摘要：
A method for wet-processing coffee with coffee juice extraction prior to drying, wherein the mixture of ripe and unripe coffee cherries is fed by gravity into a depulper which bursts and expels the ripe coffee cherries, while unripe coffee cherries are eliminated from the base thereof without being burst. The burst coffee cherries (pulp with parchment skin or separated from same) are pumped by a must pump or bucket elevators or Archimedes screw lift. The coffee cherries (pulp with parchment skin or separated from same) are added at room temperature to reactors in the shape of cylindrical or conical tanks having a stirrer, and calcium hydroxide (hydrated cal) is added to said reactor until a pH of 6.5-7.5 is reached and/or any other bases or calcium or magnesium salts and/or pectinase are added in a ratio of 100 to 300 grams per 100 kg of coffee cherries, and also 50 ppm potassium or sodium metabisulfite with 15 to 60 minutes stirring at this temperature. Following this pretreatment, the burst coffee (pulp with parchment skin or separated from same) may follow one of two paths: In path 1, the coffee is led to a vertical presser or centrifuge or depulper, wherein coffee juice is separated containing 11-20% soluble solids in a volume ranging from 20% to 40% of the original weight the pressed or centrifuged or depulped product is led to drying terraces where it is dried to 10-11% homogenous final moisture. Following path 2, the coffee is led to a machine that separates the coffee parchment skin from the pulp, said pulp then being pressed or centrifuged or depulped, resulting in coffee juice. The juice is led from the presser to a continuous decanter which separates a clear juice from a sludge, or to a centrifuge with the same objective, that is, to separate a clear juice from a sludge. The clear juice is concentrated in a vacuum or atmospheric evaporator to a final concentration of 72° Brix to 74° Brix. The sludge is fermented resulting in a wine, which is distilled for
