Equipo para el lavado ecológico del café con mucílago degradado con fermentación natural

an up-flow coffee-bean washer with radial fluids discharge was evaluated following a 2 by 3 factorial design; two washed coffee bean flow rates (1.250 and 1.750 kg.h-1) and three water flow rates (3, 4 and 5 l.min-1), with 5 experimental units per treatment. the best performance of the equipment was obtained with a washed coffee bean flow of 1.750 kg.h-1 and a water flow rate of 5 l.min-1, reaching mucilage removal of 95,11 %, specific water consumption of 0,32 l.kg cps-1, mechanical damage of 0,51 % and specific power requirement of 1,01 w.h. kg-1 of washed coffee.
