ABSTRACT:
To secure a desired value, preferably adjustable in advance, of the moisture content at the end of the drying process, independent of the amount of articles to be dried and of the material of these articles, a tumbler dryer may be provided with a temperature sensor (G) which senses the temperature (T) of the exhaust air from the drum (TR). The tumbler dryer is provided with control members (S) which determine the value of the temperature at the time when the rate of increase of the temperature during the latter stage of the drying process starts increasing, and which terminates the supply of hot air to the drum when the temperature has risen by a preset amount, corresponding to the desired moisture content, above said value. (FIG. 1.)
