Description

mit Heizplatten und Förderrollen ausgestattete Trockenkammer für Furniere Es sind Trockner für Hölzer,- Furniere und andere plattenförmige Körper mit dichtem Gefüge bekannt, welche mit Heizplatten und Förderrollen ausgestattet sind und welche das Trockengut an der Oberfläche der Heizplatten vorbeiführen. Solche Trockner haben den Nachteil, daß das Trockengut zunächst an der Oberfläche ausgetrocknet wird, wodurch Spannungen in dem Gefüge hervorgerufen werden.Drying chamber for veneers equipped with heating plates and conveyor rollers They are dryers for wood, veneers and other plate-shaped bodies with a dense Structures known, which are equipped with heating plates and conveyor rollers and which guide the material to be dried past the surface of the heating plates. Have such a dryer the disadvantage that the dry material is first dried out on the surface, whereby stresses are caused in the structure.

Die Neuerung besteht darin, daß ein an sich bekannter Trockner vorstehender Bauart in einem abgeschlossenen Trockenraum c angeordnet ist und daß in dem Trockenraum c Leitwände g, welche abwechselnd von der Decke und vom Boden aus bis nahezu an die Heizplatten a und b reichen, angeordnet sind. In den Trockenraum c tritt durch den Stutzen d im Gegenstrom zur Förderrichtung der Furniere ein warmer Luftstrom ein, der in schlangenförmigen Windungen die Trockenkammer c durchstreicht und bei e abzieht.The innovation is that a known dryer of the above type is arranged in a closed drying room c and that in the drying room c guide walls g, which extend alternately from the ceiling and from the floor almost to the heating plates a and b , are arranged . A warm air stream enters the drying chamber c through the nozzle d in a countercurrent to the conveying direction of the veneers, which sweeps through the drying chamber c in serpentine windings and withdraws at e.

Die zu trocknenden plattenförmigen Körper f werden durch Förderrollen dem Luftstrom entgegen durch die Trockenkammer geführt und beim Vorwärtsschreiten durch die Rollen r, 2 gegen die unteren Heizplatten a und durch die Rollen 5, 6 gegen die oberen Heizplatten b angedrückt. Der durchströmende Luftstrom nimmt die aus den plattenförmigen Körpern f verdampfte Feuchtigkeit auf und sättigt sich auf dem Wege von d nach c mit Feuchtigkeit, so daß also die austretenden plattenförmigen Körper mit trocke ner Luft, die eintretenden plattenförmigen Körper mit feuchter Luft in Berührung kommen. Das Trockengut wird also durch die Berührung der Platte a an der Unterseite getrocknet, kommt hierauf bei den Rollen 3, .4 wieder mit feuchter Luft in Berührung, wird 1n Heizplatte b auf der Oberseite getrocknet und kommt bei Rollen 7 und 8 wieder mit feuchter Luft in Berührung. Es findet also eine abwechselnde Trocknung und Wiederanfeuchtung des Trockengutes statt, wodurch Spannung und Reißen des Gefüges verhindert wird. Beim Weiterfortschreiten des Trockengutes f wird die Wiederanfeuchtung immer geringer, bis das Trockengut vollkommen trocken den Raum c verläßt.The plate-shaped body f to be dried are conveyed by conveyor rollers guided against the air flow through the drying chamber and while walking forward by the rollers r, 2 against the lower heating plates a and by the rollers 5, 6 pressed against the upper heating plates b. The airflow flowing through takes the moisture evaporated from the plate-shaped bodies f and becomes saturated the way from d to c with moisture, so that the emerging plate-shaped Bodies with dry air, the plate-shaped bodies entering with more humid air Come into contact with air. The dry material is so by touching the plate a dried on the underside, then comes again with the rollers 3, .4 with a moist In contact with air, 1n hot plate b is dried on top and comes at Rolls 7 and 8 again in contact with moist air. So there is an alternating one Drying and remoistening of the items to be dried take place, creating tension and tearing of the structure is prevented. As the dry material f continues, the Re-moistening less and less until the items to be dried are completely dry in the room c leaves.
