Description

Multistage selection by winnowing grading plant of coffee beans

Technical Field

The utility model belongs to the technical field of biological fermentation, and particularly relates to a multistage air separation and classification device for coffee beans.

Background

After the fresh coffee fruits are picked from the coffee trees, the fresh coffee fruits are firstly processed by a plurality of procedures of cleaning, peeling, degumming, drying, storing, shelling, polishing and the like, and then are baked to form the coffee baked beans which can be bought in the market. The four processes before roasting of coffee beans generally have two processing methods, namely a dry method and a wet method, and the selected method has great influence on the quality and the commodity value of the final product of coffee.

The air separation is a method for removing impurities by wind power by utilizing the difference of the suspension speed between materials and impurities. The aim of air separation is to remove light impurities and dust and also remove part of stone, soil block and other heavy impurities, and the method is commonly used for cleaning crops and removing dust and foreign matters in the industries of grain, tobacco and the like;

coffee beans are water-washed and dried, flat and round. The coffee beans are dark and light in color, and by deep roasting, the coffee beans pop open, doubling in volume, and reducing weight by approximately 1/4. The coffee beans gradually generate volatile flavor oil in the baking process, so that various flavors are perfectly balanced. Even in the same producing country, the coffee beans have subtle influences and the flavor and quality of the coffee beans and the characteristics of the coffee beans are generated due to the difference of climate, altitude and soil property of each region. In the processing process of coffee rice, the coffee rice needs to be sorted, but the existing winnowing machine has poor winnowing effect.
