There are many types of spray drying equipment with a wide range of uses. It can be said that dryers are present in all aspects of life, especially in industrial production. The existence of dryers is inseparable. How is the specific dryer used in industry, that is, the role of the dryer in industrial production and Purpose, take spray dryer as an example.

According to the structure of the atomizer, drying equipment can be divided into three types: centrifugal spray drying equipment, pressure spray drying equipment and air flow spray drying equipment. Spray drying equipment is suitable for drying solutions, suspensions or slurry materials, especially highly heat-sensitive materials and materials that are easily dispersed during the liquid concentration process. It uses the spray method to turn the material into mist droplets, which are dispersed in the hot air. The material and the hot air flow in parallel, countercurrent or mixed flow, so that the water evaporates quickly to achieve the purpose of drying.

Spray drying is a method that applies system technology to material drying. The diluent is atomized in the drying chamber and when in contact with hot air, the water evaporates quickly to obtain a dry product. This method can directly dry solutions and emulsions into powder or granular products, thus saving evaporation, grinding and other processes.
