Zusammenfassung:To provide a drying system capable of preventing a wrinkle from being formed on a substrate when a coating film is heated.SOLUTION: The drying system disposed on a transfer route of a substrate transferred by a roll-to-roll method to dry a coating film coated on the substrate while transferring the substrate, comprises a heating unit for heating the coating film coated on the substrate and evaporating a solvent contained in the coating film and moisture adjustment means of adjusting the amount of a solvent contained in the coating film. The moisture adjustment means adjusts the amount of the solvent contained in the coating film present on the substrate to be a specified amount when the substrate being transferred at least passes through the heating unit and contacts a first transfer roll that contacts the substrate first at a specified wrap angle.SELECTED DRAWING: Figure 1 【課題】塗膜を加熱しても基材に皺が生じることを防ぐことができる乾燥システムを提供することを目的としている。【解決手段】ロールツーロールにより搬送する基材の搬送経路上に設けられ、基材を搬送しながら基材に塗布された塗膜を乾燥させる乾燥システムであって、基材に塗布された塗膜を加熱し、塗膜に含まれる溶媒を気化させる加熱部と、塗膜に含まれる溶媒の量を調節する調湿手段と、を備えており、前記調湿手段は、少なくとも搬送される基材が前記加熱部を通過して最初に所定の抱き角をもって接触する第1の搬送ロールと接触するときに、基材上の塗膜に含まれる溶媒が所定量になるよう調節する構成とする。【選択図】図1
