High speed centrifugal spray dryer
Spray drying is a widely used process in the forming and drying industry of liquid process. SprayDrying BoxIt is more suitable for producing powdery and granular solid products from solution, emulsion, suspension and paste liquid raw materials. Therefore, spray drying is an ideal process when the particle size distribution, residual moisture content, stacking density and particle shape of the product need to meet the precise standard.
Second, the working principle
The air is filtered and heated into the air distributor at the top of the dryer, and the hot air enters the drying chamber in a helical and uniform manner. A high-speed centrifugal nebulizer at the top of the tower, (rotated) spray into a very slender foggy liquid bead, with hot air and flow touch in a very short period of time can be dried into a product. The product is continuously output from the bottom of the drying tower and the cyclone separator, and the exhaust gas is emptied by the fan.
Third, the performance characteristics
1, drying speed, material liquid after atomization of the surface area greatly increased, in the hot air airflow, instantly can transpiration 95%-98% of the water, complete the drying time only a few seconds, especially suitable for the drying of thermal sensitive materials.
2, the product has outstanding uniformity, fluidity and solubility, high purity of the product, good quality.
3, the production process is simplified, easy to operate and control. About the moisture content of 40-60% (special materials up to 90%) liquid can be dried into powder products at once, after drying does not need to destroy and select, reduce the production process, improve product purity. On the product particle size, pine density, moisture, in a certain range can be adjusted by changing operating conditions, control and management are very convenient.
