There are two different methods of raw bean treatment: sun drying and water washing.

The harvested coffee beans must enter the treatment program immediately, otherwise they will begin to ferment and make the coffee beans smell bad. The main treatment methods are "sun method" and "water washing method", these two methods will cause different flavor. Sun-dried beans have a complete natural mellow flavor, gentle aroma and more gum; washing rules have a good mellow taste, high aroma and lively sour taste.

Solarization method

If coffee farmers adopt the sun treatment method to evaluate the weather permitting, they will spread the screened coffee fruits directly on the main square, let the sun exposure for 2 to 3 weeks, dry the coffee fruits, and then remove the shell of the dried coffee fruits to get coffee beans. This kind of sun-dried beans will adhere to the dried pulp layer and pectin layer, so the flavor of the coffee beans will be richer and the taste will tend to be sweet.

Complete washing method (Washed)

The peel, pulp and mucous membrane are removed by washing and fermentation. farms that use the washing method must build washing ponds and be able to introduce an endless supply of live water. During the treatment, the fermented beans are put into the pool and passed back and forth, using the friction of the beans and the power of running water to wash the coffee beans until smooth and clean. After washing, at this time, the coffee beans are still wrapped in the pericarp with a moisture content of 50%. It must be dried so that the moisture content is reduced to 12%, otherwise it will continue to ferment, mildew and rot. The better treatment is to use sunlight to dry. Although the procedure is complicated and takes 1 ~ 3 weeks, it has a very good flavor and is very popular.

Steps: screening floating beans, removing peel and pulp (retaining pectin viscous layer), fermentation, washing, drying, shelling and grading screening.

The water content of raw bean by washing method is about 12%.

The cost of washing is high. 200 grams of raw beans are obtained by washing, which requires washing 1 kilogram of coffee fruit and consuming 10 liters of water, so the treatment is expensive.
