What is the core principle of spray dryer equipment?

In many of the spray drying equipment, drying equipment, drying equipment is one of the widely used, is drying equipment processing solution, suspension or slurry material. From liquid direct drying into powder, which is the biggest advantage of spray drying equipment; low heat efficiency, large volume, low production capacity, high investment is its disadvantages. Spray drying due to special advantages which can be directly from the solution or suspension system to obtain powder uniform components, is widely used in chemical industry, light industry, food industry, chemical industry is widely used in dye industry.

The working principle of the spray drying equipment: spray method is the material sprayed droplet dispersion in the hot air, and hot air is material and flow, countercurrent or mixed mode of contact with each other, so that the rapid evaporation of water, achieve the purpose of drying.

By adopting the spray drying equipment drying method, can save concentration, filtering, grinding unit operation, granular products can be 30~500 M. And short drying time, drying time for general 5~30s. Spray dryer is suitable for high sensitive material and the material liquid in the process of concentration is easy to disperse the drying of materials, products, good fluidity and instant.
