<p>The present invention is developed in the farming machinery field used during the wet stage of the coffee and refers to an apparatus that allows carrying out the processes of demucilaging, cleaning and washing of the previously depulped coffee seedcases using a low water and power consumption. Said apparatus comprises a mechanical feeding system for depulped beans, as well as a system for removing the mucilage and further washing of the beams that is constituted by a vertical rotor provided with metallic fingers that generate friction between the grains to be demucilaged, and also two metallic baskets, the first one is conical shaped -where a variable pressure zone between beans is generated, making possible a efficient detachment of the mucilage-, and the second one is cylindrical shaped one -zone of greater agitation between the beans and lower pressure between them and where a minimal amount of water is used for final washing-, which are built with square rods forming a continuous spiral which enables an easy evacuation of mucilage and other impurities through the horizontal slots due to the centrifugal force produced by the spin of a rotor. Finally, the present invention refers to a method for demucilaging, cleaning and washing depulped coffee by using of the above mentioned integral machine.</p> |
