Mechanical semi-water washing of coffee beans

Not all producing areas can use the Brazilian half-sun method. If the producing area with heavy moisture is allowed to take out the pectin pods and expose them outdoors, it is not only not easy to be dehydrated and hard, but also easy to parasitize molds. Therefore, mechanical semi-washing has been developed in areas with heavy humidity, which saves both labor and water.

First of all, the red fruit and half-green and half-red fruit sunk into the sink into the pulp sieving machine to remove the full pectin, and there is no need to take it to the sun, let alone pour it into the sink to ferment, but directly into the nearby pectin scraper (Demucilager) with a small amount of water, which can mechanically scrape off the sticky pectin shavings, take out the smooth pods, and expose them outdoors until the water content is reduced to 12%.
