Abstract (en)
[origin: WO2019106615A1] A drying plant (1) for drying pretreated flexible sheet products, having at least one side on which a layer of a chemical compound has previously been deposited, said system (1) comprising feeding means (2) for feeding the sheet products in a direction (L), drying means (3) for drying the products as they are being fed, which have at least open operating unit (5) with a chamber (6) through which the feeding means (2) are designed to pass, and with at least one applicator (10) connected to a respective generator (11) for application of an alternating electromagnetic field in the RF range and a control unit (1 6), for controlling the generator (11) and/or the applicator (10). The field has an oscillation frequency that ranges from 300 kHz to 300MHz and is preferably 27.12 MHz at least one air blowing means (18) (18) for delivering hot air and/or at least one suction means (19) are provided. The control unit (16) is configured to change the speed of the feeding means (2) or to change the electromagnetic field application time. Sensor means are further provided, for detecting one or more physical and/or thermodynamic parameters of the operating unit (5) and the temperature of the sheet and for controlling the means (2, 18, 19) separately from or in combination with each other and carry out complete drying of the chemical compound layer.
