Abstract

Die Erfindung betrifft ein Verfahren zum Betrieb einer Trocknungsvorrichtung (1) zur schonenden Trocknung eines insbesondere empfindlichen Trocknungsgutes, wobei die Trocknungsvorrichtung (1) wenigstens eine Druckänderungseinrichtung (2) und wenigstens ein Transportmittel (4) aufweist, mittels dessen das Trocknungsgut in mindestens eine Heizzone (5) eines Prozessraums (3) der Trocknungsvorrichtung (1) gefördert wird, in welcher wenigstens eine Temperiereinrichtung (6) den Feuchtegehalt des Trocknungsguts ändert. Um für unterschiedlich, empfindliche Trocknungsgüter produktschonende, optimierte, quasi-kontinuierliche Vakuumtrocknung erreichen zu können, wird vorgeschlagen, bestimmte Prozessparameter in jeder Phase der Trocknung kontinuierlich automatisch anzupassen. Die Erfindung betrifft außerdem eine Vorrichtung zur Durchführung des Verfahrens.

The invention relates to a method for operating a drying device (1) for gentle drying of a particularly sensitive material to be dried, wherein the drying device (1) has at least one pressure change device (2) and at least one transport means (4) by means of which the material to be dried is conveyed into at least one heating zone ( 5) of a process space (3) of the drying device (1) is conveyed, in which at least one tempering device (6) changes the moisture content of the drying material. In order to be able to achieve product-friendly, optimized, quasi-continuous vacuum drying for different, sensitive dry goods, it is proposed to continuously adjust certain process parameters automatically in each phase of the drying process. The invention also relates to a device for carrying out the method.
