This project will give you a view from another side when it comes to control engineering and mechanical construction in brewing. This is a thesis project about principles for an automatic brewing machine. This project started off with prestudy of earlier research results in automatic brewing based on the Arduino platform. This project shows principles about mechanical construction and creating a control system by using inexpensive commercial products such as CodeSys and Raspberry Pi. The project report begins describing the mechanical construction, how it works and it shows how it looks. The mechanical construction is a tall scaffolding which is the chassis of the brewing machine. The history background about brewing is reviewed and the fundamental methods about brewing are described as well. The goal of this project is to present principals by using CodeSys and Raspberry Pi together. Notice that this is not a construction document. This document does not include production wiring diagrams or blueprints – only principles of wiring diagrams and figures of the machine, designed in a CAD software. This brewing machine includes a few different kind of control systems to automate the process. The processes are a hops container that can deliver a set of hops in a specific time, motorized whisks to distribute the heat, heat exchanger for cooling down, heating control system and a drain control system. The main focus in this project is the mechanical parts, the flow system, the control systems and a discussion about each sub system. Results shows a lot of pictures of the complete system with text that explain the pictures. What was good, what was bad and what could be done better.
