How the particles are dried in fluidized bed dryer?

The temperature of air is maximum at the nozzle inlet. Through the nozzles the hot air rises up. This upwind suspends the wet sand particles in a fluidized state. The hot air surrounding the wet sand causes the sand to dry.

Which type of products are used in fluidized bed dryer?

The NARA Fluidized Bed Dryer (FBD) provides high efficiency by fluidizing powder with gas. It is suitable to uniformly dry the processed material which ranges in high moisture content to low moisture content. The wet powder is dried by a fluidized bed incorporating a heat exchange with gas.

What is fluid bed coating?

Fluidized bed coating or granulation is a process by which granules or coated particles are produced in a single piece of equipment by spraying a binder as solution, suspension, or melt onto a fluidized powder bed. This process is sometimes classified as the one-pot system.

What is fluid bed agglomeration process?

The fluid bed granulation process (also known as agglomeration) involves suspending particulates in an air stream and spraying a liquid from the top down onto the fluidized bed. Particles in the path of the spray get slightly wetted and become tacky.

What is the difference between FBD and FBP?

What is the Difference Between FBD and FBP? FBD is used for only drying and, FBP is used for Granulation, Drying, Agglomeration, and Coating Process.

How is FBD capacity calculated?

Flow rate = Velocity x Area of cross section. Total capacity required = 884 / 0.8 = 1105 m3/hr = 651 CFM.

What is the principle of FBD?

Fluid bed dryers work on the principle of fluidization, a process where a material is converted from a static solid-like state to a dynamic fluid-like state. In this process, hot gas or air is introduced through a perforated distribution plate into the area holding the material.

What is the principle of fluid bed coater?

Fluid Bed Coaters are used in coating materials by the fluid bed technology. With fluid bed coating, particles are fluidized and the coating fluid sprayed on and dried. Small droplets and a low viscosity of the spray medium ensure an even product coating.

What is compression coating?

Compression-coated formulations can be used to protect hygroscopic, light-sensitive, oxygen- or acid-labile drugs, or to separate incompatible drugs from each other. They can also be used to achieve controlled release, and a number of studies (2) have evaluated compression-coated time-controlled drug delivery systems.
