Abstract

Today, food products for functional purposes, especially health-improving and preventive ones, with a high content of vitamins, microelements, macroelements, essential amino acids, and biologically active substances (BAS), are becoming more popular. Such products allow a person to maintain his or her health, as well as fully meet the physiological needs for energy and nutrients, which the body uses to build cells, organs and tissues. Therefore, it is the food industry that is currently an important component of healthcare and occupies a special place in the field of intellectual and industrial human activities. Extraction is one of the most common methods used in the process of obtaining biologically active substances from plant or animal raw materials. The efficiency of the extraction can be increased by using intensifying methods used in the extraction process, such as ultrasound. The paper considers the design and features of the mathematical description of ultrasonic systems for the intensification of the extraction process, the principle of operation of which is based on the use of piezoelectric ultrasonic radiators. A computer model has been built using the COMSOL Multiphysics software package of the ultrasonic system to intensify the extraction process, taking into account the full set of geometric, physical, mechanical and electrical parameters. As a result, the frequency at which the maximum amplitudes of oscillations of the ultrasonic system are provided for the intensification of the extraction process, which leads to the implementation of the most effective resonant mode of operation of the system, is determined. The locations of the maximum acoustic pressure on the object of extraction in the ultrasonic system to intensify the extraction process in the manufacture of concentrated drinks for functional purposes are determined. Further research by the authors can be directed to the development of a mobile ultrasonic system for intensifying the extraction process in the manufacture of concentrated drinks for functional purposes, as well as for determining the most efficient geometry of the ultrasonic system tank using the COMSOL Multiphysics application software package
