2.1 Coffee processing technology and equipment can not meet the standard quality production standards

Yunnan coffee is mostly mountain coffee, and it has the characteristics of scattered plantations, small production scale and mainly farmers, so the users of coffee processing equipment are generally small family workshops, and there are few processing enterprises with certain economic strength and scale. The development of domestic coffee primary processing machinery is to adapt to the local coffee production scale, topographic characteristics, production status, processing technology and the economic strength of users, so the equipment is simple, the mechanical matching is poor, and the machining precision is low. Coffee initial processing technology and equipment does not have a full set of standardized equipment configuration production standards and capabilities from fresh fruit picking to export.

2.2 Coffee professional processing machinery research is less, production technology, independent innovation ability is low

The development of scientific research and production of coffee processing machinery in China is slow. In the early stage of coffee planting, artificial peeling is used. Since the 1970s, scientific research and production units have gradually carried out research on processing machinery, mainly peeling machines and shelling machines. In recent years, domestic coffee processing equipment is generally mixed with imported Brazilian equipment, Colombian equipment and domestic equipment. Domestic equipment is mainly peeling machine, degumming machine and degumming machine produced by Yunnan Baoshan Agricultural Machinery Factory, Yunnan Agricultural Machinery Research Institute and Fumin Machinery Factory. The price of this kind of machinery is low and small, but the matching is poor and the degree of innovation is not high.

2.3 imported coffee processing machinery does not link up with supporting processing technology

Take the coffee mechanical degumming and cleaning machine as an example, mechanical degumming can effectively avoid the traditional fermentation degumming degree is not easy to control, resulting in discoloration beans and other problems, so as to reduce the defective rate and improve the economic value of the product. However, in the actual production, this kind of machinery imported and purchased by some enterprises has encountered idle, because the beans after mechanical degumming are easy to stick to the cement floor of the drying field in the natural drying process, and it is easy to damage the coffee seed shell during the manual turning process, affecting the quality of coffee. There are also some imported drying equipment that can not achieve the expected production effect because of unfamiliar operation.
