LPG-50 High Speed Centrifugal Spray Drying Machine
LPG-50 High Speed Centrifugal Spray Drying Machine
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.
Machine Structure Consist：
This procession equipment includes five different structures: Feeding System, Heating System, and Drying System, collecting system and electronic controlling system.
（a）、Feeding System：
Morrow pump is adopted on feeding pump which speed can be adjusted. It meets to the special requirement from Starting Temp increasing, Stop Temp decreasing and stable material feeding when machine running.
The speed of the Nebulizer can be reached higher than 120m/s by two grades motor transport with two grades gear speed up. It can atomize raw material fast, continuously and uniform. The surface area of granule increased and exchange heating with clean hot air, and the moisture took away by induce draft fan.
（b）、Heating System：
The hot air use to drying is filtered clean air. The first filter is non-woven special for prevent bugs fly into drying tower. The second filter us also made from non-woven, filter accuracy is less than 5micron. The resistance of second filter is ≤15mmH2O. It is special for filter dust in the air to prevent to pollute products. The third filter reaches 100,000class clean.
The heating processing adopts Steam heating with electronic heating(36KW) compensate.
（c）、Drying Station：
The drying station consist by Hot Air Volute, Hot air distributor, inner tower, Tower structure, Outer Tower, Material discharge pipe, heat preservation materials, cleaning door and light hole. The cleaned hot air come out from heating device goes through hot air volute to hot air distributor then goes to drying tower uniformly. The rotation position of hot air distributor can be adjusted from 0 degrees to 30degrees.
There is one View and clean door equipped on drying tower, the light is equipped on the top of the inner tower for lightening whole tower. The heating preservation materials are made from aluminum silicate with 60mm thickness.
（d）、Collecting System：
The collecting system consist by First grade separator and second grade separator. It can collect 93-97% powders, the others will be collected by dedustor. The discharge style is vacuum valve discharge.
