Biorreactor Automatizado para la Fermentación Controlada de Café

Abstract

Even though the coffee is the base product of Colombia, its processing from harvesting to the final product is a traditional and little-industrialized process, even though there are already advances and studies that prove the improvement of the product. In the case of the fermentation phase, it is evident that carrying out this process controlling the variables that intervene in it, represents an improvement in the quality of the cup and a decrease in physical defects. In the absence of an affordable tool for the coffee producer that facilitates data recording and carrying out a successful and replicable fermentation, this project is based on developing a prototype of an automated Bioreactor for coffee fermentation, which allows to visualize, control and monitor the variables involved in the process, in order to provide technological assistance to the coffee producer to carry out a controlled fermentation and improve the quality of the product. The solution developed is a robust and reliable device that allows, in addition to the continuous recording of data during the fermentation process, a real-time visualization of the sensors and actuators, which make it easier for us to control the variables of temperature, pressure, PH, brix degrees. and alcohol in the parameters and desired adjustment values.
