Closed Loop 37 Kw Pharmaceutical Fluid Bed Dryer

explosion proof closed loop Circuit Fluid Bed Dryer with solvent recovery

Closed Loop Pharmaceutical Fluid Bed Dryer Explosion Proof With Solvent Recovery

Applications

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

2. 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

1.High efficiency.

This machine is fully enclosed structure, no dead corner, both air exhaust system and air in system takes high-temperature and high-efficiency filter. The whole system has 3 levels of dust catcher, with high-efficiency dust catcher, easy to discharge and clean. After drying finished, because of blowback system, dust elimination is more thoroughgoing, reducing cleaning frequency, which can reduce labor intensity and avoid pollution of different products, Low viscosity, meeting GMP standards.

This machine can work continuously and steady in a long term, high degree of automation. It not only can dry, cool solvent, but also can cool raw material, drying efficiency is higher than other dryer, 4 to 5 times drying speed. And, the finished products have good quantity, which can create bigger product value for the user.

According to the user’s requirement, vacuum feeder, vacuum discharger for optional, to enhance automatization degree.

2.Environmental protection.

This machine recovery the solvent from raw material during drying process based on solving the problem hard drying and Heavy pollution. At the meantime, zero exhaust avoid environmental pollution because of waste gas.
