“…Exceptions are dill, fennel and chamomile. Baby food products for young children should not contain: flavorings, dyes, stabilizers, preservatives, sugar substitutes, food additives, except for those permitted for the production of baby food [4][5][6]. There are also a number of federal laws that must be taken into account when manufacturing products for children.…”

“…Due to this, the material is divided into many streams, which collide with each other in the annular space between the body and the cone (4) and mix intensively. Under the action of their own weight, the particles fall to the bottom of the mixer, from where they are removed by the blade (6).…”

“…Then the material, under the action of gravity, enters the rotor bowl (5), where, under the action of inertial forces, it begins to rise up along the inner surface. Due to the shape of the rotor, part of the flow returns to the plate (6), and the other part, reaching the smaller edge of the bowl, is dropped onto the surface of the body. The rise of particles along the larger edge of the rotor is ensured by the fact that the profile angle is less than the ascent angle of the particle trajectory along the generatrix of the rotor bowl.…”

The study was carried out on two mixers of different designs: basic and developed. To evaluate and analyze the finished mixture, the method of high performance liquid chromatography was used. Taurine was used as a key component. The paper describes how the rational parameters of the mixer were selected, according to which recipes the mixture was prepared, and also how the final assessment of the effectiveness of the mixing equipment was carried out. The mixtures were prepared on the equipment according to three recipes. According to the first recipe, 81 experiments were carried out, with various parameters of the mixer operation, which helped to determine their rational value. For two different mixers, they turned out to be identical, so further mixing took place with the same parameters. Based on the data obtained, graphs of dependences were built, which clearly demonstrated the difference in the obtained values of the coefficient of heterogeneity. And they made it possible to judge the influence of each individual parameter. The developed mixer design showed a lower coefficient of heterogeneity in comparison with the base one. It did not exceed 10%, unlike the latter.

The mixing process is used in various areas of production to produce different types of bulk mixtures. These include agricultural mixtures, semi-finished products, bone cements and others. This process is the movement of particles of bulk material components in the space of the working capacity. Mixers of various types are used to set the components of the mixture in motion. One of the most common types of mixers are drum mixers. The main challenge that must be addressed when developing a mixer design is to reduce the segregation that occurs when mixing two or more components of a mixture. Segregation is associated with different particle sizes and densities of the various components. The object of the study is the designs of drum mixers developed in the last decade. All considered designs are divided into three groups, differing in the method of eliminating segregation. The subject of the study is the design features of these mixers. The results of the work were the determination of the most suitable method for eliminating segregation - the use of additional mixing elements in the center of segregation of the mixture, and based on this method, the development of two new designs of drum mixers. The first mixer with sectional radial separators allows you to repeatedly separate the mixture and move the particles of its components relative to each other. This allows you to reduce the degree of segregation of the mixture. The second mixer developed not only extends the residence time of the mixture particles in the drum, but also allows for the creation of crossing and recirculating flows of material. This also helps reduce or prevent segregation.
