FIELD: heating system.
SUBSTANCE: druing unit has, at least, one nozzle for supplying the drying fluid to the web in such a way that the drying fluid with the excited vibrations is directed to the web, at least, one outlet device for moist air obtained during the convection drying, and a conveying means for moving the web relative to the drying unit. The drying unit has, at least, one ultrasonic generator that is located in the region of the nozzle to create oscillations of the drying fluid so that ultrasound can help to reduce the moisture content over the entire width of the web.
EFFECT: reduction of the moisture content in the web by means of convection drying.
