What is the principle of fluid bed processor?
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.
How does a fluid bed granulator work?
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.
How does a fluid bed dryer work?
In short: A continuous fluid-bed system is a machine in which a continuous flow of “wet” powder, granular or flakes material is conveyed over a perforated bed. Hot drying air is blown through the holes of a perforated plate. The wet solids are lifted from the bottom and causes the solids to behave as a fluid.
What are the applications of FBD?
A fluid bed dryer is an excellent drying system that can be used for applications like drying of powders, mixing of powders and agglomeration. This is efficiently employed for applications in chemical, pharmaceutical, dyetuff, foodstuff, dairy and various other process industries.
What is 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.
What is fluid bed equipment?
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.
What is the principle of granulation?
Granulation is a process in which powder particles are made to adhere to each other, resulting in larger, multi-particle entities, so called granules. If such a process is performed without adding liquids, this is called dry granulation.
What is fluidized bed agglomeration?
Fluidized bed agglomeration consists in spraying liquid (e.g. binder solution or water) onto, or into, a fluidized bed of particles. Sprayed liquid droplets wet the particle surface rendering it “sticky” due either to the formation of a film of binder solution, or to the modification of the particle surface viscosity.
What are the advantages of fluidized bed dryer?
The advantages of fluid bed drying include low investment and maintenance costs, large-scale continuous production, lower air temperatures than spray drying and a relatively short drying time compared to freeze drying and vacuum drying. However, non-granular samples cannot be dried using fluid bed drying.
How is FBD capacity calculated?
Flow rate = Velocity x Area of cross section. Total capacity required = 884 / 0.8 = 1105 m3/hr = 651 CFM.
Fluid bed processor plays a pivotal role in pharmaceutical material processing. That is, understand the principle of fluidized bed processor control variable parameters to suit the unique machinery and process requirements of your applications. I know this information can be overwhelming for a newbie in the fluid bed equipment industry.
How to generate positive pressure inside the fluid bed chamber?
When used to generate positive pressure inside the fluid bed chamber, the inlet air explosion-proof valve shall be closed, so that the explosive air will be discharged from the dedicated venting pipe to the outdoor area.
What is the best fluid bed processor for scale up studies?
FBM Series fluid bed processor senieer include one of the most trusted models in its performance class for feasibility and scale-up studies in the scientific research institute, worldwide medical university laboratory research center and laboratory of pharmaceutical company, It is ideal for scale-ups to the pilot scale.
What is FBM series fluid bed processor?
Whether the spraying nozzle is at the top (top spray), at the bottom (fluid bed processor bottom spray) or on the side (tangent spray): FBM Series Fluid Bed Processor definition performs all important fluid bed processes. FBM Series fluid bed processor capacity is conceived specifically for smaller batch sizes.
