Abstract:Magistrsko delo obsega študij ter rekonstrukcijo naprave za lebdeči sloj z namenom ločevanja mlevine hitrih antigenskih testov. Z namenom karakterizacije mlevine so bile izvedene sledeče tehnike: sejalna analiza, rentgenska fluorescenčna spektrometrija, vrstična elektronska mikroskopija, energijsko disperzijska spektroskopija rentgenskih žarkov ter presevna elektronska mikroskopija. Zaključno delo zajema eksperimentalno testiranje poenostavljenega procesa separacije z zeolitnimi kroglicami in papirnatimi lističi, podkrepljeno z numeričnim modelom. Tokovne razmere obravnavanega problema so bile simulirane s pomočjo računalniške dinamike tekočin (RDT), obnašanje ter interakcije delcev pa z metodo diskretnih elementov (DEM). Ugotovljeno je bilo, da je proces ločevanja zeolitnih kroglic in papirnatih lističev učinkovit. Rezultati simulacije so pokazali ustrezno obnašanje delcev tekom procesa. Odstopanja rezultatov so razložena, predstavljene pa so tudi pomanjkljivosti ter možne izboljšave. Za opredelitev ustreznosti procesa ob uporabi dejanske mlevine hitrih antigenskih testov bi bilo potrebno nadaljnje raziskovalno delo.

Title:Reconstruction of a fluid bed device for separating granular material from the grinding process of rapid antigen test
Abstract:The Master's thesis includes the study and reconstruction of a fluid bed device with the purpose of separating the granular material from the grinding process of rapid antigen tests. With the purpose of characterization of grinded particles the following techniques were performed: sieve analysis, X-ray fluorescence spectroscopy, scanning electron microscopy, energy dispersive X-ray spectroscopy and transmission electron microscopy. Thesis includes experimental testing of a simplified separation process with zeolite beads and paper slips, supported by a numerical model. The flow conditions of the considered problem were simulated using Computational Fluid Dynamics (CFD), discrete element method (DEM) was used to simulate the behavior and interactions of particles. The separation process of zeolite beads and paper slips was found to be efficient. The simulation results showed the appropriate behavior of the particles during the process. We explained the results deviations, we also presented the shortcomings and possible improvements. To define the adequacy of the process, while using actual ground material of rapid antigen tests, further research is required.
