DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crushing machine having a built-in crushing device in which a rice crushing device, a crushing device and a rice crushing device are provided adjacent to each other in addition to a crushing device, a sorting device and a rice milling device.に 関 す る It is related to a rice mill.

[0002]

2. Description of the Related Art In order to obtain polished rice from paddy, many steps are required, such as a step of converting rice into brown rice and a step of polishing brown rice. For self-milling, a so-called de-milling machine, which is capable of consistently performing from paddy to milling in one machine, is often used.

[0003] As shown in, for example, Japanese Utility Model Publication No. Sho 61-10755 and Japanese Patent Publication No. Sho 63-20175,
A series of devices such as a dewatering device, a sorting device, and a rice milling device are housed in one machine so that the integrated operation from hulling to milling can be performed by itself.

[0004]

However, the conventional rice milling machine does not have a built-in stone milling machine required in the process of milling and milling due to difficulty in assembling. For this reason, polished rice from the polished rice mill is passed through a separate destoner to remove stones mixed in the polished rice.

[0005] In such an operation, the rice heated by the milled rice is rapidly cooled by the air for destoning, so that many cracked rice and broken rice are generated, and it is inevitable that the quality and taste deteriorate. In addition, since the brown rice mixed with the stone is supplied to the rice mill, there has been a problem that the stone damages the rice mill net and the like.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems in the conventional rice milling machine. In addition to the milling machine, the air sorting machine and the rice milling machine, the stone milling machine and the rice milling machine are combined into one. Incorporating it into the airframe to make it compact and finishing the de-stoning work at the stage of brown rice after removal, so that the high-quality de-stoned brown rice can be supplied to the rice milling machine,
Good quality, good-tasting polished rice can be obtained consistently
And it was made possible to prevent the breakage of the rice milling equipment,
The aim is to provide a rice milling machine with a built-in stone removal device.
