Application Overview
Spray drying is widely used in liquid forming and drying industries. It is suitable for generating powdery and granular products from solutions, emulsion, suspensions and pumpable paste liquid raw materials. Therefore, spray drying is a very ideal process when the particle size distribution, residual moisture content, bulk density and particle shape of the finished product must meet accurate standards.
Equipment characteristics
★ The drying speed is fast, and the surface area of the liquid material greatly increases after atomization. In the hot air flow, 95% -98% of the water can be instantly evaporated, and the drying time is only about a few seconds. It is particularly suitable for drying heat-sensitive materials.
★ Compressed air atomization is particularly suitable for viscous objects.
★ The production process is simplified and the operation and control are convenient. Usually used for solutions with a moisture content of 40-60% (up to 90% for special materials), they can be dried into powder products in one go. After drying, there is no need for crushing and screening, reducing production processes and improving product purity. The product particle size, bulk density, and moisture can be adjusted within a certain range by changing operating conditions, simplifying the production process and making control and management very convenient.
