Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice-milling machine for polished rice, which is used particularly in ordinary households and enables polished rice to be cooked with anhydrous rice. .

2. Description of the Related Art Some conventional rice-milling machines of this type are designed to continuously perform browning and polishing of brown rice.

 An example will be described with reference to FIG.

In FIG. 6, reference numeral 21 denotes a brown rice tank, and a grain feeding room 22, a rice polishing room 23, and a polishing rice room 24 are sequentially connected to an opening at the bottom thereof. Reference numeral 25 denotes a rotating shaft, which is rotated by a driving shaft 26. A feeding spiral 27 having a spiral for transporting brown rice is formed in the grain feeding room 22.
However, the milling room 23 has a milling trochanter 28 formed with milling wings 33 for milling brown rice, and the milling room 24 has a ratchet wheel-shaped milling body 29 for milling milled rice. I have. 30 is the polishing room 24
Is provided with a pressure regulating valve 31 which can be closed. Reference numeral 32 denotes a cylindrical body, which covers the grain-feeding room 22, the rice-milling room 23, and the rice-grinding room 24.

Put brown rice into the brown rice tank 21 of the rice polishing machine with the above configuration,
When the rotating shaft 25 is rotated by the drive shaft 26, the brown rice
As a result, the rice is transferred downward through the grain-feeding room 22 and enters the rice-milling room 23, where the rice is polished by the friction caused by the stirring of the rice milling trochanters 28 and the frictional action between brown rice. The polished rice flows into the polishing rice room 24 and is polished by the polished rice body 29, pushes and opens the pressure regulating valve 31 from the polished rice outlet 30, and flows out of the outlet trough 34 into the container 35.

The above conventional rice milling machine continuously performs the milling of brown rice and the milled rice that has been milled. The rice is pressed strongly against the inner wall of the rice polishing room 24 on the back side of the tooth-shaped teeth to perform the rice polishing action, and the pressing force increases the frictional force between the rice grains to grind. Increases rice action.
Further, a pressure regulating valve 31 attached to a white rice outlet 30 provided in the polishing rice room 24 also increases the pressing force and contributes to the polishing rice operation.

Problems to be Solved by the Invention The method in which the rice polishing action is performed by such a pressing force is excellent in the rice polishing effect, but in order to obtain the pressing force, the polishing rice body 29 is naturally high in rigidity. Thus, there was a possibility that the milled rice was broken due to the pressing force during the polishing of rice and the incidence of broken rice was increased. In addition, since the rice is polished by pressing force, the skin of the polished rice wears more and the generation rate of bran and rice powder may increase, and the moisture content of the polished rice decreases due to the heat generated by friction between the polished rice and rice. There was a problem that there was a risk. For these reasons, there has been a demand for an excellent type of anhydrous rice polishing machine that does not immerse hands in cold water in winter.

Therefore, an object of the present invention is to make it possible to polish rice without generating a large pressing force and to easily and quickly remove generated powder.

Means for Solving the Problems In order to achieve the above object, the present invention provides a hopper into which rice can be put and a horizontally disposed hopper below the hopper, and rice from the hopper is connected to the hopper lower opening. An opening supplied through the provided introduction passage is provided on the outer periphery of one end,
A cylindrical rice-milling body made of a thin plate with a large number of rice-milling holes with rice-milling blades inward, and a rotatable interior inside this rice-milling body, with a space between each other on its surface A polishing body having a large number of flexible projections, a driving body for rotating and driving the polishing body, and an outer casing covering the rice polishing body, and being connected to a cylindrical portion of the rice polishing body. The introduction passage is provided with a powder discharge hole which does not have a rice-grinding blade in the inward direction, and the powder discharge hole has a size that cannot pass through the polished rice and is larger than the rice-grinding hole.

In the above-described configuration, the polished rice that has flowed into the polished rice body from the hopper is rolled by the flexible polished body and the polished rice body that are spaced apart from each other on the surface of the rotating polished body, and It is sandwiched between the flexible projection and the polished rice body and is moved in the inner circumferential direction of the polished rice body. Thereby, bran and the like adhering to the surface of the polished rice are quickly removed, and polished rice that can be cooked by anhydrous washing can be obtained. At the same time, the rice bran and the like present in the vicinity of the lower opening of the hopper are quickly discharged from the powder discharge hole, so that the rice bran and the like accumulate in the opening and grow to reduce the area of the opening. Nothing will happen if the supply to the lab rice room is poor.

By making the powder discharge hole larger than the polished rice hole, large refuse, dust, etc. which adhere to the rice surface and cannot be removed by the polished rice hole are removed before polishing.
