Introduction to the treatment of raw coffee beans-semi-washing method
It is a relatively new and rare method. This method is also suitable for processing local coffee only in specific areas of some countries where there is a long drying period in the climate. The coffee produced by this method is sticky, and the mucus is not removed with fermentation in the tank. Therefore, the coffee produced by this semi-wet treatment contains the characteristics of both wet treatment and drying treatment. The acidity, sweetness, seasoning, and flavor of such coffee are quite good; the only drawback is that the taste of such coffee is not as strong as that produced by pure drying or washing.
Bean selection: first put the coffee fruit into the big water tank, move the red fruit and semi-green and semi-red fruit into the pulp sieving machine to remove the pulp and impurities.
Remove pectin: take out the coffee beans, do not need to take the sun, let alone pour into the sink to ferment, but directly into the next pectin scraper, only a small amount of water can scrape away the sticky pectin chips mechanically.
Sun exposure: then take out the raw beans with a smooth surface and expose them outdoors until the water content is reduced to 12%.
