DetailProduct overview ：
Spray drying is the most widely used in the liquid technology shaping and drying industry process. Apply to most from solution, emulsion, suspending liquid and plasticity paste liquid raw materials generated in the powder, granule or block solid product. Therefore, when the particle size distribution of the final products, their residual water content, bulk density and particle shape must meet the precision standard. The spray drying is one of the ideal process.
The working principle of ：
After filtering and heating, air into the dryer at the top of the air distributor, hot air spiraling evenly into the drying chamber. Material liquid via high-speed centrifugal atomizer, on top of the tower body (rotating) into a very fine mist spray liquid bead, contact with the hot air flow in a very short period of time can be dry as finished products. Finished product continuously by the LPG series high speed centrifugal spray drier dry bottom and the output of the cyclone separator, exhaust fan by emptying.
Product features ：
Fast drying speed, significantly increased after spraying the surface area of material liquid, in the hot air flow, instantaneous evaporation can be 95% - 98% of moisture, drying time only for a few seconds, especially suitable for drying of thermal sensitive material.
LPG series high-speed centrifugal spray drying machine products has good uniformity, fluidity and solubility, high purity and good quality.
Production process is simple, convenient operation and control. Special material for 40-60% moisture content (up to 90%) of liquid to a dry powder products, dried without crushing and screening, reduce the production process, improve product purity. The product particle size, bulk density, moisture, within a certain range can be adjusted by changing the operating conditions, control and management are very convenient.
Range of application：
* Chemical industry: sodium fluoride (potassium), alkaline dyestuff pigment, dyestuff intermediate, compound fertilizer, formaldehyde silicic acid, catalyst, sulphuric acid agent, amino acid, white carbon black, etc.
