Washing coffee refining process: harvesting → storage tank (removal of impurities and immature beans) → pulp removal machine (removal of pulp and impurities) → fermentation tank (removal of mucous membrane on 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, (screen, etc.) the appearance of coffee beans washed and processed at → export is relatively neat. And there are few impurities and defective beans, and the water content of coffee beans is generally about 16%.

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

This method of processing coffee beans by honey treatment has recently been sought after by coffee lovers. It has a sweet taste and is rich in Crema. It is suitable for extracting Espresso from the base of Italian coffee. The advantage is that it can restore the flavor of coffee beans, the coffee is more sweet, and the taste of red wine is outstanding. The disadvantage is that coffee beans are very vulnerable to pollution and mildew during the drying process after the exocarp of coffee berries are removed.
