In the case of such a pulverizer, most of them have a complicated structure with a screen or mesh for selecting the particle size, and there are hygiene problems when handling maintenance and foods. In many cases, heat generated during the grinding process is difficult to escape. In addition, in the case of a pulverizer having such a structure, there are many things in which heat is difficult to escape due to the complicated structure. In view of the above-mentioned problems, the present invention is not equipped with a screen, mesh, etc., has excellent maintainability, is easy to clean and has no sanitary problems, and has a simple structure that allows heat to escape to the outside, allowing selection of particle size. Technical problem is to provide a simple grinder.

In order to solve the above-mentioned problem, a rotation device is provided with a plurality of blades radially attached to the outer peripheral edge and rotated by the power of the drive motor, in addition to being arranged in a supply device for supplying raw materials and a supply device lower supply port The technical means is composed of a wing plate and a round case that houses the rotating wing plate.

In this way, since it has an extremely simple configuration, it solves the quality of maintenance and the sanitary problem when handling foods and the like.

In addition, the simple structure of collecting the pulverized material floating in the floating cylinder by the exhaust flow generated by the rotor blades solves the problem of quality of maintenance, hygiene problems, and particle size selection method. .

In addition, the front surface of the round case can be opened and closed, and this solves the quality of maintenance and the sanitary problem.

In addition, the heat is released by the exhaust flow from the rotor blades and the wind of the blower, thereby suppressing the deterioration of the raw material.

The solid material pulverizer of the present invention has an advantage that it can produce a savory powder while suppressing deterioration due to heat in the production process such as rice flour, soybean flour, and wheat flour.

In addition, since the structure is simple, maintenance and cleaning are simple, and there is an advantage in terms of hygiene when handling food.

The round case 8 is fixed by welding to the base 16 with the circular surface substantially vertical, and is installed. Further, the supply pipe 7 is attached to the round case 8 by welding at an appropriate position on the back surface. A rotor feeder 6 that is rotated by a drive motor (not shown) is attached to the upper portion of the supply pipe 7 by welding.

A supply hopper 5 for charging raw materials is attached to the upper portion of the rotor feeder 6.

The round closure lid 13 is supported by the round case 8 so as to be opened and closed by an opening and closing hinge 14 and is attached by welding. The round case 8 and the round closure lid 13 are closed by a fastening device such as a fastener or a clamp (not shown). In addition, an intake pipe 10 having an intake air amount adjusting valve or a damper (not shown) is attached to the round closing lid 13 by welding.

The rotary blade 1 is circular and has a diameter of about 90% with respect to the inner diameter of the round case 8. In addition, the rotary vane 1 has a square vane plate 2 having a side length of about 15% of the diameter of the round case. The rotary vane plate 1 is angled with respect to the radiation in order to generate an exhaust flow, and a plurality of the vane blades are equally spaced. A gap of several millimeters is formed between the outer periphery and the inner surface of the round case 8 and is attached to the rotor blade 1 by welding. Further, the rotary blade 1 is attached with a rotating main shaft 3 perpendicularly to the rotary blade 1 by welding or bolts and nuts to the center of the circle of the rotary blade 1.

The rotation main shaft 3 passes through the center of the back surface of the round case 8 and is connected to the drive motor 4 by a chain (not shown) and supported by a bearing unit (not shown).

The floating cylinder a9, the floating cylinder b18, and the connecting short pipe 12 are connected by bolts and nuts, and are attached to the discharge pipe 17 by bolts and nuts in an approximately vertical upward direction on the outer circumference of the upper half circle of the round case 8. Moreover, the floating cylinder b18 can be replaced | exchanged and the full length of the floating cylinder comprised by the floating cylinder 9 and the floating cylinder 18 can be changed.

A pulverized material discharge port 11 is installed at the top of the floating cylinder 9.

At the rear stage of the floating cylinder discharge port 11, a powder collecting device such as a cyclone or a dust collector (not shown) and a blower device such as a blower for applying a negative pressure to the floating cylinder are attached.

Next, the operation of the solid matter pulverizer of the present invention will be described. The solid matter put into the supply hopper 5 is put into the pulverizing section through the supply pipe 7 by the rotor feeder 6 rotated by a drive motor (not shown). The power of the drive motor 4 is transmitted by a rotary main shaft 3 supported by a bearing unit (not shown), and the rotary vane plate 1 on which the vane plate 2 is disposed is placed inside a space constituted by a round case 8 and a round closure lid 13. By the rotation, the solid material supplied by the above-described supply device is randomly beaten in the round case 8 to be crushed. The object to be crushed is floated in the floating cylinder 9 arranged substantially vertically upward on the outer circumference of the upper half circle of the round case 8 by the exhaust flow generated by the rotary blade 8 and the blade 2. At this time, the unground material is returned to the pulverizing part by its own weight and further pulverized, and only the finely pulverized material floats to the top of the floating cylinder. The object to be crushed suspended at the top of the floating cylinder is discharged from the floating cylinder discharge port 11 provided at the top of the floating cylinder by the negative pressure of a blower (not shown). The discharged material to be crushed is collected by a powder collecting device such as a cyclone or a dust collector (not shown).

As described above, the floating cylinder can be changed in total length. When the total length is increased, only the material to be crushed to a finer particle size floats at the top of the floating cylinder, and when the total length is shortened, the coarse particle size is increased. The material to be crushed also floats on the top of the floating cylinder and is collected by a powder collecting device, so that the particle size can be adjusted by the length of the floating cylinder, and can be selected and collected.

In addition, the intake air flow rate is adjusted by a valve or a damper (not shown) attached to the intake pipe 10 and the exhaust gas flow rate adjustment of a blower (not shown) attached at the subsequent stage of the floating tube discharge port 11 is placed at the top of the floating cylinder. It is possible to adjust the particle size of the floating object to be crushed and to select and collect the powder.

Grains such as rice, soybeans and wheat can be pulverized to produce powders of uniform particle size.
