Abstract

Es handelt sich um einen Durchlaufofen (4) zur kontinuierlichen Erwärmung einer Pressgutmatte (1), insbesondere im Zuge der Herstellung von Holzwerkstoffplatten, mit einem tunnelförmigen Gehäuse (5), durch dessen Innenraum (7) die Pressgutmatte hindurchführbar ist und mit einem oder mehreren Mikrowellengeneratoren (6) zur Erzeugung von Mikrowellen, die über ein oder mehrere Hohlleiter (8) in den Innenraum (7) des Gehäuses einstrahlbar sind. Der Ofen ist dadurch gekennzeichnet, dass die Hohlleiter (8) zumindest abschnittsweise als Hohlleiter-Schlitzantennen (8a) ausgebildet sind, die jeweils mehrere Austrittsschlitze (9) für die Einkopplung der Mikrowellen in den Innenraum (7) aufweisen.

Figure imgaf001
It is a continuous furnace (4) for continuously heating a pressed material mat (1), in particular in the course of the production of wood-based panels, with a tunnel-shaped housing (5), through the interior (7) of the pressed material mat can be passed and with one or more microwave generators (6) for generating microwaves, which can be irradiated via one or more waveguides (8) in the interior (7) of the housing. The furnace is characterized in that the waveguides (8) are at least partially formed as waveguide slot antennas (8a), each having a plurality of outlet slots (9) for the coupling of the microwaves in the interior (7).
