[0002] As people's living standards continue to improve, coffee, one of the world's three major beverages, has begun to enter the consumption list of the general public. Many areas in my country have also begun to introduce a large number of coffee trees for local cultivation, and the coffee processing industry, following the planting industry, has also developed vigorously. After the fresh coffee berries are picked, they need to go through the steps of fruit selection, peeling, drying, etc. before they can get the coffee beans used to make coffee. At present, the selection, peeling, drying and other processing of fresh coffee berries are mainly completed manually, which is not only inefficient and labor-intensive, but also requires a lot of human resources to ensure normal production. However, the commercially available coffee berry selection machines, peeling machines, dryers and other equipment have problems such as complex structure, inconvenient installation and debugging, and high purchase costs. Especially for the selection and peeling of fresh coffee berries, the selection machine is difficult to separate the high-quality berries from the floating berries and the shrunken berries, and there are problems such as low selection efficiency, large consumption of water resources, and excessive waste of water resources; the peeling machine often has problems such as unclean peeling or serious damage of coffee beans during peeling, resulting in a large number of reworks and serious waste of coffee beans. The above-mentioned situations will restrict the development of the coffee processing industry and pose a serious threat to the survival of small and medium-sized enterprises. Therefore, it is necessary to improve the existing technology. Summary of the invention
