Abstract
A flash drying apparatus has a vertical, cylindrical enclosure. In a lower portion of this enclosure is disposed a rotating disk. Above this disk is provided a crusher that, using blades formed radially thereon, crushes a raw material into a powdery or granular material. The crusher is provided with a material feeder that feeds the raw material to the crusher by letting the raw material fall onto the crusher. A hot wind feeder feeds a hot wind to the powdery or granular material from under the blades. The powdery or granular material blown upward inside the enclosure by the hot wind is exhausted through an exhaust duct provided in an upper portion of the enclosure. This flash drying apparatus prevents degradation in performance resulting from deposition of a raw material.
