|Applicants:||TAIHEI MACHINERY WORKS, LTD.
|Title:||MULTI-STAGE DRYING APPARATUS AND MULTI-STAGE DRYING METHOD FOR PLATE MATERIALS TO BE TREATED|
A horizontal type multi-stage press apparatus 1 (a multi-stage drying apparatus) is provided with conveyance routes R1 to R4 (first to fourth conveyance routes) on which a single plate W1 (a plate material to be treated) in a standing state is conveyed. The conveyance route R1 is disposed across a loader device 10 and a hot press device 20, the conveyance route R2 is disposed across the hot press device 20 and an open evaporation device 40, the conveyance route R3 is disposed across the open evaporation device 40 and a temperature adjusting press device 50, and the conveyance route R4 is disposed across the temperature adjusting press device 50 and an unloader device 60. The conveyance routes R1 to R4 are arranged in one straight line in a plan view. A plurality of the single plates W1 held by the open evaporation device 40 are set such that water vapor can be dissipated from both surfaces, in a standing state, of each of the single plates W1. The finishing temperature of each of the single plates W1 is maintained at a desired temperature by the temperature adjusting press device 50. Accordingly, a multi-stage drying apparatus and a multi-stage drying method for plate materials to be treated are provided in which a single plate having a certain quality can be produced while a space occupied by the entire apparatus is reduced.
