METHOD OF CERAMIC PRODUCTS DRYING Russian patent published in 2017 - IPC C04B33/30 F26B3/04 

FIELD: heating.

SUBSTANCE: drying is carried out in a drying chamber, equipped with an automated process control system (APCS) drying to constant control of time-varying state product raw via immersed in the product, raw local conductometric sensors and automatic control using the control system of the drying process by submitting to the drying chamber acceleration or deceleration drying drying agent component. Conductivity sensors are immersed in the superficial, intermediate and middle layers of the product raw, include the supply of a drying agent, recorded decreases with drying electrical currents between the sensor electrodes, normalized current values of the currents at their initial value, logs drying process dependence of the normalized values of the currents from the drying time , and compare the difference between the observed sensor readings with the occurrence of defects in the product and experimentally determine the allowable defect-free drying for maximum difference of sensor readings, with providing defect-free drying of the differences of the sensors make the program automatic control of the drying process. The controlled drying is carried out of raw products in the drying chamber with the control system, working on drawing up a pilot program of control of the drying process.

EFFECT: increase the speed and quality of ceramic products drying, reduced the marriage, energy and time costs, productivity gains in the production of ceramic products.
