Desenvolvimento de um sistema de controle e monitoração da temperatura de brassagem na fabricação de cerveja artesanal

Abstract

Beer is the most consumed alcoholic beverage in the world. Its production occurs in two forms: multinational breweries with production of large scale beers and craft breweries that search to produce special beers. The brewing process has several stages from its elaboration to its bottling. One of these processes is the mashing, its function is to enable the enzymatic action by converting the starch of the malt grains into fermentable smaller sugars. This study aims at the construction of equipment that can communicate and be able to monitor and control the brew temperature in the artisan mashing process. There are three equipments developed throughout the project, being a thermometer, a controller and a data center. The equipment uses the UDP to communicate over Wi-Fi networks. The thermometer is a client, which measures the mashing temperature and sends the data to its servers. The servers, controller and data center, receive the data and deal with different ways, the first performs a control mesh with the temperature received and second saves the data in a database and makes them available in a graphical interface. The mashing temperature can reach close to 80ºC, all components must be able to withstand this temperature and the instruments work precisely in this range. The equipment performed well in the tests and need improvement so that in the future they could become useful products for craft brewers.
