Description

[Detailed description of the invention] The present invention relates to an improvement of a vertical circulation rice mill.

Rice milling machines for home use in rural areas are divided into two types: large rice milling factories concentrated in cities and small milling machines distributed in villages facing artificial depopulation. It has become a custom to do so, and there is an urgent need to rationalize it.

Although rice producers should not regularly use poor-quality, low-grade rice that has been subjected to harsh urban living conditions, two types of rice milling methods have been used in the past, one of which is that brown rice is passed through the same milling room only once. The rice milling process is completed just by passing through the rice, and it becomes white rice.This method removes the bran almost completely, and although it is inferior to urban rice milling, there is no big difference in quality. In a rice milling machine (see Figure 7), a rice tank is placed on top of the milling chamber, and when rice is pushed up from the milling chamber into this tank and circulated,
Since the reaction of pushing up is used as resistance in the polishing chamber, a traditional fatal flaw is that it is impossible to avoid defects that result in extremely incomplete polishing. (see figure) is even more difficult to remove the rice bran because the polishing room does not have a polishing cylinder with a porous wall, and the rice grains that are once discharged from the upper discharge port cannot be removed by simply flowing down on the sloping screen. , the bran removal polishing is even more incomplete than the former horizontal type, and there are virtually no vertical type circulating rice mills in practical use.

The reason why we chose this circulation-type rice milling machine with poor polished rice quality is because
Even if the main parts of the whitening room are worn out and efficiency and other performance decreases,
The process is a circulation method, so if you leave it until it becomes white rice,
The ease with which rice can be made into white rice someday. In addition, since the rice milling process is minimal, there is no need to rush the rice milling process, and this model is evaluated on the premise that there are no constraints on the rice milling time, so it is a rather effective rice milling method under such special circumstances. However, the fact that the rice does not retain its sticky residue is a common and fatal flaw. Another drawback of horizontal circulating rice mills is that they tend to use a circulating method for polished rice because the rice circulates in a deformed tank. It is an object of the present invention to remove these defects and improve the rice so that it can self-sufficiently produce high-grade white rice that has been polished to remove bran.

Therefore, in the present invention, a polishing tube is placed concentrically in the center of a container or tank, and rice is supplied from the inlet around the bottom of the polishing tube near the low wall of the tank, and the rice is transported forward through the polishing chamber. By using a circulation process in which the rice is discharged uniformly around the entire circumference and circulated through the tank, it is possible to prevent the circulation method and process the rice into uniformly polished rice.Also, the bran generated in the milling room is removed through the perforated wall of the milling cylinder, and the rice bran is removed from the rice bran removal chamber. When the rice bran is removed from the tank through the falling path of the bran, it becomes beautiful polished white rice, and especially when it can be removed by the exhaust air suction of the air exhaust machine, it becomes even more vivid, ideal white rice that has not been washed.

In addition, the lower spiral sends the rice grains flowing in from the rice grain inlet to the milling cavity of the milling trochanter to generate the load necessary for milling, and the upper upward spiral eliminates the milling capacity as much as possible. Since it is the upper layer of the polishing tube, the density of rice grains is low, so the rice grains are lightly polished on the inner surface of the porous wall for removing rice bran, and the rice is discharged outside the polishing tube, so that the rice grains that have adhered to the rice grains are sufficiently removed. At the same time, it does not exert excessive overpressure on the whitening room.
Even if it suddenly stops during a power outage, there is no risk of clogging in the whitening room, and even if the machine is stopped at a graveyard, it will start without any trouble, and it has a rare buffering effect that allows it to start freely. This is also worth mentioning.

The reason why the conventional vertical circulation rice milling machine was not successfully put into practical use was because the rice bran removal was incomplete. In all of these methods, the milling cylinder inside the tank does not have a wall, and the rice grains are allowed to flow down a wire mesh surface tilted over the tank, but unless a special stirring structure is used, the rice grains are simply pressed against the mesh. All methods end in failure because the bran removal effect of the adhering bran on the surface of the rice grains cannot be removed by less than 1q when the rice grains are allowed to flow down.

In the present invention, the porous wall for removing rice bran is separated from the rice grain layer in the tank by the outer cylinder, and the stirring action and frictional force of the milling trochanter and the centrifugal force that the rice grains receive from the trochanter are used to move the porous wall into the rice grain removal chamber of the outer cylinder. High quality polished rice is processed by suctioning and removing the bran adhering to the surface of the rice grains, especially when the bran discharged into the outer cylinder is discharged from the vertical bran removal pipe through the blades by suction action. This method yields beautiful white rice that has been polished to remove the bran and has no white spots.

As described above, the present invention provides a vertical circulation rice milling machine with a bran-removal passage separated from the rice layer of the container on the outer periphery of the porous-walled rice bran-removal tube, thereby making it possible to mill beautiful white rice without adhering rice bran. It has been successful, and the effects are great.

In addition, for the whitening trochanter of the present invention, a grinding type made of a grinding wheel or a friction type made of iron is used.

The present invention will be explained with reference to embodiment figures. A friction-type polishing trochanter 2 is installed in the center of the rice grain input circulation container 1, which has a mouth-shaped cross section.

With the above-described configuration, when raw brown rice is supplied into the circulation container 1 and the device is started, the spiral rotor 3 and the milling rotor 2 are rotated by the vertical shaft 5, and the brown rice in the container is polished. The rice flows into the whitening chamber 9 from the rice feeding port 23 installed on the lower side of the cylinder 8 and undergoes a whitening action, and the rice bran generated by the whitening action is removed through the porous wall 7 and flows into the rice bran removal chamber 11. At the same time,
The drain 1 flows down the shelf fall path 14 from the drain port 12 at the bottom.
It is discharged from the exhaust IJi Ifi 22 to the outside of the machine via the i window 13. Also, the polished rice in the milling chamber 9 flows into the container 1 through the gap with the pressure lid 15, and the polished rice is circulated several times through the circulation process to be milled to a predetermined degree of polishing, and then sent to the next process.

Rice milling machine. 3. Detailed description of the invention The present invention relates to the improvement of a vertical circulation rice milling machine. The rice milling machine for home use in rural areas is based on the structure of rice milling in Japan, which is a combination of large rice milling factories concentrated in cities and small rice milling machines distributed in depopulated rural areas. Due to dualization, rice milling in rural areas has become a custom for each household to produce its own white rice, and there is an urgent need to rationalize it. Although rice should not always be milled, two types of rice milling methods have been used in the past, one of which is that brown rice passes through the same milling chamber once. With horizontal rice milling machine,
In this method C', bran removal is almost sufficient, and urban rice milling J.
(Although there is no significant difference in quality, the other 1
Seeds are purchased in a horizontal circulating rice mill (see Figure 7), where a rice tank is added to one portion of the milling yen, and the rice is pushed up from the milling room into this tank (
J (During circulation, the reaction of the push-up is used as resistance in the polishing chamber, so the defect that makes the polishing process very incomplete) is unavoidable in the traditional This is a fatal flaw, and the vertical circulating rice mill (see Figure 8) does not have a porous wall (111) in the milling chamber (--it is difficult to remove the rice bran from the top 1 exit). Because the discharged rice grains flow up on the sloping mesh and the adhering bran of CI and L rice grains cannot be removed, the former method (removal polishing is even more incomplete than the hanging type), and in fact, it has not been put into practical use. (There are no vertical circulating rice mills available.) The reason for choosing this circulating rice mill, which has poor polished rice quality, is
Although the main parts of the whitening room were worn out and the efficiency decreased,
The process is a circular 1 type (leave it until it becomes white rice)
The advantage lies in the ease with which rice can be made into white rice someday. In addition, it is a model that is evaluated on the premise that there is no restriction on rice polishing time because it does not rush or rush the rice polishing process (C, which only produces 4g of rice). There is a type C. However, it is a common defect in V-kidokoro ('J C5 polished rice with no bran is destined to be removed).In addition, in horizontal circulation rice mills, rice is circulated in a deformed tank. Therefore, the In orientation, which causes circulation spots in polished rice, is also a defect.The invention of the present invention removes these defects and improves the ability to self-sufficient C-polished Chang grade white rice using a household circulation rice mill. Therefore, in the present invention, a milling cylinder is installed concentrically in the center of a container or a straw tank, and the charging cylinder around the bottom of the tank near the bottom wall facing the milling is used to collect rice. It is possible to prevent uneven circulation and process uniformly 18% white rice by supplying rice, sending it down the milling room, discharging it uniformly around the entire circumference, and circulating it evenly through the ζ tank. The resulting bran is removed through the porous wall facing the polishing, and the path of the bran from the bran removal chamber is expelled to the outside of the llC tank.
The exhaust air from the exhaust vane is sucked into the air by the air exhaust vane. is placed at the bottom of the milling λ of the milling trochanter (b (which generates the load necessary for milling), but there is a part of it that eliminates the upward feeding spiral milling ability as much as possible. At the same time, the density of the rice grains is thinner because it is the soil layer of the polishing tube.The inner surface of the porous bowl for removing the rice grains for polishing (lightly polishing to remove the bran and ejecting the grain from the polishing tube). It removes rice bran and whitens it.1. It doesn't cause any harmful effects, and it stops suddenly in the event of a power outage.1^ White!There is no danger of clogging, and it starts smoothly and smoothly when stopping suddenly. It is also worth mentioning that it has an easy start-up and is equipped with the rare M-type rice control system that allows it to start freely.The conventional vertical circulation M-rice mill was not successfully put into practical use. It was,
There was something wrong with removing rice bran. , None of these had a suppression wall in the direction of the milling inside the tank, and the flow was like a floating stream on the wire mesh surface that was tilted in the tank. R: ``There is, but the rice grains are simply pressed against the net or floated on the net unless there is a special agitation method. Removal of sticky adhering bran (1) No effect can be obtained or (C1) are all failures.The present invention is based on a method in which a porous wall for removing bran is separated from the rice grain layer in the tank by an outer cylinder. , due to the stirring action of the milling trochanter, ■ψ frictional force, and the mental force of the rice grains being pulled from the trochanter (the bran is sucked out from the porous wall into the bran removal chamber facing outward, and the adhering bran on the surface of the rice grains is thoroughly removed). High-quality polished rice is processed by removing and wiping the rice, and in particular, the bran discharged outward is passed through the rice bran by suction (passing through the rice bran from the vertical bran removal pipe). Thus, the present invention provides a vertical circulation rice polishing machine with a separation chamber and a removal passage separated from the rice layer of the container on the outer periphery of the polishing tube with the porous wall 117. [We succeeded in milling beautiful grained white rice with no adhering bran, so the effect is great.

When the grain trochanter 3 and the milling trochanter 2 are rotated by the vertical shaft 5, the brown rice in the container is placed under the polishing tube 8. The rice grains flow into the whitening chamber 9, where the pressure of their own weight decreases as they move upward from the rice feed opening 23, where they undergo a whitening action (the resulting bran powder is absorbed by the porous walls). -7 and flows into the bran removal chamber 11 (C), and flows down from the bran discharge port 12 at the lower part through the bran discharge port 14 through the bran discharge window 13 and from the bran discharge tiii 22.
