METHOD FOR AUTOMATICAL CONTROL OF PROCESS OF DIATOMACEOUS EARTH THERMAL REGENERATION Russian patent published in 2017 - IPC G05D7/00 G05D29/00 F26B3/10 B01J20/34 B01J20/14 B01D1/00 B01D41/02 C01B33/12 

FIELD: food industry.

SUBSTANCE: for automatic control of the process of diatomaceous earth thermal regeneration according to the measured parameters of costs and capacities during the process according to the program-logic algorithm incorporated in the microprocessor, operative control of technological parameters is carried out taking into account the bilateral restrictions imposed thereon. Total heat energy costs for the process of diatomaceous earth thermal regeneration are calculated, their derivative is determined in terms of the amount of the moisture separated. Depending on the sign of the derivative, the consumption of the initial product is affected in the inverse relation.

EFFECT: invention allows to improve the efficiency of the diatomaceous earth regeneration, the accuracy and reliability of controlling the technological parameters at all stages of the process, to reduce material and energy costs per weight unit of the finished product, and to improve its quality.
