[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a rice sharpener that is polished with anhydrous water.
[0002]
[Prior art]
In general, rice is washed to cook rice. For example, a commercial grain washing apparatus is configured as shown in FIGS. Hereinafter, the configuration will be described.
[0003]
FIGS. 13 to 15 show the rice drain valve device 105 and the drainage system, and a cylindrical drainage jacket 123 is attached to the lower part of the rice washing tank (not shown), and the drainage jacket 123 is drained. The pipe 124 is inserted and connected. The drainage jacket 123 is concentric with the rice washing tank, and a cylindrical strainer 125 is concentrically accommodated in the drainage jacket 123. This strainer 125 allows many foreign substances such as water and rice cake to pass but does not allow rice to pass. A strain hole 125A is formed.
[0004]
The strainer 125 has an upwardly expanding cylindrical shape, and an upper end opening edge of the strainer 125 is externally fitted to a lower end opening edge of the rice washing tank, and a lower end opening edge of the strainer 125 is placed on the seal member 126. By being positioned by the shape receiving tool 127, it is concentric with the drainage jacket 123 and can be taken out from the drainage jacket 123.
[0005]
The seal member 126 is placed on a dish-shaped retainer 128 having a peripheral flange, and the retainer 128 is connected by rotating the lock lever 129 in the direction of arrow A with the pivot pin 129A as a fulcrum. The seal member 126 can be pressed against the lower edge of the drainage jacket 123 via the ring 130 and tightened, and by rotating in the direction of the arrow B, the coupling ring 130 is disengaged to seal the receiver 127. Together with the member 126, the retainer 128 can be removed from the drainage jacket 123.
[0006]
The rice discharge port provided at the bottom of the rice washing tank is constituted by an inner hole 126A of the seal member 126 and a circular hole 128A formed in the retainer 128, and is discharged by a conical rice discharge valve 109 provided on the valve shaft 108 that moves up and down. The rice port constitutes a rice draining valve device 105 that can be opened and closed.
[0007]
The rice drain valve 109 is provided with a lock means 131 for positioning and preventing the rice drain valve 109 in the axial direction by inserting the rice drain valve 109 into the valve shaft 108. The lock means 131 is engaged by a spring 132. A rotatable lock lever 133 urged in the mating direction, and a cam 134 that rotates and retracts the lock lever 133 in the release direction against the spring 132 by inserting the rice drain valve 109 into the valve shaft 108. , And an axial positioning portion 135, which is attached to the bottom of the rice removal valve 109.
[0008]
Specifically, a valve rod insertion hole 109A is formed through the center of the rice removal valve 109, and a step 108B is formed in the middle of the lower side of the valve rod insertion hole 109A. It has an O-ring 108A that seals in a state of being inserted into the rod insertion hole 109A, and has a step portion 108B that engages with the step portion 135A in the axial direction, and both step portions 135A and 108B serve as an axial positioning portion 135. In addition, a lower narrow cam 34 is formed at the lower end of the valve stem 108 via a constricted portion 108C.
[0009]
In an apparatus that removes rice bran and separates rice grains and rice bran, the rice washing process is an important process that determines the taste of cooked rice after cooking, and is a very time-consuming process. Therefore, there are many devices that automate this rice washing process and save labor.
[0010]
However, those that stir water and rice by mechanical force are likely to damage the rice, and the water mixed with rice bran cannot be quickly separated from the rice, and the rice has absorbed the smelly water and cooked rice Will become rice with a bad smell, and the fatty acid contained in the rice cake will be oxidized to increase the warming odor. In addition, there are some which rub rice together with water pressure in running water, but a large amount of water is required, and it causes pollution of sewerage.
[0011]
In addition, although there is wash-free rice sold with the rice cake removed, wash-free rice using water is dried and distributed after using water, so the taste is inferior. The very large scale and the use of rice bran are difficult to handle as general household and commercial equipment, and the system using only non-washed rice is relatively simple, but there is a problem with the taste performance of the non-washed rice itself. there were.
[0012]
In addition, the rice drain valve 109 must be detachable for cleaning or the like, but the mechanism for fixing the valve stem 108 becomes complicated, and the valve stem 108 is fixed with a simple configuration so that the rice drain valve 109 can be easily installed. A configuration for fixing to the rod 108 has been desired. Moreover, when operating the lever of the rice removal valve 108 with a finger, the end face of the spring 132 was caught by a hand (for example, refer patent document 1).

[0014]
[Problems to be solved by the invention]
As mentioned above, it is desirable not to use water or water as much as possible, because when the rice is soaked in water in the washed rice, the rice bran component once dissolved in the water will be absorbed again. Since the water-absorbed rice becomes brittle, it is very difficult to control the mechanical force by applying mechanical force such as stirring to the water-absorbed rice.
[0015]
Also, even if water is not used, the brush alone can remove the pieces of rice cake remaining on the surface of the rice grain, but it is not suitable for removing the portion containing the rice cake component that covers the surface of the rice grain. The water tends to become cloudy, and it cannot be said that the rice is sufficiently washed. Furthermore, in the structure of the rice mill by the mechanical force, the power to remove the milled rice bran is too strong, so that the starch cells on the surface of the rice grain are easily damaged.
[0016]
Therefore, by efficiently promoting the circulation of the rice grains in the container without using water, the force acting on the rice grains can be uniformly and relaxed even if the amount of treatment is large or small, and the rice grains are not damaged. It has been desired to remove only the surface wrinkles, and in particular to easily attach and detach the rice drain valve of the rice drain valve device.
[0017]
The present invention solves the above-mentioned conventional problems. After separating rice cake on the surface of the rice without using water, the rice cake is collected without using a rice bag or a paper pack, and the rice cake moving path. It is intended to make it easy to clean when wrinkles adhere to the surface.
[0018]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the present invention achieves the above-described purpose by a polishing unit for polishing and separating the rice surface and the like, a discharge unit that seals the lower surface of the polished rice unit and opens the rice at the time of rice removal, and opens and closes the discharge unit.

The guiding part 30 is provided at the lower part of the outer periphery of the discharge part 5 and comprises a curved surface 32 that guides the rice flow upward from the lower part of the outer periphery. The curved surface 32 of the guiding portion 30 is set so that the rice can easily move upward along the curved surface 32 on the inner peripheral surface of the polished rice portion 4.
[0034]
The rice washing drum 12 is fixed by the shaft 9 and rotates. The outer peripheral portion of the discharge portion 5 fixed to the central shaft 21 is in close contact with the guide portion 30. An elastic body may be sandwiched between the contact portions to further improve the adhesion. The discharge drive unit 32 is configured to push the central shaft 21 downward. The upper plate 33 covers the upper surface of the rice washing drum 12, and has a curved surface portion 34 for guiding rice to the inner peripheral side of the polished rice portion 4.
[0035]
Next, the discharge drive unit 32 is configured as shown in FIG. 3, and the discharge unit 5 is fitted to the central shaft 21. The upper end of the center shaft 21 is connected to the discharge plate 41 by the rotation shaft 40. The discharge plate 41 is rotatably supported on the discharge plate base 50 by a discharge plate shaft 42. A micro switch 43 is disposed on the lower surface side of the other end 45 of the discharge plate 41, and the discharge plate 41 is pushed downward by the position of the cam 44 to operate the micro switch 43.
[0036]
At the cam position shown in FIG. 3, the microswitch 43 is in an OFF state and the discharge plate 41 is stopped. The cam 44 is rotated by a cam motor 46. The cam motor 44 is fixed to the discharge plate base 50. The discharge plate shaft 42 is also fixed to the discharge plate base 50. On the other hand, the lever plate 47 is rotatably supported by a lever plate shaft 48, and the lever plate 47 is pulled in the clockwise direction by a coil spring 49 on the upper surface.
[0037]
Here, the rice removal plate shaft 42 is fixed to the discharge plate base 50 with an E-ring 62, as shown in FIG. Thereby, space saving and assembly can be simplified.
[0038]
Next, as shown in FIG. 5, when the cam 44 rotates counterclockwise and the other end 45 becomes free, the discharge portion 41 and the central shaft 21 are heavy, so the discharge plate 41 rotates counterclockwise. And abuts against the discharge plate base 50. This position is the lowest point of the discharge unit 5. At this time, the lever plate 47 is rotated clockwise by the force of the coil spring 49. FIG. 6 is an enlarged view of this state.
[0039]
The tip 52 of the lever plate 47 is fitted with a projection 53 formed by a projection plate 51 fixed to the discharge plate 41. The protruding plate 51 is fixed to the discharge plate 41 with screws 54 or the like. In this state, even if the discharge portion 5 is moved upward, the protrusion 53 formed by the protrusion plate 51 is engaged with the tip 52, so that the discharge plate 41 cannot rotate clockwise. That is, the central axis 21 does not move. At this position, the polished rice is discharged to the bottom.
[0040]
Next, as shown in FIG. 7, when an instruction to rotate the cam 44 in the counterclockwise direction is given, the cam tip 60 pushes the upper surface of the lever plate 47. The lever plate 47 gradually moves counterclockwise, and the tip 52 is separated from the projection 53 formed by the projection plate 51. This detailed view is shown in FIG.
[0041]
When the projection 53 formed by the projection plate 51 is separated from the tip 52, the discharge plate 41 can freely rotate. However, since the discharge portion 5 and the central shaft 21 are heavy, the discharge plate 41 is stationary. When the cam 44 further rotates and returns to the original state shown in FIG. 3, the cam 44 is pulled upward. This position is the position where polishing can be performed at the uppermost position of the discharge portion 5. That is, this state is the polished state shown in FIG. The rice is not leaking from the discharge unit 5.
[0042]
In this embodiment, the tip 52 of the lever plate 47 is fitted with a projection 53 formed by a projection plate 51 fixed to the discharge plate 41. However, as shown in FIG. And the end 52 of the lever plate 47 may be fitted to reduce the number of assembling steps.
[0043]
Next, as shown in FIGS. 10 to 12, the locking means 72 is used to position the discharging portion 5 in the axial direction and prevent the locking when the discharging portion 5 is inserted into the central shaft 21. Reference numeral 72 denotes a rotatable lock lever 73 urged in the engaging direction by the coil spring 70 and an operation of inserting the discharge portion 5 into the central shaft 21 to release the lock lever 73 against the coil spring 70. And a cam 74 that pivots and retracts, and an axial positioning portion 75, and is attached to the bottom of the discharge portion 5. Specifically, a valve rod insertion hole 76 is formed through the center of the discharge portion 5, and a lower narrow cam 74 is formed at the lower end of the central shaft 21 via a constricted portion 77.
[0044]
The coil spring 70 has a hook portion tip 71 provided on the upper surface of the lever 69. For this reason, it is not caught in a hand.
[0045]
The operation in the above configuration will be described. Rice grains of polished rice for the purpose of washing rice are introduced into the polished rice unit 4. By operating an operation switch (not shown), the motor 8 starts to rotate, and the rice washing drum 12 fitted to the shaft 9 is rotated. The rice at the bottom of the polished rice section 4 is given a centrifugal force by the rotation of the rice washing drum 12, and the rice grains are pressed against the side surface of the rice washing drum 12, so that they are raised along the side surface in order.
[0046]
Since the rice is continuously pushed up to the set height, the rice grains that have risen higher than the tip of the polished portion 4 lose their force and fall free or collide with the upper plate 33 of the polished portion 4. Return to the bottom. The rice grains move again to the side by centrifugal force, and the same operation is repeated. That is, the rice at the bottom of the polished rice unit 4 is given centrifugal force, and the rice grains are pressed against the side surface of the rice washing drum 12 and circulated.
[0047]
On the other hand, the circulation described above promotes the friction between the rice grains by centrifugal force while rising between the side wall of the separating portion 14 and the brush 13, and the tip of the brush 13 enters the surface groove of the rice, Scrape the powder on the rice surface. The separated soot and the like are discharged into the closed space 16 of the outer hopper 15 from the hole of the separating portion 14. After that, the suction motor (not shown) sucks the cyclone 6 and the soot is collected in the soot collection container 35, so that the soot and the rice are separated and washed with anhydrous water.
[0048]
Here, by removing the screw 39, the upper plate 33, the outer hopper 15, the polished rice portion 4 and the like can be separated from the rice sharpener main body 1, and each portion can be easily cleaned. Further, since the exhaust of the suction motor is returned to the outer hopper 15 via the pipe 41, a strong swirling flow is generated in the cylindrical donut-shaped closed space 16 in the outer hopper 15. The soot that has come out to the 16 side is blown away, and the soot can be recovered efficiently.
[0049]
Regarding rice discharge, after washing the rice, the rice is stationary in the polished rice section 4, but when the central shaft 21 is pushed downward by the discharge drive section 32, the close contact section between the discharge section 5 and the guide section 30 opens, By making the discharge part 5 into a convex cone, the rice sequentially slides down the conical slope and falls to the rice receiving part 11. At this time, since the inclination of the cone is set to an angle at which no rice remains, there is no remaining rice. When the rice washing drum 12 is rotated, it can be discharged even faster.
[0050]
Next, replacement of the discharge unit 5 will be described. The discharge part 5 fixed to the central shaft 21 is separated from the guide part 30 and can be easily removed when the discharge drive part 32 is in the state shown in FIGS. 5 and 6. When cleaning or the like is finished and the discharge portion 5 is attached to the central shaft 21, since the central shaft 21 is fixed, the discharge portion 5 does not move even when a slight load is applied to the discharge portion 5. It can be easily attached without touching. When the cam 44 is rotated after the attachment, the protrusion 53 is unlocked and the discharge plate 41 becomes free, so that the state shown in FIG.
[0051]
As described above, the discharge portion 5 can be easily attached and detached while the central shaft 21 is locked. Further, due to the weight of the central shaft 21 and the discharge portion 5, the central shaft 21 and the discharge portion 5 are easily in the state shown in FIG.
[0052]
Further, the projection 66 provided on the discharge plate 41 has the same action as described above. Further, by configuring the projection 66 with the projection plate 51, when the projection 66 is likely to have a long service life, if the projection plate 51 is used, it can be easily replaced and returned to the initial state. Become. If a material with rigidity is selected for the protruding plate 51, the service life is further extended.
[0053]
Further, since the cam 44 is rotatably supported by the discharge plate base 50 and the cam shaft 64 is supported by the discharge plate base 50, the discharge plate 41 is not cantilevered as shown in FIG. It can withstand a large load because it is supported by holding. In addition, the life is extended and stabilized. Further, when the discharge plate shaft 42 is fixed to the discharge plate base 50, the number of steps can be reduced by using the E ring 62.
[0054]
In addition, the coil spring 70 is often made of a stainless steel material or the like, and has an edge of the end face and sometimes hits the hand. However, by providing the end face on the upper surface side not touching the hand, You can protect your hands.
[0055]
