First, coffee beans are placed in the mill case 3 and each part is set as shown in FIG. 1. Then, the motor 2 is energized and the cutter 4 is rotated at high speed, so that the coffee beans are ground by the cutter 4. When grinding starts, the astringent skin 12 of the coffee beans shown in FIG.
and the fruit 13 separate, and both become thinner with the passage of time.

When the extremely light astringent skin and fine powder of the fruit reach the end E of the guide 10, the direction is changed by the airflow flowing from chamber B to A through the peripheral communication hole H, and the defective components are carried into chamber A. It will be done. The airflow flowing into the chamber A returns to the chamber B through the central communication hole K of the partition plate 8, forming a circulation flow, but the airflow after passing through the peripheral communication hole H is decelerated, and the airflow returns to the chamber B through the central communication hole K of the partition plate 8. Due to the annular wall 14 around the hole K, defective components such as astringent skin do not return to the chamber 13 and accumulate in the chamber A, so that the defective components are continuously separated into the chamber A during operation, that is, while grinding the coffee beans. Can be captured.

Even when the large particulate coffee powder required for extraction of coffee liquid reaches the end E of the guide 10, its inertia continues to move in the same direction as the rotation of the cutter 4, and it is carried into the chamber A by the air flow. It is deposited at the bottom of chamber B without any problem.

According to the above configuration, the astringent skin and fine powder of the coffee beans can be efficiently separated and captured by the air flow generated by the rotation of the cutter 4 when the coffee beans are ground into the partitioned space A, which improves the deliciousness of the coffee. Since it is possible to remove unnecessary defective components, the taste of coffee can be further improved, and in particular, the difficult and troublesome work of removing defective components from the ground coffee powder is unnecessary. The convenience is great.

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 chamber B, so that the air flow led from the chamber B to the cylinder 9 passes through the cylinder 9. The centrifugal fan effect of the impeller 5 can be greatly enhanced by being guided to a position above the impeller 5. In addition, since a shielding guide 11 is provided below the peripheral communication hole H of the partition plate 8, the coffee particles blown away by the cutter 4 and the impeller 5 directly flow into the chamber A immediately after the start of coffee bean grinding. The air flow from chamber B to chamber A through the communication hole H can be made smooth without flying into the air, and defective components can be efficiently captured. Furthermore, since the coffee beans in the chamber B are stirred by the guide 10 from the outside toward the center, there is an effect that the coffee beans are ground uniformly.

The embodiments clarified by the above explanation do not indicate any structural limitations of the present invention, and in short, the present invention has a partition wall in the mill case on the side opposite to the cutter installation space in the cutter axial direction. A space is provided that is partitioned into two spaces, and a communication hole is provided between the periphery and the center of the partition wall, and the opening edge of the center communication hole on the side of the cutter installation space is extended into a cylindrical shape so as to face a position directly above the cutter. Any configuration is sufficient as long as the cutter is not provided with a blade wheel, and the defective components are sent to the partitioned space and separated and captured by the centrifugal fan effect accompanying the rotation of the cutter itself.

As explained above, the present invention provides a space in the coffee mill that is separated from the cutter installation space, and uses the centrifugal fan effect of the cutter that rotates during coffee bean grinding to cause the astringent skin and fine powder in the coffee beans to be stored in this space. Since the defective components are sent and separated and captured, the defective components can be easily and reliably removed, and a more delicious coffee liquid can be obtained from the coffee powder from which such defective components have been removed.

In particular, according to the present invention, since the partition wall that partitions the space for capturing defective ingredients is provided with a communication hole between the space and the cutter installation space, it can be constructed by simply installing the partition wall inside the mill case, and the coffee mill can be placed inside the coffee mill. It has the advantage of an extremely simple structure, such as not having to attach a separate case for capturing defective components. or,
By providing the above-mentioned communication holes at separate positions between the periphery and the center of the partition wall, and by opening the center communication hole directly above the cutter, the air flow caused by the cutter can be transferred between the two spaces. It has the advantage of being able to circulate efficiently, further improving the centrifugal fan effect of the cutter, and efficiently capturing defective components.
