Abstract: PURPOSE: A spray drying system improves drying performance without damaging dried material. CONSTITUTION: A spray drying system comprises a reactor(1), a dryer(4), a pump, an air compressor(2), a heater(3), a cyclone(5) and a low pressure nozzle(6). The reactor(1) makes sample to be sprayed react. The dryer(4) sprays the sample and dries. The pump is placed between the reactor(1) and the dryer(4) to deliver the drying sample of the reactor(1) to the dryer(4). The air compressor(2) compresses air supplied to the dryer(4). The heater(3) supplies hot air used for drying the sample to be sprayed. The cyclone(5) is fixed on one side of the dryer(4) to buffer. The low pressure nozzle(6) sprays the sample to the upper end of the dryer(4).
