Automação de processo de brassagem para a fabricação de cerveja artesanal

Abstract

The consumption of craft beer is getting more and more common and popular as well as its manufacturing process. With this in mind, this project was conceived and idealized in order to create a product to facilitate the process of mashing - a key procedure for brewing artisanal beer -, thus allowing greater speed, cleanliness and effectiveness. The mashing consists of three subprocesses: Mosturation, Washing and boiling. In this way, this final paper has the objective of designing a prototype - Pan, base, hoses, sparge arm, water pump - with a hardware and firmware to achieve this product. The hardware will have a user-friendly interface allowing it to execute the process (mosturation, washing, boiling) intuitively with a quick learning curve. The multi-threaded Firmware performs each part of the process together, homogeneously and customizable by the user. It will also perform a closed-loop control of the system temperature, since certain temperature ramps configured by the customer through the interface must be respected at the sampling stage. The firmware will also perform an open loop flow control of the water pump that will circulate the temperature of the wort - a sugary mixture intended for fermentation.The firmware that performs the system automation, acquisition and temperature control of the wort was developed in C language adapted for Arduino.
