A flash dryer is a type of industrial equipment used to quickly dry materials, often in the form of powders or slurries. It works by rapidly heating the material with hot air, causing moisture to evaporate almost instantly. This process is efficient and helps preserve the quality of the product being dried. Flash dryers are commonly used in various industries, including food processing, pharmaceuticals, and chemicals. They can handle a wide range of materials, such as starch, milk powder, and ceramics. The design of a flash dryer allows for continuous operation, making it suitable for large-scale production.
