Mayak V. Scientific substantiation of processes and improvement of the equipment for the production of concentrated products from raw fruit and vegetables

Object – processes and their working parameters during the manufacture of paste-like concentrates of beverages and candied fruit from fruit and vegetable raw materials; purpose – scientific substantiation of processes and improvement of the equipment of manufacturing concentrated products from fruit and vegetable raw materials; methods of research – physic-mathematical modeling of processes, statistical analysis of the results of experimental investigations; theoretical and practical results – models of blending and flow of high-viscosity liquid are created, mechanism of heat-transfer during vacuum boiling and regularities of vacuum drying kinetics are determined, vacuum-evaporative apparatus with auger-type rake mixer is developed, rational construction materials of equipment are determined, recommendations on costs reduction during auger-type supercharger manufacture are worked out, normative documentation on new products and project documentation on the suggested equipment are developed; novelty – theory of the processes of fruit and vegetable raw materials treatment based on theoretical models of hydro-mechanical processes (flow on pipes and channels of auger-type superchargers and forming machines, high-viscosity liquids blending), heat and mass exchanging processes (vacuum boiling under condition of mixing, vacuum drying) is improved; inculcated in the enterprises of fruit and vegetable industry and into educational process; branch of industry – food industry, restaurant business.
