Mash Filter Automation in the Beer Brewing Process

Zadatak diplomskog rada bio je automatizirati filtar komine, dio varionice piva. Na početku je opisana povijest piva, a zatim je uslijedio opis filtra komine. Koristeći standardni softver tvrtke Montelektro d.o.o. izrađeni su CM lista, SCADA sučelje i PLC program za ostvarenje funkcionalnosti filtra komine. PLC program je napisan u softveru Siemens Step 7. Navedene su i objašnjene sve faze kroz koje filtar prolazi tijekom programa filtracije komine. Radi testiranja funkcionalnosti programiran je i približni simulacijski model koji je pokazao ispravnost izrađenog PLC programa.The goal of this masters thesis was to document the process of mash filter automation. Mash filter is a part of brewing equipment in breweries. At the beginning of the thesis a brief history of beer was revised and after that mash filter was described. Using standard software, courtesy of Montelektro d.o.o. CM list and SCADA interface were made. PLC program for the operations of mash filter was written in Siemens Step 7 software. All operations that the filter can perform were listed and described. Also, approximate simulation model was programmed to test the functionality of the written PLC program
