[Technical field to which the invention belongs]
The present invention relates to an improvement of a polishing member, particularly in a polishing machine that further removes a koji or a paste powder layer from polished rice that has been polished with a polishing machine or from commercially available polished rice.
[0002]
[Prior art]
The present inventors removed a koji or paste powder layer from milled rice milled with a rice mill or commercially available milled rice, and obtained a non-washed rice that can be cooked without having to grind the rice with water. As shown in FIG. 1, as a polishing member for a rice machine (wash-free rice machine), as shown in FIG. 1, a rotating disc 3 attached to the rotating shaft 2 and also attached to the rotating shaft 2 and rotated together with the rotating disc 3. A polished rice member 1 comprising a cylindrical body 4 was developed (see Japanese Patent Application No. 2000-80827). Moreover, as shown in FIG. 2 and FIG. 3 (plan view), a rice cake having a ridge 3a provided on the upper surface of the rotating disk 3 to improve rice circulation ability has been developed (see Japanese Patent Application No. 2001-027532). A drive shaft of a motor, which will be described later, is fitted in the hole of the rotating shaft 2, the cylindrical body 4 is connected to the rotating shaft 2 via a connecting plate 5, and the outer peripheral surface thereof has a brush shape.
[0003]
The polished rice member 1 is installed in a polished hopper of a polished rice machine, for example, as shown in FIG. 5 (see Japanese Patent Application No. 2000-239223). This rice polishing machine 6 is installed in the lower part of the rice storage tank 7 and the rotary weighing and cutting device 8, and is installed in the rice vessel 9 and the rice hopper 10 arranged inside thereof. It consists of a polished rice 1 and the like.
The rotary weighing and scissor cutting device 8 includes a scissor cutting structure portion 11, a rotary weighing portion 12, and a weighing receiver 13, and a trough cutting portion (outlet) 11 a is formed in the trough cutting structure portion 11. Has a cylindrical hole (measuring rod) 12a penetrating vertically, and an opening 13a is formed in the metering receiver 13. When the rotary weighing unit 12 is rotated horizontally by a predetermined angle with a motor (not shown) or the like while the polished rice is put in the rice storage tank 7, the rice that has entered the weighing basket 12a through the outlet 11a is cut off. When the weighing basket 12a matches the opening 13a, the rice in the weighing basket 12a flows down into the lower polishing hopper 10 through the opening 13a.
[0004]
The polished rice hopper 10 is a removal part in which a large number of small holes are formed on almost the entire side wall of the polished rice hopper 10, and the rice bran and paste layer peeled from the polished rice are discharged into the rice bran container 9 through the small holes. . The polishing rice discharge opening 14 of the polishing rice hopper 10 is normally closed by a valve body 15 that is advanced and retracted by a solenoid (not shown).
The rice bran container 9 is formed with a polished rice opening 16 serving as a rice discharge passage at a location corresponding to the rice polishing discharge opening 14 and a rice bran discharge opening 17 serving as a rice cake discharge passage at another location. It is connected to a suction device (not shown).
The outer diameter of the rotating disk 3 of the polished rice member 1 is set to be slightly smaller than the inner diameter of the polished rice hopper 10 (there is a minute gap that does not allow rice to bite), and the rice is always on the rotating disk 3. The top surface is set to the same height or slightly higher than the polished rice discharge opening 14. A motor drive shaft 18 (not shown) is fitted in the hole of the rotary shaft 2.
[0005]
When the motor of the polished rice member 1 is operated at the same time and the suction device is operated at the same time, the rice is stirred and polished while circulating (indicated by arrows) in the polished rice hopper 10. The state of circulation is shown in FIG. That is, as described in the aforementioned Japanese Patent Application No. 2000-80827, the rice on the rotating disk 3 is pushed outward by centrifugal force, and the rice that has reached the outer circumference is studied by the pressure of the rice being pushed one after another. The rice that has risen through the space between the hopper 10 and the cylindrical body 4 and then reached the upper end is released from the pressure and flows down toward the center of the cylindrical body 4, and then returns to the rotating disk and is pushed outward. . In the course of this circulation, the rice is subjected to a rice polishing action when it rises between the rice hopper 10 and the brush-like outer peripheral surface of the tubular body 4. On the other hand, the paste powder layer peeled from the rice passes through the small hole of the polished rice hopper 10 by the suction device and enters the straw container 9 and is sucked and discharged from the straw discharge opening 17. When the planned level of polishing is reached, the valve body 15 moves backward, and the rice stirred in the polishing hopper 10 is discharged through the polishing discharge opening 14 and the polishing opening 16 by centrifugal force.
[0006]
[Problems to be solved by the invention]
According to the above rice milling machine, the milled rice and the paste powder layer are removed from the milled rice, so that it is possible to obtain wash-free rice that can be cooked without the need for rice polishing using water. Polished rice consists of two processes: a grinding process for peeling the rice cake and paste powder layer from the rice, and a finishing process for removing the powder adhering to the rice surface after peeling. In the conventional polished rice member, the brush-like portion is composed of a single material, and the two steps of polishing rice are performed simultaneously. For this reason, when using a brush suitable for the peeling of wrinkles and glue powder layers (generally with a harder hair), the treated rice will have a slightly increased amount of powder adhering to it, which is suitable for removing the powder ( In general, when the hair is soft, the rice after treatment will remain incompletely removed, such as rice bran and paste layer, or it will take a lot of time to remove, and further improvement has been desired. . An object of the present invention is to solve such problems.
[0007]
[Means for Solving the Problems]
It is intermediate between the two polishing processes, namely, the grinding process that peels the rice cake and paste layer from the rice, and the finishing process that removes the powder adhering to the rice surface after peeling. It must be hard hair, and this will not improve the polishing performance. In order to further improve the polishing performance, it was found that the regions of the brush-like portions were divided in the vertical direction, and the brushes in each region were specialized in two processes. The present invention has been made based on this finding. That is, the polishing member according to the present invention is installed inside the polishing hopper and covers the bottom surface of the rotating disc, and is installed with a gap above the rotating disc, and is concentric with the rotating disc and rotates. It consists of a cylindrical body that rotates with a disk and has a brush-like outer periphery, and the outer diameter of the rotating disk is set slightly smaller than the inner diameter of the polished rice hopper so that the rice does not fall between the two There is a minute gap to the extent that rice is not bitten, the shape of the brush-like part is different in the vertical direction of the cylindrical body, and the lower region is a region where the ability to grind rice is relatively high And This is achieved by forming the lower area brush harder than the upper area brush. For this reason, the lower area of the brush-like part has a larger hair diameter than the upper area, increases the rigidity of the hair, increases the number of hairs per unit area, shortens the hair length, etc. Or, by combining two or more of these elements, the main purpose is to peel the rice bran or paste layer from the rice. The upper region of the brush-shaped part is a region opposite to the lower region, and is a region whose main purpose is to remove the powder adhering to the rice surface. The shape of the brush-like portion may be changed stepwise in the vertical direction, but is not limited thereto.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
6 and 7 show a polished rice member 21 according to the present invention, and a rotating disk 23 attached to a rotating shaft 22 and a cylindrical body 24 which is also attached to the rotating shaft 22 and rotates together with the rotating disk 23. Consists of. In the present embodiment, the cylindrical body 24 is a cylinder, but this may be a polygonal cylinder. The rotating disk 23 is attached to the rotating shaft 22 via a disk-shaped pedestal 25. The pedestal 25 has a role of supporting a connecting plate 26 described later, but is not essential. The cylindrical body 24 is connected via a pair of connecting plates 26 extending in the radial direction from the rotating shaft 22, and is positioned above the rotating disc 23 with a gap. In this embodiment, a brushed rice brush 28 by flocking is provided on the outer periphery of the cylindrical body 24. However, the brush is not limited to flocking as long as the hair is raised, so-called “brush shape”, and any brush can be used. it can. The connecting plate 26 is plate-shaped and tilts freely with respect to the rotational direction (same as the arrow in FIG. 3), and this acts to push down the rice that has entered the cylindrical body 24 and promote its circulation. Here, the term “advanced with respect to the rotation direction” means that the upper side of the connecting plate 26 is in a position advanced from below with respect to the rotation direction (inclined so that the upper side is forward).
[0009]
On the upper surface of the rotating disk 23, a protrusion 27 is provided from the center side toward the outer peripheral side. The protrusion 27 extends from the outer peripheral surface of the pedestal 25 so as to be curved in a delayed manner with respect to the rotation direction. It acts to push the rice on top to the outer periphery. Here, “extending in a curved manner without delay” means that the outer peripheral side of the ridge is delayed from the central side with respect to the rotational direction (extends backward from the radial direction r (see FIG. 3)). The protrusion 27 is for improving the circulation ability of rice and is not essential in the present invention.
[0010]
The polished rice brush 28 includes a brush seat 28a, a grinding brush 28b, an adjustment brush 28c, and a finishing brush 28d. Each brush seat 28a is a pedestal for bonding and fixing hairs or for flocking.
The grinding brush 28b is a relatively hard brush, and this is a region where the rice cake and the paste powder layer are peeled off from the rice. A stiff brush increases the hair diameter, increases the rigidity of the hair, increases the number of hairs per unit area, shortens the hair length, or any two or more of these elements Can be combined.
The finishing brush 28d is a relatively soft brush, and this is an area for removing the powder adhering to the rice surface. The soft brush can be made of a hair having the opposite hair to the grinding brush 28b or a combination thereof.
The adjustment brush 28c is made of an intermediate hair between the grinding brush 28b and the finishing brush 28d. This is an area where the grinding amount is adjusted or rough finish is made according to the hardness of the rice to be polished (hard rice / soft rice). In addition, although it is desirable to provide the adjustment brush 28c, it is not essential in the present invention.
[0011]
FIG. 6 shows an example of a method for attaching the brush portion of the polished rice member according to the present invention. The grinding brush 28b, the adjustment brush 28c, and the finishing brush 28d are fitted into the cylindrical body 24 from below, in which the brushes are planted on the annular brush seat 28a. Such horizontal division may be performed by an arbitrary number. The grinding brush 28b, the adjustment brush 28c, and the finishing brush 28d may all be planted in one brush seat 21a.
FIG. 7 shows another example of the method of attaching the brush portion of the polished rice member in the present invention. From the bottom, a polished rice brush 28 in which a grinding brush 28b, an adjustment brush 28c and a finishing brush 28d are planted is formed and inserted into a groove formed on the outer periphery of the cylindrical body 24. This method may also be divided by an arbitrary number.
By dividing in this way, replacement and repair are facilitated when the brush is worn or dropped or the brush seat 28a is damaged. In addition, the grinding amount and finishing degree can be easily adjusted. It should be noted that even if the brush is directly planted on the cylindrical body 24, nothing can be done. Furthermore, it is not necessary to clearly divide the grinding brush 28b, the adjustment brush 28c, and the finishing brush 28d from below, and the hair quality may be gradually changed.
[0012]
Similar to the polished rice member 1 (see FIGS. 4 and 5), the polished rice member 21 has a cylindrical side wall and has a small number of small holes formed in at least a part of the side wall and the bottom wall. It is installed in a polished rice hopper having a section and rotates. When this polished rice member 21 is used, the lower portion of the brush first peels off the wrinkles and paste powder layer, etc., adjusts the amount of grinding and rough finishes in the middle region, and adheres to the rice surface in the upper region. Remove and finish. In this way, polishing can be performed efficiently in a short time.
[0013]
【The invention's effect】
According to the polished rice member of the present invention, the rice bran and paste powder layer can be efficiently peeled and removed from the surface of the rice, and the polished rice performance can be greatly improved. Along with this, it has become possible to obtain wash-free rice having a good finish with no powder adhering to the surface after the treatment. Moreover, the effect that processing time was shortened was also acquired.
