Method for drying bulk materials, in particular solids, such as granulates, powders, grains, foils, shavings or the like, preferably plastic granulate

A method for drying solids bulk material in one or more dryers and material containers that are interconnected to form an assembly, said method comprising:

• transmitting a residence time for drying the solids bulk material by way of a superordinate controller or by way of production resources, or is set in a controller of a respective one of the material containers, or of the one or more dryers by a user in a form of a local database;
• transmitting a material consumption or a shot weight per production cycle, respectively, or an individual or cumulated shot weights for several production cycles or other values indicative of material consumption to the one or more dryers and material containers, directly or indirectly via the production resources or superordinate controller;
• providing each material container on a control side of several loading batches, with time stamps, in a form of a ring buffer and for respectively oldest loading batch residence time results from a difference between a current time of respective material removal by the production resources or superordinate controller and a time stamp associated with the oldest loading batch;
• subtracting a current material consumption transmitted by the production resources or superordinate controller from a respectively oldest loading batch in the ring buffer until said oldest loading batch is completely used up, whereby a next oldest loading batch, that is a next entry in the ring buffer, is subsequently used for a subtraction calculation.

• keeping the controller or controllers of the dryers or of the material containers respective entries for loading batches, at least time stamps in the form of the ring buffer;
• subtracting a current material consumption transmitted by the production resource or the superordinate controller from the respectively oldest loading batch in the ring buffer until the loading batch is completely used up, whereby a next oldest loading batch, that is, a next entry in the ring buffer, is subsequently used for a subtraction calculation;
• resulting with a new loading batch for a specific material container from a conveying cycle of bulk material conveyor associated with a loading of the specific material container.
