VERFAHREN UND EINRICHTUNG ZUR TROCKNUNG VON KERAMIKROHLINGEN

摘要

The purpose is to provide, in order to ensure the highly economical drying of ceramic blanks, an automation solution which can be adapted to practical conditions of operation and which will enable subjective factors to be largely eliminated and the drying to be carried out in accordance with a criterion valid for all parameters, from the initial to the final parameters, and with freely programmable automatic drying chamber conditions, with documentation of the sequence of operations. The drying operation is controlled by a computer in three phases, the criterion adopted for the control being the mass of the ceramic blanks, which is measured by dynamometric devices suitable in the form of electronic pressure cells, and with the evaluation of the readings of measuring sensors, the temperature in the drying chamber and the mass of the ceramic blanks is determined, the gradient of the moisture reduction is calculated and the rate of the drying operation determined, a drying chamber complex being detected and controlled in time sequence by a central control unit.
