Fluidised Bed Processor, 250V, Heating Media Electric Steam, Material SS

Vj instruments has introduced the dynamic air bed processor, A revolutionary dryer and coater, Adapted to handle smaller trial batches of pellets. Our new fluidized bed machine offers multiple processing providing both flexibility and cost benefits. Bottom spray coating this processing option uses the energy and controls the fluid bed in order to establish a pneumatic mass transport inside a special insert, Which is consisted of a perforated bottom screen with defined free areas. This uniform statistical residence time of all particles within the layer zone produces a very uniform coating. As a result of the high kinetic energy offered by the pneumatic mass flow moist particles are separated, As such allowing the individual coating of even very small particles. Due to the nozzle being positioned directly inside the product and concurrently spraying a premature viscosity change of the protective finish droplet is avoided. All these features result in the highest possible coating quality, Which is imperatively required to produce defined and reproducible drug delivery profiles. Top spray coating spray coating is appropriate for use for all fluid be it, Bed systems in batch or continuous operation or if the film is applied from a sprayed solution or suspension. For this processing option from the parameters has to be chosen to avoid agglomeration, I. E. Liquid bridges between the air suspended particles. If spraying a solution or suspension the liquid only operates as a vehicle to deliver the coating material to the outermost layer of the substrate. The excellence of the coating extensively is contingent upon the statistical residence time of the particles in the coating zone. For a classic fluid bed unit only top, Spray coating is possible. Bottom, Spray arrangement can be made by the replacement of container. A perfect film is generally not required for but care, This function must be taken that the droplets should not be too viscous before touching in pursuit, The substrate of maintain a good spreadability. As however neither the nor the, Particle motion travel distance of droplet from nozzle to substrate the film, Is uniform structure is generally rather porous, But nevertheless measuring as much as the above described requirements.
