Abstract
A method for drying building material slabs, in particular slabs containing gypsum, which are guided in floors (15) through an device divided into a drying pre-zone (2) and drying chambers and in which the slabs are brought into contact with drying air, characterized in that drying air is applied from the drying pre-zone (2) to the slabs in an area (1) arranged upstream of the pre-zone (2) and enclosed at least, with respect to the conveying direction of the boards, on both longitudinal sides and on the upper side.
Claims17
A device for drying building material slabs with drying air, wherein the device comprises floors and is divided into (1) a preliminary drying zone, (2) drying chambers, and (3) an enclosed area which precedes the preliminary drying zone and in which drying air from the preliminary drying zone is applied to the slabs which are in a final phase of a curing process to complete the curing process of the slabs in the enclosed area, and wherein in the enclosed area (i) a negative pressure of 50 Pa or less is generated, (ii) a moisture content of the drying air is controlled to a value of less than 30 g per kilogram of air and (iii) a temperature of the drying air is maintained at a value of from 35° C. to 60° C.
