This paper presents the results of research of the contact method of volumetric temperature control of a polymer sample. The scheme of thermocouples (TC) location in a polymer sample, finite-element model and general mathematical model for calculating the influence of the quantity of thermocouples on heating samples at high-frequency processing are constructed. Comparative analysis of the obtained results was conducted.

One of the main quality problems of products made of polymer materials is the excessive moisture content in the feedstock. Earlier developments of the authors show the possibility of controlling and eliminating this factor by the method of preliminary acclimatization and drying of the material. Automation of drying of raw materials for polymer packaging at the enterprise cannot be developed and implemented without preliminary research of the drying process, development of recommendations for the organization of an automated control system. The issue of drying multicomponent and composite materials in the finished mixture remains open today. (Research purpose) The research purpose is developing an algorithm for automating scientific research of the high-frequency drying process of multicomponent polymer materials. (Materials and methods) The article presents the existing automated systems for scientific research of high-frequency processing and their methodology, based on previously stated controlled parameters. The article describes the approach and the algorithm for an automated system of scientific research of the drying process of a multicomponent polymer mixture. A new temperature parameter controlled in the volume of the heated polymer was proposed. The depth of the controlled layer was selected according to the described methodology. (Results and discussion) The system was protected from breakdown phenomena, which limits the current consumption in automatic mode in accordance with the characteristics of industrial equipment (0.9 amperes). The automatization of control system was made using the studied law of changing the power of a high-frequency generator on the rotation angle of the regulator. (Conclusions) The developed system of automated scientific research made it possible to conduct a series of experiments, the results of which, after final processing, will be presented to the scientific community in the near future.
