Description

Technical Field

[0001] This utility model is a coffee bean color sorting and destone removal device, belonging to the field of coffee bean color sorting technology. Background Technology

[0002] Coffee beans refer to the fruit of the plant used to make coffee. Broadly speaking, there are two types of coffee beans in the world: Arabica and Robusta. The coffee fruit consists of two oval seeds facing each other. The side where they meet is flat and called a flat bean. However, there are also beans composed of a single round seed, called a round bean. The taste is identical. During the coffee bean production process, color sorting is required to remove substandard beans and impurities.

[0003] Existing technologies lack equipment for color sorting coffee beans. Most coffee beans are sorted using conventional screening machines. Although these machines can sort coffee beans, smaller beans are mixed with sand and other impurities after sorting, requiring a second color sort. Utility Model Content
