Increasing the efficiency of the process of mixing components in the industrial production of dry mixes

Industrial mixers of solid bulk or powder components have been widely used in food, cosmetic, pharmaceutical, chemical, and many other industrial branches. Industrial mixers are designed for homogeneous mixing of dry ingredients: fodder, groats, bio supplement, fertilizers, flour, spices, etc. The general principle for all types of dry mixing is to take the product that is being mixed from one area and transfer it to another area. This procedure is repeated many times, and in the process of additional edge mixing of the zones, it leads to the distribution of the components in each other. When preparing a dry mixture, it is advisable to use spiral mixers that provide high mixing quality, low energy consumption, and high productivity. The article presents a spiral mixer for the industrial production of dry mixes, in the body of which two concentrically arranged helical spirals are placed along its length. In this case, the inner spiral has the ability, in addition to the rotational movement, to perform the axial reciprocating movement. The results of theoretical studies on the determination of the throughput capacity and the influence of the parameters of the internal spiral on the performance of the dry mix mixer being developed are presented.
