Description

Technical Field

[0001] The invention relates to the technical field of coffee powder processing, in particular to a device for ultrafine grinding, quantitative grading and packaging of coffee powder. Background Art

[0002] Coffee powder processing refers to the process of converting roasted coffee beans into powder through a grinding process. This process usually includes the unit operations of coffee bean screening, impurity removal, roasting, cooling, grinding and packaging. The coarseness of the grinding will vary according to different coffee making methods to ensure that the final product can meet specific brewing requirements. In the processing process, the grinding of coffee beans is the most critical step, because coffee powder is easy to oxidize and the aroma will escape. Especially when the storage conditions are not appropriate, the coffee powder is also easy to oxidize and become rancid, affecting the flavor of the final product. Therefore, the ideal time to grind coffee beans is before brewing to maintain the best flavor of coffee. Coffee powder processing is an industry with a long history.

The rotation of the first rotating motor 206 can drive the rotating shaft 207 and the rotating plate 209 at the bottom to rotate. Under the action of the rotation of the rotating plate 209, the cleaning cover 210 below can be driven to rotate, so that the coffee beans inside the cleaning cover 210 can be quickly cleaned.
