Fluid Bed Dryers
GEA Process Engineering Inc.
•Product Brochure: Fluid Bed Technology
Gentle, rapid drying of powders and particles
The product to be dried is fluidized by passing hot air through it. The process achieves fast heat transfer making it very efficient, yet gentle on the product.
Capacity: from 50g to several ton/batch or several ton/hr.
History and description of batch fluid bed processors
Batch fluid bed processing has been used in the pharmaceutical industry for the past 30 years. The technology was originally developed specifically for rapid drying. Over the years, fluid bed processing has come into routine use for other applications such as granulation, agglomeration, air suspension coating, rotary pelletization, and powder and solution layering, but the principle of the fluid bed processor has not changed.
A fluidized bed is a bed of solid particles with a stream of air or gas passing upward through the particles at a rate great enough to set them in motion. As the air travels through the particle bed, it imparts unique properties to the bed. For example, the bed behaves as a liquid. It is possible to propagate wave motion, which creates the potential for improved mixing. In a bubbling fluidized bed, no temperature gradient exists within the mass of the fluidized particles. This isothermal property results from the intense particle activity in the system. Thus, the fluid bed can be used to dry the wet product, agglomerate particles, improve flow properties, instantize the product, or produce coated particles for controlled release or taste masking. Modular systems designed to carry out multiple processes in which only a container change is necessary to change the type of unit operation being performed have been developed by all the manufacturers of fluid-bed processors.
Although the basic process of the fluid bed has not changed much, the versatility of fluid-bed processing has evolved over the past 30 years in response to the demands of the pharmaceutical industry, the guidance of regulatory agencies, and competitive innovation on the part of equipment manufacturers.
