Qianjie-A brief introduction to the treatment of coffee in the sun and washing

All kinds of treatment methods, the purpose is the same, is to peel the beans. Due to the economic considerations of the cost, as well as the differences in climate and other natural environmental conditions, the process of collecting beans may not be the same, but the process will affect the results!

Solarization: tanning is the oldest and most convenient way to treat raw beans.

Sift out the floating beans: pour the harvested coffee fruit into a large trough, and the ripe and full fruit will sink to the bottom; the underdeveloped or overripe fruit will surface and the floating beans need to be removed.

Drying in the second day: then put the whole coffee fruit with meat belt on the bean drying farm and dry it to a moisture content of about 12%. It takes about two to four weeks, depending on the climate of the place of origin.

three。 Shelling: the dried fruit will be naturally dried and the peel, pulp and sheepskin will be removed by the shelling machine, and the raw beans will appear.

The advantages of solarization: 1. Simple, low processing cost. 2. The raw bean is naturally dried in the pulp and absorbs the essence of the fruit, so the fruit is rich, sweet and mellow in thickness.

Disadvantages of solarization: 1. In some producing areas, the sun treatment did not screen the floating beans, resulting in quality ups and downs. During the drying process, the pulp is prone to mildew due to the return of moisture, polluting raw beans 3. The shelling of the machine inevitably hurts the raw beans, resulting in appearance defects.

Washing method: washing method is a common method of raw bean treatment at present.

one。 Sift out floating beans

two。 Pulp removal: fresh fruits are sent to a pulp screening machine (pulping machine) to remove the peel and pulp. Immature fruits are screened at this stage because it is not easy to separate the pulp. After the pulp screening machine, all that is left is pectin, sheepskin and seeds.

three。 Fermented de-pectin: transfer the peeled seeds with pectin into the fermentation tank. Although the name is water [washing] method, in fact, it is not really washing off pectin, but through the fermentation process, pectin is biodegraded. The fermentation process is about 16-36 hours, during which the pectin must be stirred frequently to accelerate the separation of pectin from the seeds. Water washing fermentation produces acid substances such as citric acid, malic acid and acetic acid, which seep into raw beans, making the beans sour more sour than in the sun. After the fermentation is completed, it is really washed-- wash the beans again.

four。 Drying: after washing, it also needs to be dried by sun or machine to reduce the water content to 12%. Because the flesh has been removed by washing

So in the drying process, you don't have to worry about mildew like the sun method. Dried sheepskin raw beans are not as hard as those with pulp and peel in the sun, and can be obtained by using a hulling to remove the shell.

The advantages of washing method: 1. Raw beans are dark green in color, complete in appearance and sell well. 2. The sour taste and bright feeling are better than the sun-dried beans, and the flavor is cleaner.

Shortcomings of washing method: 1. In order to obtain 200g raw beans, it takes 1 kg of fruit to be washed and about 2-10 liters of clean water to be consumed. The cost is high.

Arabica coffee has a low caffeine content, ranging from 0.9% to 1.2%. It is rich in fat and sugar, so it smells soft, unirritating, fresh and sweet, and sometimes has a refreshing and sour taste. Loved by most coffee lovers.

Arabica coffee smells like grass when it is not roasted. After proper roasting, it shows "fruity" (medium-light roasting) and "caramel sweetness" (deep roasting).

Knowledge expansion: Arabica coffee beans are mainly grown in South America, Central America, Africa and Asia. Yunnan, Hainan and Taiwan in China also grow a small amount of Arabica coffee beans.

In short: Qianjie is a coffee research hall, happy to share the knowledge about coffee with you, we share unreservedly just to make more friends fall in love with coffee, and there will be three low-discount coffee activities every month. The reason is that Qianjie wants to make more friends drink the best coffee at the lowest price, which has been Qianjie's tenet for 6 years!
