Fluid Bed Processing involves drying, cooling, agglomeration, granulation and coating of particulate materials. It is ideal for heat sensitive and non heat sensitive products in Pharmaceuticals, Biotech, Nutraceuticals, Cosmetic, Chemicals, Biochemical, Food, Dairy, Confectionery, Agrochemical, Herbals, Ceramics, Detergents and Pharma Institutes.
The Fluid Bed Mixing and Drying Process : The Fluid Bed system have 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. Fines get agglomerated to larger granules particles thus providing large size
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 fluid / binder / starch pest by using top spraying system. The top spraying system provided with spraying nozzle and precise dosing peristaltic pump. The fluidized powder is wetted until liquid bridges are formed between particles. 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.
This process is used to apply a coating to the granules or pellets. This process knows as wurster coater. In this process the spray is done inside a hollow cylinder and from the bottom of this cylinder the pellets are allowed in small quantity to enter the hollow cylindrical tube. Than the particles are passing the bottom spray guns in orderly manner quickly moving upward the tubes to avoid agglomeration. Once they are outside the wurster compartment, they move downward outside the compartment where they dry another layer of coating can be supplied. Since the movement of the particle or pellets inside the wurster chamber totally controlled in ensures uniform.
The Coater is capable of handling any of the following process..
