METHOD AND DEVICE FOR DRYING AND/OR ROASTING A FOOD

The invention relates to a method for drying and/or roasting a food which is perfo1med in a treatment apparatus (2), comprising a treatment chamber (3) and at least one heating apparatus (4). The method comprises the step of heating a gas by means of the heating apparatus (4). A further step comprises heating an outside (5) of the treatment chamber (3) and in particular conducting part or all of the heated gas through the treatment chamber, wherein the heated gas can be conducted through the treatment chamber (3) before the heating, after the heating, or simultaneously with the heating of the outside (5). The food in the treatment chamber (3) is dried and/or roasted due to the heating and/or by means of the heated gas conducted through the treatment chamber. During the drying and/or roasting, a control value in the treatment chamber (3) is determined on the basis of a measured value of a sensor. The heating and/or the conducting of heated gas through the treatment chamber is controlled in dependence on the determined control value, in particular the moisture.
