Sidorenko V. Features of aeration and heat and mass transfer in the culture medium by method of discrete - pulse input of energy

The object of study is a process of cultural media aeration in process of yeast production. The aim of the study is study on base of theoretical and experimental researches consistent patterns of process of oxygen's absorption in the culture medium by use the DPIE-method in the process of aerobic microorganisms cultivation. Researching methods are experimental studies, which were conducted with the use of physical and chemical methods, methods of analytical chemistry and statistical data processing, analytical, computational methods. Scientific novelty is the analysis of the nature of the run of thermal processes and development of methods for determining the amount of the selected biological heat during the process of yeast production in the mass exchange apparatus with DPIE , justifying the possibility of using the RPA as aeration and mixing device in the processing of culture media without affecting cells, creating analytical methods of calculating of the process of yeast production in a mass transfer installation with recirculation using the RPA, an equation for calculating the volumetric mass-transfer coefficient is obtained, limit parameters in processing of culture media in the RPA are specified. The practical significance is in the development and implementation of pilot equipment and waste method of research, that made possible the kinematics, mass transfer and technological characteristics of the processing of the culture media determine , the development and implementation of technologies and equipment with DPIE for fodder yeast production for farms. Scope of use is agriculture and food industry.
