Introduction to Coffee processing

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, the sun-cured beans look irregular and unflattering in appearance.

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 happy coffee growers who use sacks will first pick coffee cherries from trees and then pour them into a pool filled with water. Due to the different density caused by the maturity of coffee cherries, overripe and immature coffee cherries and some branches and leaves will float on the surface, while coffee cherries ripe enough will sink to the bottom of the water. Naturally, in this way, I screened out some of the coffee cherries that passed the first hurdle. There are always friends who have just come into contact with coffee to ask, "what kind of water washing and sun honey treatment on the coffee bean bag has several meanings?"

Water washing is not coffee like people bathing with water ah, sunbathing is not people sunbathing, honey treatment is not a fragrant bath ah! Haha, the picture is too beautiful to think about it.

To get back to the point, let me briefly explain the process of washing treatment in this half bucket of water today.
