What is the working principle of fluidized bed dryer?
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 fluidized bed dryer?
Fluidized bed dryer (also called fluid bed dryer) is a kind of equipment used extensively in the pharmaceutical industries to reduce the moisture content of pharmaceutical powder and granules. The vaporized liquid is carried away by the drying gasses. Sometimes to save energy, the exit gas is partially recycled.
What is FBD in pharma?
Fluidized bed dryer (FBD) is well known and widely used equipment in granulation area of pharmaceutical manufacturing. It is used in the granulation process for drying the material to get desired moisture content in the tablet formulation granules required for perfect compression of tablets.
What are the types of fluidized bed?
There are two main types of fluidized bed gasification systems—bubbling fluidized bed and CFB. Depending on the scale of operation, the cyclone separators for capture and recycling of solid particles could be placed either internally or externally.
What should be the air pressure of panel in FBD?
5.7 Check that pressure is proper in pressure indicating switch i.e 0.210 to 0.250 kg/cm2 for panel pressure & 2.0 to 2.60 kg/cm2 for inflatable tube.
What is fluid bed processor?
Fluid Bed Processor is a very good technology to make granules from powder using top spray method. The technology is most suited as the same equipment can be used for top spray granulation, bottom spray coating & drying all 03 parameters in the same equipment thereby reducing the nos of equipment used for a process.
What is fluidized bed material?
A fluidized bed is a state of a two-phase mixture of particulate solid material and fluid, which is widely used in many modern technologies for efficient implementation of various physical and chemical processes. Such materials are called polydisperse materials.
What is a fluid bed dryer used for?
A fluid bed dryer is used for continuous drying of various materials like powders and 2D or 3D dimensional materials up to 100 mm.
What is fluid bed coating?
Fluid Bed Powder Coatings In its simplest form, fluid bed powder coating consists of immersing a hot part into a bed of powder, allowing the powder to melt on the part and build a film, and subsequently providing enough time and heat for this film to flow into a continuous coating.
What is a fluid bed processor?
Fluid Bed Processor. APPLICATION. The purpose of fluid bed processor is to put substances in powdery or granular form into a suspended state. The fluidizing air in this equipment will enable a very efficient heat and mass transfer ( heating, drying, granulating/Coating)
