Abstract:Diplomska naloga opisuje postopek avtomatizacije in vodenja laboratorijskega pasterizatorja, namenjenega analizi toplotne obdelave živila za namen pasterizacije. Stroj je bil za lastno uporabo razvit in izdelan v slovenskem podjetju Petek Proces d.o.o., ki se primarno ukvarja z izdelavo tunelskih pasterizatorjev in ki takšen stroj potrebuje za kreiranje pasterizacijskih temperaturnih režimov raznih napitkov in živil. Osnovna naloga laboratorijskega pasterizatorja je gretje oziroma hlajenje produkta po v naprej določenem temperaturnem režimu. Slednje je doseženo s temperaturno regulirano vodo, katera s pomočjo črpalke cirkulira iz internega bazena na pršilne šobe, se razprši po analiziranem produktu in steče nazaj v bazen. Za temperaturno regulacijo se s pomočjo regulacijskih ventilov v procesno cirkulacijo dozira hladna, sveža voda ali v zalogovniku pripravljena vroča voda. Krmiljenje se izvaja na Siemens 1500 krmilniku, s katerim se upravlja preko Siemens HMI uporabniškega vmesnika. V nalogi je najprej opisana tehnika pasterizacije in njena vloga v prehrambni industriji. Na podlagi procesne sheme in električnega načrta so opisane posamezne komponente stroja, njihova funkcija in medsebojna relacija. V drugem delu so v obliki logičnih tabel, besedila in funkcijskih ter procesnih diagramom opisane operacijske in krmilne zahteve ter njihova implementacija v programskem okolju TIA portal. V zadnjem delu so predstavljene in med seboj primerjane različne metode pridobivanja parametrov PID regulatorjev. Za namen ugotovitve, katera metoda je najprimernejša za opisano aplikacijo, so vse testirane na praktičnem primeru.

Title:Automation and control of laboratory pasteurizer
Abstract:Dissertation describes the process of automation and control of a laboratory pasteurizer intended for the analysis of heat treatment of food and drinks. The machine was developed and manufactured for personal use by the Slovenian company Petek Proces d.o.o., which primarily deals with the production of the tunnel pasteurizers and needs such a machine to create pasteurization temperature regimes for various drinks and foods. The basic task of a laboratory pasteurizer is to heat or cool products according to a predetermined temperature regime. The latter is achieved with temperature-regulated water circulation, which, with the help of a pump, circulates from the internal pool to the spraying nozzles, disperses over the analyzed product, and flows back into the same pool. For temperature regulation, cold freshwater or hot water prepared in the storage tank is dosed into the process circulation with the help of control valves. Control is carried out on a Siemens 1500 controller, which is managed via the Siemens HMI user interface. The assignment first describes the pasteurization technique and its role in the food industry. Based on the process diagram and electrical plan, the individual components of the machine, their function, and mutual relationship are described. In the second part, operating and control requirements are described in the form of logic tables, text, and functional and process diagrams, as well as their implementation in the TIA portal software environment. In the last part, various methods of obtaining the parameters of PID controllers are presented and compared with each other. To determine which method is most suitable for the described application, they are all tested on a practical example.
Keywords:Automatization, control, pasteurization, TIA portal, PLC.
