Profile: Mitchell Dryers Ltd. specializes in industrial drying machines. Our products include thermo Venturi dryers, band dryers, roller extruders, rotary dryers, calciners, sludge dryers, fluid bed dryers, stoves & cabinets, vacuum dryers, and intensive mixers. Thermo venturi dryers (also known as flash dryers or pneumatic dryers) are supplied for continuous drying of powders and granules which can be readily dispersed and conveyed in a hot air stream. The wet material is fed into the base of a vertical drying duct, dispersed in a high velocity air-stream, dried, and simultaneously conveyed to product collection. Material residence times are no more than a few seconds. This, together with the rapid evaporation, keeps the product cool enabling thermo-sensitive materials to be handled at elevated temperatures, and provides a very efficient system with low operating costs. Hot air is supplied into the base of the drying column. The heating and the inclusion of suitable pre-treatment equipment, together with recycling of the product, enables more difficult materials to be handled including some liquids. Fluid-bed dryer is based upon the plug flow principle, operating just below product fluidizing velocity.
