APPLIED ASPECTS OF USING THE SIMPLIFIED MODEL OF FACTOR INFLUENCE ON THE HOMOGENITY OF COFFEE GRAIN GRINDING

The article examines the results of experimental determination using the designed information and measurement system based on the Arduino Nano 3.0 platform of coffee grinding time values, motor shaft rotation speed, and motor stator temperature. A Mahlkönig EK 43 coffee grinder was used to grind coffee beans. The structural and functional diagram and electrical connection diagram of the elements of the measuring system are presented. A simplified model of factor influence on the homogeneity of coffee grain grinding is proposed. On the basis of the conducted dispersion analysis of the simplified model of factor influence, the values of the amount of information on each of the parameters affecting the homogeneity of the grinding, taking into account theirmutual influence, were obtained. It was established that the time of grinding gives the greatest amount of information and is the main factor that significantly affects the homogeneity of grinding.
