(Points of interest)
Currently, the performance required of commercial rice mills that are widely used is low-temperature rice milling, which suppresses the deterioration of taste, produces less crushed grains, has good chopping quality, and gives the rice a glossy finish with high yield. In addition, there are various points such as quietness, excellent rice milling speed, high durability and maintainability, and high economics. In recent years, there has been a growing interest in food safety and a strong demand for accurate quality labeling. In the rice grain sales industry, which is trying to accurately respond to the increasingly complex market needs, such as a variety of brand rice varieties, quick and low-priced shipping through small-scale rice processing, If different milled rice remains in the milling machine, even if a small amount is mixed in the milled rice in the next process, rice that is different from the original taste may be shipped and the consumer's confidence may be lost. It is absolutely necessary to prevent contamination It has become a must.

    However, the conventional rice milling machine cannot completely discharge the remaining rice in the milling chamber that always remains after the milling process by normal operation. If the disassembly is performed using maintenance tools and the milling chamber is opened once and then cleaned, there is a major disadvantage that the remaining rice cannot be removed sufficiently. The current situation is that the process of removing residual rice has to be repeated every time, depending on the change of the milled rice varieties and each milled lot.

(Conventional technology)
Among them, a shutter provided on the hopper of the charging unit, and a milling roll, such as the one proposed in Japanese Patent Application Laid-Open No. 2004-358428 “Rice milling machine” as a measure to overcome this, Connect the blowout port of the supply port air passage extended from the blower dedicated to the supply port between the supply port of the milling section that performs whitening processing by the air blower, and perform the air blowing operation to the air supply port air passage in conjunction with the closing operation of the shutter In a blower that blows air into the rice milling mechanism, such as those capable of blowing air from the milling section supply port toward the discharge port, or the “rice milling apparatus and rice milling method” disclosed in Japanese Patent Application Laid-Open No. 2004-337805. In addition, a cleaning blower that can ventilate the brown rice supply path connected to the rice milling mechanism is installed, and the outside of the rice milling outlet is made negative by the suction force of the transfer machine that communicates with the rice milling outlet in a substantially sealed manner. A separate section is formed and the rice in the rice milling mechanism can be discharged and exhausted together with the exhaust, or, as in the “rice milling machine” invention described in Japanese Patent No. 3618293, it is arranged below the screen of the whitening mechanism. A suction fan that generates a suction force in the suction chamber, and a blast-type removing device that includes a blast pipe branched from the exhaust pipe, and a whitening mechanism and a brown rice reservoir on the discharge end side of the blast pipe Some are connected to a shutter for opening and closing the tank dropping port, and some are capable of using a suction fan for removing the soot for removing residual rice.

However, in the former “rice milling machine” invention, a supply port blower dedicated to residual rice removal is added in addition to the removal blower provided for sucking and removing the soot discharged from the milling chamber. In addition, the following “rice milling apparatus and rice milling method” invention also includes a blower for discharging rice bran from the milling chamber, and a separation section formed outside the rice mill discharge port, outside the blower for cleaning, A first rice milling machine exhausting means connected to the rice hopper so as to make negative pressure possible, and a second exhausting means that is provided in a transfer machine separate from the rice milling machine and can make the separation section negative pressure Both of these have the disadvantages that a new blower for removing residual rice has to be newly added, leading to an increase in the size, complexity of the rice milling machine, and price increase. The latter "rice milling machine" invention is By connecting the exhaust pipe of the suction fan provided for sucking rice cake from the white room to the brown rice entrance space, it is possible to avoid the incorporation of a new blower for removing residual rice, making the rice mill larger and more complicated. However, even during the removal of residual rice, the action of sucking rice cake from the milling chamber works, and the residual rice is adsorbed by the milling chamber and scouring net, so that smooth residual rice removal is possible. It left the fault that an effect | action was not acquired.

(Awareness of problems)
As mentioned above, all of the previously proposed “rice milling machines” and “rice milling equipment and methods” require an additional blower dedicated to removing residual rice, increasing the size and complexity of the rice milling machine. The latter "rice milling machine" supplies exhaust air from the suction fan provided to suck rice cake from the milling room to the brown rice entrance space of the milling room. However, because of the structural reasons, it is possible to discharge residual rice without adding a new blower. Also, during the process of removing residual rice, the suction force from the same suction fan works on the debris net in the same milling chamber, causing the residual rice to be adsorbed to the demineralization net along with straw and broken rice And the disadvantage of hindering efficient discharge of residual rice And are, to completely remove the residual rice from polished room, a refined mechanism decomposition, to check if still necessary, it was those leaving the problem that must be cleaned.

(Object of invention)
Therefore, the present invention eliminates all the phenomena that can hinder residual rice removal, such as adsorption of residual rice by a suction fan for sucking and discharging rice cake, without adding a blower for discharging residual rice. From the judgment that it is not possible to develop a new residual rice discharge technology that can quickly and completely remove residual rice, we started its development and research very quickly, and took a long trial and error, and many trials and experiments.

It is.

    If these structures are shown as a more concrete one, a predetermined range in which a milling room having a supply port of a brown rice hopper and an opening / closing shutter thereof is installed in the upper part of one end side, and closer to the rice milling outlet of the milling room In addition, a whitening roll having a cylindrical net removal net and a spiral groove portion for supplying brown rice under the supply port was loosely inserted so as to be driven to rotate by a rotational drive source arranged outside the milling chamber.

The suction switching chamber has a trap suction port and an outside air suction. Open and close the mouth selectively and alternately While the suction switching valve is provided, an exhaust air outlet and an outside air outlet are formed in the suction device air outlet, and the exhaust air outlet and the outside air air outlet can be selectively opened and closed alternately.

Any one of the above, provided with a switching shaft that is instantaneously linked and operable to switch, a suction switching arm connected to the suction switching valve, and a discharge operation mechanism connected to the ventilation switching valve. It can be said that it is a rice mill using the residual rice discharging apparatus described in the above.

    As described above, according to the residual rice discharging apparatus for a rice milling machine of the present invention, the residual rice in the milling room can be effectively removed by using the suction device provided for the rice bran collection unit attached to the whitening mechanism. In particular, a suction switching chamber having a suction switching valve is provided at the suction port of the suction device, and a ventilation switching chamber having a ventilation switching valve is provided at the ventilation port. When receiving a discharge start operation, the suction switching chamber 糠 suction port is closed and the suction switching valve is switched so as to open the outside air suction port. Operates to switch the air supply switching valve to open the mouth, allowing the outside air to be taken into the suction device that was used for soot suction, the outside air taken into the suction device through the outside air outlet, It is possible to inject at the key points When receiving a discharge stop operation, the suction switching chamber 糠 suction port is opened and the suction switching valve is switched to close the outside air suction port. Residual rice is discharged by switching the blower switching valve so as to close the mouth, making the suction power of the suction device for soot collection, and making it possible to operate and operate instantaneously so that the exhaust can be released to the outside In this case, no suction force is generated on the side of the slag collection unit, and the residual rice that is jetted into the semen chamber from the suction device and blown off to the supplied outside air is smoothly removed, and the discharge operation mechanism Immediately after the outside air is blown vigorously at the key points of the milling mechanism by repeatedly switching and operating multiple times, the outside air blowing is stopped and suction is taken from the soot recovery unit. Force It is possible to remove it simply and completely, by repeating it repeatedly over several times, applying a shocking shaking to the residual rice adhering to the wall surface etc. Compared to the type that required the disassembly and cleaning of the whitening mechanism for the complete removal of residual rice, such as the types of rice milling machines and rice milling equipment and methods, the efficiency of residual rice removal work is markedly higher. It is possible to achieve an excellent effect of greatly improving the processing capacity of rice milling.

    Furthermore, the residual rice discharge device for the rice mill is combined with a whitening mechanism provided with a cylindrical type debris net in the rice milling chamber and a rotary type whitening roll that is loosely inserted thereinto, and the outside air blowing port of the air blowing switching chamber By connecting the end of the outside air blast pipe line connected to the white rice roll spiral groove below the brown rice supply port, the mesh-like outside air spout opened so as to face in the general tangential direction, discharge When the residual rice discharge operation part of the operation mechanism receives a start operation of residual rice discharge, outside air is supplied in a jet form along the spiral groove groove of the whitening roll, realizing a smoother discharge of residual rice It is possible to obtain an excellent feature that it can be applied.

    According to the rice mill using the residual rice discharging apparatus of the present invention, the suction switching valve of the suction switching chamber and the ventilation switching valve of the ventilation switching chamber are linked to each other and synchronized with each other by an operation input via the discharging operation mechanism. Since the operation is completely different from the opening / closing operation of the open / close shutter provided at the brown rice supply port, the residual rice is discharged by the rice cake recovery unit. It is discharged smoothly without receiving the suction force, and by closing the open / close shutter and removing the remaining rice, new brown rice and glutinous rice are inadvertently discharged from the brown rice supply port during the discharge of the remaining rice. In the mesh-like outside air spout that can be surely prevented from being supplied, and that one end of the outside air blowing duct is opened so as to face toward the tangential direction of the milling roll below the brown rice supply port. To be connected Therefore, even during the milling process, brown rice, milled rice, etc. supplied into the milling room can be blocked by the mesh-like outside air outlet, and the backflow to the suction device can be reliably prevented, and the residual rice can be discharged. During processing, the outside air jetted from the mesh-like outside air outlet into the milling chamber flows along the milling roll spiral groove and is directed toward the rice mill outlet of the milling mill, and remains more smoothly and efficiently. Various effects that cannot be obtained at all with conventional rice milling machines can be obtained.

    In addition, the discharging operation mechanism of the rice milling machine is composed of a residual rice discharging lever arranged at a proper position, a switching shaft interlocked therewith, and a suction switching arm and a ventilation switching arm that can be interlocked with the switching shaft, The suction switching arm is connected to the suction switching valve of the suction switching chamber, and the ventilation switching arm is connected to the ventilation switching valve of the sending switching chamber, so that no electrical or mechanical drive device is required, and the residual rice Switching operation can be performed only by operating force to the discharge lever, and by operating one residual rice discharge lever, both the suction switching valve and the air blowing switching valve can be operated synchronously and interlocked, which is economical and troublesome In addition, there is an advantage that the maintenance performance is excellent.

In implementing the present invention having the configuration as described above, the best or desirable mode will be described.
The milling mechanism scours brown rice or glutinous rice supplied from a hopper or an alternative brown rice supply source, etc., separates unnecessary components such as rice bran and rice bran, and can be processed into white rice. It has a function that allows the degree of milling of the polished rice to be adjusted freely and appropriately by the degree adjustment mechanism. More specifically, it has a milling roll loosely inserted in a scouring net placed in the milling chamber. , Brown rice or glutinous rice is continuously supplied between the rotationally driven whitening roll and the scouring net, friction is applied to the passing process, and the cocoon and rice bran are separated and removed from the rice to allow whitening treatment. As shown in the examples to be described later, the brown rice or milled rice feed side of the milled roll is provided with a milling chamber serving as a supply side of the milled rice, a brown rice supply port of the hopper and a shutter thereof on the base end side. On the other side Forming a rice outlet, on the lower side of the bran-removing network, sucking emissions such as bran or rice discharged, it should be assumed that we arranged bran collecting unit to allow recovery.

    The hopper functions to store a predetermined amount of brown rice, glutinous rice, etc., and to supply a certain amount of them in the milling room, and opens a brown rice (or glutinous rice) supply port at the lowermost end. In addition, a shutter that can open and close the supply port must be provided, and the shutter can be manually opened and closed by operating an operation portion arranged at a suitable position outside the rice milling machine body.

    The whiteness adjustment mechanism gradually applies the desired pressure to the rice to be processed and whitened and processed while being moved by the transfer force by the rotational drive of the whitening roll from the exit of the milling room, and adjust the state of the whitened rice appropriately. By properly controlling the discharge, the function of controlling the intensity of the whitening process can be controlled freely.

It is desirable that the generated pressure of the pressing force source be released and suppressed by a resistance handle that can be operated from the outside of the main body, but the resistance plate is moved forward and backward by operating the resistance handle to reduce the pressing force. Control too In addition, when a pressing force exceeding an allowable range is applied to the resistance plate between the resistance handle and the resistance plate, a safety spring that releases the pressing force is interposed. The pressing function and the safety function can be incorporated.
