Description

  The present invention relates to an apparatus for removing a shell part of a sprout vegetable that removes small pieces including the shell part from the sprout vegetable.

  Harvested sprouts, such as bean sprouts, contain unwanted items that are small pieces such as shells of raw material beans. As techniques for removing these unnecessary materials from the harvested bean sprouts, there are first and second conventional techniques described later.

  As a first conventional technique, Patent Literature 1 discloses a bean sprout purification apparatus. The bean sprout refiner, which is a device for removing the sprouts of sprout vegetables, vibrates the vibrating frame that supports the endless belt tilted upward in the moving direction, the drive device that runs the endless belt in the moving direction, and the vibrating frame And a scraper that is disposed to face the endless belt and removes deposits on the endless belt.

  The bean sprouts supplied on the endless belt drop downward along the inclination on the endless belt that is vibrating from the vibration frame. The unwanted matter adhering to or mixed with the bean sprout gradually settles down due to the vibration of the endless belt, adheres to the upper surface of the endless belt, and is transferred upward as the endless belt moves. Unnecessary items carried upward together with the endless belt are removed from the endless belt by the scraper and discharged.

  A bean sprout refining device as a second prior art includes a mounting portion in which a passage hole through which an unnecessary substance can pass is formed so as to penetrate vertically, and a mounting surface on which a bean sprout is mounted is formed, A vibration applying unit that vibrates the mounting unit in a direction intersecting the mounting surface, and a liquid discharge unit that discharges liquid from above to the mounting unit.

  Since the mounting portion is vibrated in a direction intersecting the mounting surface by the vibration applying means, the bean that is mounted on the mounting surface receives an impact force from the mounting surface, thereby Unnecessary items are removed from the bean sprouts. Further, since the liquid is discharged from above onto the mounting portion by the liquid discharge means, the unnecessary matter that has been detached as described above passes through the passage hole together with the discharged liquid and flows out of the mounting portion. To do. Therefore, it is possible to efficiently remove unwanted materials from the bean sprouts.

JP-A-8-131145

  In the first prior art, the unwanted matter that has detached from the sprouts adheres to the upper surface of the endless belt and is transferred upward along with the movement of the endless belt. In the middle of this transfer, a part of the unwanted matter adhering to the upper surface of the endless belt is detached from the upper surface of the endless belt by the vibration of the endless belt. In this way, a part of the unwanted matter detached from the upper surface of the endless belt adheres again to the bean sprout, and falls down on the endless belt along the inclination along with the bean sprout. Therefore, there is a problem in that unnecessary materials cannot be efficiently removed.

  In the second prior art, unnecessary substances can be efficiently removed from bean sprouts, but there is a problem that a large amount of water is required to achieve such an effect.

  The objective of this invention is providing the shell part removal apparatus of the sprout vegetable which can remove efficiently the small piece containing the shell part from a sprout vegetable, and can suppress consumption of a liquid.

The present invention includes a mounting portion on which a plurality of small piece passage holes through which small pieces including a shell portion of a shoot vegetable can pass are formed so as to penetrate vertically, and a mounting surface on which the shoot vegetable is mounted is formed. ,

  Further, according to the present invention, a retraction surface that retreats downward from the mounting surface and faces upward through an opening of the small piece passage hole in the placement surface is provided in the plurality of small piece passage holes. It is characterized by being formed respectively.

The present invention also includes a storage tank in which liquid is stored,
Fluidization means for fluidizing the liquid stored in the storage tank,
A liquid overflowing from the storage tank flows into the mounting portion.

Further, in the present invention, the fluidizing means jets liquid in the storage tank, fluidizes the liquid stored in the storage tank,
The liquid supply means also supplies the liquid recovered by the liquid recovery means to the fluidizing means.

  Further, the present invention is characterized in that the mounting portion has a liquid removal portion that is disposed at a position where the liquid overflowing from the storage tank flows and removes the liquid from the inflow containing the liquid.

  In addition, the present invention further includes another liquid discharge means for supplying a liquid different from the liquid recovered by the liquid recovery means from the outside and discharging the liquid supplied from the outside to the mounting portion from above. It is characterized by.

Further, in the present invention, the vibration applying means vibrates the mounting portion so that the sown vegetable mounted on the mounting surface moves in a predetermined movement direction on the mounting surface,
The other liquid ejecting means is provided downstream of the liquid ejecting means in the moving direction.

Further, in the present invention, the liquid recovery means includes a solid removal unit that removes solids including the small pieces from the effluent flowing out from the mounting unit.
The solid removal unit is provided along an inclined surface that is inclined with respect to a horizontal plane, and a plurality of liquid passage holes through which liquid can pass are formed so as to penetrate vertically, and the effluent is supplied from above. It is characterized by that.

  According to the present invention, a plurality of small piece passage holes through which small pieces including a shell portion of the sprout vegetable can pass are formed in the mounting portion so as to penetrate vertically. In addition, the mounting surface is formed with a mounting surface on which the sprout vegetables are mounted.

  The mounting portion is vibrated in a direction intersecting the mounting surface by vibration applying means. Thus, since the said mounting part is vibrated, the sprout vegetable mounted on the said mounting surface receives impact force from the said mounting surface, and, thereby, the small piece containing the shell part remove | deviates from a sprout vegetable. . Further, the liquid is discharged from above onto the mounting portion by the liquid discharge means. Thus, since the liquid is discharged to the mounting part, the small piece including the shell part of the sprouted vegetable separated as described above passes through the small piece passage hole together with the discharged liquid, and the mounting part Spill from. Therefore, the small piece containing the shell part can be efficiently removed from the sprout vegetable.

  Moreover, the liquid flowing out from the mounting portion is recovered by the liquid recovery means and supplied to the liquid discharge means by the liquid supply means. Since the liquid flowing out from the mounting portion is used again in this way, even if the amount of liquid ejected from the liquid ejecting means is increased in order to improve the efficiency related to the removal of the small pieces, the liquid consumption Can be suppressed.

  Further, according to the present invention, a retraction surface is formed on each of the mounting portions with respect to the plurality of small piece passage holes. The retracting surface is retracted downward from the mounting surface and faces upward through an opening of the small piece passage hole in the mounting surface. Such a retreating surface can receive an entering object that has entered the small piece passage hole. The sprout vegetable has a substantial part including a stem and a shell including a seed coat. As the entering material, a substantial part of the shoot vegetable enters the small piece passage hole, and a small piece including the shell of the shoot vegetable enters.

  The approaching object received by the retracting surface is splashed upward with respect to the retracting surface by the upward movement of the vibration of the mounting portion. Since the small piece has a mass smaller than that of the substantial part of the sprout vegetable, the small piece is pushed away by the liquid discharged from the liquid discharge means, passes through the small piece passage hole, and flows out of the mounting portion. On the other hand, since the substantial part of the sprout vegetable has a larger mass than the small piece, the substantial part of the sprout vegetable is not swept away by the liquid ejected from the liquid ejecting means, and is passed through the small piece passage hole. Escape on the surface. As a result, it is possible to prevent even the substantial part of the sprout vegetable from passing through the small piece passage hole and flowing out of the mounting part.

  According to the present invention, liquid is stored in the storage tank. The liquid stored in the storage tank is fluidized by fluidizing means. When the sprouts are put into such a storage tank, the sprouts are put in the storage tank, thereby weakening the connection between the substantial part and the shell part.

  Liquid that overflows from the storage tank flows into the mounting section. At this time, the sprouting vegetable overflows from the storage tank and flows into the mounting part together with the liquid, whereby the sprouting vegetable is mounted on the mounting surface. Thus, since the connection between the substantial part and the shell part is weakened in the sprout vegetable mounted on the mounting surface, the shell part is easily detached from the sprout vegetable. The shell can be removed more efficiently.

  Since the sprout vegetables flow into the mounting part from the storage tank together with the liquid overflowing from the storage tank, it is not necessary to separately provide means for transferring the sprout vegetables from the storage tank to the mounting part. . Therefore, it is possible to simplify the configuration and save space.

  Moreover, according to this invention, the said fluidization means can inject the liquid in the said storage tank, and can fluidize the liquid stored by the said storage tank by this. The fluid recovered by the liquid recovery means is also supplied to the fluidizing means by the liquid supply means. In this way, the liquid flowing out of the mounting portion is used again, so that the consumption of the liquid can also be suppressed.

  According to the invention, the mounting portion has a liquid removal portion. The liquid removing portion is disposed at a position where the liquid overflowing from the storage tank flows in, and removes the liquid from the inflow containing the liquid. Since the liquid is removed from the inflow containing the liquid by the liquid removing portion, the amount of the liquid flowing into the main body portion of the mounting portion where the plurality of small piece passage holes are formed is reduced. Can do.

  When the amount of the liquid flowing into the main body portion is large, even the substantial part of the sprout vegetable is pushed away by the liquid and passes through the small piece passage hole. In consideration of this point, as described above, the amount of the liquid flowing into the main body portion is reduced, so that even the substantial part of the sprouting vegetable passes through the small piece passage hole and from the mounting portion. It can be prevented from leaking.

  According to the invention, the other liquid discharge means is supplied with a liquid different from the liquid recovered by the liquid recovery means from the outside, and discharges the liquid supplied from the outside to the mounting portion from above. . Accordingly, the liquid can be replenished from the outside, and the small piece can be pushed out by the liquid ejected from the other liquid ejecting means, and the small piece can flow out of the mounting portion through the small piece passage hole.

  Further, according to the present invention, the vibration applying means vibrates the mounting portion, and thereby the sprout vegetable mounted on the mounting surface moves in a predetermined moving direction on the mounting surface. In this case, as the downstream side in the moving direction becomes, the removal rate of the shell part of the sprout vegetable increases, and therefore, on the downstream side in the moving direction, the sprout vegetable from which the shell part has been removed is taken out from the mounting part. Can do.

  The other liquid ejecting means is provided downstream of the liquid ejecting means in the moving direction. As described above, the other liquid discharge means discharges the liquid different from the liquid recovered by the liquid recovery means from above onto the mounting portion. Therefore, the sprout vegetables from which the shell part has been removed can be washed before taking out from the mounting part.

  According to the invention, the liquid recovery means has a solid removal unit. The solid removal unit is formed with a plurality of liquid passage holes through which liquid can pass vertically, and the effluent is supplied from above. Of the effluent supplied from above, the liquid passes through the plurality of liquid passage holes, but the solid including the small pieces cannot pass through the plurality of liquid passage holes. Therefore, the solid can be recovered by removing the solid from the effluent flowing out from the mounting portion by the solid removing portion.

  The solid removal unit is provided along an inclined surface that is inclined with respect to a horizontal plane. Thus, since the said solid removal part is provided, the said solid of the said effluent flows below on the said solid removal part along the said inclined surface, and is discharged | emitted from the said solid removal part. Therefore, accumulation of the solid on the solid removal portion is prevented. This eliminates the need to remove the accumulated solid from the solid removal section.

  FIG. 1 is a front view showing the configuration of a sprout vegetable shell removing apparatus 1 according to an embodiment of the present invention. FIG. 2 is a plan view of the shell removing device 1 as viewed from above in FIG. Sprout vegetables are those obtained by germinating legume seeds such as black mappe, mung beans, and soybeans in water without light. The sprout vegetable has a substantial part including a stem and a shell including a seed coat. Some of the newly grown vegetables include a cotyledon in addition to the stem as a substantial part, and an example of such a newly grown vegetable is so-called “soy bean sprouts” in which soybeans are germinated.

  The shell removing device 1 is used to remove small pieces including the shell from the sprouts, and in particular, a sprout vegetable including stems and cotyledons as a substantial part, for example, a small piece including the shell from soybean sprouts. It is preferably used for removing. In addition to the husks of the sprout vegetables, the small pieces include strawberries and fine roots, and also include ungerminated seeds.

  The shell removing device 1 is formed with a plurality of small piece passage holes 3 vertically passing through which small pieces including a shell portion of a sprout vegetable can pass, and a mounting surface 4 on which the sprout vegetable is placed is formed. A mounting portion 5, vibration applying means 6 that vibrates the mounting portion 5 in a predetermined vibration direction A that intersects the mounting surface 4, and liquid is applied to the mounting portion 5 from above. And liquid discharge means 7 for discharging in a dispersed manner. The shell removing device 1 further includes a storage tank 8 in which the liquid is stored, and a fluidizing means 9 for injecting the liquid in the storage tank 8 to fluidize the liquid stored in the storage tank 8. The liquid overflowing from the storage tank 8 flows into the mounting portion 5. Further, the shell removing device 1 supplies the liquid recovery means 10 for recovering the liquid flowing out from the mounting section 5, the liquid recovered by the liquid recovery means 10 to the liquid discharge means 7 and the fluidization. Liquid supply means 11 for supplying also to the means 9 is further provided. Further, the shell removing device 1 supplies a liquid different from the liquid recovered by the liquid recovery means 10 from the external liquid source 13, and supplies the liquid supplied from the external liquid source 13 to the mounting unit 5. Another liquid discharge means 12 that discharges from above is further provided.

  In such a shell part removal apparatus 1, the sprouts are put into the storage tank 8. Liquid is stored in the storage tank 8, and the liquid stored in the storage tank 8 is fluidized by the fluidizing means 9. When a sprout vegetable is thrown into such a storage tank 8, the input sprout vegetable will be stirred in the storage tank 8, and this will weaken the connection between a substantial part and a shell part.

  After the sprout vegetable thrown into the storage tank 8 is stirred in the storage tank 8, it flows into the mounting part 5 with the liquid overflowing from the storage tank 8, and is mounted on the mounting surface 4. FIG. Thus, since the connection between the substantial part and the shell part is weakened in the shoot vegetable mounted on the mounting surface 4, the shell part is easily detached from the shoot vegetable. The shell can be removed more efficiently.

  Moreover, since the sprout vegetable thrown into the storage tank 8 flows into the mounting part 5 from the storage tank 8 with the liquid overflowing from the storage tank 8, it is for transferring a sprout vegetable from the storage tank 8 to the mounting part 5. There is no need to provide a separate means. Therefore, it is possible to simplify the configuration and save space.

  Since the mounting portion 5 is vibrated in the vibration direction A intersecting the mounting surface 4 by the vibration applying means 6, the sprouting vegetables mounted on the mounting surface 4 are impacted from the mounting surface 4. Under the force, the shell is detached from the sprout vegetable. Further, since the liquid is dispersed and discharged from above by the liquid discharge means 7, the small piece including the shell part of the sprout vegetable that has been detached as described above passes along the discharged liquid to the mounting portion 5. It passes through the hole 3 and flows out from the mounting portion 5. Therefore, the small piece containing the shell part can be efficiently removed from the sprout vegetable.

  The liquid flowing out from the mounting portion 5 is recovered by the liquid recovery means 10 and supplied to the liquid discharge means 7 and the fluidization means 9 by the liquid supply means 11. Since the liquid flowing out from the mounting portion 5 is used again in this way, even if the amount of liquid discharged from the liquid discharge means 7 is increased in order to improve the efficiency related to the removal of the small pieces, Consumption can be suppressed.

  The other liquid ejection means 12 is supplied with a clean liquid different from the liquid recovered by the liquid recovery means 10 from the external liquid source 13, and supplies the liquid supplied from the external liquid source 13 to the mounting unit 5. Dispersed from above and discharged. Accordingly, the liquid can be replenished from the outside, and the small piece can be pushed out by the liquid ejected from the other liquid ejecting means 12, and the small piece can flow out of the mounting portion 5 through the small piece passage hole 3.

  The liquid used in the shell removing device 1 may be water, or cleaning water in which a chemical solution such as a detergent is mixed in water. Furthermore, the liquid may be hot water for boiling the shoot vegetables, or cold water for cooling the shoot vegetables.

  FIG. 3 is a side view of the shell removing device 1 as viewed from the left side of FIG. FIG. 4 is a side view of the shell removing device 1 as seen from the right side of FIG. Referring also to FIGS. 1 and 2, shell removing apparatus 1 is installed on horizontal floor 2.

  The mounting portion 5 extends horizontally or substantially horizontally with the base 15 supported by the floor 2 and has a substantially U-shaped cross section perpendicular to the extending direction. The mounting portion main body 16 that is exposed and opened, and a support body 17 that is fixed to the base 15 and supports the mounting portion main body 16. The base 15, the riding section main body 16 and the support body 17 are made of a metal having high corrosion resistance, such as stainless steel.

  The mounting portion main body 16 is generally formed in a plate shape extending in the extending direction, and rises upward from both sides in the width direction of the bottom portion 18 provided horizontally or substantially horizontally. It has a pair of side walls 19a, 19b extending in the extending direction, and a plurality of bar-shaped side wall connecting portions 20 that connect the upper portions of the side walls 19a, 19b at a plurality of locations in the extending direction. In FIG. 2, in order to avoid complication, each side wall connection part 20 is abbreviate | omitted.

  The bottom portion 18 has first to third riding portions 21 to 23 from one end portion to the other end portion in the extending direction, and over the first to third riding portions 21 to 23, A mounting surface 4 is formed. The first and second riding portions 21 and 22 are uniform in the width direction in the extending direction, and as the third riding portion 23 moves away from the second riding portion 22, the width is increased. Both side portions in the direction are close to each other, and the dimension in the width direction is reduced. A plurality of projecting portions 24 that protrude upward from the mounting surface 4 and extend in the extending direction are formed on the second and third mounting portions 22 and 23 at intervals in the width direction. . In the second and third mounting portions 22 and 23, the mounting surface 4 is partitioned by the respective protrusions 24, whereby the mounting surfaces 4 in the second and third mounting portions 22 and 23 are A plurality of paths extending in the extending direction are formed.

  The plurality of small piece passage holes 3 are formed over the entire second mounting portion 22 which is a main body portion. In each path in the second riding portion 22, the small piece passage holes 3 are arranged in the extending direction. Specifically, in each path in the second riding portion 22, two small piece passage holes 3 arranged in the width direction and one small piece passage hole 3 located in the center between the two small piece passage holes 3 in the width direction. Are alternately arranged in the extending direction.

  The first mounting portion 21 which is a liquid removing portion is disposed at a position where the liquid overflowing from the storage tank 8 flows. The first mounting portion 21 causes the liquid to flow out downward from the inflow including liquid overflowing from the storage tank 8, thereby removing the liquid from the inflow. Therefore, the amount of the liquid flowing into the second riding portion 22 can be reduced.

  When the amount of the liquid flowing into the second mounting portion 22 is large, even the substantial part of the sprouting vegetables is pushed away by the liquid and passes through the small piece passage hole 3 formed in the second mounting portion 22. End up. In consideration of this point, as described above, the amount of the liquid flowing into the second mounting portion 22 is reduced, so that even the substantial part of the sprouting vegetables passes through the small piece passage hole 3 and rides. It can prevent flowing out of the mounting part 5.

  Each side wall 19a, 19b has first and second side wall portions 25, 26 from one end in the extending direction toward the other end. The first side wall portions 25 of the side walls 19a and 19b are arranged in parallel to each other, and their lower ends are connected to the first and second riding portions 21 and 22 of the bottom portion 18, respectively. The second side wall portion 26 of each side wall 19a, 19b is inclined in a direction approaching each other as it is separated from the first side wall portion 25 of each side wall 19a, 19b, and the lower end portion thereof is the third riding of the bottom portion 18.

A plurality of lower connecting portions that are connected at a plurality of locations in the extending direction and are fixed to the lower surface of the second riding portion 22; In FIG. 2, in order to avoid complication, each upper connection part 28 is abbreviate | omitted.

  The vibration applying means 6 moves the mounting portion main body 16 of the mounting portion 5 so that the sprout vegetables mounted on the mounting surface 4 move on the mounting surface 4 in a predetermined movement direction B. Vibrate. The moving direction B is a direction from one end portion in the extending direction of the riding section main body 16 toward the other end portion. In this case, as the downstream side of the moving direction B is reached, the removal rate of the shell portion of the sprouts is increased. Therefore, on the downstream side of the moving direction B, the sprouted vegetable from which the shell portion has been removed is placed on the mounting portion 5. Can be taken from.

The vibration direction A of the mounting portion main body 16 by the vibration applying means 6 is inclined to the downstream side of the moving direction B as it goes upward in a virtual plane perpendicular to the width direction of the bottom portion 18 of the mounting portion main body 16. Then, a predetermined angle θ <b> 1 is formed with respect to the mounting surface 4. The predetermined angle θ1 is selected, for example, from 15 ° to 45 °, preferably 30 °. Such an angle θ1 is appropriately selected according to the kind of the sprout vegetable and further according to the amount of liquid from the liquid discharge means 7 and the other liquid discharge means 12.

  The sprout vegetables mounted on the mounting surface 4 are flipped up in the moving direction B with respect to the mounting surface 4 by the upward movement of the vibration of the mounting portion main body 16. After the upward movement, the riding section main body 16 is displaced downward and in the direction opposite to the movement direction B by the downward movement. Therefore, the sprout vegetable bounced up with respect to the mounting surface 4 falls to the downstream side in the moving direction B from the bounced-up position. By repeating this, the sprout vegetable mounted on the mounting surface 4 moves in the moving direction B.

  Specifically, the vibration applying means 6 is realized by a pair of vibration motors 30a and 30b. The vibration motors 30a and 30b are connected to the opposite fixing portions 27a and 27b of the support 17 so as to face each other from the outside. The vibration motors 30 a and 30 b are arranged at the same position with respect to the extending direction of the riding section main body 16. Each of the vibration motors 30 a and 30 b vibrates the mounting portion main body 16 in the vibration direction A via the support body 17.

  Each vibration motor 30a, 30b has an AC motor with an output shaft protruding from both sides thereof, and a pair of eccentric weights attached to both ends of the output shaft of the AC motor. The axis L of the output shaft in the AC motors of the vibration motors 30a and 30b is perpendicular to the width direction of the bottom portion 18 of the riding section main body 16, and is inclined to the upstream side in the moving direction B as it goes upward. A predetermined angle θ <b> 2 is formed with respect to the mounting surface 4. The predetermined angle θ2 is selected as 90 ° −θ1.

  In each of the vibration motors 30a and 30b, the AC motors rotate in the opposite directions at the same rotational speed, and the eccentric weights are close to each other at the same time and are separated from each other at the same time. As a result, among the forces generated by the rotation of the vibration motors 30a and 30b, the components in the width direction of the bottom portion 18 of the riding section main body 16 cancel each other, and the components in the vibration direction A strengthen each other. Therefore, it is possible to prevent vibration in the direction different from the vibration direction A of the mounting portion main body 16, and thereby the movement direction B of the sprouting vegetables placed on the mounting surface 4 of the mounting portion main body 16. Can prevent movement in different directions.

  The liquid ejecting means 7 is a plurality of nozzles for ejecting and ejecting liquid from above near the first mounting portion 21 of the second mounting portion 22 in the bottom portion 18 of the mounting portion main body 16 of the mounting portion 5.

The liquid discharged from each nozzle member 31 spreads in the width direction of the bottom portion 18 of the mounting portion main body 16 and falls on each path of the second mounting portion 22 as it goes downward. In FIG. 1 and FIG. 2, each nozzle member 31 is omitted in order to avoid complication.

If the discharge amount of the liquid from each nozzle member 31 is too small, the small pieces cannot flow out of the mounting portion 5, and if too large, even the substantial part of the sprout vegetables flows out of the mounting portion 5. End up. In consideration of this point, the discharge amount of the liquid from each nozzle member 31 can allow the small pieces to flow out of the mounting unit 5 without causing the substantial part of the sprout vegetables to flow out of the mounting unit 5. Is appropriately selected. From each nozzle member 31, for example, a liquid of 100 liters / min to 200 liters / min is discharged per m ² . The liquid ejection means 7 may be configured to be able to adjust the liquid ejection amount from each nozzle member 31.
