USAGE：
Skyline Fluid-bed Multi-processor is added bottom spray on the base of FBG series Fluid-bed Granulator, thus can realize drying, granulating and bottom spray coating on one machine, and with function of mixing raw material, granulation, dying and coating for granules or pellets. The equipment is PLC auto controlled and well satisfies with the current GMP and the National Pharmacopoeia.
Working principle:
The intake air is processed from the inlet AHU through filters and heated, then lead into the lower bowl. The material is blow up evenly by hot air which passes through air distribution plate of product bowl, then forms continuous fluidized state and dried evenly by hot air.
In case of top spray for fluid iz ed granulation, use top spray movable product bowl, the binder is top sprayed through spray guns in diffuse chamber into the product bowl, and spray onto the material surface atomized by compressed air. The product granules cohere each other by the binder and get the binder bridge to form the core granules, then grow up to form required wet granules, which the binder dried evenly by hot air and finally get dry granules.
In case of bottom spray for coating, use bottom spray movable product bowl, the binder changes to spray from bottom spray guns and atomized. The granules or pellet sprayed from bottom to top inside of fluidized chamber and coated by coating solutions, then fall back along the wall of bottom spray product bowl and dried by hot air, which back to bottom are sprayed again from fluidized chamber and repeat coating process.
