Description

Technical Field

[0001] The utility model relates to the technical field of cleaning devices, in particular to a coffee fresh fruit cleaning device. Background Technique

[0002] After coffee fresh fruits are picked from coffee trees, they first need to go through multiple processes such as peeling, degumming, drying, storage, shelling, and polishing, and then become the coffee beans that we can buy in the market after roasting. In the degumming process of coffee beans, a large amount of water is required to clean the coffee beans. Since the coffee beans are still wet coffee beans during the degumming stage, in order to facilitate the subsequent processing of wet coffee beans, during the degumming and cleaning stage of wet coffee beans, the wet coffee beans are screened and graded while being degummed and cleaned.

[0003] After retrieval, the patent with publication number CN215124187U discloses a coffee fresh fruit cleaning device for preventing damage to fresh fruits. In this solution, a rotating shaft ring and a gear sleeve are arranged between the upper plate and the lower plate, which can be combined with a gear to drive the mechanism to rotate, so as to clean the coffee fruits. A fixed shaft and a brush are arranged in the wire cage to brush the coffee fresh fruits, making the cleaning more thorough. At the same time, the brush can prevent the coffee fresh fruits from being damaged during the cleaning process.

[0004] However, in the above solution, except for the brush part, the coffee fresh fruit brushing structure is made of metal. During the cleaning stage of coffee fresh fruits, there will still be a situation where the coffee fresh fruits collide hard with the brushing structure and are damaged, and no coffee fresh fruit screening structure is set, which causes inconvenience to the subsequent processing of coffee fresh fruits.

[0005] Therefore, a coffee fresh fruit cleaning device is proposed, which has the advantages of low-damage cleaning and discharging and screening, so as to solve the problems in the above background technique. Content of the Utility Model
