Bag Filter Pharmaceutical Fluid Bed Dryer

BLGZ Series Closed Circuit Fluid Bed Dryer with nitrogen protection

Applications

1. BLGZ Series Closed Circuit Fluid Bed Dryer with nitrogen protection is mainly used for solvent recover and drying of material with solvent.

2. For drying of material with solvent from Sway Granulator and high-speed mixing granulator.

3. For drying of wet granules and powder granules with solvent in food stuff, chemical industry,    pharmaceutical industry and so on.

4. For drying of large granules, small blocks and Low-viscosity material.

Working principle

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 of stirring system 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, fine powder caught by 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..Until all solvent is steamed out, 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.

Features and Advantage.

1. High efficiency.

2. Safety.

3. Saving energy.

4. Environmental protection.
