(transfer) coffee initial processing

There are many initial processing methods of coffee, which are mainly divided into dry processing, wet processing and semi-dry processing. Here we briefly introduce the first two processing methods.

1. Dry processing (dry process): the fresh coffee fruit is dried into dried fruit, and then the dried peel is removed mechanically to prepare raw coffee.

2, wet processing (wet process): coffee fruit in water medium, after mechanical peeling, fermentation and then mechanical friction degumming, and through washing, drying processing.

The purpose of initial processing of coffee

After coffee is picked, it takes a series of treatments to get commercial raw coffee (green coffee; raw coffee), that is, coffee beans (coffee bean).

Coffee bean (coffee bean): trade name for dried coffee seeds that have been stripped of their silver skins.
