METHOD TO DETECT QUANTITY OF GRAINS IN GRINDING DEVICE Russian patent published in 2011 - IPC A47J31/42 

FIELD: personal use articles.

SUBSTANCE: method is described how to detect quantity of grains in a container of a rotary grinding element, the specified method includes the following stages: the first turning torque (FORP1) is fed to a rotary grinding element within the first interval (T1) of a grinding cycle (CM); the first value is produced (CTM100), which indicates period of rotation of the specified element with the first turning torque; the second turning torque (RP2) is sent to a rotary grinding element within the second interval (T2) of the specified cycle, which is less than the first turning torque; the second value is measured (CTM50), which indicates the relative period of the specified element rotation with the second turning torque, the first and second values are treated (CDTR, CNFR), to generate information (ALR), which indicates quantity of grains available in the container.

EFFECT: simplified method to detect quantity of grains in a container.
