DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a semi-succeeded rice returning device of a rising rice mill.

(Prior Art) In Japanese Patent Laid-Open No. 59-39349, a motor is provided at a lower position in a case, an upper feed spiral is provided at a lower position of a vertical axis rotated by the motor, and an upper feed spiral is provided above the spiral. A rice mill roll is attached to the upper feed spiral, and the outer circumference of the upper feed spiral is surrounded by a shell tube. The outer circumference of the rice mill roll is surrounded by a perforated cylinder, and a supply port is formed at a lower position of the shell shell to supply the outside. It describes a rising type rice milling machine in which a hopper is attached, a discharge port is formed at an upper position of the perforated cylinder, and a load resistance device is provided at the discharge port.

Further, in the publicly known Japanese Patent Application Laid-Open No. 62-110752, there is described a technique for returning the semi-polished rice discharged from a downflow type rice mill instead of the upright rice mill to polish the rice.

(Problems to be Solved by the Invention) The one described in Japanese Patent Laid-Open No. 62-110752 relates to a downflow-type rice milling machine, which is based on the semi-polished rice discharged from the downflow-type rice milling machine. It is a technique for returning and processing, but it has a considerably complicated configuration.

The one described in Japanese Patent Laid-Open No. 59-39349 is an ascending type rice milling machine, but a technique for returning the semi-polished rice to the original state is unsolved.

(Object of the Invention) The present invention provides a rising-type rice milling machine with a simple structure that allows half-steamed rice to be returned to the original state for processing.

(Means for Solving the Problems) Therefore, according to the present invention, the motor 2 is provided at the lower position in the case 1.
Is provided, an upper feed spiral 3 is provided below the vertical axis rotated by the motor 2, and a rice polishing roll 4 is provided above the spiral 3.
The outer circumference of the upper feed spiral 3 is surrounded by a shell shell 7, the outer circumference of the rice polishing roll 4 is surrounded by a perforated cylinder 8, and a supply port 9 is formed at a lower position of the shell shell 7. A supply hopper 10 is attached to the outside, a discharge port 11 is formed at an upper position of the perforated cylinder 8, and a load resistance device 12 is provided at the discharge port 11, and a switching valve 1 is provided outside the discharge port 11.
5, a polished rice extraction trough 13 and a half-and-half rice return port 16 are formed, and the half-and-rice return port 16 is positioned higher than the supply hopper 10, the half-rice return port 16 and the supply hopper 10. This is a half-steamed rice returning device of an ascending-type rice milling machine in which and are connected by a downflow return path 17.

(Embodiment) Explaining one embodiment of the present invention with reference to the drawings, a motor 2 is provided in a lower portion of a case 1, an upper feed spiral 3 is provided at a lower position of a vertical axis rotated by the motor 2, and the upper feed spiral 3 is provided. The rice milling roll 4 is attached to the upper part of the above, and the upper part of the reaching shaft is supported by the bearing 6 provided on the lower surface of the upper wall 5 of the base 1.

The outer circumference of the upper feed spiral 3 is surrounded by a shell tube 7, the outer circumference of the rice polishing roll 4 is surrounded by a perforated cylinder 8, a supply port 9 is formed in the lower part of the shell tube 7, and a supply hopper is provided outside the supply port 9. Install 10.

A discharge port 11 is formed at the upper end of the perforated cylinder 8 and a load resistance device 12 is provided outside the discharge port 11 so that the milled rice flowing out from the drain port 11 falls into a rice bag 14 below the milled rice removal trough 13. To form.

Further, reference numeral 15 is a switching valve, and when the switching valve 15 is switched, the switching valve 15 is taken out to the half-steamed rice return port 16 and returned to the supply hopper 10 located below the half-steamed rice return port 16 via the downflow return path 17. To do.

(Operation) Next, the operation will be described.

The motor 2 is energized, the upper feed helix 3 and the rice milling roll 4 are rotated, the load resistance device 12 is adjusted to a desired pressure, the switching valve 15 is switched to the state in which the half-steamed rice return port 16 is opened, and the supply hopper 10 is supplied. When brown rice is put in, the shell 9 from the supply port 9
It flows in, rises by the upper feed spiral 3, is milled by the milling roll 4, and the milled rice flows out from the outlet 11.

However, since the initial stage of smelting is a half-steamed state, it flows into the half-steamed rice return port 16 that is switched by the switching valve 15, flows down in the downflow-type return path 17 by its own weight, and is returned to the supply hopper 10. .

When the husks flowing out from the discharge port 11 are completely polished rice, the switching valve 15 is switched to close the half-rice polished rice return port 16 and the polished rice extraction trough 13 is opened to take out the rice into the rice bag 14.

(Effect) The one described in Japanese Patent Laid-Open No. 62-110752 relates to a downflow-type rice milling machine, and is a technique for returning the half-steamed rice discharged from the downflow-type rice milling machine to the original state for processing. However, it has a considerably complicated structure.

The one described in Japanese Patent Laid-Open No. 59-39349 is an ascending type rice milling machine, but a technique for returning the semi-polished rice to the original state is unsolved.

However, according to the present invention, the motor 2 is provided at the lower position in the case 1, the upper feed spiral 3 is provided below the vertical axis rotated by the motor 2, and the rice polishing roll 4 is attached above the spiral 3. The outer circumference of the upper feeding spiral 3 is surrounded by a shell shell 7, the outer circumference of the rice polishing roll 4 is surrounded by a perforated cylinder 8, and a supply port 9 is formed at a lower position of the shell shell 7 and a supply hopper is provided outside thereof. 10, a discharge port 11 is formed at an upper position of the perforated cylinder 8, and a load resistance device 12 is provided at the discharge port 11.
In the apparatus provided with, the polished rice removal gutter 13 and the half-rice return port 16 are formed outside the discharge port 11 through the switching valve 15, and the half-rice return port 16 is higher than the supply hopper 10. In the position, the half-polished rice returning port 16 and the supply hopper 10 are connected by a downflow return path 17 to form a half-polished rice returning device of a rising rice mill. Even though it is a return device, it can return semi-lost rice very easily, and a polished rice removal gutter 13 and a semi-loaf rice return port 16 are formed outside the discharge port 11 through a switching valve 15, The rice return port 16 is located higher than the supply hopper 10,
Since the half-steamed rice return port 16 and the supply hopper 10 are connected by the downflow-type return passage 17, they can be simply flowed back.
It is the cheapest structure and can return half rice.
