BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a milling apparatus, and more particularly, to a milling apparatus for injecting compressed air into a portion where milling is to be carried out to facilitate removal of the layer.

In general, the processing of rice into rice is called milling, and rice is composed of rice hull layer> rice bran layer (米糠 層)> snow (배)> endosperm (현). In addition to endosperm, rice bran (米糠) consisting of skin, seed skin, and whistle layer was removed.

The white rice we consume is obtained from the process of raw rice → Jeongseon → Jeonseang → Separation of rice → Separation → Rice milling → Steelmaking → Tailings → Sorting → Weighing, Packing → Product.

However, through this process, many important nutrients contained in rice are destroyed. One of them is rice snow, which contains more than 66% of nutrients in rice, which is essential for the human body called “GABA (Gamma Amino Butyric Acid)”. Nutritional ingredients are included only in rice eyes.

In addition, rice contains 6 times as much phytic acid as detoxifying heavy metals than white rice, and contains fiber and vitamins in addition to rich protein, fat, and carbohydrates, and 40 to 60 times stronger in antioxidant activity than tocopherols. It contains tocotrienol, which is found to be active, and 'orizanol,' which prevents stroke and dementia by activating the activity of brain cells. It is also known to be effective in prevention.

In addition, brown rice, which has been removed only by chaff, has high quality vegetable protein and other minerals such as fat, calcium, phosphorus, sodium, iron, vitamins A, B1, B2, B6, E, folic acid, pantothenic acid, nicotinic acid, and folic acid. It is contained.

In other words, to eat rice after the process of milling is to eat white rice containing a large amount of sugar and all the major nutrients are gone.

Therefore, in recent years, rather than eating white rice, which is processed and sold in large quantities, modern people are moving toward the trend of ingesting rice containing natural nutrients directly at home according to taste.

In line with this trend, many rice milling devices have been widely used in homes. Generally, a milling device for processing a small amount of rice or brown rice (hereinafter referred to as rice) is a friction type milling device. Adjacent to the screw is a rotary blade formed on the outer surface with a straight line or a fixed angle is composed of the main shaft and the other supply chain.

In the above-mentioned cutting device, the rice grains are supplied to the conveying screw and transported along the conveying screw and the conveying blade to the outlet side of the cutting apparatus, and the surface is peeled off by friction with neighboring rice grains or other supply networks. It is discharged to the outside through the through-hole formed in, the peeled rice grains are discharged through the outlet formed in the minute control.

As described above, when rice is peeled off by friction with other rice or other supply chains, rice or bran may sometimes get stuck in the perforated holes of the other supply network. Existing milling devices forcibly discharge such embedded rice or other layers. There was no means to reduce the performance of the pot.

For this reason, a separate blower, a device that generates a separate wind, is separately installed to blow air around the other supply network to blow or suck chaff or bran to separate it from the rice. In this case, the blower is installed to be driven by a separate power. The problem is that the device is bulky.

In addition, since the blower only blows the wind of low pressure, the fine grains firmly stuck in the perforation holes cannot be forcibly discharged, and thus the yield of the rice polisher cannot be greatly improved.

In addition, when the rice is milled, a large amount of rice bran is generated. If the rice bran is attached to rice, the low-pressure wind alone makes it difficult to separate the rice from rice, and the rice is separated from rice and is not forced out of the mill. It accumulates in other supply chains and degrades the cutting performance.

In addition, it prevents the cooling of heat generated by friction due to accumulation on the rotating shaft and other supply networks during the cutting.

In addition, there is a risk that corrosion may occur or insects may remain inside the main body of the cutting apparatus such as the rotating shaft and the other supply chain even after the cutting is finished.

Accordingly, the present invention has been made to solve the above problems, the object of the present invention is to forcibly discharge high-pressure compressed air into the potting device to facilitate the discharge of rice or bran through the other supply network, It is therefore an object of the present invention to provide a milling apparatus capable of improving the milling efficiency.

For this purpose, the milling apparatus according to the present invention is provided in the housing and the housing, a plurality of perforation holes for discharging the grain bark on the outer circumferential surface, the rice grain outlet for discharging the rice grains at one end Another supply network formed, rotatably installed in the housing, a rotary blade for rotating the rice grains supplied to the inside of the other supply network on the outer peripheral surface, a plurality of injection holes for injecting compressed air supplied from the outside to the other supply network and And a rotating shaft having a hollow portion for transferring compressed air to the injection hole, a driving portion for rotating the rotating shaft, and generating compressed air in association with a rotating motion of the rotating shaft, and transferring the generated compressed air into the hollow portion of the rotating shaft. Characterized in that it comprises a compressed air generating unit.

Hereinafter, with reference to the accompanying drawings and preferred embodiments will be described in detail the present invention. For reference, detailed descriptions of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted in the following description.

First, Figure 1 is a cross-sectional view showing a configuration according to an embodiment of the present invention the present invention.

According to an aspect of the present invention, a cutting apparatus includes a housing for supporting respective components, a rotation shaft 110 which penetrates the inside of the housing in a longitudinal direction and is rotatably supported by bearings installed on both sidewalls of the housing, and A motor 500 that is connected to a rear end of the rotary shaft 110 and rotates the rotary shaft 110, and a reciprocating compressor 200 that is installed at the rear end of the housing and generates compressed air in cooperation with the rotary shaft 110; , A hopper 120 installed in the housing stop and dropping the introduced rice into the transfer screw installed on the outer circumferential surface of the rotating shaft 110, and another supply network 118 surrounding the front end of the rotating shaft 110 inside the housing front end. It consists of a metropolitan government (100) including.

As shown in FIGS. 1 and 2, the rotating shaft 110 has a hollow portion 160 formed therein, and the compressed air is formed on the outer surface of the rear portion connected to the compressed air generating unit 200. Compressed air inlet 162 is formed to be introduced into the unit 160.

In addition, a plurality of injection holes 116 are formed in front of the rotating shaft 110, that is, precisely speaking, a portion corresponding to the other supply network 118 to inject the compressed air supplied through the hollow part 160 in the radial direction. .

Referring again to other components with reference to Figure 1, the motor 500 is installed in parallel with the rotating shaft 110 in the lower outer side of the housing.

The motor 500 and the rotation shaft 110 are connected by pulleys 150 and 510 coupled to respective shafts and a belt 520 connecting the pulleys 150 and 510.

The cam 400 is eccentrically installed on the rotation shaft 110.

The eccentric rotation of the cam 400 transfers power to the piston 210 of the reciprocating compressor 200 by a connecting rod 240 connecting the cam 400 and the piston 210.

Referring to FIGS. 3 and 4, the motion conversion according to the connection structure of the cam 400 and the connection rod 520 is described in detail. The accommodation portion of the connection rod 240 may accommodate the cam 400. A portion 242 is formed and the upper end is coupled to the piston 210.

The accommodating part 242 has a ring-shaped groove 244 formed on the inner surface of both sides of the circumferential surface and the rim of the cam 400 so as to be fixed therein, and the cam 400 is the groove 244. It is pulled in and fixed.

In addition, the accommodation part 242 is separated into both sides of the first accommodation part 240B and the second accommodation part 240A so that the cam 400 can be fitted into the groove 244 of the accommodation part 242. Has a structure.

That is, the semi-circular first accommodating part 240B is separated from the cam 400 by being inserted into the recess 244 of the second accommodating part 240A. After engaging the cam 400 and the second accommodating portion (240A) and fastening the bolts to the top and bottom fixed.

Therefore, the receiving portion 242 is completely wrapped around the circumferential surface of the cam 400, the rotational movement of the cam 400 is all transmitted to the piston 210 so that the piston 210 is elliptical Up and down reciprocating motion.

As a result, vibration generated when the piston 210 collides with the inner wall of the cylinder 260 may be transmitted to the cam 400 so that the cam 400 may be separated from the receiving portion 242. As described above, since the cam 400 is completely fixed to the recess 244 of the accommodating part 242, the cam 400 may be prevented from being separated from the accommodating part 242.

As described above, since the reciprocating compressor 200 is interlocked with the rotary shaft 110 to generate compressed air, a separate power device for driving the reciprocating compressor 200 is not required. It is configured to reduce the volume of the milling device to a minimum.

Next, a structure and an operation of the compressed air generator 200 will be described with reference to FIGS. 5 to 9.

The piston 210 coupled to the upper end of the connecting rod 240 is separated into an upper piston 212 and a lower piston 218.

The upper piston 212 and the lower piston 218 and the connecting rod 240 coupled to the lower piston 218 are coupled to each other by bolts.

The upper piston 212 seals the inside of the cylinder 260 and serves to form a compression chamber.

The circumferential portion of the upper piston 212 guides the reciprocating motion of the piston 210 and is a self-lubricating material capable of absorbing vibration that may occur when the piston 210 hits the inner wall of the cylinder 260, For example, a teflon rider ring 214 is attached.

In the present embodiment, the connecting rod 240 swings up, down, and laterally by the eccentric rotation of the cam 400. When the length of the connecting rod 240 is not long, the displacement in the side is not large. Since the connection rod 240 is not rotatably connected to the piston 210, the vibration due to the lateral displacement may be sufficiently attenuated only by the elastic force of the rider ring 214.

In addition, the rider ring 214 of the Teflon material is a self-lubricating material, so the reciprocating compressor 200 does not require a separate lubricant.

And by attaching the rider ring 214 of the Teflon material can minimize the noise that can occur in the reciprocating compressor 200 can be used without difficulty in the home.

The valve plate 220 and the cylinder head 230 for controlling the inflow or outflow of air into the cylinder 260 as shown in FIGS. 6 and 7 are stacked on the upper end of the cylinder 260.

Referring to FIG. 6, the valve plate 220 is installed at the upper end of the cylinder 260 to form an upper surface of the inner compression chamber of the cylinder 260 to form the compression chamber. It serves to seal the outside.

The valve plate 220 is formed with an inlet 228 and an outlet 224 penetrating the valve plate to allow air to enter and exit.

In addition, one end of the valve plate 220 is fixed to the inner side by a bolt and the other end of the valve plate 220 having a predetermined elastic force covering the inlet 228 and the valve plate 220. At the outer side, one end is fixed to the outer side by a bolt and the other end is provided with a discharge valve plate 222 having a predetermined elastic force covering the outlet 224.

On the upper end of the valve plate 220 and the outside air inlet chamber 237 and the inner side so that the outside air introduced into the cylinder 260 and the compressed air discharged from the cylinder 260 as shown in FIG. The cylinder head 230 formed by separating the compressed air discharge chamber 238 from each other is installed.

The external air suction chamber 237 is formed with an external air suction port 232 connected to the outside through the cylinder head 230 so as to suck the external air therein, and the foreign air is sucked into the external air suction chamber 237. The air purification filter 236 may be installed so as not to be suctioned.

The compressed air discharge chamber 238 is provided with a compressed air discharge port 234 connecting the compressed air discharge chamber 238 and the compressed air flow path 300 formed in the housing.

The compressed air discharge chamber 238 repeats the operation of opening and closing the compressed air discharge valve plate 222 up and down in the compressed air discharge chamber 238 to the operation of the compressed air discharge valve plate 222. It should be manufactured in a size that does not affect.

Hereinafter, a process of generating compressed air in the reciprocating compressor configured as described above will be described in detail with reference to FIGS. 8 and 9.

The pressure in the compression chamber is changed according to the reciprocating motion of the piston 210. As shown in FIG. 8, when the piston 210 is lowered from the top dead center to the bottom dead center, the air pressure inside the compression chamber is lower than the outside. Since the suction valve plate 226 is opened, the outside air is introduced into the cylinder 260 through the outside air inlet 232.

As shown in FIG. 9, when the piston 210 rises from the bottom dead center to the top dead center, the air pressure in the compression chamber is increased, and the discharge valve plate 222 is opened by the raised air pressure. Compressed air is discharged from the cylinder 260 to the outside.

Compressed air generated as described above is formed in the housing to the hollow portion 160 in the rotating shaft 110 by the compressed air flow path 300 connecting the compressed air outlet 234 and the rotating shaft 110. Transferred.

The reciprocating compressor 200 continuously generates compressed air while repeating such an operation.

Hereinafter, the overall operation of the above-mentioned milling device will be described.

First, when power is applied and driven to the motor 500, power is transmitted to the rotation shaft pulley 150 through the motor pulley 510 and the belt 520.

As the rotary shaft 110 rotates, the transfer screw 112 installed on the rotary shaft 110 also rotates and transfers the fine grain falling onto the transfer screw 112 into the other supply network 118.

The rice grains transferred into the other supply network 118 are forcibly rotated in the other supply network 118 in the rotation direction by the rotary blades 114 installed on the rotation shaft 110.

In addition, since the rice grains falling from the hopper 120 are continuously conveyed by the transfer screw 112 and pushed into the other supply network 118, the rice grains are pressed and compressed in the other supply network 118. .

Therefore, the rice is rubbed by the rice or other supply network 118 while being in close contact with the other supply network 118, compressed and rotated.

The piston 210 of the reciprocating compressor 200 connected to the rotary shaft 110 performs reciprocating linear motion and generates compressed air while the rice and rice are inverted.

The compressed air generated as described above passes through the compressed air discharge chamber 238 and the compressed air flow path 300 of the cylinder head 230 to the compressed air inlet of the rotary shaft.

The rotary shaft 110 is rotated by the motor 500 so that the compressed air flow path 300 and the compressed air inlet are not always in contact with each other, but the compressed air flow path 300 and the compressed air inlet 162 are Since the connected part is sealed with the outside, the compressed air is naturally introduced into the hollow portion 160 of the rotating shaft 110 having a low pressure through the compressed air inlet 162.

As such, the compressed air transferred into the hollow portion 160 of the rotating shaft 110 is formed on the outer surface of the rotating shaft 110 passing through the other supply network 118 and communicated with the hollow portion 160. It is injected into the other supply network 118 through the air injection port 116.

The position and the number of the compressed air injection holes 116 are formed can be provided by the user arbitrarily selected.

As described above, the compressed air continuously injected into the other supply network 118 is forcibly separated from the milled rice and the bran layer and discharged out of the other supply network 118.

In addition, even if the rice is firmly lodged in the perforated hole 119 of the other supply network 118, compressed air is continuously injected into the other supply network 118 as described above, so that the finely embedded rice is firmly embedded in the other supply network ( It has the effect of further raising the pressure in the 118, and eventually is discharged out of the supply chain 118 without overcoming the pressure.

And compressed air is supplied between the rice grains to be milled and discharged out of the other supply network 118 so that the rice bran generated as the rice grains are not stuck to the rice grains or other supply network 118.

In addition, when the rice grains are frictionally coated as described above, the quality of the rice grains may be affected by the heat generated from the rice grains or the rotating shaft 110 and the other supply network 118, which is supplied between the rice grains as described above. Compressed air cools the heat that can be generated as described above to prevent deterioration of rice grain quality.

In addition, the compressed air generated as described above is operated using the milling apparatus in a state where the other supply network 118 into which the rice is not input is empty, and the remaining air remaining in the milling apparatus is removed using the compressed air. Problems that may occur due to discharge, such as bees can be solved without disassembling the cleaning device.

When the rice and bran is separated, the rice is controlled by the minute adjuster 140, the degree of falling down to the pedestal 130 and the chaff is discharged to the outlet.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art to which the present invention pertains can implement the present invention in other specific forms without changing the technical spirit or essential features, The embodiments are to be understood in all respects as illustrative and not restrictive.

For example, the connecting rod may combine the first connecting rod and the second connecting rod having a first connecting rod coupled to the bottom surface of the piston and a receiving portion surrounding the outer surface of the cam. It may be configured to include a coupling means.

Therefore, the scope of the present invention is defined by the appended claims rather than the foregoing description, and all changes or modifications derived from the meaning and scope of the claims and their equivalent concepts are included in the scope of the present invention. Should be interpreted.

As described above, the milling apparatus according to the present invention is the milling yield of the milling apparatus by the by-products generated when the rice or bran gets stuck in the other supply network or the milling by spraying compressed air into the other supply network inside the It prevents deterioration.

In addition, by configuring the compressed air generating unit integrally with the milling device, a separate power unit and power are not required, and the volume of the milling device can be reduced to a minimum.

In addition, by using the compressed air to remove the residue remaining in the interior of the pot can be eliminated the need to disassemble and clean.
