Dry process of coffee beans treated in the sun

The requirements of the sun treatment on the climate are very high. After the coffee fruit is harvested and dried in the sun directly, the coffee fruit will be dried in the sun for 3 weeks according to the weather conditions, and then the pulp will be completely removed by peeling machine, and then screened and graded. Sun-cured coffee beans have multiple and thick flavors, but their quality is unstable. Therefore, some people do not like it, but others like this flavor, can only be said to have their own preferences.

These painstaking steps and processes are used to be called "processing process". Treatment is one of the sources of coffee style, different treatment factors, change into a variety of characteristics. For example, there is a shortage of sunshine and water resources in Africa, and most of Ethiopia and Yemen are sun-dried beans; and the geographical environment of Latin American countries is rich in rainfall and alpine climate of volcanic rocks. therefore, most of them use water washing treatment or honey treatment which combines the advantages of both.

● Brazilian pectin sun-dried coffee beans

When it comes to solarization, the most widely used is Brazil; the disadvantage of solarization is that it is easy to mix defective beans, and the appearance between beans and beans is poor.

Dry treatment (secado), also known as natural all-day exposure (natural).

Sun drying is one of the ways to treat coffee fruits, which is treated by coffee cherries harvested and exposed to the sun for 4 weeks, turning evenly several times a day, so that the coffee cherries are evenly heated, and the core and skin of the coffee fruit will be separated after drying, and then the pulp and peel will be removed by a sheller. And so on, the screening is completed.

There are two methods of fermentation, namely wet hair alcohol and dry hair alcohol, as the name implies, the former adds water, the latter does not add water. In the process of producing alcohol, the seeds and internal pulp will have special changes, which is one of the steps that most affect the flavor of coffee after washing, at this time, the coffee beans are still wrapped in the pericarp, the moisture content is up to 50%, and must be dried. Reduce the moisture content to 12%, otherwise they will continue to be mellow, moldy and rotten. The better treatment is to use sunlight to dry, although it will take 1-3 weeks, but the flavor is very good and very popular. In addition, machine drying is used in some places, which greatly shortens the processing time and makes the flavor inferior to that of sun-dried coffee.

Brazilian coffee fields are endless and are mostly harvested mechanically in order to meet the economic benefits. When 75% of the coffee fruit in the coffee garden turns red, mechanical harvesting is started, followed by the same pre-washing operation, which is moved into the sink to remove floating beans, sift out the sunken beans, and then use a large pulp screening machine to dig out the pulp and remove the pods covered with pectin. The next stage is separate from the washing method: the sticky pods do not need to be moved into the tank to ferment, but to the outdoor bean drying farm. Because of the dry climate in Brazil, the sticky pectin on the pods will harden in about a day or so.

Then use a large number of manpower to turn up and down, so that the pods dry evenly inside and outside, so as not to return to moisture and stink. For about two to three days, with the help of the natural forces of sunlight and dry climate, the pods can achieve a certain degree of dehydration. Then further dry with a dryer, the water content is reduced to 10.5%, and the pods are stored in a special container for about 10 days to further mature, in order to stabilize the quality, remove sheep skins (pods) before export, remove coffee beans, and pack them in stages. The adhesion of the mucous membrane is very strong and is not easy to remove. It must be placed in the slot for about 18-36 hours to make it alcohol and decompose the mucous membrane.

After the coffee fruit is actually picked, it is dried directly in the sun. According to the weather conditions, it is generally necessary to dry the coffee beans for 2 weeks to reduce the water content of the coffee beans to 10%, 12%, and then use a machine to remove the dried peel and pulp. Raw bean processing plants (beneficio) usually retain the parchment shell (parchment; pergamino) on the outside of coffee beans when they are stored and are not removed until they are exported (Costa Rican law stipulates that raw coffee beans cannot be exported with parchment shells). This kind of treatment generally requires sufficient sunshine in the place of origin.
