PLC-based control and HMI monitoring of the temperature in the maceration and cooking process in the craft beer production

Abstract

The brewmaster, in charge of the craft beer production, for the fact itself of being craft made, has to deal with disturbances within the manufacturing process which tend to affect the product’s quality as well as modify its taste; such disturbances occur in the wort maceration and cooking stages, where temperatures must be constant during these phases. As a concrete solution alternative proposal to this problem, without modifying the way in which the craft beer is made according to that established by UNESCO, in this work a cascade PID type control is used in order to accomplish control over a gas valve to regulate a fire flame generating the temperature inside a reactor in the maceration and cooking stages, in addition to implement a HMI for process monitoring. The present work constitutes a terminal academic project as implementation, focused on industry process automation.
