LPG Series High-Speed Centrifugal Spray Dryer
Working Principle
Spray Dryer for the open cycle and flow, centrifugal atomization. After air drying medium early, medium efficiency air filters and filtered according to the operating instructions by the draw and then heated by the heater blower high efficient filter through into the hot air dispenser spray drying the main tower. After the liquid material in accordance with an operation instruction peristaltic pump, atomizer into the high-speed rotation, the centrifugal force is dispersed into small droplets. In Spray drying main tower with hot air in small droplets full contact drying by heat exchange with a product along a particular path, then through a cyclone to achieve separation, the solid material is collected, filtered and then the gaseous medium, and then discharged. Spray the entire system easy to clean, no dead ends, in line with GMP requirements.

LPG Series High-Speed Centrifugal Spray Dryer
The Spray drying is the technology most widely used in the liquid technology shaping and in the drying industry. The drying technology is most suitable for producing solid powder or particle products from liquid materials, such as: solution, emulsion, suspension and pumpable paste states, for this reason, when the particle size and distribution of the final products, residual water contents, mass density and the particle shape must meet the precise standard, spray drying is one of the most desired technologies.
