成分を空間Aに分離捕獲できる。 However, when the extremely light astringent skin 12 and the defective components such as fine fruit powder reach the terminal end E of the guide 10, they change direction due to the air flow flowing from the space B to the space A through the communication hole H in the periphery. and is carried into space A. The airflow flowing into the space A returns to the space B through the communication hole K in the center of the partition plate 8, forming a circulating flow, but the airflow after passing through the communication hole H in the periphery is decelerated. and the first annular wall 14 on the periphery of the communication hole K in the center and the second annular wall 14 on the outer periphery of the partition plate 8.
Due to the annular wall 14', defective components such as astringent skin are removed from the communication hole K and the gap between the partition plate 8 and the mill lid 7 in the space B.
In other words, defective components can be continuously separated and captured in space A while grinding coffee beans during operation.
なお、コーヒー液抽出に必要とする大きめの粒

面が平坦である故清掃廃棄がし易い。 After grinding the coffee beans as described above,
The mill lid 7 is removed from the mill case body 3 and the particulate coffee powder inside the mill case body 3 is taken out and used. On the other hand, defective ingredients such as astringent skin and fine powder captured in the space B are removed from the mill lid 7 by the partition plate 8. Just remove it, clean it and dispose of it. At this time, the first and second annular walls 14, 14' are provided only on the side surface of the space A of the partition plate 8, and the side surface of the space B is flat, making it easy to clean and dispose of.

という効果もある。 According to this embodiment, the central communication hole K is configured to open directly above the cutter 4 through the cylinder 9 with respect to the space B, so that the centrifugal fan effect of the impeller 5 can be greatly enhanced. can. Also, partition plate 8
Since a shielding guide 11 is provided below the peripheral communication hole H, the coffee particles that are blown away by the cutter 4 and the impeller 5 after the start of coffee bean grinding may not directly jump into the space A. Therefore, the air flow from the space B to the space A through the communication hole H can be made smooth, and defective components can be efficiently captured. Furthermore, since the coffee beans in the space B are stirred by the guide 10 from the outside toward the center, there is also the effect that the coffee beans are ground uniformly.
