Description

Home Rice Pottery {Polish rice by pounding machine}

The present invention relates to a domestic potter, and more particularly, by improving the structure of the bottom rice outlet of the guide cylinder configured in the minute adjuster of the household pottery to adjust the suction force of the collecting means connected to the guide cylinder and the suction hose,

According to the condition of the collecting means, the slide plate inserted into the slide groove of the bottom opening of the rice outlet can be expanded and reduced to adjust the suction force of the suction fan of the collecting means to completely collect the fine dust generated in the guide cylinder and the rice outlet during the cutting. An improved form of home pottery is provided.

In general, after harvesting rice, rice is obtained through rice milling process, such as white rice and brown rice, which are used at this time. The rice mill is generally used to separate rice and rice bran and rice bran through rice milling process. At this time, the separated white rice, rice bran and rice bran are discharged into the collecting tank and the rice bran through the respective passages.

When rice is cooked with brown rice or white rice, and the rice is eaten for a long time, the taste of rice is significantly reduced. At that time, the amount of rice needed to make rice to cook the situation.

Therefore, the home pottery is made compact and can be eaten at that time as much as needed in a normal home, so the taste of rice is much superior to that of a conventional pottery plant and then purchased and eaten for a long time.

In the structure of a general home pottery, rice supplied to a hopper is supplied to a potter's wheel by screws of a potter's wheel in a supply space part. Here, a tubular network is installed at regular intervals from the outer circumferential surface of the steel shaft. As the steel shaft rotates, the rice bumps against the steel mesh and peels the rice.

At this time, it controls the degree of rice being infested by the minute adjuster installed in front of the cutting shaft. In this way, white rice, rice bran and rice bran are separated from rice, and white rice is discharged into the rice container through the rice draining board, while rice bran and rice husk are discharge hopper. By operating the suction fan connected to the rice bran is collected in the rice bran via the discharge hopper and discharge pipe.

Looking at a home potter in accordance with the prior art,

The brown rice purifier of Korean Patent Publication No. 10-2003-27357 has a predetermined accommodation space and a housing having a hopper configured to supply rice to the upper portion;
