Which type of coating is used in fluidized bed method?
Top Spray Coating
Top Spray Coating This process is used for general coatings right up to enteric coating. With top spray coating in the fluid bed (batch and continuous), particles are fluidized in the flow of heated air, which is introduced into the product container via a base plate.
What is fluidized 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 fluidized bed coating used for?
Fluidized Bed Coating The fluidized bed process is used for coatings between 10-15 mils with the final thickness dependent upon part temperature and dip time in the powder. The film can be applied in thickness from 8-125 mils.
What is Wurster coating?
Wurster coating, synonymous with fluid bed microencapsulation, is the encapsulation of discrete particles in a fluidized bed using differential air flow to create a cyclic movement of material. The Wurster coating process can be applied to a range of core materials in numerous particle sizes and shapes.
What is FBP in pharma?
Fluid bed processor (fbp) is a popular material processing technique in different field industries. Quite a several industries use it as a means of transforming the dusty powder into desirable granules. Senieer development of the fluid bed processor since 1988 is unique in the pharmaceuticals industry.
What is tablet coating process?
Tablet coating is the process where coating material is applied to the surface of the tablet to achieve the desired properties of dosage form over the uncoated variety. There are three main processes for tablet coating: sugar coating, film coating, and enteric coating.
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 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 RMG in pharma?
Rapid mixer granulator is widely used equipment in pharmaceutical manufacturing. It is used to mix the pharmaceutical ingredients and make the granules before compression and also called a high shear mixer.
Can a spray coating be used in a fluidized bed system?
Spray coating can be performed – usually in batch processing – in all fluidized bed systems. For some coating applications, a continuous process is also available. The film material is applied as a solution, suspension or melt.
How is Wurster coating used in a fluid bed?
The Wurster coating system is ideally suited for the coating of particles ranging from fine powders (~10 micron) up to small pellets (2-3 mm). It consists of a processing insert that is placed inside a fluid bed processor.
Who is the leader in fluid bed coating?
Coating Place, Inc. has been the leader in Wurster fluid bed coating since our founding in 1976. Wurster coating, synonymous with fluid bed microencapsulation, is the encapsulation of discrete particles in a fluidized bed using differential air flow to create a cyclic movement of material.
Which is the correct way to spray a tablet?
The more effectively the spray system atomizes the coating suspension, the more evenly the tablets get coated. The spray can reach the particles from the top, the bottom or the side. In top spraying, the coating solution is applied counter-currently to the tablets’ motion, as seen on the right.
