LPG High Speed Centrifugal Spray Dryer

Product description
  Spray drying is a process liquid process shaping and drying industry is the most widely used. Ideal for generating powdery, granular solid product from the solution, emulsions, suspensions and pasty liquid feedstock. Thus, when the finished product particle size distribution, residual moisture content, bulk density and particle shape must meet the precision standard, the spray drying is an ideal process.
Working principle

  Heated air through a filter and into the top of the drier air distributor, the hot air was uniformly into the drying room in the spiral. Passing through the top of the tower high-speed centrifugal atomizer (rotary) sprayed into the extremely fine mist liquid beads in contact with the hot air stream and in a very short period of time can be dried into a finished product. Finished continuously from the bottom of the drying tower and cyclone exhaust gases vented by the fan.

◎ drying speed, greatly increasing the surface area of the material after the liquid is atomized in a stream of hot air, it can instantly evaporate 95% -98% of water to complete the drying time of just a few seconds, especially suitable for drying heat sensitive materials.
◎ product has a good uniformity, mobility and solubility, high purity and good quality.
◎ 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.
