Automation of mash filter in brewing process using ProLeit Brewmaxx process control system

U radu je izložena kratka povijest piva te navedeni i objašnjeni tipovi i vrste piva. Objašnjen je tehnološki proces proizvodnje piva s naglaskom na procese proizvodnje koji se odvijaju u varionici pivovare. Opisana je struktura i način rada programskog paketa brewmaxx proizvođača ProLeiT. Nacrtano je SCADA sučelje za kontrolu i upravljanje filtrom komine i izbacivačem potrošenih žitarica te je napravljen upravljački program za PLC kojim je automatiziran rad filtra komine koristeći SIMATIC STEP 7. Objašnjen je svaki korak kroz koji prolazi filtar komine u proceduri proizvodnje. Navedene su komponente sustava te je objašnjeno kreiranje procedure, recepata i koraka. Valjanost sustava je testirana koristeći „engineering“ verziju SCADA sučelja.This paper presents a short history of beer and explains the types of beers. The whole technological process of brewing beer is explained with emphasis on the processes that happen inside a brewery’s brewhouse. The structure of ProLeiT’s brewmaxx process control system is shown on the example of mash filter automation. SCADA interface for mash filter and spent grains hopper was created to enable testing and controlling of the production process. PLC code automating the production process of the mash filter is written using SIMATIC STEP 7. Every procedural operation in the production sequence of mash filter is explained. The system was tested using an engineering SCADA station
