Energy-Efficient Technologies of Plant Raw Material Extraction

The aim of this work is to create the scientific foundations of microwave extractors implementing the effect of mechanodiffusion discovered by the authors, as well as visual, kinetic, and energy substantiation of the fundamentals of mechanodiffusion, and optimization of the operating parameters of this process. To achieve this aim, a concept of innovative extractors has been formulated — sequential reduction of the extractant layer on the surface of the solid phase. Comprehensive experimental studies have been conducted, and the time of rational energy use has been determined. A model is presented that makes it possible to determine the operating mode of the extractor depending on the specific power of the generators. A methodology for the calculation and optimization of microwave extractors with the objective function of minimum energy consumption is presented. An example of estimating energy overconsumption is given. A scientific and technical hypothesis for the creation of innovative extractors that would solve traditional problems is formulated. The most significant result of the work is that the foundations for the design and optimization of energy-efficient continuous microwave extractors have been created, making it possible to obtain polyextracts in a single apparatus. The significance of the work lies in the development of mechanodiffusion theoretical foundations and the proposal of engineering methods for optimization of microwave extractors. The result is an electrodynamic extractor that could be of commercial interest in the cognac industry.
