Voice Engineers offer excellently designed and fabricated vibratory fluid bed dryer for fluidization of materials which are often characterized by having one or more of the following physical properties :
In the vibratory fluid bed dryer, the material is easily transported through the dryer by the combined effects of fluidization and vibration. The fluidization velocity can be judiciously selected to minimize entertainment of the smaller particles, to avoid gas bubbling m the fluid bed thereby minimizing attrition. The residence time can be adjusted, by varying the bed height, through the overflow weir position. A cooling section can also be provided, by partitioning of the plenum chamber.
Vibratory Fluid bed dryers have a bed of solid particles, which are fluidized by passing a stream of air or gas upward through a specially designed perforated sheet. The upward velocity of air is so maintained so as to slightly lift the solid particles and set them in motion. This motion can be utilized to bring about mixing as well as forward movement of the solids. The air or the gas is heated and the heat is utilized to dry the solids. Fines get agglomerated to larger particles thus providing large size granules.

Spin Flash Dryers designed and manufactured by Voice Engineers is another system for solid fluidization. This dryer is useful for mechanical dispersion and for adjusting the granule size of high humidity paste type material.
Under the action of hot air and mechanical dispersion, the wet cake appears granular and gets fluidized. Instantaneous exchange of heat and mass takes place. The dried materials are taken in the collector as powder products.
The system consists of double shaft screw followed by mono screw to feed homogenized material into dryer housing at controlled rate. The tangential entry of air and mechanical action of agitator help to decompose lumps enabling intimate mixing of hot air with the product, and thus ensuring drying of the product. The particle classification orifice on the top of drying chamber allows finer product to pass with exhaust gas to powder collection system. The drier is useful for drying sticky products, also effective against viscous materials.
The simple Flash Dryer is designed lo handle materials that can be suspended directly in air, requiring removal of free moisture. Wet material is dispersed into a stream of heated air (or gas) which conveys it through a drying duct. Using the heat from the air stream, the material dries as it is conveyed. Drying takes place in a matter of seconds, and the final moisture is generally in the constant rate drying zone. Elevated drying temperatures can be used with many products since the flashing off of surface moisture instantly cools the drying gas without appreciably increasing the product temperature.
Voice Engineers is manufacturer and supplier of Spin Flash Dryer. Product is separated using cyclone, and/or bag filter. Typically, cyclones are followed by scrubbers or bag filters for final cleaning of the exhaust gases to meet current emission requirements.
