Description

Multistage sorting unit of coffee fruit

Technical Field

The utility model relates to the technical field of coffee fruit sorting, in particular to a multi-stage sorting device for coffee fruits.

Background

Coffee cherries are the raw material for producing coffee beans. After the coffee cherries are picked from the coffee tree, the coffee cherries are firstly processed through a plurality of procedures such as peeling, degumming, drying, storage, shelling, polishing and the like, and then baked to obtain the common coffee beans on the market. These four steps before roasting of coffee beans generally have two processing methods, namely a dry method and a wet method, and the selected methods have a great influence on the final product quality and commodity value of the coffee.

The quality of the coffee beans themselves is fundamentally affected by the quality and commodity value of the final coffee product. Among them, the size of the coffee beans is the most affected, and although the size of the coffee beans is not directly representative of the quality of the coffee beans, the content and quality of caffeine, tannins, proteins, fats and sugar contained in the large coffee beans are generally superior. Small coffee beans may have a poorer growing environment than large coffee beans, resulting in a less important quality and an affected content of the main components of the coffee beans.

The size of the coffee cherries directly determines the size of the coffee beans. Therefore, it is also important to sort the coffee cherries before processing the coffee cherries, and the conventional coffee fruit sorting device cannot sort the fruits finely enough, but cannot sort the fruits in multiple stages, which affects the subsequent processes.
