出口10から噴出され、ホッパー１内を上昇して熱風排出
口19より排出される。The hot air is ejected from the hot air ejection port 9 and the hot air ejection port 10 through the hot air supply pipe 8, rises in the hopper 1, and is ejected from the hot air ejection port 19.
合成樹脂材料は、攪拌されつつ、上昇熱風によって乾燥
され、排出口６より排出される。The synthetic resin material is dried by rising hot air while being stirred, and is discharged from the discharge port 6.
なお、被乾燥物は、合成樹脂材料に限定されるものでな
いことは云うまでもない。Needless to say, the material to be dried is not limited to the synthetic resin material.
（発明の効果） この発明は前記した如き構成によって以下の如き効果を
