The purpose of the work is a theoretical and experimental substantiation of increasing the energy efficiency of heat and mass transfer processes during drying, with further development of energy efficient heat technologies and technological line of processing of combined functional materials. The purpose of work is reached by to the carried out complex researches which are scientific novelty, heat and mass transfer processes at drying of the combined functional materials.
Energy efficient preparation of combined functional materials for drying has been developed and improved. Energy-efficient drying regimes have been developed: antioxidant raw materials, which intensify the dehydration process by 50% with a maximum conservation of 95% betanine, and intensify the process of dehydration of phytoestrogenic raw materials by 21% without critical changes in the acid value. The basic provisions of physical and mathematical numerical model of heat and mass transfer processes during drying of functional raw materials are formulated. For the first time thermogravimetric and calorimetric studies proved that the thermal stability of the created compositions is higher than the thermal stability of the components. As a result of creation of the combined product during drying the integral thermal effect in the course of evaporation - reaction of fats with fat-soluble carotenoids which influences specific heat of evaporation of water from material is registered.
The results of the work are of great practical importance: as a result, resource-saving heat technologies and technological lines were developed to obtain combined functional materials. The developed heat-technologies have been implemented at Food of the Future LLC and SEA «Everyday food». The expected total annual economic effect from the introduction of one technological line with a raw material productivity of 230-250 kg/h to obtain functional materials (antioxidant and phytoestrogenic powders) is 1075831 UAH with a payback period of 1.07 years. The introduction of the developed heat technologies in each region of Ukraine will give an actual economic effect of about 20 million UAH.
