BLGZ Series Closed-loop Circuit Fluid Bed Dryer is 1.mainly used for solvent recovery and drying of material with solvent.2.For Drying of materail with solvent from sway granulator and high-speed Mixing granulator.3.For drying of wet granules and powder with solvent in foodstuff,chemical industry,pharmaceutical industry and so on.4.For drying or large granules,small blocks and Low-viscosity material.
Working Princple
Take nitrogen as medium for heat transfer ,to realize solvent recovery and drying of material with solvent ,with features of safety , high efficiency ,Low energy consumption and so on . Air under the circulation function of fan ( both blower fan and suction fan ), after heated by steam radiator and filtrated by HEPA filter , entry into fluid bed dryer to dry the material . At the meantime , under the continuous stirring inside the dryer , hot air and raw Material exchange their heat fully . After solvent ( alcohol , acetone , methanol and so on ) steamed out , fine powder together with circulating gas come out , finepowdercaughtby nitrogen blowback system . Waste - heat air after filtrated by filter entry into compensator , solvent is cooled to dew point and separated from air , so solvent recycled . Separated air is fed into air heater by fan , go round and begin again like this .. Untilallsolventissteamedout , separate and recovered . After drying , products are discharged from the bottom of the dryer , net plate for material is flexible reverse turning bed and controlled by cylinder . After all products discharged , fan can clean the air filter inside the dryer
