Fluidized bed drying is the optimal method for controlled, gentle and even drying of wet solids. The intensive heat/mass exchange of the fluidized bed product makes this method particularly effective and time-saving. The technology is also suitable for post-drying of spray granulated or extruded products with very low residual moisture.

Oct 01, 2013· In addition to their established Wurster and Top Spray processes for coating and granulation of particles, Glatt recently launched a new technology to their portfolio. This video animation shows ...
The advantages of fluid bed granulation. During fluid bed granulation, high velocity air is used to suspend powdered material within a fluid bed granulator. This specialized, multi-purpose piece of equipment is capable of mixing, granulating and drying, obviating the requirement to use separate instrumentation for each stage of the process.

Apr 02, 2013· Impact of Particle Size. Figure 3 shows the variation of the moisture content and the bed temperature during drying for large particles, moderate particles and mixtures with a targeting moisture content of 20% and drying temperature of 80°C. The drying process for fine particles was also examined in this work. However during drying, the holes in the bed distributer were easily clogged by fine ...
Oct 30, 2009· Fluid bed granulation (FBG) is one of the most widely used and extensively studied processes in pharmaceutical technology. The prime purpose of the FBG is to improve material properties for further processing, i.e., flowability and compactibility. Particle size distribution has a major impact …
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 fluid / binder / starch pest by using top spraying system.
The fluidized bed spray granulation is a method for making free-flowing granulate from liquids. It can be used in different applications in various industries, since the product properties can be varied in many ways by setting process technical parameters and configurations. The granules are suitable for making tablets and, because of their ...
Many clients will come to us and have a specific type of fluid dryer that they're using at their own facility or the facility at which they get their product manufactured. Typically, the fluid bed dryer will either be manufactured by Glatt or GEA Niro. A common client concern we address involves moving from one brand of FBG/FBD to another.
Aug 02, 2011· The pharmaceutical industry has used fluid-bed granulation extensively for several decades to improve powder properties (e.g., flowability and compressibility) for downstream processing. During this two-phase process that includes spraying and drying, the addition of a binder liquid causes primary particles to aggregate and form granules (1).
Description. Granulation and compression are two very important processes that are carried out extensively by most pharmaceutical companies. However, the theory of granulation is little understood and the selection of a particular machine and granulation method, is often done on the basis of tradition, rather than by using strict scientific or cost-benefit criteria.
Fluid Bed Granulation and Wurster Coating 33 Nozzles and Lances for Top-Spray Granulation 34 Nozzles for Wurster Coating 38. A fluidized bed occurs when a quantity of solid particles (generally contained in a holding vessel, most commonly a fluid bed …
Fluid bed granulation is a wet granulation process that involves the addition of a binder liquid to primary particles to form aggregated granulates. The material to be granulated is suspended within the fluid bed granulator by applying high-velocity air across the particles in order to set-up a fluidised bed …
Glatt Fluid Bed Dryer. ... Batch Fluid Bed Dryers "Used Glatt multi-cell type GMC-30 processing plant designed for granulation . Price: Please Inquire. Condition: Used. Batch Fluid Bed Dryers "Used Glatt GCPG 5 fluid bed coater. Includes 7″ Wurster and 9″ W. Price: Please Inquire.
Fluidized-bed granulators have a similar design and operation to fluidized-bed dryers. The powder particles are fluidized in a stream of air, but in addition granulation fluid is sprayed from a nozzle to the bed of powder. Granulating fluid is heated and filtered air is blown or sucked into the bed of unmixed powder to fluidize the particles and mix the powder; fluidization is actually a very ...
Fluidized bed granulator is one of the commonly used processing equipment in the pharmaceutical industries.It is a multi-purpose equipment in that mixing, granulation and drying are all carried out in the same equipment.
Glatt has shaped and constantly further developed this technology. Initially used solely as a dryer, the fluid bed unit has – by using suitable spraying systems – become a granulator and then – with the relevant developments – a particle coater. Today, fluid bed units are available for batch as well as for continuous production.
Fluidized bed dryer (FBD) is well known and widely used equipment in granulation area of pharmaceutical manufacturing. It is used in the granulation process for drying the material to get desired moisture content in the tablet formulation granules required for perfect compression of tablets.
Sep 27, 2013· Further information on Top-Spray granulation may be found at ... Glatt HP Process for granulation and coating by fluidized bed - Duration: ... Granulation Fluid Bed Drier1 ...

Fluid-bed spray-drying also offers lower operating costs and shorter process limes compared with freeze-drying. Tangential Spray Fluid Bed Granulation The second fluid-bed technique for wet granulation is the tangential-spray (rotary) process, available since the early 1980s (Fig. 2) which depicts a tangential-spray processor.
