Spray Drying Equipment
1.Introduction
LPG Series High Speed Centrifugal Spray Dryer 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.
2.Feature
1、Spray drying speed, when the material liquid is atomized, the surface area increased significantly, with the hot air in contact with the process, the moment can be 95% -98% moisture evaporation, drying time of just a few seconds, especially for heat-sensitive materials dry.
2、The product has a good uniformity, higher fluidity and solubility, purity and good quality.
3、Spray Dryer production process is simplified, easy to operate controls. For moisture content of 40-60% (for special materials, up to 90%) of the liquid can be dried into a powder product, after drying without crushing and screening to reduce the production processes, improve product purity. For the size, bulk density, moisture, within a certain range can be adjusted by changing the operating conditions, the control and management is very convenient.
