一. Flash dryer working principle

Hot air from the inlet pipe at a suitable jet speed into the bottom of the dryer into the mixing crushing drying chamber, the material has a strong shear, blowing, rotating role, so the material by centrifugal, shear, collision, friction and be micronized , Enhanced mass and heat transfer. At the bottom of the drier, the larger and more wet granulation is mechanically crushed by the agitator. The lower the moisture content, the smaller granularity is entrained by the rotating airstream and further dried during ascent. As the gas-solid two-phase rotating flow, the solid phase inertia is greater than the gas phase, solid-gas relative speed between the two phases is larger, strengthening the heat and mass transfer between the two phases, so the machine high production intensity.

2, flash dryer features:
(1) Into the wind with dual air duct tangential air inlet to ensure dynamic balance into the wind, to avoid the accumulation of material.
(2) Set the water jacket, to eliminate the coking of heat-sensitive materials, discoloration.
(2) The main tower set swirl film effectively control the finished product final moisture and fineness.
(3) The drying air enters the bottom of the drying chamber to produce a strong swirling air flow, resulting in a strong erosion of the material on the wall to eliminate the sticking phenomenon.
(4) The material is discharged by a closed fan to prevent the accumulation of system material.
(5) The system negative pressure operation, inhibition of running, run, drip, leak.
(6) Set the sewage outlet for easy cleaning.
(7) The machine is equipped with a screw feeder, so that the material can be uniform, quantitative, continuous, stable added to the dryer.
(8) easy to replace the key components of the dryer, the key control parameters adjustable to adjust the material residence time, to meet the drying needs of more varieties of materials
