Slobodianiuk K. Intensification of the process of drying phytoestrogenic raw materials based on soy

The dissertation is aimed at solving an important scientific and technical problem - increasing the energy efficiency of the process of obtaining phytoestrogenic powder on the basis of soybean, while maintaining the high quality of the final product and nutrients. Modern research of drying and methods of processing phytoestrogenic raw materials is considered. It is established that the overwhelming amount of data relates to soybean seed drying, the separation of the shell from the bean, and energy-intensive temperature regimes for the drying of phytoestrogenic raw materials. Preliminary hydro-thermal preparation of phytoestrogenic raw materials for drying was improved and new carotene-containing ingredients in phytoestrogenic mixtures were used, which made it possible to reduce energy consumption for preparation of raw materials for drying by 20-25%. Based on the studies of the kinetics of phytoestrogenic raw material drying, a phytoestrogenic herbal mixture of soybean and spinach has been developed, which intensifies the spinach drying process by 10% and soybean by 41%, and the stepwise mode of drying phytoestrogenic raw materials based on soybean and spinostinate 21%. The change of qualitative characteristics of phytoestrogenic raw materials on the basis of soybean and its mixtures with vegetables during drying and the obtained dry powder from it was investigated. The water holding capacity of soybean spinach and soybean batat mixtures, which are hydrophilic substances with high protein content, has been determined. It has been confirmed that the dispersion of the dry protein-carotene-containing powder does not affect the value of the water-holding capacity. A critical parameter of the temperature of the coolant is established, which influences the increase of the acid number of phytoestrogenic raw materials. It is established that soy-spinach powder recovers more than twice per standard (dry milk protein). Derivatographic studies have shown that the heat consumption for dehydration is the arithmetic mean of the values of the monocomponents. Prolonged high-temperature exposure causes instant complete destruction of sugars, proteins and other nutrients of the components. Calorimetric studies have shown that, as a result of the combination of protein-containing and carotene-containing raw materials, an integral thermal effect in the evaporation process is recorded at the stage of removal of free and bound moisture. The equation of generalized speed and duration of drying of phytoestrogenic vegetable mixture is calculated and obtained A physical and mathematical model of the drying process was developed. It is theoretically substantiated and experimentally proved that the improved preliminary hydro-thermal preparation of phytoestrogenic plant raw materials for drying and dehydration by means of the developed step regimes allows to significantly intensify the drying processes of phytoestrogenic raw materials based on soybean. Innovative heat technology of obtaining phytoestrogenic powder based on soybean with spinach has been developed.
