There is known equipment for mixing of heterogeneous food mixtures analyzed in this article. Some part of this equipment provides qualitative mixing at macro-level (mixing of large portions of processed material), for example, paddle, propeller, turbine, anchor, screw, gravitation and drum mixers. Another part of mixing machines on the contrary, allows to achieve of effective micro-level mixing (mutual movements of adjacent particles of material) – vibratory and centrifugal mixers. In some cases there is important to provide well mixing both at macro- and at micro-level, when it is accompanied by thermal, diffusion or chemical processes and from its efficiency depend energy expenses and qualitative characteristics of product. Therefore, a task of elaboration of schemes of improved apparatuses for effective macro- and micro-mixing of dry and liquid multi-component food materials is resolved in the article. Authors are proposing to create these apparatuses at the base of well known equipment – gravitation and screw mixers by way of their additional equipping with serial electromagnetic vibro-exciters of ultrasonic oscillations. As a result, a main drive of a base mixer will provide working process at macro-level and an additional drive – micro-level movements of material particles. The proposed apparatuses have a simple and reliable construction, don’t consist of original parts and at the same time, provide necessary efficiency of working process. Equations of movements of processed components particles in course of their different loading stages, with examination of physical-mechanical properties of the components are also presented in the article. These equations can be used as a base for further creation of methods of design calculation of proposed apparatuses.
