The article provides information on the production of sports nutrition in centrifugal continuous mixers. Special attention is paid to the production gainers. The paper deals with mathematical modeling of mixing bulk materials. During carrying out of theoretical analysis, based on the correlation approach, we have established the influence of leading streams in the mixer, contours of external and internal recycling to reduce the fluctuation of the input signal. In this case, the smoothing ability of the mixer reaches its maximum value. On the basis of the cybernetic approach, we have developed a mathematical model of centrifugal mixing unit for processing of bulk materials. Time-frequency analysis of the model shows the degree of smoothing fluctuations of the input signals of the mixer according to the rotor speed. We discussed issues the instrumental and methodological support experimental research. This article provides information that in research dosing and mixing processes used powders and fine-grained materials with different physical and mechanical properties. It is reported that the choice of bulk materials depends on the realization of the new equipment in an industrial setting. In the new design of a centrifugal mixer we spent a full factorial experiment of the third order, which allows to determine the quality of the mixing process depending on external factors. The research resulted in regression equations for a mixture of "Gainer - Creatine." On the new centrifugal set we identified its rational design and technological parameters of operation. The article refers that the new mixer has been successfully commercial tests and is recommended for use in the technological scheme for producing mixtures for sports nutrition.
