What is fluid bed dryer?
Fluid or Fluidised bed dryer is a kind of equipment used extensively in the pharmaceutical industries to reduce the moisture content in raw ingredients like powder and granules. The working principle of this equipment includes fluidization of the fed materials.
Why is it called fluidized bed dryer?
The Principle of Fluidized Bed Dryer: At this stage, this solid bed looks like the boiling liquid, therefore this stage is called as fluidized. Use of hot air to fluidizing the bed will increase the drying rate of the material.
What does fluidized bed mean?
Definition of fluidized bed : a bed of small solid particles (as in a coal burning furnace) suspended and kept in motion by an upward flow of a fluid (such as a gas) — called also fluid bed.
What is 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.
What is the difference between FBP and FBD?
FBD is used for only drying and, FBP is used for Granulation, Drying, Agglomeration, and Coating Process.
What are the advantages of fluidized bed dryer?
Advantages of Fluid Bed Dryer Fluidized Bed Dryers Guarantee Fast and Homogeneous Drying. Fluid Bed Dryer is Suitable for Heat Sensitive Products. Fluidized Bed Ensures Efficiency in Material Drying. Handling Fluidized Bed Dryer is Easy and Less Labor Intensive.
What is fluidization principle?
1 The principle of fluidization. Fluidization is the process of stationary solid particles brought into a dynamic “fluid-like” state by an upward stream of fluid (gas or liquid) (Fan & Zhu, 2005).
What are the types of granulation?
Granulation process can be divided into two types: wet granulation that utilize a liquid in the process and dry granulation that requires no liquid.
What is CFM in fluid bed dryer?
(3000-3300 cubic foot per minute (cfm)) was. excessive for the amount of material in the fluid bed. dryer. The rapid rise in the exhaust air temperature.
What are the application of FBD?
Fluid bed dryers, as their name suggests, are used for drying materials such as granules, tablets, powders, fertilizers, and plastics. They are particularly popular in production industries like: Chemical. Pharmaceutical.
What is the meaning of fluidization?
Fluidization is defined as a method to keep solid particles floating in an upward direction (Figure 5) in a flow of gas or liquid. In freezing, fluidization occurs when particles of a similar shape and size are subjected to an upward stream of low-temperature air.
