Abstract

Eine Trocknungsanlage (10) für Schüttgut, insbesondere landwirtschaftliche Körnerfrüchte, umfasst mehrere Trocknungszonen (T11 - T1), die aufeinander folgend von zu trocknendem Schüttgut (20) durchlaufen werden. Ferner umfasst die Trocknungsanlage eine Luftführung (14, 16) zum Durchleiten von Luft (24) durch die Trocknungszonen. An der Luftführung ist eine erste Stelleinrichtung (44) vorgesehen, die in eine erste Stellposition "Volllasttrocknung" und eine zweite Stellposition "Schwitztrocknung" gestellt werden kann. In der ersten Stellposition "Volllasttrocknung" werden alle Trocknungszonen von Luft durchströmt und in der zweiten Stellposition "Schwitztrocknung" wird zumindest eine Trocknungszone als Schwitzzone nicht von Luft durchströmt.

A drying plant (10) for bulk material, in particular agricultural grain crops, comprises a plurality of drying zones (T11-T1), which are successively passed through bulk material (20) to be dried. Furthermore, the drying plant comprises an air guide (14, 16) for passing air (24) through the drying zones. At the air guide, a first adjusting device (44) is provided which can be placed in a first setting position "full load drying" and a second setting position "sweat drying". In the first setting position "full load drying", all drying zones are flowed through by air and in the second setting position "sweat drying", at least one drying zone as a zone of sweating is not traversed by air.
