Introduction to Qianjie-Coffee treatment

1. Drying method

Drying is a traditional processing method of coffee beans, the fruits need to be dried in the natural sun after harvest, and some mechanical drying is carried out at the same time. The process is: harvest → sun field (sunlight exposure) → sheller (remove pulp, etc.) → grading (electronic bean selector or hand selection, screen, etc.) → export.

The color of raw beans treated by drying is yellow, and the water content of coffee beans is generally about 11%, 12%. The advantage is that sun beans have better sweetness and mellow thickness, and less sour taste, which many coffee fans like very much. The disadvantage is that due to the use of artificial and natural treatment methods in the process, the sun-cured beans do not look good in appearance, do not look good, the quality is unstable, and there will be greater ups and downs.

two。 Washing method

Water washing is the most popular treatment method at present, and most boutique coffee beans will choose water washing method. Washing coffee refining process: harvesting → storage tank (removal of impurities and impurities) → 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.) → exit.

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 less miscellaneous flavor, clear taste and bright sour taste; the biggest disadvantage is that coffee beans are easy to catch sour taste in the process of fermentation.

3. Honey treatment

The honey treatment of coffee beans is to remove the peel and pulp, there will be a layer of sticky gel wrapped in the coffee endocarp, its sugar content is very high, usually called "honey". With this layer of honey, the wet coffee beans are put on the rack to dry, turn constantly to avoid pollution and mildew, and speed up the drying. this process is the honey treatment of coffee. Honey-treated coffee has low acidity because it does not undergo fermentation, showing the sweet original flavor of ripe coffee fruit and berry aroma, with the tone of red wine.

Knowledge: although coffee beans are called beans, they are actually the seeds of the fruits of Rubiaceae (coffee trees).
