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.
