products descriptions
Spray drying is the most widely used process in the liquid process
forming and drying industry. Ideal for producing powdered, granular
solid products from solutions, emulsions, suspensions, and pasty
liquid raw materials. Therefore, spray drying is an ideal process
when the particle size distribution, residual moisture content,
bulk density and particle shape of the finished product must meet
precise criteria.
products principle
Hot air enters into dryer in spiral form under
the function of air distributor after being filtered and heated. By
passing through high-speed rotary atomizer on top of tower, the
liquid raw material will be sprayed into the extremely fine mist
beads. Through the very short time of contacting with hot air, the
liquid can be dried into final solid powder products. The final
products will be discharged continuously from the bottom of drying
tower and from cyclone separator. Waste tail air will be discharged
from exhaust fan.
products Features
1. High speed drying. After liquid raw
material being sprayed, its’ surface area will be increased
greatly. With higher drying efficiency, 95%-98% of water could be
evaporated in a few seconds. Drying time is very short, it is
suitable for heat sensitive raw material
2. Product comes from spray dryer has very good uniformity, solubility, fluidity and purity.
3. The production procedures are simple, the operation and control are easy. Liquid with the moisture contents ranges 40-60% (for some special materials, the moisture content is available at 90%) can be dried into the powder in one time. There is no need for grinding or sieving after spray drying, this simplifies operation procedures and improves product purity. Product size, bulk density, moisture content is adjustable in certain ranges.
