DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice mill used mainly at home.

[0002]

2. Description of the Related Art In recent years, with the desire for gourmet food and healthy food, there has been an increasing demand for brown rice to be polished to a desired degree at home, cooked freshly cooked rice, and eaten.

Conventionally, this kind of rice mill has been disclosed in Japanese Patent Laid-Open No. 4-274.
The configuration is as shown in Japanese Patent Publication No. 44-44, and will be described with reference to FIG.

[0004] As shown in the figure, a rice polisher 1 comprises a box-shaped container frame 2.
The rice bran refining cylinder 3 is laid horizontally inside the inside, and the rotating horizontal axis 4 is
And the rotating horizontal shaft 4 is supported by the bearing 5.
The rotating horizontal shaft 4 is provided with a milling trochanter 6 and a spiral trochanter 7 each of which is a friction-type roll, and the outer periphery thereof is formed in a milling chamber 8. A rice discharge port 11 provided with a milling degree adjusting device 10 is provided on the rice discharge side.

In the above configuration, when the brown rice supplied from the supply port 9 falls into the polishing chamber 8 and is milled by the rotation of the milling trochanter 6, the milling degree adjusting device 10 at the rice discharging port 11 appropriately adjusts the brown rice. After the milling pressure is applied and a predetermined degree of milling is attained, the rice is dropped from the rice discharge port 11 and discharged to the outside 1 of the rice mill.

[0006]

However, in such a conventional rice mill, in order to obtain a high degree of whiteness, a resistance lid 1 is required.
Although the flow of the milled rice in the milling chamber was restricted by 1 to increase the so-called milling pressure, the higher the degree of milling, the greater the pressure received by the shell grains, which forced an increase in crushed grains. Until now, attempts have been made to improve the shape and the like of the milling trochanter 6, but it is still not a thing that can prevent the occurrence of crushed granules, and the crushing increases the resistance in the milling chamber 8, and eventually the trochanter 6 is locked and rotated. Will stop. If the milling trochanter 6 locks, the rice bran milling cylinder 3 is removed to remove the crushed granules. However, it is difficult to remove the rice grains biting around the rice feed port 9 side, and the rice grains hinder the state where the rice grains remain. However, there is a problem that it is difficult to attach a rice bran refining cylinder.

An object of the present invention is to solve the above-mentioned problems, and an object of the present invention is to make it easier to attach and detach a rice bran removing tube when locked.

[0008]

SUMMARY OF THE INVENTION In order to attain the above object, the present invention provides a bearing in which a rice bran polishing tube is detachably mounted horizontally inside a box-shaped container frame, and a rotating horizontal shaft is inserted therein.

[0009]

According to the above means, when the rice bran removing tube is inserted into the holding portion, the inclined rice communicating with the rice bran container is provided below the rice bran removing tube in order to prevent the rice bran from biting between the rice removing rice polishing tube and the holding portion. Is provided , and the surrounding space is widened, so that the attachment and detachment of the rice bran refining cylinder becomes easy.

[0010]

An embodiment of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1 to FIG. 3, the rice mill 21 has a rice bran polishing tube 23 removably mounted horizontally inside a box-shaped container frame 22.
The rotating horizontal shaft 24 is inserted into the inside thereof, and the rotating horizontal shaft 24 is supported by a bearing 25. The rotating abscissa 24 is provided with a polishing roller 26 and a spiral roller 27, which are friction-type rolls, respectively, and the outer periphery thereof is formed in a polishing chamber 28.
The rice supply port 29 is provided on the rice supply side, and the rice discharge port 31 provided with the milling degree adjusting device 30 is provided on the rice discharge side. The rice feed port 29 is provided with a hopper 32 for storing shell grains before milling, and a bran container 33 below the milling cylinder 23. Body 2
A discharge port 31a for discharging polished rice to the outside of the main body 21 is provided at a lower front portion of the main body 1. A sensor 34 is provided. Motor 35 as drive unit
Transmits the rotational force to the rotating horizontal shaft 24 by the belt 36,
The operation is controlled by the control means 37. The operation switch 38 sends signals to the control means 37 for starting and stopping rice polishing.

The fineness adjusting device 30 adjusts the urging force of a resistance lid 40 provided on the rice discharging side of the whitening chamber 28 by a pressure adjusting spring 39 so as to be freely pressurized by an adjusting knob 41 to obtain a predetermined polishing pressure. It is. The rice bran removing cylinder 23 has a side surface held by the holding portion 22a of the box-shaped container frame 22 on the rice feeding side, and a lower portion 22b has an inclined portion communicating with the rice bran container 33. Further, on the rice discharging side, a holding portion 42a is fitted to the outer periphery of the rice bran refining cylinder 23, and is held by a holding plate 42 detachably fixed to the box-shaped container frame 22 with screws 43.

Next, the operation of the rice mill configured as described above will be described. When the operation switch 38 is pressed, the motor 35 is driven, the torque is transmitted by the belt 36, and the rotating horizontal shaft 24 rotates. Then, the brown rice stored in the hopper 32 flows down from the rice feed port 29 to the polishing room 28. The unpolished rice is first fed into the spiral trochanter 27, transported by the spiral groove 27a, taken over by the milling trochanter 26, flows down from the rice discharge port 31, and flows from the discharge port 31a to the rice mill 2
It is discharged outside 1. At the rice discharge port 31, the pressure adjusting spring 3
In 9 the so-called milling pressure is increased by restricting the flow of the milled rice in the milling chamber 28 by the resistance lid 40 urged to the rice discharging port side, and the milled rice is rubbed with each other in the milling chamber 28 to mill. Is done. The rice bran rubbed off since the slit 23a is inserted in the rice bran refining cylinder 23 is dropped into the rice bran container 33 from the slit 23a and stored. By the way, when the brown rice disappears in the hopper 32, the discharge of the refined rice from the rice discharge port 31 naturally also stops, and the rice passing through the facing optical sensor 34 disappears, so that the absence of the rice is detected. , Motor 3 after a certain time from detection of rice absence
Stop 5.

In addition, the milling pressure in the milling chamber 28 may be more than necessary due to the brand of brown rice, brown rice having a high moisture content, etc.
That is, since the milling is performed with over-whitening, the pressure applied to the husk grains increases and the amount of broken rice increases, eventually the resistance in the whitening chamber 28 increases, and finally the rotating horizontal shaft 24 locks and stops rotating. become. In this case, the user is
Because brown rice remains, it can be determined that the stop is due to the lock. Now, when locked, the broken rice in the rice bran refining cylinder 23 must be removed. This analytical cleaning is performed by removing the screw 43 of the holding plate 42 and pulling out the bran removing tube 23 toward the user. At this time, the rice bran refining cylinder 23 and the rotating horizontal shaft 24 can be easily cleaned, but the periphery of the rice feeding section 29 is narrow and difficult to clean because it is located at the back, but the lower part 22b of the holding part 22a holding the rice bran refining cylinder 23 Is inclined to the bran container 33, so that rice and bran deposited on this portion fall into the bran container 33 and are collected. Therefore, when attaching the rice bran refining cylinder 23, the rice bran refining cylinder 23 is inserted into the holding portion 22a from the front, but rice bran does not bite between the rice bran refining cylinder 23 and the holding portion 22a and cannot be inserted. . Rice outlet 31
Is a holding portion 4 of a presser plate that fits with the outer periphery of the rice bran refining cylinder 23.
