<p>A heating type drying apparatus removes a trace amount of water contained in a synthetic resin raw material by evaporation. A direct heating type drying apparatus for a synthetic resin raw material includes a high-frequency induction heating section provided on a side surface portion of a dryer which also serves as a chamber for storing a synthetic resin raw material. The apparatus completely dries the raw material in a moment by means of an ultrashort wave electric field.</p> |
