Avaldamisel
Avaldamisel artiklid on retsensentide poolt aktsepteeritud artiklid, mis on publitseeritud elektrooniliselt käsikirja vormis, kuid mida pole küljendatud ja mis pole veel ilmunud ajakirja korralises väljaandes. Küljendamine võib põhjustada väikeseid erinevusi võrreldes avaldamisel oleva artikliga, seetõttu võivad publikatsiooni ettevalmistamise käigus muutuda nii pealkiri kui ka sisu.

One of the most important stages of the technological process of extraction of target components from oilseeds is extraction. This stage lasts the longest, and therefore, it generally determines the speed and cost-effectiveness of the whole process. A promising direction for effective organization of the extraction process is involving microwave technologies, the use of ultra-high frequency electromagnetic field (EHF) microwave energy directly in the technological process.
The complex nature of the interaction of the factors that determine the intensity of the extraction process in the microwave field does not allow establishing (create) an exact mathematical model of extraction. We propose a method of parametric identification of the mathematical description of the extraction dynamics. This method allows determining the kinetic coefficients of the process from one experimental experiment on the existing installation. A simplified process mechanism was chosen for the study and a general description of the phenomena of heat and mass transfer in a capillary-porous body was used for the known general description. The parameters of the obtained model were identified according to experimental studies. The thus obtained model of non-stationary processes can be used to optimize the parameters and automate the technical means of extraction of oil materials.
Keywords: extraction, oil raw material, microwave field, mathematical model, identification.
