Removal of floating beans by ●-drying-shelling-grading-polishing

The sun drying method is also called "natural drying method" because it uses natural sunlight to dry the fruits and raw beans of coffee. Due to the use of artificial and natural treatment methods in the process, sun-dried coffee beans look irregular and unflattering in appearance.

● 1. Select beans

Put the harvested fruit in the water tank, and the ripe fruit will sink, while the unripe and overripe fruit will float up and can be removed.

● 2. Dry

Lay the coffee cherries in the sun for 2-3 weeks and turn them several times a day until they are fully dry. At this time, the fruit becomes dark brown, and the water content after the sun should be 10% 14%.

● 3. Shelling

After drying, the peel becomes fragile and easy to fall off, and can be removed by machine. Farms run by enterprises usually have their own shelling factories, while small farms are processed by processing centers.

● 4. Selection and grading

Exquisite farms identify defective beans manually or by machine, pick them out and throw them away. Manual selection usually uses a transmission belt about 1 meter wide, with several female workers sitting on both sides visually picking out bad beans, and some good farms are even selected several times until defective beans are not seen. Machine selection rules use computers to identify defective beans, followed by a grading process that divides coffee beans into several quality grades according to established standards. Good coffee enters the selected coffee market, while bad coffee flows into the commercial coffee market.

● 5. Polishing

The exocarp and endocarp can only be removed by shelling treatment. At this time, the silver film is still wrapped in the outer layer of the seed, and the film has to be ground off by machine. Then, the coffee beans are bagged, mostly in sacks.

● summary

Advantages: simple process and low cost (especially in water-deficient producing areas). Under the premise of proper treatment, alcohol has better thickness and sweetness, and most of them have ripe fruit flavor or wine flavor.

Disadvantages: strong dependence on the weather, the degree of dryness is difficult to control. In the sun process, it is easy to mix with miscellaneous odors, at the same time, because the pulp has not been removed, it is prone to mildew and lack of stability.
