OLIVEROS-TASCON, C.E; SANZ-URIBE, J.R.; MONTOYA-RESTREPO, E.C  y  RAMIREZ-GOMEZ, C.A. Equipment for the Ecological Washing of Degraded Mucilage by Natural Fermentation. rev.ing. [online]. 2011, n.33, pp.61-67. ISSN 0121-4993.

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.
