Description of Flavor of Coffee washing method introduction of Grinding scale Sun Honey

Coffee treatment method 1, choose 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:

Put the selected ripe fruit in the square and expose it to the sun for 5-6 days until it is fully dry. At this time, the fruit becomes dark brown and the moisture content is 13%.

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, polish:

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, pack the coffee beans into a bag of 60KG. The weight of bags varies slightly from region to region. Most of them use sacks.

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, so many coffee fans like it very much. The disadvantage is that due to the use of artificial and natural treatment methods in the process, the beans of the sun method do not look good in appearance, do not look good, the quality is unstable, and there will be greater ups and downs. Washing method is the most popular treatment method at present. Most boutique coffee beans will choose 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.

Due to the peeling machine, there is bound to be some residual pulp still attached to the parchment of coffee beans. Coffee beans are then placed in a fermentation tank to decompose the residual pulp and parchment with natural enzymes. The fermentation process usually ends within 24 to 36 hours, depending on the temperature, the thickness of the residual pulp, and the concentration of enzymes. Next, the coffee beans will be washed with clean water until the pulp and parchment are removed. The fermentation process must be strictly monitored, otherwise, some bad sour taste or taste will be contaminated on the coffee beans. After processing, the surface of the coffee beans will become rougher and less sticky.

After fermentation and washing, the water content of coffee beans is about 57%. Due to the excessive moisture of coffee beans, the water content is usually reduced to 12.5% by machine drying or sun exposure. If you use machine drying, it usually takes 2 to 3 days to effectively reduce the water content to the ideal data. If you use the sun, you need the weather, and the relative time will be extended to 1-2 weeks.

When the water content of coffee beans is effectively reduced to 12.5%, the coffee beans will be stored for export. Finally, before the coffee is exported, the parchment and the last layer of silver will be removed by machine. Then, it goes through the steps of cleaning, screening, classification, classification, and packaging.

Washed coffee beans can make the coffee taste cleaner, free of miscellaneous flavors and have charming fruit aromas. The color of washed coffee beans will be more turquoise or grayish green. The coffee in the washing process tastes clear, bright and free of miscellaneous flavor.
