The aim was to carry out preliminary studies of drying of natural coffee by implementing a Cyclic Pressure Changes (CPCD) dryer, comparing it with solar drying and with a mechanical drying system by forced convection of low-temperature air. The drying times and rates of the systems used were compared, as well as the respective valuation of the cup quality. Drying times were 767 h for solar drying system, without reaching the desired moisture content; 153.5 h for mechanical drying system and 449 h for the CPCD system. However, the global cup tests showed a better quality of the grain obtained with the CPCD system (87 points), than the one obtained with the mechanical drying at 35°C (84 points). 2020 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49666177006 https://www.redalyc.org/journal/496/49666177006/ https://www.redalyc.org/journal/496/49666177006/html/ https://www.redalyc.org/journal/496/49666177006/49666177006.epub https://www.redalyc.org/journal/496/49666177006/movil 10.15446/dyna.v87n214.83414 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.214 Vol.87 |
