Specific introduction to the production of coffee beans

After harvest, peel, pulp, racing peel and silver peel should be removed before shipping and listing. There are two kinds of methods: drying (also known as natural or non-washing) and washing.

Dry type:

The method is relatively simple. First of all, spread the freshly harvested fruit on the sun field for a week or two until the fruit crackles and dries naturally. After that, the dried pulp, endocarp and silver peel are removed by a sheller.

Coffee beans refined in this way are slightly sour and slightly bitter. All coffee beans from Brazil, Ethiopia, Yemen and other places are obtained in this way. The disadvantage of this method is that it is easily affected by the weather and is easy to be mixed with defective beans and other impurities. Therefore, it must be carefully screened.

Washing type:

The fruit that is about to be harvested is put into a flowing trough. After the floating fruit is removed, the skin and flesh are removed by a pulp remover. Then put it in the sink to remove the emerging pulp. After that, move into the fermentation tank, soak for half a day to a day, and then dissolve the gum on the surface of the fermented coffee beans.

After washing with water, drying it for a few days, drying it with a machine, and finally using a sheller to remove the endocarp to become a commercial raw coffee bean. In this way, it will be more beautiful in color and less impurity than dried coffee beans. Colombia, Mexico, Guatemala and other countries use this method for about 70% of their production.
