24-09-2013· A spray dryer uses the spray method to transform the material into fog droplets in order to be dispersed into the hot gas stream. The material connects with the hot air in a cocurrent, countercurrent, or mixed flow manner so that the water can evaporate quickly to achieve the drying effect. HOW DOES IT WORK? 3. Chemical Industry Petroleum Industry Mining Industry INDUSTRIES USING SPRAY DRYERS …

Spray drying is the process of transforming a liquid into a dry, particulate solid by atomizing the liquid and bringing the liquid in contact with a hot gas. Such a process may be achieved in a spray drying chamber. Spray dryers are extensively used in many industries such as the food industry to dry the liquid feed when close control over the product size distribution is needed.
