<p>The present invention concerns a method and a device for drying moisture-containing objects using microwave energy. The aim of the present invention is to gain full control over the drying process in a tunnel dryer and also to optimize the process so that the drying takes place as quickly as possible without the material being damaged. According to the invention, a step-by-step treatment of the material to be dried is achieved in a particular way. The drying equipment is built up of the required number of standardised modules (1, 2, 3), each of which is provided with one or more energy generators (8, 9, 10). Two adjacent modules are joined by means of a reconditioning part (4, 5), the length of which is adapted to suit the requirements of the process. In immediate connection with the outlet from each drying module certain parameters related to the drying are measured in the objects being dried. These parameters can be, for example, surface temperature and moisture content. Both the energy supply in one or more drying modules and the conditions in the reconditioning module can be adjusted with the aid of these parameters.</p> |
