Granulation in a fluidized bed granulator is achieved by suspending the powder in the air of the fluidized bed and then spraying the binder solution from nozzles that are either positioned above or below the powder bed depending on the type of the granulator.
What is principle of fluidized bed coater?
The Principle of Fluidized Bed Dryer: If air is allowed to flow through a bed of solid powdered material in the upward direction with the velocity greater than the settling rate of the particles, the solid particles will be blown up and become suspended in the air stream.
What is fluid bed dryer in pharmaceutical industry?
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. In this process, hot air at a high temperature and pressure is introduced in the system through a perforated bed of moist solid particulate.
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 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 fluid bed processor technology?
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 fluid bed equipment?
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 equipment works on a principle of fluidization of the feed materials.
What is the process of drying?
Drying is a mass transfer process consisting of the removal of water or another solvent by evaporation from a solid, semi-solid or liquid. A source of heat and an agent to remove the vapor produced by the process are often involved.
How is FBD CFM 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 multi mill?
variable force swing beaters
Multimill. It operates on the principle of variable force swing beaters having both knife and impact edges rotating within a selected screen to get the required size reduction.
What is a fluid bed processor?
Fluid bed processor, gpcg. PRINCIPLE A fluidized bed is a bed of solid particles through which hot air is passed at high pressure through air distribution plate/bottom of container. The particles are lifted from the bottom and suspended in air stream. This condition is called fluidized state.
How does a fluidized bed dryer work?
The Principle of Fluidized Bed Dryer: If air is allowed to flow through a bed of solid powdered material in the upward direction with the velocity greater than the settling rate of the particles, the solid particles will be blown up and become suspended in the air stream.
What is the fluid bed granulation process?
Liquid Addition Evaporation Rate 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 the main structure of the filterfluid bed processor?
Fluid Bed Processor : Main Structure 1 Pre-filter G4 2 Intermediate Filter F8 3 Wheel dehumidification 4 Electric heating system 5 Cold & Hot Air Valve 6 Final Filter H13 7 Temperature& Humidity Sensor
