Working principle of centrifugal granulating spray dryer
2022/1/20 10:18:42
Centrifugal granulator spray dryer principle: hot air enters the nozzle at the appropriate spouting speed, and enters the drying chamber from the top of the centrifugal granulation spray drying machine, which produces mass transfer and heat transfer to the material. At the bottom of the dryer, the particles with low moisture content and small particle size are entrained and raised by the rotating air flow, and further dried in the rising process. Due to the rotating flow of gas-solid two phases, the inertia of solid phase is greater than that of gas phase, and the relative velocity of solid-gas two phases is larger, which strengthens the mass transfer and heat transfer between the two phases.
