LPG Series High-Speed Centrifugal Spray Dryer With Big Valume
Descriptions
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.

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.
Points:
1. The contact with the hot air droplets: a sufficient amount of hot air entering Spray drying chamber must be considered hot gas flow direction and angle, and whether it is flow, countercurrent or mixed flow, to ensure full contact with the droplet can be sufficient heat exchange.
2. Spray: Spray Dryer atomizer system must ensure a uniform droplet size distribution, which is essential. Because in order to ensure that the passing rate of product quality.
3. And the angle of the cone angle of the pipeline design: We get some empirical data from the production of nearly a thousand units Spray Dryer group, and we can share.
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.

Brief
Spray Dryer, Spray drying tower is liquid forming process and drying process industry is the most widely used. Most suitable for the production of powder from suspension emulsions, solutions, emulsions and paste liquid, granular solid product. Thus, when the finished product particle size distribution, residual moisture content, bulk density and particle shape are in line with the precision standard, Spray Dryer is ideal for drying process.
