| Popis: | The making of homogenous mixtures from various materials and their interfusion is a process that has widespread use in the food industry. The quality of the finished product often relies on the outcome of this process. Therefore, the increase of requirements for the quality of mixtures makes studying the operational characteristics of various kinds of mixing equipment a must. One approach to do so is mathematical modeling. The paper reviews the simulation of the spiral and screw dispensers operations, which provide a preliminary initial stage of high-quality mixing of components. The presence of fluctuations in the dispensers leads to stochastic changes in the output signal, complicating the simulation process. Sequential structural transformations of the signal to filter fluctuations are applied to solve this problem. The apparatus of continued fractions is used to construct a mathematical model of the output signal from the dispensers as a harmonic component with a certain amplitude and angular frequency. The research results allow the simulation of processes at the inlet of continuous mixers with high accuracy. Besides, that lets us evaluate the effectiveness of the mixing processes and the influence of technological parameters on the quality of the mixtures. |
