“…Constant factors of the dispersion process in JSHM were the temperature of the cream, the recommended parameters of which were maintained in the range of 35-40°C [51,52] and the temperature of skimmed milk 60-65°C [53,54]. The variable factors of the research were: productivity, the width of the ring-shaped gap, excess pressure of the supply of skimmed milk, fat content and the speed of the supply of the DPME [48,55].…”

The jet-slit milk homogenizer is one of the most energy-efficient among all types of homogenizers in the dairy industry. The principle of its operation is based on the creation of a maximum speed difference between the fat globules of cream and the flow of skimmed milk. Reducing the specific energy consumption and finding the optimal parameters of the homogenizer were based on the results of both theoretical and experimental studies. The optimization criteria (decreasing specific energy consumption while maintaining high homogenization quality) were chosen to achieve a dispersion of 0.8 μm with minimal energy consumption. The parameters of the width of the ring gap, the fat content and the speed of the cream have been optimized. It is possible to reduce the specific energy intensity of the process to values of 0.88–0.92 kWh/t when using cream with a fat content of 33–43%, which should be fed through an annular gap with a width of 0.6–0.8 mm. Optimum values of the cream feed speed had been found, which should be equal to 7–11 m/s. The research results are of high practical value for the further development of the energy-efficient industrial model of a jet-slit homogenizer.

The article provides an analysis of the existing analytical models of the change in the cross-sectional area of the modulator in rotary-pulsation devices. The peculiarities of the application of such functions for the pulsation devices with the vibrating rotor are determined, taking into account the predominant mechanism of dispersion of emulsions. Using classical hydraulic and mathematical dependencies, in order to fulfill the requirement of creating harmonic pulsations of the emulsion in the modulator holes for synchronization with the axial oscillations of the rotor and the equality of the conditions of pulsations of the speed of the emulsion in each channel of the stator and rotor, the equation of the change in the cross-sectional area of the modulator in the pulsation devices with the vibrating rotor is determined in the form of a continuous function. This greatly simplifies the mathematical description of the function, and the subsequent analytical model of the movement of the emulsion in devices of this type. The resulting equation is necessary in determining such characteristics as the instantaneous speed and acceleration of the emulsion and the diameter of the dispersed phase after treatment.

An important task of food engineering, namely grain processing and the pro-duction of cereals and fodder, is the improvement of hulling equipment and the creation of complex technological lines for the processing of the original crops is gaining particular relevance. The reason for this is the need to carry out several preparatory stages, and, as a result, the use of additional equipment. To solve this problem, a string hulling device had been developed, the use of which allows reducing the number of operations due to the exclusion of preliminary sorting into fractions and wet-heat treatment. These operations are required by other hulling machines included in the technological lines of buckwheat processing. The structural scheme of the string hulling device had been developed and the principle of the shell removal operation had been substantiated. Theoretical studies had been carried out by the methods of analysis and synthesis of the mechanics of destruction and systematic analysis of the process of buckwheat hulling by impact. Experimental studies had been carried out using a laboratory string hulling device. The conducted analytical studies made it possible to determine the regularity between the physical and mechanical characteristics of buckwheat and the critical linear impact speed necessary for the destruction of the shell. This allows deter-mining the frequency of rotation of the string at which the destruction of the shell will occur while preserving the integrity of the core. Experimental studies made it possible to determine the quality of buckwheat hulling by determining the coefficient of integrity of the kernel and the coefficient of hulling. It has been determined that the ranges of the rotation frequency of the strings required to ensure a high degree of the buckwheat hulling technological process efficiency are within 15.8-16.9 s−1.
