The fluid bed dryer (Fluidized Bed Dryer) is equipment used to reduce the moisture content of pharmaceutical powder and granules. The working principle of the fluidized bed dryer starts when hot air is introduced at high pressure through a perforated bed of moist solid particulates.
Fluid Bed Dryer Uses and Appliions. 15. Feb. 2018. Fluid bed dryers work on the principle of fluidization, a process in which hot gas or air is introduced into the spaces between solid particles. Upward forces on the particles increase as the air''s velocity increases causing them to equal the gravitational forces below.
Carrier Vibrating fluid bed dryers and coolers are the perfect solution for processing fragile or temperature sensitive materials. The low amplitude vibration and reduced fluidizing velocity create a gentle bed, which causes less degradation than with static fluid beds or other mechanical dryers.

Fluidized bed dryer (also called fluid bed dryer) is a kind of equipment used extensively in the pharmaceutical industries to reduce moisture content of pharmaceutical powder and granules. The equipment works on a principle of fluidization of the feed materials. In fluidization process, hot air is introduced at high
Nov 09, 2010 · Placebo granules consisting of lactose monohydrate, corn starch, and polyvinylpyrrolidone were prepared using deionized water in a highshear mixer and dried in a conical fluidized bed dryer at various superficial gas velocities. Acoustic, vibration, and pressure data obtained over the course of
Apr 04, 2013 · In fluidized bed dryer the design of the instrument should be: Should occupy the small place. Based on our requirement we can go for horizontal or vertical. All technical considerations should be kept in mind while doing the design. Every fluid bed dryer
THE WORLD OF THE FLUID BED Top technology in the production of pharmaceutical solids. The development of the fluid bed since the end of the 1950s is unique in the pharmaceuticals industry. Initially used as a simple yet extremely effective dryer, fluid bed systems quickly developed into granulators with the use of spray nozzles.
Working Principle: Preheated gas (air) is passed into the product layer under controlled velocity after being uniformed by the distributor so as to create a fluidized state. The raw material is fed into the bed. The dehydration process can take place under very good heat & mass transfer conditions (good uniformity of the material in the bed).
Fluid Bed Dryers and Coolers Heyl & Patterson fluid bed dryers are among the most efficient and costeffective on the market. We have conventional designs available for powders and granular materials, as well as unique designs for materials which exhibit characteristics not normally conducive to fluid bed processing, such as sludges, filter cakes,
The fluid bed dryer TG 200 is used in quality control, sample preparation and R&D departments. It permits the gentle drying of organic, inorganic, chemical or pharmaceutical bulk materials without localized overheating. Suitable materials can be coarse, fine, crystalline, fibrous or leafy.
A fluid bed dryer is a kind of equipment which can be used for appliions like drying of powders, mixing of powders and agglomeration. This is efficiently employed for appliions in chemical, pharmaceutical, dyetuff, foodstuff, dairy and various other process industries.
Two and Three Stage Spray Drying With a Fluidized Bed. Principles of Fluid Beds. bed where the residence time of the product is longer and the temperature of the drying air lower than in the spray dryer. This principle forms the basis of the development of the
Working Principle of Fluid Bed Dryers. The atmospheric air is sucked in the dryer through 5/10 micron filter by an efficient dynamically balanced fan driven by an electric motor. The clean air then passes over the electric heaters steam or oil radiator provided with temperature controller.
