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 immature and overripe fruit will float up and can be removed. 2. Drying: put the selected ripe fruit in the square for 5-6 days until it is fully dry. At this time, the fruit becomes dark brown, moisture content 13% 3, shelling: the dried 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: delicate farms will 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. At this time, the silver film is still wrapped in the outer layer of the seed, and the film must be ground 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.

Bourbon coffee is a variety of small-grain coffee second only to Tibica. At first, the main branch and the trunk grew upward at 45 degrees, and drooped with fruit load, the lateral branches were denser, the fruit was more, and the yield was higher. But the berries are smaller and ripen more slowly. The top bud of Bobang is green, which is called green top coffee.

Many chopped beans, adzuki beans and bad beans still have a lot of defective beans after drying, so we hand-picked them on the spot and finally left 9 kilograms of qualified ones-- and most of the morning has passed, of course, if it is used to make instant coffee or general commercial beans, high-yield catimor is a good choice, but we want to find Yunnan specialty coffee. Then the old variety of iron pickup has become the first choice because of its congenital excellent gene. Therefore, this trip to Yunnan also followed the trail of the old varieties. But the reality is really cruel. Before going, Brother Zou told me that there was an old variety in his relative's house, but what he saw excitedly was a wild growing coffee forest, which belonged to his aunt. Because his aunt was too old and did not have the strength to replant and renovate-- these old varieties survived, but the aunt was unable to manage it alone, so the tree was allowed to grow naturally. To pick some fruit when ripe, the so-called new variety actually refers to catimor, which is a hybrid of timor and Arabica from the Roberta family. Compared with the old variety, it lacks rich aroma and taste, and has a relatively shallow smell of grass and soil, but it has the advantages of resistance to diseases and insect pests, easy management and high yield, and its yield per mu is up to 350kg, which is more than twice that of the old variety.
