What is fluid bed coating?

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 fluid bed process?

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

What is FBD coating?

Spray coating in a fluidized bed system produces an optimal surface coating for your product through even application of a film material. The aqueous or organic solution evaporates and the solids it contains form the coating layer.

What is the principle of fluid bed coater?

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 FBD dryer?

Drying, heating, cooling. 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.

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 a fluid bed granulator?

Fluidized bed granulator is one of the commonly used processing equipment in the pharmaceutical industries. It is a multi-purpose equipment in that mixing, granulation and drying are all carried out in the same equipment. The equipment operates in a bubbling bed regime.
