WHAT IS FLUID BED DRYING? By forcing enough gas (air) through a bed of particles, the bed may assume a fluid-like state (resembling a boiling liquid). Heating the incoming air and managing air flow rate through the Model 501 provides thorough mixing and maximum contact of solid with moving air. The result; a process more even and much quicker than conventional drying methods. FAST Delivering up to 2.5m3 per minute of air, the model 501 can break up wet samples, and ensure vigorous mixing and rapid moisture removal. 5 kg of wet “ideal” sample (80% moisture) can be dried in 15 - 20 minutes (5...

SHERWOOD SCIENTIFIC FLUID BED DRYER FLUID BED DRYERSPECIFYING PROCESS SAMPLE TYPE SYSTEM “REQUIREMENTS” Simple dryer The Sherwood Scientific Model 501 Fluid Bed Dryer is a Lab Scale (Bench Top) dryer with a maximum sample capacity of 5Kg. There is a wide variety of drying tubs (volume and material of construction), inlet & outlet filters, and other accessories available; both to handle as wide a range of sample types as possible and enhance the capability of the drying system. Therefore each system requires specifying in some detail to reflect individual customer requirements and sample...

SHERWOOD SCIENTIFIC FLUID BED DRYER THE BASIC DESIGN The basic Model 501 incorporates an air pump, heating coil, and temperature measurement (with control and timer). Air is drawn through an inlet filter, passed over a heating element and forced through a support filter (which holds the weight of the sample) and a Tub inlet filter (selected for pores smaller than the sample particle size). The air passes through the sample contained within a tub (glass or stainless), and finally through an Outlet filter which can be a Filter Bag. Bag material is selected to be chemically inert to emitted...

Sherwood Fluid Bed Dryers have been used on hundreds of different sample drying applications, from 10 gms to 5 Kgs. In addition, they have been used to mix solids, form uniform coatings, determine drying parameters, analyse for moisture by weight loss, form fine granular particles from agglomerates, act as a chemical reactor, and classify (separate) particulates by density, size, and surface texture. If your particular drying application is not listed please contact; info@sherwood-scientific.com Substances take up water in two ways External moisture is on the surface of particles and...

SHERWOOD SCIENTIFIC FLUID BED DRYER WHAT IS FLUID BED DRYING? Drying curves were traditionally generated by sequential weighing over time periodically interrupting the drying process. Using all the features of the 501 fluid bed dryer i.e. in-tub temperature /humidity probe & software, all data can be logged and stored for future reference and subsequent manipulation. Raw data can be manipulated using software to produce drying curves. Inlet air temperature, blower motor speed, in-tub temperature and relative humidity can all be recorded against time (using software and the temperature...
