Abstract
Method and device of automatically controlling the drying process of a laundry drying system until a given desired degree of dryness is reached, including heating means, a drive for the drying system, a control device for controlling the drive and heating means, and means for supplying system-related fixed data concerning the drying of particular laundry, which includes determining the gradient of rising temperature in the drying system during a given early phase of the drying process, calculating a required operating time for the heating means and the drive from the determined gradient and the system-related fixed data, and feeding the calculated operating time as an input to the control device.
