Electrodischarge extraction. Educational manual

The readers presented to the readers" Electro-discharge extraction "is intended for students studying under the programs of undergraduate and magistracy in the areas of chemical technology," biotechnology "," energy-saving processes in chemical technology, petrochemistry and biotechnology "," food products from vegetable raw materials", "food products of animal origin", "pharmaceutical technology", "medical biotechnology", "technology of phytopreparations"," agricultural engineering "," Teploenergea and heating equipment "(orientation" energy supply of enterprises"), as well as for graduate students studying in the specialties related to these areas, in particular, for specialties "05 .17.08 - processes and apparatuses of chemical technologies "and "05 .18.12 - processes and apparatus of food industries". It discusses: the physical essence of the extracting processes in general and electrical explicit extract, in particular, the technological aspects of extracting biologically active components from plant raw materials, the quality of the extracts obtained, the fundamental technological design of the processes of substances from the solid phase, the kinetic patterns of the extraction process, the mass transfer in the external and internal (solid) phases, kinetic calculation of devices, the purpose of which is to determine the dimensions of the apparatus, ensuring a given performance, the intensification of the process and the equipment for its implementation. The main attention in the book is given, in accordance with its name, the acceleration of mass exchange in the process of extracting due to the creation of the “liquid -hard” electrical discharges in the system that cause experimental studies, not only the intensification of external, but also internal mass exchange - due to the penetration of the penetration turbulent pulsations inside the body, destruction of membrane shells of cells of raw materials of plant and animal origin, and in some cases and due to the grinding of particles of the solid phase. The book can also be useful to engineers and scientists involved in the extraction of substances from the solid phase
