The primary processing of coffee is a crucial part of the development of the Yunnan Arabica Coffee industry chain. The quality of green coffee beans after primary processing directly affects the transaction price and sales prospects of commercial coffee beans. Coffee has different initial processing methods and numerous technological links, including separating and classifying green and red coffee cherries, peeling, degumming, drying, and shelling. The required processing technology is complicated, and the processing of each step affects the final coffee quality. To this end, the applicable conditions of various processing methods are introduced in detail. The development status of domestic and foreign coffee primary processing methods and comparative analysis are described. Combining with the unique local environment in Yunnan and looking forward to appropriate development trends, it is proposed to promote the mechanization of coffee primary processing on a large scale, explore the research and application of microbial degumming and artificial drying technology, pay attention to the research and development of energy-saving, water-saving, environmentally friendly and pollution-free processing technology and equipment. In addition, it is also necessary to improve the standardization of coffee primary processing operational procedures and strengthen the storage and transportation of coffee beans.
