. A drying process that is both efficient and consistent is achieved because each particle is in direct contact with and surrounded by hot gas or air.

Granulator is a Fluid Bed Dryer

Powders present a unique set of challenges in a wide range of industries. It is difficult to transport them because their packaging is uneven and erratic. So powders must be crystallized into more dense granules with better flow and uniformity through crystallization. To make larger doses of a drug or active ingredient, granulation is used in the pharmaceutical industry, for example, to combine various basic powder components. Combined with a quick dryer, granulation systems can do the drying, mixing, granulation, finishing, and chilling all at once.


The Role of Dryers in Pharmaceutical Production

One of the most important businesses to benefit from fluidized-bed drying has been the pharmaceutical industry. By drying pharmaceutical granules and powders in a fluid bed drier, the product's moisture content can be reliably reduced. Drying products on trays have been replaced by a faster, more reliable process that produces a more uniform end product than the previous way thanks to fluid bed drying technology.

When it comes to drying pharmaceutical products, fluid-bed dryers are the greatest option out there. Temperatures can be regulated to ensure that the granules are sufficiently dried using this technique. If the air coming into the dryer is excessively hot, drying might be slowed or even halted. This can lead to the formation of a surface crust, preventing moisture from the deeper layers from reaching the surface.
