Opis

Mixing machines used in the food industry are intended to transmit mechanical energy from the dynamic elements of the machine to the mixed medium. On a global level, mixing machines have been operated with asynchronous motors and static voltage and frequency converters, which ensures the possibility of adjusting the working parameters according to the needs imposed by the technological process. Modern mixing machines have a voltage/frequency converter that allows changing the speed of the electric motor in a wide range of speeds. The existence of the CTF converter allows changing the rotation speed of the mixing arms. Taking into account the need to obtain a varied range of revs of the mixing devices, a particularly important case in the operation of a mixing machine is that of regulating the speed of the drive motor. It is much easier to simulate the electromechanical drive system by applying the MATLAB utility and the Simulink-Sim Power Systems extensions. The mathematical approach based on mathematical models followed by a numerical simulation leads to much reduced financial efforts compared to experimental approaches.
