Zusammenfassung: | PURPOSE:To avoid uneven drying and dry the coating applied to furniture at a low temp. by providing a plurality of far infrared drying processes wherein an air stream is produced transversely to he longitudinal direction of hollow parts along the inner peripheral surfaces thereof and an air cooling process continuously extending from the aforesaid drying process at an exit side. CONSTITUTION:The four units A, B, C and D adapted for the respective functions of preliminary drying, intermediate drying, finish drying and cooling are provided in a consecutive series, the hollow parts 12a-d provided in their respective units are arranged into the form of a continuous tunnel and a belt conveyor 26 is provided extending throughout the hollow parts 12a-d to form a drying device. A coated furniture is loaded on the belt conveyor 26 at an entrance of this device and the coating material thereon is dried being subjected to the temp. gradient set by far infrared heaters 16a-c in the cource of passage of the furniture from the preliminary drying unit A to the finish drying unit C. In a plurality of the processes of drying the coating material, blowers 18a-c produce an air stream transversely to the longitudinal direction of the hollow parts 10a-c along the inner peripheral surfaces thereof and the temp. of the interior of the hollow parts 10a-c is made uniform, in which condition the coating material is dried by far infrared rays. |
