Spray drying is a most widely used craft in liquid molding process and drying industry. LPG high speed centrifugal spray dryer equipment is ideal for producing powdery and granular solid product from the solution, emulsions, soliquoid and pumpable paste states. Thus, when the particle size distribution, residual moisture content, bulk density and particle shape must meet a precision standard, the spray drying is an ideal choice.
Main Features
1.Fast drying speed; LPG high speed centrifugal spray dryer greatly increasing the surface area of the material after the liquid is atomized; it can instantly evaporate 95% -98% of water in the stream of hot air; it takes only a few seconds to complete drying, which is especially suitable for drying heat sensitive materials.
2. Our products have a good uniformity, mobility and solubility, high purity and good quality.
3. Simplified production process, easy to operate and control. Liquid of 40-60% moisture content (up to 90% for special materials) can be dried into powder products at a time, without crushing and screening after drying, which reduces production process and improve product purity. The size, bulk density, moisture can be adjusted within a certain range by changing operation conditions. It is convenient to do control and management.
