Projeto e prototipagem de enchedor de contrapressão para envase automático de cerveja em growlers

Abstract

This following work presents the design and prototype of an automatic counterpressure filler for craft beers in growlers. Based on the waste of craft beer at bars and brewpubs when not applying the adequate method for filling growlers, this equipment was intended to avoid the waste, maintain the quality of the product and optimize the filling process for a modern and more efficient method. The fundamental mechanism of the equipment is based on controlling the difference between the beer keg pressure and the growler. For this purpose, the internal pressure of the growler is increased almost until the pressure of the keg, and, for that, the correct manipulation of the valves generates a small pressure difference so the beer flows from the keg to the growler. Therefore, the design and construction of the automatic counterpressure filler prototype were developed and the equipment presented the expected performance, fulfilling 3 of the 4 design requirements.
