Pharmaceutical Dryers Centrifugal Industrial Powder Spray Drying Machine
Product description of Spray Dryer
High Speed Spray drying Machine is a 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.
Atomizer is the most important accessory in spray drying machine, it is used for changing LIQUID status into SPRAY status at a high speed rotation motions, usually can reach 18000~25000 rpm.

Main Features of Spray Dryer
The drying speed is high when the material liquid is atomized , the surface area of the material will increase greatly .In the hot-air flow,95%-98% of water can be evaporated within only seconds.More suitable for drying the heat sensitive materials.Spray Drying Machine final products own the advantages of good uniformity, flow ability & solubility. Also high in purity and good in quality.
The production procedures are simple and the operation and control are easy .The liquid with moisture contents of 40-60% (for special materials, the contents might be up to 90 %.) can be dried into the powder or particle products once a time.
After the drying process, there is no need for smashing and sorting, so as to reduce the operation procedures in the production and to enhance the product purity .The product particle diameters, looseness and water contents can be adjusted through changing the operation condition within a certain range. It is very convenient to carry out control and management.
Application advantages
1. The drying speed is fast, and the surface of the material liquid
is greatly increased after atomization. In the hot air flow,
95%-98% of the water can be evaporated instantly, and it only takes
ten to ten seconds to complete the drying step. Suitable for drying
heat-sensitive materials;
2. The products obtained by drying are spherical particles with
uniform particles, good fluidity, good solubility, high product
purity and good quality;
3. Wide range of applications, users can choose to use hot air
drying and cold air granulation according to the characteristics of
the material, which has strong adaptability to the material.
4. The operation is simple and stable, the control is convenient, and it is easy to realize automatic operation.
