Description

  TECHNICAL FIELD The present invention relates to a dry-type non-washing rice production apparatus that applies a mechanical removal force such as a brush to polished white rice to remove the cocoon layer on the surface of white rice, and in particular, there is no change in the mounting position of the hopper and product discharge cylinder. The present invention relates to a rice washing apparatus.

  Some rice bran layer (glue layer) remains on the surface of white rice that has been brown rice polished by a rice mill, and it is necessary to sharpen the rice before cooking. In view of such a situation, it is necessary to remove the rice bran layer (glue layer) remaining on the surface of the white rice to the extent that it has been sharpened with rice, and it is not necessary to sharpen the rice before cooking rice. Wash-free rice production equipment is provided.

  As a manufacturing method of the non-washing rice in the conventional non-washing rice manufacturing apparatus, there were (1) hydrofinishing method, (2) special finishing method, and (3) dry finishing method. Hereinafter, it demonstrates in order.

(1) Hydrofinishing method The hydrofinishing method is a drying process in which the rice bran layer remaining on the white rice surface is washed away by washing with water, and immediately after that, the dried rice is dehydrated and dried to remove moisture. It is a method to do. Since this method uses water to remove the rice bran layer (glue layer) on the surface of white rice, it is washed without using rice sharpening before cooking rice, but it is washed using water in the washing-free rice production process. Therefore, special hygiene management is required, such as excess water is absorbed in white rice and mold is generated in white rice. In addition, it is necessary to clean rice bran and white rice adhering to the inside of the apparatus with water after the washing-free rice is produced, and there are many maintenance burdens. In addition, the mechanical equipment also requires dehydration and drying equipment after washing and wastewater treatment equipment, so that the entire manufacturing equipment has a complicated configuration and the cost of the whole equipment increases.

(2) Special finishing method In the special finishing method, a slight amount of water is added to the polished white rice to soften the surface koji and make it easy to peel off. After the rice bran layer is adsorbed on the rice bran adsorbent, the white rice and the rice bran adsorbent are separated and sorted to finish washing-free rice. Unlike the hydrofinishing method using a large amount of water, there is an advantage that hygiene management such as generation of mold due to moisture absorbed by white rice becomes unnecessary. Also, maintenance inside the apparatus is reduced. However, a heating device that preliminarily sterilizes the rice bran adsorbent and a sorting device that separates and sorts the white rice and the rice bran adsorbent are necessary as incidental facilities, which increases the cost of the entire facility. In addition, the soot adsorbent can be recycled and reused, but the soot adsorption effect is reduced during production, so it is necessary to replenish new ones periodically, and the cost of washing-free rice increases accordingly. There are drawbacks.

(3) Dry finishing method The dry finishing method is a manufacturing method in which the mechanical removal force of a polished rice is applied to the polished white rice and applied to the dry rice polishing equipment that removes the wrinkle layer on the surface of the white rice. is there. This type of polishing apparatus is composed of a cylindrical part of the net having a perforated portion for discharging the rice cake and a member for polishing, and an axial direction of the net of the removal net inside the removal net. A rice bran layer on the surface of white rice that cannot be removed with milled rice while transferring white rice through a white rice transfer path formed between the scouring net and the trochanter. It has a structure to scrape off the layer. In some cases, the removal net is formed in a substantially cylindrical shape by only a porous member, and a brush is attached to a trochanter rotating inside the net. As dry-type non-washing rice production apparatus using such a dry finishing method, for example, those described in Patent Documents 1 and 2 are known.

  Compared with the above-mentioned hydrofinishing method and special finishing method, the dry washing-free rice production device has the advantages that the entire device is simple and the production cost is low. However, compared with non-washed rice treated with the hydrofinishing method or special finishing method, the non-washed rice treated with the dry finishing method is present on the surface of the white rice, although the straw layer adhering to the surface of the white rice is removed. However, since the soot layer entering the longitudinal groove line (concave groove portion) is not completely removed, there is a problem that the quality as non-washed rice deteriorates.

For this reason, Patent Document 1 discloses an apparatus in which a dry processing machine is built in two stages, and Patent Document 2 discloses an apparatus in which three washing-free rice production apparatuses are connected in series. That is, in these apparatuses, the white rice once processed through the machine is again passed through the machine a few times to improve the quality level of the non-washed rice. However, if such a two-stage system or a multiple-unit joint system is used, there is a drawback that the mechanical device becomes larger and the cost becomes higher. In addition, when white rice is passed through the processing machine 2 to 3 times, stress is applied to the white rice, so the crushed rice increases, and the temperature of the white rice during processing becomes high.

  As described above, although there are three methods for producing the conventional washing-free rice production apparatus, the washing-free rice production apparatus is expensive and the maintenance burden is increased in the hydrofinishing method or the special finishing method. In addition, the entire equipment becomes large and expensive. In addition, the complex equipment configuration makes it unsuitable for small rice cereal stores and producers.

  On the other hand, the dry finishing method does not use water and soot adsorbents, does not require any associated equipment, and saves the labor of hygiene management. Although it has the advantage that it can be used easily compared to the above two methods, it is patented. In the apparatus of the conventional structure disclosed in Documents 1 and 2, the rice bran layer (glue layer) remaining on the surface of the white rice cannot be completely removed unless it is a two-stage system or a multi-unit system, and before cooking rice We cannot expect the finish of washing-free rice to the extent that the rice sharpening work can be omitted. Therefore, although it is cheaper than the washing-free rice production equipment of the hydrofinishing method and special finishing method, the equipment cost of the small rice grain shop and production farmer is still expensive, and a wide installation place is required, The big burden is the disadvantage. In addition, none of the conventional dry-type washing-free rice production apparatuses described above particularly considers connection with other apparatuses such as a rice mill in the preceding and subsequent processes, and therefore, for connection or cooperation with other apparatuses or for operation. From the viewpoint of operation or maintenance, the direction of the rice milling apparatus (Patent Document 1) or the rice polishing apparatus (Patent Document 2) itself changes, and there are many problems such as requiring a large installation place. Therefore, in addition to the apparatus being compact, a dry-type non-washing rice production apparatus that does not require an installation place is desired.

  The present invention has been made in view of such problems, and the purpose of the present invention is to completely remove the rice bran layer (glue layer) remaining on the surface of white rice if it is not washed with a two-stage system or a multi-unit joint system. Eliminates the disadvantages of the dry-finished rice-free rice-making machine, and makes it possible to finish the wash-free rice by completely removing the glutinous layer on the white rice surface once through the single-stage dry-finishing machine. In addition, even when there is a restriction on the place where such a dry washing-free rice production apparatus is placed, a hopper that receives supply of white rice as a raw material without changing the installation direction of the apparatus itself and a product discharge cylinder from which the processed white rice is discharged By changing the fixing position, it is possible to easily communicate with other equipment such as a rice mill.

The invention according to claim 1 is provided with a rotating shaft, a rotation driving means for rotating the rotating shaft, and one end of the rotating shaft, which transfers white rice supplied from the outside to the other end of the rotating shaft. A first transfer body, a second transfer body provided on the other end side of the rotary shaft, for transferring the white rice transferred from the one end side from the other end side, and discharging the white rice; A plurality of integrally formed third transfer bodies and polishing brushes that are detachably mounted on the rotary shaft between the transfer bodies and the second transfer bodies, and at least outer peripheries of the third transfer bodies and the polishing brushes A cylindrical porous member provided at a predetermined interval on the side of the polishing brush, a cereal cylinder having an inlet opening formed integrally with a lower portion of the porous member, and an upper portion of the porous member A discharge cylinder with an outlet opening formed in the Cylinder and the discharge cylinder is a dry non-bran rice manufacturing apparatus characterized by fixed position coaxially state can be changed.
Wherein the the invention of claim 2, in a dry non-bran rice manufacturing apparatus according to claim 1, before KiAgeKoku cylinder and the discharge cylinder is fixed position coaxially state is changeable quarter turn increments It is a dry-type non-washing rice production apparatus.
According to a third aspect of the present invention, in the dry-type non-washing rice manufacturing apparatus according to the first or second aspect , the discharge cylinder integrally has a product discharge cylinder, and the cereal cylinder has a hopper integrally. It is a dry-type non-washing rice production apparatus characterized by this.

With each of the above configurations, the white rice supplied from the outside to the first spiral body when the rotary shaft is rotated by the rotation driving means is transferred to the third spiral body, and then polished by the polishing brush, It is transferred outward by the spiral. The rice cake removed from the white rice is discharged to the outside through the porous member by the discharging means. At this time, since the transfer speed decreases in the portion of the polishing brush, the surface of the white rice is easily subjected to the polishing action of the polishing brush. Moreover, white rice is repeatedly polished by a plurality of polishing brushes. Moreover, in order to adjust the polishing degree of white rice, the number of third transfer bodies and polishing brushes is adjusted.
Furthermore, since the fixed positions of the cereal and discharge cylinders can be changed, the fixed position can be changed. For example, when polishing polished white rice with a rice mill, it matches the positional relationship between the rice mill and the dry-type rice washing machine. Then, the introduction and discharge direction of this washing machine from the rice mill is set.

According to the dry-type non-washed rice production apparatus according to the present invention, it is possible to finish the non-washed rice by removing the wrinkles that have entered the vertical groove line (concave groove portion) of the white rice with only one pass through the apparatus. In addition to preventing the increase in broken rice and lowering of yield that occur as a result of passing through, the number of third transfer bodies and polishing brushes mounted on the rotating shaft can be changed to improve the quality (characteristics) and taste of white rice Wash-free rice can be easily obtained.
In addition, since the fixed position can be changed while the cereal cylinder and the discharge cylinder are concentric, for example, when polishing polished white rice with a rice mill, the positional relationship with the dry-type washing-free rice apparatus connected to the rice mill Accordingly, the direction of introduction and discharge of the washing-free rice apparatus from the rice mill can be set, and even when there is not enough room for installation, it can be easily set and operated according to the installation situation.

Here, each polishing block can be individually attached to and detached from the rotating shaft 2, and the degree of polishing of white rice can be adjusted by increasing or decreasing the number of the polishing blocks. A specific method for increasing or decreasing the number of polishing blocks will be described later.

  On the outer peripheral side of the whipping spiral part 5, a concentric cerealing cylinder 9 is provided with an appropriate gap from the outer periphery of the whipping spiral part 5. The cereal cylinder 9 is provided with an inlet opening 11 through which white rice flows into the cereal cylinder 9 obliquely from above from a hopper 10 (details will be described later) provided outside the machine case 1. Further, on the outer peripheral side of the discharge spiral part 8 mounted on the upper part of the rotary shaft 2, a discharge cylinder 12 similar to the cerealing cylinder 9 supports the rotary shaft 2 from the vicinity of the lower end of the discharge spiral part 8 from the screwed upper end part. It is provided with a length that is extended by the length of the portion to be performed. The discharge cylinder 12 protrudes from the upper end of the body case 1, and an exit opening 13 through which the cerealed white rice is discharged out of the cylinder is located obliquely downward on the right side on the vicinity of the upper end of the discharge spiral portion 8. The outlet opening 13 has a downward product discharge tube 14 at the front end.

  Between the cereal cylinder 9 and the discharge cylinder 12, a wire mesh 15 formed integrally therewith is provided around the polishing block with an appropriate gap from the outer periphery of the polishing block (brush spiral portion 6 and polishing brush 7). These are arranged concentrically. As shown in FIGS. 3 and 4, the metal strip 15 is formed in a cylindrical shape by opposing and fixing two semi-cylindrical porous members, and an inner peripheral surface thereof has a polishing brush. A plurality of resistors 16 made of a thin and long plate-like body that is convex in the vertical direction (= direction parallel to the rotation axis 2) and is almost the same length as the stripping wire mesh 15 so as to be orthogonal to the rotational direction of FIG. Is provided. Here, as shown in FIG. 4B, the semi-cylindrical porous member has a bent piece 15a whose one end is bent in the radial direction outside the cylinder. As will be described later, in this embodiment, the demetalization mesh 15 can be configured to have a variable inner diameter, and the bent piece 15a is used when the inner diameter of the demetalization mesh 15 is configured to be variable.

  As shown in FIG. 1, a removal chamber 18 surrounded by a partition plate 17 is formed in the body case 1 facing the outer peripheral portion of the removal wire mesh 15. A removal port 19 is provided below the removal chamber 18, and its outlet is connected to suction means 20 (fan or dust collector) outside the body case 1. In addition, a secondary air intake hole (not shown) for taking outside air is provided on the outer periphery of the removal chamber 18 at a position facing the removal port 19.

  A hopper 10 is provided on the right side surface of the machine body case 1, and a hopper outlet 21 is connected to the inlet opening 11 of the cereal cylinder 9. A supply shutter 23 is attached to the hopper supply port 22, and the supply shutter 23 is configured to be opened and closed by an electric drive means 24 (solenoid or motor).

  The cereal cylinder 9 has a structure in which the fixing position can be changed in a concentric state, and the inlet opening 11 is formed from the state fixed to the right side as shown in FIG. The fixed position can be changed in the direction. Corresponding to the position change, the hopper 10 is also configured to be able to change the mounting position to the same position. With this configuration, even when the installation location of the machine is restricted, it can be flexibly connected to other equipment (such as a rice mill).

  The discharge cylinder 12 also has a structure in which the fixed position can be changed in a concentric state, like the cereal cylinder 9. That is, for example, it is possible to change the take-out position of non-washed rice from the state fixed to the right side as shown in FIG. Therefore, even if there is a restriction on the installation location of the machine body, the dry rice can be taken out flexibly.

  Operation of this apparatus and operation of operation stop are performed using the operation switch 25 arrange | positioned at the inclined surface of the body case 1. FIG. The operation of the suction means 20 may be configured to be performed by operating the operation switch 25 or may be configured to be performed by a switch provided in the suction means 20. Further, the present apparatus can variably control the rotation speed of the motor 3 so as to rotate at a plurality of arbitrary or preset rotation speeds, and variably control the rotation speed of the rotary shaft 2 accordingly. The means for performing the variable control is configured by using, for example, an operation control unit configured by an inverter device that converts the frequency of the power supply of the motor 3 and a volume or a select switch provided near the operation switch 25. This can be realized by the rotation speed change control means. Then, by using a volume or a select switch or the like to control the output of the inverter device continuously or stepwise, the rotational speed of the motor 3 can be rotated at an arbitrary or a plurality of preset rotational speeds. Here, the operation of the volume or the select switch can be performed either during the operation of the apparatus or before the operation.

  The schematic operation of the dry-type non-washing rice production apparatus of the present embodiment configured as described above will be described. White rice milled from the rice milling machine in the previous process is supplied from the hopper 10 to the cereal cylinder 9. The white rice sequentially supplied to the cereal cylinder 9 is transferred upward by the cereal helix 5, sent to the brush helix 6 of the polishing block, and further sent to the polishing brush 7 by the brush helix 6. And the white rice grind | polished with the grinding | polishing brush 7 is conveyed upward by the discharge | emission spiral part 8, passes through the exit opening part 13, and is discharged | emitted from the product discharge cylinder 14 outside. Further, the inside of the removal chamber 18 is brought into a negative pressure state by the operation of the suction means 20, and the soot discharged from the removal wire mesh 15 is sucked into the suction means 20 through the removal port 19. At this time, air flows from the secondary air intake hole (not shown) along the outer periphery of the removal metal mesh 15, and soot that tends to adhere to the outer periphery of the removal metal mesh 15 is also removed.

  Here, the supply shutter 23 is closed before the operation of the apparatus, but is held open by the electric drive means 24 after the operation start operation of the apparatus. Moreover, it becomes the operation | movement closed after this apparatus operation stop operation. However, when white rice is supplied in a state where the supply shutter 23 is accidentally opened before starting the operation, and then this apparatus is activated, the white rice accumulated in the lower cereal spiral portion 5 is cerealed at once and the brush spiral portion There is a risk of stagnation in 6 and the inability to cease cerealing. In addition, if white rice remains in the cereal spiral portion 5 after the operation is stopped, it may be mixed with different varieties of white rice during the next operation or the cereal spiral portion 5 may become dirty. In order to avoid this, in this embodiment, the operation of the apparatus is controlled according to the timing shown in FIG. In this figure, (a) is the number of rotations of the motor 3, (b) is the open / closed state of the supply shutter 23, (c) is the lifting helix part 5, the grinding block, the discharge helix part 8 and the lifting side of the outer periphery thereof. This is the amount of white rice present in the white rice transfer path formed by the grain cylinder 9, the stripping wire net 15, and the discharge cylinder 12. That is, after the operation start operation, the supply shutter 23 is closed until the rotation of the rotating shaft 2 by the motor 3 reaches the specified rotation speed (t1), and after the specified rotation speed is reached and stabilized, the supply shutter 23 is moved. Control to open. When the operation of the apparatus is stopped, the supply shutter 23 is closed immediately after the operation is stopped, and the operation of the apparatus is stopped after a lapse of a certain time (t2) until the polishing brush 7 and the brush spiral portion 6 no longer have white rice. Is controlled to be.

  The polishing brush 7 itself has almost no whipping function because resin brushes are planted at high density. Therefore, around the polishing brush 7, the moving speed in the whipping direction decreases, and the surface of the white rice is easily subjected to the polishing action of the polishing brush 7. For this reason, the brushing effect by the polishing brush 7 is increased due to a large speed difference from the polishing brush 7 rotating at high speed. In addition, the density of white rice increases around the polishing brush 7, so that the white rice itself repeatedly revolves around the polishing brush 7 due to the collision between the white rice, and the polishing action by the polishing brush 7 is uniform on the back and front of the white rice surface. Will receive.

  However, even if the moving speed in the cereal direction decreases around the polishing brush 7, if the polishing brush 7 is swung and the white rice swirls on the inner surface of the demetalization wire mesh 15, the polishing brush 7 is sufficiently polished. It becomes difficult to receive. Therefore, in the present embodiment, as described with reference to FIGS. 3 and 4, the convex resistor 16 is provided on the inner surface of the stripping metal net 15 so as to be orthogonal to the rotation direction of the polishing brush 7, and the polishing brush 7. It is prevented that it becomes difficult to receive polishing by. FIG. 6 shows a state in which the turning of the white rice 26 is suppressed by the resistor 16.

  That is, the white rice 26 to be cerealed while being swung by the brush spiral portion 6 and the polishing brush 7 is first decelerated in the cerealing direction by the polishing brush 7, and the resistance of the wire removal mesh 15 is reduced. Since the turning speed in the turning direction is also suppressed by the body 16, the polishing by the polishing brush 7 can be sufficiently received.

As described with reference to FIG. 2, the present embodiment has a structure in which a plurality of polishing blocks, which are combinations of the brush spiral portion 6 and the polishing brush 7, are arranged on the rotary shaft 2. As a result, the brushing as described above is repeated for the number of the polishing brushes 7 arranged.
By the way, there are many streaky vertical groove lines (concave groove portions) 27 as shown in FIG. 7 on the surface portion of the white rice 26, and it is difficult to remove the wrinkles that have entered the vertical groove lines (concave groove portions) 27. there were. However, in the present embodiment, the combination of the brush spiral portion 6 and the polishing brush 7 having a high brushing effect is used to uniformly apply the polishing action over the entire surface of the white rice, and the same polishing action is achieved by the arrangement of a plurality of blocks. Is repeatedly received, so that the soot that has entered the longitudinal groove line (concave groove portion) 27 before passing through the final polishing brush 7 is also removed.

  On the other hand, if the polishing action is too strong, among the irregularities on the surface of the grains, the projections may be excessively polished and the surface may be damaged. As a result, when the rice was cooked after the washing-free rice treatment, the quality of the washing-free rice sometimes deteriorated, for example, the taste was lowered or the surface was damaged, and the gloss of the white rice surface was lost and the visual feeling was lowered. Therefore, in this embodiment, the gap between the outer side of the polishing brush 7 and the inner surface of the stripping wire mesh 15 is made slightly larger than the thickness of the rice grains, so that it is impossible to force the stripping wire mesh 15 that is harder than white rice. It is also possible to prevent scratching the surface of white rice without applying pressure. Further, the convex resistor 16 provided on the inner surface of the stripping wire mesh 15 has an action of saving extra turning of the white rice 26 accompanying the turning of the polishing brush 7, and this also prevents the surface of the white rice from being scratched. Have Further, consideration is given to making the bristle of the polishing brush 7 longer and softly hitting the white rice surface so as not to excessively brush the white rice surface.

  Here, the polishing brush 7 will be described in detail. The material of the polishing brush 7 is 66 nylon (nylon is a trademark), fluorine resin, polypropylene, polybutylene terephthalate (PBT), polyphenylene sulfide (PPS), acrylic, etc. in consideration of mechanical strength and ease of manufacture. It is preferable to use the resin system. Of course, animal fibers, plant fibers, and the like may be used. Further, the wire diameter (thickness per brush) of the brush may be set to a diameter of 0.05 mm or more and 0.5 mm or less, but 0.2 mm to 0.3 mm is particularly preferable. Although it is conceivable that the length of the brush is set to 3 mm or more and 30 mm or less, about 11 mm to 13 mm is particularly preferable. Here, the wire diameter and length of the brush affect the stiffness of the brush. Further, the wire diameter of the brush affects the number of brushes per unit area and the degree of scraping of the recesses on the surface of the white rice. Further, the wire diameter and length of the brush are considered to be factors that influence the brushing (finishing) condition and the brush life.

  Next, elements that determine the polishing degree of white rice will be described. The degree of polishing of white rice can be adjusted by changing individually (a) the number of polishing brushes 7, (b) the inner diameter of the wire mesh 15, and (c) the rotational speed of the rotary shaft 2. Hereinafter, it demonstrates in order.

(A) Number of polishing brushes 7 The degree of polishing of white rice can be adjusted depending on the number of polishing brushes 7. The polishing degree of white rice is proportional to the distance passing through the polishing brush 7. If the distance is long, the degree of polishing increases, and if the distance is short, the degree of polishing decreases. In the present embodiment, the combination of the brush spiral portion 6 and the polishing brush 7 is a single polishing block, and a plurality of the polishing blocks are arranged, and the degree of polishing can be adjusted by increasing or decreasing the number of blocks. In addition, it is possible to finish washed rice according to the quality (characteristics) and taste of white rice.

  Here, a method of increasing or decreasing the number of polishing blocks will be described with reference to FIG. FIG. 8 shows a configuration example in which the number of five polishing blocks provided in FIG. 1 is reduced to three. Specifically, among the five polishing blocks in FIG. 1, the odd-numbered polishing blocks counted from the top or the bottom are left as they are, and the even-numbered polishing blocks are the fourth in which the portion of the polishing brush 7 is also a spiral portion. The block 60 corresponding to the spiral body is replaced. This spiral-only block 60 has the function of transferring the white rice upward, and has the function of polishing the white rice, like the cereal spiral portion 5, the brush spiral portion 6 and the discharge spiral portion 8 in FIG. Absent. Thus, by exchanging the polishing block with the block 60, the number of polishing brushes 7 can be reduced and the polishing degree can be lowered.

(A) Inner diameter of the metal strip 15 The degree of polishing can be adjusted by changing the inner diameter of the metal screen 15. When the clearance between the inner surface of the dehiding wire mesh 15 and the polishing brush 7 is reduced by reducing the inner diameter of the dehashing wire mesh 15, the tip of the brush material of the polishing brush 7 comes into contact with each grain of white rice without fail. Increases effectiveness. On the contrary, by increasing the inner diameter of the dehulling wire mesh 15, when white rice can easily pass through the gap between the inner surface of the dehulling wire mesh 15 and the polishing brush 7, it is possible to cereal with reduced brushing effect. Become. In the case of brewed rice that is not finished into perfect white rice by a rice mill, it is possible to remove only the floating rice cake adhering to the surface of the white rice without proceeding the accuracy of rice kneading. Moreover, the white rice remaining in the machine at the end of the operation can be easily discharged. Further, even when the brush material of the polishing brush 7 is shortened due to wear and the brushing effect is lowered, the clearance between the brush material tip and the inner diameter of the metal strip can be adjusted.

  FIG. 9 shows an example of a configuration for making the inner diameter of the metal strip 15 variable. In FIG. 9, the stripping wire net 15 has the basic structure shown in FIG. 4, and a pair of similar bent pieces 15b, 15b are further provided at positions facing the pair of bent pieces 15a, 15a. . The opposed bent pieces 15a and 15b are fastened by a pair of fastening members 28 and 28 made of bolts and nuts. Then, a pair of inner diameter variable motors 29, 29 are provided, a pair of fastening members 28, 28 are rotated by the respective rotary shafts 29a, 29a, and the respective fastening degrees are changed, whereby the inner diameter of the metal strip 15 is removed. Can be changed. That is, when tightened, the inner diameter can be narrowed by increasing the portion where the two semi-cylindrical porous members constituting the metal strip 15 overlap, and conversely the inner diameter can be increased by loosening. In this case, the inner diameter of the metal strip 15 is changed by the motor, but the fastening degree of the fastening members 28, 28 may be changed manually.

(C) Rotational speed of the rotary shaft 2 The degree of polishing can be increased or decreased by increasing or decreasing the rotational speed of the rotary shaft 2. As described above, the number of rotations of the motor 3 is arbitrarily or preset by using an inverter device that converts the frequency of the power supply of the motor 3 and a volume or select switch provided near the operation switch 25. Thus, the rotational speed of the rotary shaft 2 can be variably controlled. Increasing the rotational speed of the rotary shaft 2 increases the peripheral speed of the tip of the polishing brush 7 and increases the brushing effect. For this reason, it becomes possible to easily discharge white rice remaining in the machine at the end of the operation. Conversely, when the rotational speed of the rotating shaft 2 is lowered, the peripheral speed of the tip of the polishing brush 7 is lowered, and the brushing effect is lowered. As a result, in the case of divided rice, it is possible to remove only the floating rice cake without increasing the accuracy of rice kneading. In addition, it is possible to finish washed rice according to the quality (characteristics) and taste of white rice.

As described above in detail, the present embodiment has the following features (A) to (G).
(A) Since the brush spiral portion 6 and the polishing brush 7 are integrated as one polishing block and can be attached to and detached from the rotating shaft 2 in units of blocks, the number of polishing blocks to be mounted on the rotating shaft 2 By increasing / decreasing, the degree of polishing of white rice can be adjusted. For example, the number of polishing brushes 7 can be reduced and the degree of polishing can be reduced by exchanging the polishing block with a block 60 in which the portion of the polishing brush 7 is also a spiral portion.

  (B) Since the brush material of the polishing brush 7 is randomly densely arranged, the individual white rice grains 26 transferred on the outer periphery of the polishing brush 7 can be uniformly polished.

  (C) Since the resistor 16 that suppresses the turning of the white rice 26 is provided on the inner peripheral surface of the stripping wire mesh 15, it is suppressed by the resistor 16 that the white rice 26 rotates on the inner peripheral surface of the stripping wire mesh 15. Is done. For this reason, it is possible to prevent the white rice 26 from turning around the inner peripheral surface of the stripping wire mesh 15 and becoming less susceptible to polishing by the polishing brush 7.

  (D) Since the spacing between the brush spiral portion 6 and the polishing brush 7 and the stripping wire mesh 15 can be adjusted by changing the inside diameter of the stripping wire mesh 15, The degree of polishing can be adjusted by adjusting the degree of contact with the tip of the polishing brush 7 and adjusting the brushing effect.

  (E) After a start operation, the supply shutter 23 is closed for a certain time (t1) until the rotation of the rotary shaft 2 by the motor 3 reaches the specified rotation speed, and the supply shutter 23 is reached after the rotation speed reaches the specified rotation speed and stabilizes. 23 is controlled to open, so if the rice is accidentally opened before the start of operation and the supply shutter 23 is opened, and then this apparatus is activated, the white rice accumulated in the lower husk spiral portion 5 is rapidly It is possible to prevent a state where the cereal has been ceased and stagnated in the brush spiral portion 6 and cerealing is impossible. Further, when stopping the apparatus, the supply shutter 23 is closed immediately after the stop operation, and the apparatus is controlled to stop after a certain time (t2) until the polishing brush 7 and the brush spiral portion 6 no longer have white rice. Therefore, it is possible to prevent white rice from remaining in the cereal spiral portion 5 after the operation is stopped and mixed with different varieties white rice during the next operation, or the cereal spiral portion 5 is soiled.

  (F) The cerealing cylinder 9 and the discharge cylinder 12 have a structure in which the fixed position can be changed by ¼ rotation in a concentric state, and the hopper 10 and the product discharge cylinder correspond to the position change. 14 is configured so that the mounting position can be changed to the same position, so even if the installation location of the machine is restricted, it can be flexibly connected to other equipment (rice milling machine, etc.). At the same time, the take-out position of the white rice can be easily changed.

  (G) For example, by using an inverter device that converts the frequency of the power supply of the motor 3 and a volume or a select switch provided near the operation switch 25, the number of rotations of the motor 3 is arbitrary or set in advance. Since it can be variably controlled so as to rotate at the rotational speed, the turning speed of the polishing brush 7 can be variably controlled to easily adjust the polishing degree of the white rice.

[Second Embodiment]

In these drawings, the same or corresponding components as those in FIGS. 4 and 7 are denoted by the same reference numerals used in FIGS. 4 and 7.

  In the dry-type non-washing rice production apparatus of the present embodiment, the portions other than the dehulling wire mesh have the same configuration as that of the first embodiment and perform the same operation, and thus illustration and description of those portions are omitted.

  As shown in FIG. 10, in the present embodiment, a large number of cuts 16 a are formed at predetermined intervals in the longitudinal direction of the resistor 16 on the inner surface of the metal strip 15. The cut 16a is provided on the side where the white rice comes into contact when the polishing brush 7 rotates. For this reason, as shown in FIG. 11, when the polishing brush 7 rotates, the white rice 26 enters the cut 16a, and another white rice is arranged next to the cut 16a, so that the white rice 26 is arranged horizontally along the cut 16a as a whole. become. That is, since the direction in which the white rice 26 is lined up coincides with the rotation direction of the polishing brush, the bottom of the vertical groove line 27 of the white rice 26 is effectively brushed.

  Thus, according to this embodiment, since the notch 16a for aligning the direction of the white rice 26 is provided in the resistor 16, the direction in which the white rice 26 is lined up with the rotation direction of the polishing brush 7 is determined. It is possible to effectively brush up to the bottom of the 26 longitudinal groove lines 27. A similar effect can be obtained by providing a recess in place of the cut 16a.
