Spray dryer YPG

hot airairnozzle

Principle The air enters into the top of the dryer after been filtered and heated, the material liquid be pumped to the top of the tower by high pressure pump, the feeding solution becomes fine beads or small droplets through the pressure nozzle. When the hot air contacts with the droplets, the temperature of air declines significantly, the humidity of air increases greatly, and then the air will be exhausted by exhaust fan. The fine powder in the air will be collected through different separating devices ,There’re different fine powder separation and recovery devices, such as cyclone, bag filter, cyclone + bag filter, cyclone + water scrubber, and cyclone + bag filter + water scrubber etc. we will supply the different fine powder separation and recovery devices as per the characteristics of product and requirements of customer. Depend on the product features and requirements, we might install secondary drying and cooling system (such as ZLG vibration fluid bed or pneumatic transportation), formulation system or powder sieving system etc after the spray dryer, or dehumidifier. The particle size of the product from pressure spray dryer is normally within the range of 120mesh to 40 mesh. Features 1. The drying speed is high, 95%-98% of water can be evaporated at a moment . The time of completing the drying is only several seconds. This is especially suitable for drying the heat sensitive materials. 2. The final products have good uniformity, flow ability & solubility. And the final products are high in purity and good in quality.
