Introduction to the process of growing, harvesting, processing and processing of coffee beans

The picking process of coffee beans

The treatment is to spread the coffee cherries widely on the exposure field for two weeks and sweep them with a rake several times a day so that the coffee beans can be dried more evenly. When dried, the coffee beans are separated from the skin, and the dried pulp and peel are removed by a sheller, then screened and divided into different grades. Both washing and drying can produce the best quality coffee. Generally speaking, water-washed coffee has distinct acidity and consistent flavor, while dry coffee has lower acidity and more varied flavor. Colombia, Kenya, Costa Rica, Guatemala, Mexico, and Hawaii all use water washing methods. Most of the coffee produced in countries including Brazil, Ethiopia and Indonesia is dried, but there are also some wet-processed coffee beans, also known as "washed beans". Wash the fresh coffee berries, remove the pulp, and soak the coffee beans in water for 36 hours to ferment the coffee beans. The peel that is still wrapped on the coffee beans will be peeled off. After rough cleaning, the coffee beans are dried in the sun or in a dryer to remove the last layer of film, so that the coffee beans become "naked" coffee beans and are sorted according to their size.

It is packed in a unit weight of 60 kilograms each. Generally speaking, the quality of wet-processed coffee beans is better than that of dried coffee beans.

The process of screening coffee beans, using manual work like the one described above, or machine screening, can select high-quality coffee beans without mixing immature or poor-quality beans. Countries that grow high-quality coffee varieties have long had advanced equipment to screen out the perfect coffee beans. Coffee bean processing: coffee berries must be processed immediately after picking to prevent pulp fermentation and decay. Coffee beans can be processed in two ways, wet and dry.

Drying method

The drying method is also called "natural method". Spread the coffee berries flat in the sun to dry. In the plantation, 50 square meters of coffee berries are spread on each hectare, or the fruits are dried in a special dryer. Put the dried coffee berries into two rollers (vats) to separate the coffee beans, and then sieve the type of device to separate the coffee beans from the endocarp. Finally, similar beans are screened out according to the shape and size of coffee beans, packaged and put on the market. In the final screening process, round beans (Perla / caracolito) will be selected and sold separately.
