Water washing is the most popular treatment method at present, and most boutique coffee beans will choose water washing method. Washing coffee refining process: harvest → storage tank (removal of impurities and immature beans) → pulp removal machine (removal of pulp and impurities) → fermentation tank (removal of mucous membrane attached to endocarp) → washing pool (selection of light and hard beans) → sun drying field (or dryer) → sheller (removal of endocarp) → grading (electronic bean selector or hand selection, sieve, etc.) → outlet.

Washing drying field

The appearance of coffee beans processed by washing is neat, and the impurities and defective beans are less, and the water content of coffee beans is generally about 16%. The advantage is that it has less miscellaneous flavor, clear taste and bright sour taste; the biggest disadvantage is that coffee beans are easy to get sour and astringent taste during fermentation, and a fermented bean will spoil 50 grams of beans.

Semi-washing, also known as "honey treatment", is a compromise between drying and washing, eliminating the need to ferment coffee fruits. Harvest → storage tank (remove impurities and unripe beans) → pulp removal machine (remove pulp and impurities) → washing pool (select light and hard beans) → sun field (or dryer) → sheller (removal of endocarp) → classification (electronic bean selector or hand selection, sieve, etc.) → outlet
