Then, coffee beans are configured to be supplied between the rotary blades and the fixed blades, and a discharge tube 7 extends forward and downward from the outlet 6 at the outer periphery of the facing portion between the fixed blades 4 and the rotary blades 5. To be done. Further, a corona discharger 8 is fitted in the discharge cylinder 7, an insulating body 8a of the discharger 8 faces the discharge cylinder, and the discharger 8 is connected to a high voltage DC source 9 installed in the casing 1. .

As shown in FIGS. 2 and 3, the main body 8 of the discharger 8 is shown.
a has a rectangular parallelepiped block shape (solid short column shape) , has an overhanging portion 8g at the upper portion, and has four discharge electrodes protruding from the front surface thereof, and the discharge electrodes are arranged at the apex of a substantially right-angled quadrilateral. The two diagonal lines on one side are anodes 8b and the two diagonal lines on the other side are cathodes 8c.

In order to prevent discharge between the electrodes, a shielding wall 8d higher than the height of the electrodes is provided so as to partition adjacent electrodes.
The other portion is provided with a groove 8e continuing from the wall as a smooth surface or a low flat surface (shown in phantom) so that the particulates are hard to collect and can be easily cleaned.

A high resistance 8f (for example, 100 MΩ) is connected to the electrodes 8b and 8c in the main body 8a. This prevents the electric shock phenomenon.

In FIG. 5, the main body 8a is removably attached by penetrating the side wall of the discharge cylinder 7 with its front surface (discharge surface) facing downward or obliquely downward. That is, at the boundary between the inclined portion 7a and the hanging portion 7b of the discharge tube 7, the upper side of the inclined portion 7a is opened in a rectangular shape, and the mounting seat 10 is provided around this.
Are integrally formed. This mounting seat 10 is a rectangular ring-shaped main body 1
0a and a bracket 10b that is provided on the outer side in the radial direction of rotation of the rotary blade 5 so as to oppose each other on the left and right.
