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.

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. Safety.
Because of flammable and combustible dangerous of organic solvent, this machine take Safety technologys including on-line Oxygen checking, explosion-proof, Explosion venting and so on. Through intelligentized control technology, to monitor Oxygen residues/Pressure balance in the system and automatic modulation control. When air(oxygen) content exceed 0.5%(v/v),oxygen checking device open the Replenishing valve to supply fresh nitrogen by control system, to recovery the oxygen residues to a safety value(closed-circuit system is designed into positive pressure,oxygen entry into circulation system by material feeding).When air pressure inside the system exceed setted value(air pressure balance is setted into 0.02mpa),explosion venting device will automatically open decompression Pneumatic valve to exhaust some air by intelligentized control .The explosion-proof and explosion venting system is another safety technology of this machine, that is when certain electrical equipment or key device damaged, the system is out of normal working and air pressure up to safety ultimate value(≤0.05Mpa),explosion-proof and explosion venting system will be automatically opened, power cutted off and pipe valve closed, there is no probability of solvent reacting with oxygen,which avoid fire damagesor explosion during machine working.to make sure safety production.
3. Saving energy.
This machine is full closed system. Hot air through net board blow up the material. Hot air contact with material fully. The process of heat transfer is enhanced. At a Few air condition, a high air moisture can be got, so Only Micro positive pressure during working, needed air quantity is small. Fan power of this machine is smaller and less noise. At the meantime,
Hot air with solvent after drying is separated by condensator. The recoveryed solvent can be reused. So saving energy and production cost. Also, Low dew point nitrogen is sent to air heater for cyclic utilization by fan. Compared with common dryer, thermal efficiency enhanced, power consumption reduced, so heat consumption and production cost saved.
4.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.
