Melhorias ao controle e ao monitoramento remoto de variáveis em cervejarias artesanais

Abstract

The possibility of brewing craft beer using brewing kits in smaller spaces, such as conventional kitchens and apartments, has become increasingly common among people who like to produce their own drink. However, there are some steps that must be followed, one of which is fermentation, which deserves special attention when monitoring the evolution of two essential variables, temperature and density. In this sense, inadequate monitoring of these variables can cause some problems, such as negatively interfering with the flavor of the drink, wasting the product, contaminating the drink, and can also lead to explosions of glass bottles containing beer. Based on this information, the objective of this work was to obtain measurements of the variables using the iSpindel digital densimeter, so that the brewer can remotely monitor temperature and density online using a web application. This way, the brewer can monitor the fermentation progress from anywhere with Internet access. In addition, temperature control of the recipe defined by the user was carried out on the TagoIO web platform. In this way, the ESP32 microcontroller was responsible for executing the entire temperature control process throughout the fermentation, according to the parameters entered by the user. Furthermore, the system allows you to advance the fermentation stages, if necessary. Regarding the results of this work, it was possible to obtain a physical controller structure, in addition to manufacturing a real batch of beer and obtaining the density curve and temperature ramps during fermentation, in addition to some comparisons between the measurements obtained with the iSpindel digital densimeter and manual measurements of the main variables.
