The technology of producing dry special-purpose beverages using a high-capacity blender

The technology of dry special-purpose drinks enriched with vitamins, beta-carotene and pectin has been developed. The task is to obtain multicomponent dry mixtures with high percentage ratios. The raw components differ in size, physical and mechanical properties, which characterize a mixing process as stochastic. A centrifugal mixer with cone working rotors is applied to solve the problem of thorough mixing. The peculiar feature of this device is realization of mixing of loose components in thin layers when crossing flows, which have different directions. The special feature of the device design is also mixing in discharged and intersectional layers using direct and reverse recycling under the action of centrifugal and inertial forces. The process intensity is guaranteed by distribution of dry material flows, under the action of structural blades of the instrument, reduction of dead zones due to the presence of new solutions in the device design, namely a special cone based on the rotor and structural blades. The quality of mixing is evaluated with the help of a coefficient of heterogeneity. The homogeneity of distribution is determined in terms of quantity using a variation factor. It is shown that the use of the developed mixer in the production of dry vitamin beverages makes it possible to obtain a powdered concentrate of high quality, solve the problem of lump formation and caking of loose disperse components of raw materials and their uniform distribution throughout the mass of a product. The technology has been tested at the enterprises of Valetek Prodimpex Company with the establishment of regulated quality indicators of the developed products. The nutritional value of a special-purpose product designed for optimization of healthy meals of workers in metallurgical enterprises is determined.
