A grinding rice blade that grinds rice by friction with a polishing surface formed on the back surface of the rotating blade and simultaneously pushes the rice downward, An output shaft for rotating the stirring rice wing,
In a rice mill comprising a rice container for accommodating the agitated rice wings, and a mesh surface formed on the lower surface of the rice container to separate bran downward while polishing, a draft is blown downward from above in the rice mill. In addition to providing a cooling ventilation means, the agitated polished rice blade is formed by a punched wire mesh. As a result, the flow of the air flowing into the rice mill can be promoted, and the rice heated in the rice mill can be effectively cooled. It can be milled into rice.

The structure of a rice milling machine disclosed in Japanese Patent Application Laid-Open No. Hei 1-199652 is described below. A mesh container having a mesh and a polished surface formed inside a rice container body for separating bran while polishing is arranged in association with the rice mill. Forming a flow passage for bran and air between the rice container main body and the mesh container, and simultaneously pushing downward while grinding rice in the mesh container by friction with a polishing surface formed on a rotating blade. This is the one in which the agitated grinding rice wing is arranged. Thus, the heated rice can be cooled by the air flowing into the rice container into the polished rice, thereby reducing the broken rice ratio and easily discharging the produced bran in a short time.

[Problems to be Solved by the Invention] The above-mentioned Japanese Patent Publication No. 3-412
According to the rice milling machine disclosed in Japanese Patent No. 17, the cooling ventilation means, which blows air downward from above in the rice mill, is connected to an air inflow propeller fixed to the upper part of the rotating shaft and / or a bran discharge part below the rotating shaft. Since it is composed of a fixed air discharge propeller, the structure inside the rice container is complicated, and the production cost is high.

According to the rice milling machine disclosed in Japanese Patent Application Laid-Open No. Hei 1-1199652, since a brass and air flow passage is formed in a power section having a built-in motor, in the case of sticky bran, There is a risk that the bran will stick to the flow passage and cannot be removed only by blowing air. If this is left for a long time, a bran odor is generated, which is unsanitary, and the flow passage must be washed with water or the like. The flow passage itself is fixedly integrated with the power unit containing the motor.To clean this part, it is necessary to remove screws and the like to disassemble the power unit and the flow passage, which is troublesome. there were.

In view of the above problems, the present invention has a structure in which the container main body and the bran collecting container are detachable from a power unit having a built-in motor, so that maintenance after use, such as washing with water, can be easily performed after the completion of the polishing.

Next, the operation of the household rice mill according to the present invention in the above configuration will be described. When grinding rice to be eaten at home in the range of one go to several go, remove the lid 5 and put brown rice weighed with a measuring cup etc. from the opening surface of the mortar container 4, and the brown rice will be used for bran removal It is stored in the cylindrical portion 7 of the porous wall 6. At this time, since the inner diameter of the cylindrical portion 7 is formed relatively small, even a small amount of brown rice does not accumulate in a thin layer, and has a layer thickness that is high enough to hide the stirring projection 13. Is deposited. Next, the cover 5 is fitted into the mortar-shaped container 4, the amount of sticking is set by a sticking amount switch (not shown) of the operation panel 21, and a whiteness setting switch (not shown).
Then, the operation switch (not shown) is turned on to start milling. Then, a signal for setting the number of rotations and the driving time of the motor 3 is output from a control device (not shown), and the result is transmitted to the motor 3. For example, when the sticking amount is set to “one go” and the whiteness is set to “white rice”, the rotation speed is set to 2,400 rpm and the driving time is set to 90 seconds.

When the torque of the motor shaft 26 is transmitted to the longitudinal axis 16 via the belt 19 by the motor 3, the joint 26,
It is transmitted to the longitudinal axis 12 in the mortar container 4 via 14. As a result, the stirring protrusion 13 mounted on the vertical axis 12 rotates. However, since the stirring protrusion 13 is deposited so as to be almost hidden by the introduced brown rice, sufficient polishing power is given. Become. This milling state will be described.

It is thrown up on the inclined surface (porous wall 6 for bran removal) of the shaped container 4. As a result, the rice grains form a large circulation locus in the mortar-shaped container 4 and are polished (see the locus indicated by the broken line in FIG. 3). ) Decreases, and the finished whiteness becomes the same as the set whiteness.

When the motor shaft 26 is rotated by the motor 3, the blower fan 32 is rotated, and external air is taken into the mortar container 4 through the air inlet 27, the air guide path 29a and the air guide path 31a. Can be Since this external air easily flows in from the flow passage 35a provided in the lid 5, the rice grains heated by polishing rice in the mortar-shaped container 4 can be cooled, and the incidence of broken rice can be prevented. Further, even if the temperature of the air in the mortar container 4 rises, the inside of the mortar container 4 is cooled by the inflow of external air, and the lid 5 is closed.
The occurrence of dew condensation on the inner surface can be prevented.

The air flowing into the mortar container 4 is
5b, the air is exhausted to the outside through the exhaust path 31b, the blower fan 32, the exhaust path 29b, and the air outlet 28. At the same time, the motor 3 heated by the suction of the air by the blower fan 32 can be cooled.

When the driving time has elapsed and the milling is completed, the lid 5 is removed as shown in FIG. 4, and the mortar-shaped container 4 and the bran collecting container 5 are removed from the base 2 by holding the flange 10A by hand. You can carry the milled white rice. Also,
Since the mortar-shaped container 4 and the bran collecting container 5 can be separated, the bran can be taken out from the bran collecting container 5 when using the bran for food, and the maintenance such as washing with water after use is easy. It can be carried out.
