Description

Technical Field

[0001] The utility model relates to the technical field of coffee bean processing, in particular to a shelling device for processing raw coffee beans. Background Art

[0002] The hulling unit is a crucial step in the coffee bean processing process. It removes the outer skin and inner membrane of the coffee fruit, extracting the raw coffee beans. Using efficient physical or mechanical methods, the hulling is removed, ensuring the quality and cleanliness of the green beans, preparing them for subsequent roasting and processing.

[0003] A shelling device for processing raw coffee beans disclosed in Chinese patent publication No. CN211217528U has a first baffle and a second baffle. The first baffle and the second baffle are hollow, allowing objects the size of the shell to pass through, but not allowing coffee beans to pass through. While ensuring the collection of the coffee bean shells, it can also prevent the coffee beans from accidentally entering the interior of the air duct. When the coffee beans fall and hit the first baffle or the second baffle, they have a certain kinetic energy and can therefore be blocked by it and bounce back onto the vibrating screen, which can avoid waste of raw materials. However, the shelling device for processing raw coffee beans has low functionality, and the internal coffee beans cannot be fully and effectively shelled, resulting in some coffee bean shells adhering to the outer surface of the coffee beans, thereby affecting the subsequent coffee bean roasting quality.
