Construção de protótipo de mosturação automatizado a partir da plataforma arduino

Abstract

Standing out as the third largest producer of craft beer in the world, Brazil has been growing in the industry and in the beer market. This is because, consumer awareness for obtaining a better quality product has opened new microbreweries. However, together with the opening of these new ventures, it also suggested the need for improvements in the beer production process. In this perspective, the present work had as objective the construction of a mashing prototype, automated from Arduino. The development of the prototype took place in three phases, the physical construction, the development of the Arduino programming for the mashing process and the calibration of the temperature sensor. The equipment was made in stainless steel 304, with a volumetric capacity of 19.9 liters, divided into a cylinder and a basket with a mesh of 2.0 mm opening. The C ++ language was used to program an Arduino Mega 2560 and the temperature sensor DS18B20 was calibrated from a linear regression of the temperature control data in the heating process. As a result, two temperature calibration curves were obtained, using data obtained from a triplicate with 6.0 liters of water. The prototype performed an efficient temperature control in the mashing process and the construction was economically viable, when compared with the products of the same category available on the market. Thus, due to the reliability in operation and low cost, it is concluded that the objective of the work was successfully achieved, serving as an incentive and assistance to future craft beer producers.
