Fluid Bed Equipment-Processor- Top Spray Granulation

Application & Process

Prism Fluid Bed Processing involves drying, cooling, agglomeration and granulation of particulate materials. It is ideal for heat sensitive and non heat sensitive products in Pharmaceuticals, Biotech, Nutraceuticals, Chemicals, Biochemical, Food, Dairy, Confectionery, Agrochemical, Herbals, Detergent and Pharma Institutes.

Depending on the application required Prism Fluid Bed Processor can be configured into designs as follows:

1. The Fluid Bed Mixing and Drying Process: The Fluid Bed system has a bed of solid particles which are fluidized by passing a stream of air upward through a specially designed perforated sheet. The upward velocity of air is so maintained so as to slightly lift the solid particles and set them in motion. This motion can be utilized to bring about mixing as well as forward movement of the solids particles. The air is heated and the process hot air evaporates the fluid and dries the solids.

2. The Fluid Bed Processor with Top spraying system for Agglomeration and Granulation Process: The process is used in fluid beds to form granules form a fine powder. The fluidized powder is wetted with Binder solution by using top spraying system. The top spraying system provided with spraying nozzle and precise dosing peristaltic pump. The fluidized powder gets wetted and creates liquid bridges between particles and convert powder into granules. The continuous hot air ensure drying of granules and preventing of create lumps during process. Segregation of powder doesn’t take place as different powder is glued together on a micro scale. Since there is no impinging force in fluid bed equipments the granules are weak and having good solubility. Once the granules are made they are dried in the equipment using hot air. This technology used for formed granules for Tabletting, capsule, dust free process, free flow properties, good dispensability and excellent solubility due to porous structure.
