Embodiment Construction

[0028] refer to image 3 , 4, 5, 6 and 7, describe the preferred embodiment of the present invention in detail:

[0029] Coffee Bean Cleaning Machine(17)

[0030] Coffee bean cleaning devices can be manufactured to process washed coffee beans in quantities between 500 kg / h and 5000 kg / h. The components in each module for processing different amounts of coffee beans are the same, in terms of cleaning machine (17) size and number of agitators (2), drive propeller (7) and intermediate propeller (6), rotor size (1) changes, as shown in Table 1. The rest of the components in each module - such as the tank, the worm wheel that feeds the coffee beans to the cleaning agent at the required flow rate according to the model, the number of depulpers and their capacity - have different dimensions according to the capacity of each.

Abstract

The instant invention discloses a coffee washing machine wherein the coffee mucilage has previously been degraded by means of natural fermentation or by the addition of pectinolytic enzymes, wherein the degradation process minimizes the coffee's environmental impact together with the washing process. The method disclosed in the instant invention comprises: i) depulping coffee berries; ii) conveying coffee to a screening system in order to remove berries not depulped and the vast majority of the pulp; iii) conveying depulped berries to a tank, iv) storing the depulped berries in tanks allowing for mucilage degradation either through natural fermentation or by use of pectinolytic enzymes; v) conveying coffee from the fermentation tank towards the mechanical washer; vi) removing the degraded mucilage, allowing for washed coffee ready to initiate the drying phase.

Description

technical field [0001] The general field of the invention includes techniques for wet coffee bean processing without polluting water sources. More specifically, the present invention relates to a machine and a method of coffee bean washing without prior mucilage degradation by natural fermentation or by addition of pectinolytic enzymes, controlling the 100 % of water pollution, thereby completely reducing the impact of hydrolyzed sugar wastewater on the environment. Background technique [0002] During wet coffee bean processing, the two structures that cover the bean — the fruit's cuticle (or exocarp) and mucilage (mesocarp) — are removed. To remove mucilage from coffee beans, natural fermentation and washing, or mechanical equipment are used. When natural fermentation is used, the coffee beans are left in the tank for 16 to 20 hours in order to allow mucus degradation by microbes and enzymatic activity on the beans. The degraded mucilage was then passed through differen...
