[0009]

【Example】

 An embodiment of the present invention will be described below based on an embodiment of a coffee mill shown in the drawings.

In FIG. 1, the lower end opening of the hopper section 2 is connected to the coffee bean supply port 3 a of the introducing member 3, and the fixed blade 4 is fixed to the lower side of the introducing member 3 so as to face the lower side thereof. And a rotary blade 5 is provided. Then, coffee beans are configured to be supplied between the rotary blade and the fixed blade, and the discharge tube 7 extends downward from the outlet 6 in the outer periphery of the facing portion between the fixed blade 4 and the rotary blade 5. To be done. Further, a corona discharger 8 is fitted into the discharge tube 7, an insulating main body 8a of the discharger 8 faces the discharge tube, and the discharger 8 is connected to a high voltage DC source 9 installed in the casing 1. It

As shown in FIGS. 2 and 3, the main body 8a of the discharger 8 has a rectangular parallelepiped block shape, has an overhanging portion 8g on the upper portion thereof, and has four discharge electrodes protruding from the front surface thereof. Two diagonal lines are arranged at the apexes of a quadrilateral, and two diagonal lines are anodes 8b and two diagonal lines are cathodes 8c.

[0012] In order to prevent discharge between electrodes, a shielding wall 8d higher than the height of the electrodes is provided so as to partition adjacent electrodes, and other portions are less likely to accumulate powdery particles and are easy to clean. As described above, a groove 8e continuing from the wall as a smooth surface or a low flat surface (shown in phantom) is formed.

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 detachably attached by penetrating the side wall of the discharge cylinder 7 with its front surface (discharge surface) facing downward or obliquely downward. That is, the upper side of the inclined portion 7a is opened in a rectangular shape at the boundary between the inclined portion 7a and the hanging portion 7b of the discharge tube 7, and the mounting seat 10 is integrally formed around this. The mounting seat 10 is composed of a rectangular ring-shaped main body 10a and brackets 10b provided on the outer side in the radial direction of rotation of the rotary blade 5 so as to be opposite to each other. Then, the corona discharger main body 8a penetrates the opening, and the protruding portion 8g is supported on the upper surface of the mounting seat main body 10a. After that, the upper surface of the corona discharger projecting portion 8g is pressed downward by the pressing member 11 and attached. In the pressing member 11, brackets 10b are bent downward from both ends of a strip-shaped main body 11a provided on the upper end of the mounting seat bracket 10b, and contact pieces 11c are formed on the corona discharger side of these brackets. Then, the bolt 12 is screwed through the brackets 10b and 11b to be attached.

The operation state will be described above. When coffee beans are put in the hopper section 2 and the rotary blade 5 is rotated, the coffee beans are crushed between the fixed blade 4 and the granular material is guided from the outlet 6 to the discharge tube 7 and falls. Ion generation efficiency is good by DC corona discharge of the discharger 8, and bipolar ions are individually generated, and balanced ion is irradiated to the static elimination target, and highly efficient static elimination according to the charge polarity of the static elimination target object. You can

[0016] Although powder particles are less likely to adhere to and accumulate on the discharge surface of the main body 8a of the discharger, when cleaning, the bolt 12 is removed to remove the pressing member 12, the main body 8a is extracted, and the front surface thereof is brushed. Etc.

FIG. 4 shows another embodiment. The insulating body 8a 'has an annular shape, and two or more even-numbered discharge electrodes 8b' and 8c 'project on the inner peripheral surface of the insulating main body 8a' at substantially equal intervals on the same circumference. The insulating body is connected to a high voltage source through a high electric resistance in the insulating body, and the insulating body is detachably attached to the hanging portion 7b of the discharge cylinder 7 in a substantially concentric manner. 8d 'is a shielding wall and 8e' is a groove. Alternatively, the hanging portion itself of the discharge tube may be made of an insulating material, and the discharge electrode may be projected on the insulating material. Alternatively, each discharge electrode may be provided so as to protrude from the lower portion of the discharge tube via a separate insulating piece.

An AC power supply may be used instead of the DC power supply. In addition to coffee beans, the present invention can be applied to a crusher for spices such as pepper, grains such as rice, wheat and soybeans, and dried vegetables such as dried vegetables.

The present invention is not limited to the above-described embodiments and embodiments, and includes various modifications without departing from the spirit and scope of the utility model registration request.

[Effect of the device]

 According to the first configuration of the present invention, a corona discharge atmosphere is efficiently generated, and it is difficult for dust particles to collect on the discharge surface of the insulating body, and even if they do collect, cleaning is extremely easy.

With the second configuration, in addition to the effect of the first configuration, a discharge atmosphere can be obtained over a wide range.

According to the third configuration, the falling particles collide with the discharge electrode, so that a so-called self-cleaning effect is obtained in which the particles are unlikely to adhere and grow. It also has the effect of preventing finger insertion from the outlet of the discharge tube into the part such as the rotary blade. Further, since the adjacent gap between the discharge electrodes can be widened, the discharge between the electrodes can be prevented.
