DRYER AND HEAT TREATMENT SYSTEM

PROBLEM TO BE SOLVED: To provide a dryer that can efficiently dry a coating film and a heat treatment system into which the dryer is incorporated.SOLUTION: In a drying section 40, lower hot air ejecting portions 51, upper hot air ejecting portions 45 and exhaust boxes 56 are provided on the inner side of a casing 41 having openings at both ends thereof. The plurality of lower hot air ejecting portions 51 are arranged on the lower side of a conveyance route of a base material 5, and the plurality of upper hot air ejecting portions 45 and the plurality of exhaust boxes 56 are alternately arranged on the upper side. The upper hot air ejecting portion 45 includes a straightening vane 43 and an ejecting head 46. The ejecting heads 46 and the lower hot air ejecting portions 51 are arranged to oppose to each other while sandwiching the conveyance route. The exhaust box 56 includes a suction port located at a lower end and extending in the width direction of the base material 5 to suck the atmosphere around the suction port. 【課題】塗布膜を効率良く乾燥させることができる乾燥装置および該乾燥装置を組み込んだ熱処理システムを提供する。【解決手段】乾燥部４０は、両端に開口が形成された筐体４１の内側に下側熱風噴出部５１、上側熱風噴出部４５および排気ボックス５６を備える。基材５の搬送経路の下側には複数の下側熱風噴出部５１が設けられ、上側には複数の上側熱風噴出部４５と複数の排気ボックス５６とが交互に設けられる。上側熱風噴出部４５は、整流板４３および噴出ヘッド４６を備える。噴出ヘッド４６と下側熱風噴出部５１とは搬送経路を挟んで相対向して配置されている。また、排気ボックス５６は、基材５の幅方向に沿って延びる吸引口を下端に備え、当該吸引口周辺の雰囲気を吸引する。【選択図】図５
