SHH-LPG Series Spray Dryer Centrifugal Drying Machine

SHH-LPG Series Spray Centrifugal Drying Machine

Description:

Spray drying process is the widest used in the liquid forming process and in drying industry. The drying technology is most suitable for powder, particle products from materials, such as,solution, emulsion, and pumpable paste states material. For this reason, when the particle size and distribution of the final product, their residual water contents, the stacking density and particle shape must meet the precision standard, spray drying process is one of the most desired processes.

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.

Features

1. Drying liquid or slurry materials into dry powder

2. Atomizing type: Rotary Atomizer & Pressure Nozzle

3. Evaporation Capacity: 1-5000kg/h

4. Heat source: steam, electricity, thermal oil or gas/oil/coal fired hot air generator

5. 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
6. Product comes from spray dryer has very good uniformity, solubility, fluidity and purity.
7. 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.
