Panela com controle de temperatura para etapa de brassagem da fabricação de cerveja artesanal

Abstract

Making beer at home has been growing on the market and becoming a hobby each day more common. One of the steps of the process to make it, called brew, requires that the beer wort (a mix of water and malt) follows a specific configuration of time and temperature in order to fulfill the final product specifications. The conventional process using a stove, however, presents some disadvantages, such as the need of a continuous supervision of the brewer during the whole recipe preparation, controlling the temperatures through the flames. The purpose of this work is to present a simple alternative to brew at home. The prototype of an electrical pan with temperature control was built so that through a graphical interface, the user sets up the process data, that will be performed without the need of continuous supervising. The control of the temperature is programmed in a microcontroller that uses a temperature sensor PT100 and controls the power provided to a resistive charge that heats the wort. The idea of a mechanical project, study and assembly of hardware, implementation and integration of software and data gathering are topics presented in this documentation.
