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.
