Description

Technical Field

[0001] The utility model relates to the technical field of coffee processing, in particular to a coffee quality screening device. Background Art

[0002] Coffee beans refer to the fruit of the plant used to make coffee. Broadly speaking, there are two kinds of coffee beans in the world, Arabica beans and Robusta beans. The coffee fruit is composed of two oval seeds facing each other. The side that connects to each other is a flat surface, which is called a flat bean. But there are also beans composed of a round seed, called round beans, and their taste is no different. In order to obtain high-quality coffee beans, the coffee beans need to be graded, and the particle size of the coffee beans often determines the quality of the coffee beans. Therefore, it is very common to use a screening device to screen and grade the coffee beans. Nowadays, there are screening devices with fixed screens, and the screens cannot vibrate or move with the help of other structures, which greatly reduces the screening efficiency of the coffee beans. For this reason, we propose a coffee quality screening device. Utility Model Content
