Description

  The present invention relates to a food washing apparatus used for washing (including sterilization and rinsing) foods such as vegetables, seaweed, and seafood.

  Conventionally, as a food washing apparatus, a washing tank for containing washing water has been provided, a conveyance washing path is formed inside the washing tank, a take-out conveyor is attached to the food take-out section, and the food to be washed is placed below the conveyance washing path. On the other hand, what provided the air jet pipe which bubbles a bubble is known (refer patent document 1).

  In this food cleaning apparatus, the food to be cleaned that has been input to the food input unit is sent to the food extraction unit by the water flow generated from the food input unit toward the food extraction unit. During the transfer, air bubbles blown from the air jet pipe are washed from below and washed, and the food to be washed transported to the food take-out section is taken out of the washing tank by the take-out conveyor. .

  In such a food cleaning apparatus, as a means for enhancing the cleaning effect, a method of lengthening the transport cleaning path to increase the cleaning time can be considered. However, if the transport cleaning path is lengthened, the apparatus becomes larger accordingly. However, the problem that an installation space will become large arises.

Therefore, in the present applicant, a partition plate is provided in the direction perpendicular to the transfer direction of the transport cleaning path in the middle of the transport cleaning path, and a blocking surface portion that blocks the water flow of the transport cleaning path is formed below the partition plate. In addition, a food cleaning apparatus has been proposed as a prior art in which a net portion is formed on the upper portion thereof to receive food to be cleaned while allowing floating dust or the like to pass along with the water flow ( Japanese Patent Laid-Open No. 2006-280233 ).

  Since the preceding food cleaning apparatus blocks the water flow by the blocking surface portion of the partition plate, a water flow that circulates around the front side of the partition plate is generated, and the food to be cleaned flows so as to circulate in the conveyance cleaning path. Therefore, the cleaning time can be extended, and during that time, air bubbles are continuously bathed from below and stirred, so that the cleaning effect can be improved while shortening the transport cleaning path.

However, in this prior food cleaning device, the food to be cleaned sticks to the net part due to the water flow, and especially the net part that allows the water flow to pass through the upper part of the partition plate near the water surface. The food sticks to the net part and stays there, which closes the net part, so that the floating dust cannot pass through the net part and the floating dust cannot be removed.
In addition, since the food to be cleaned remains stuck to the net part, it has not been able to sufficiently improve the cleaning effect, such as being unable to uniformly expose the air bubbles from the air ejection pipe. .
JP 2002-330743 A

  The present invention has been made to solve the above-described conventional problems, and in contrast to a food to be cleaned stuck to a mesh plate, the bubbles are raised along the mesh plate to remove the food to be cleaned. While being peeled from the plate, the food to be cleaned is evenly dispersed, which allows the suspended waste to pass through and be removed reliably, and the food to be cleaned is uniformly washed with air bubbles from the air jet tube An object of the present invention is to provide a food washing apparatus capable of sufficiently improving the effect.

In order to solve the above-mentioned problem, the food cleaning device of the present invention (Claim 1)
A cleaning tank for storing cleaning water is provided,
Inside the washing tank, a conveyance washing path is formed from a food input part on one end side provided with a washing water inlet to a food take-out part on the other end side provided with a washing water outlet, A take-out conveyor is attached to the food take-out part,
A separator plate is provided at the bottom of the transport cleaning path, and a cleaning air jet pipe is provided below the separator plate for jetting air so that a water flow is generated from the food input section to the food take-out section in the transport cleaning path. In food cleaning equipment
In the middle of the transport cleaning path, a partition plate is provided in a direction perpendicular to the transfer direction of the transport cleaning path, and the partition plate is provided to be movable up and down,
This partition plate is formed with a blocking surface portion that blocks the water flow of the transport washing path at the lower portion, and a net portion that allows floating dust and the like to pass along with the water flow while receiving the food to be cleaned at the upper portion.
A mesh plate is detachably provided holding a bubble ejection space on the front side of the partition plate,
In the lower part of the bubble ejection space, there is provided a separation air ejection pipe for ejecting air so as to raise the bubbles along the mesh plate , and the separation air ejection pipe is in a state where the partition plate is lowered. It was set as the structure formed so that the ejection of air might be stopped in the state which ejected air and the said partition plate raised .

Moreover, the food washing apparatus of the present invention (Claim 2)
It was set as the structure by which the filtration bag was attached to the back surface of the net part of the said partition plate so that attachment or detachment was possible.

In the food washing apparatus of the present invention, since the water flow is blocked by the blocking surface portion of the partition plate, a water flow is generated that circulates around the front side of the partition plate.
In addition, the food to be cleaned is received by a mesh plate provided on the front side of the partition plate. Especially, in the vicinity of the water surface, the food to be cleaned tries to stick to the mesh plate, but the air from the air blow-off pipe for peeling is used. Since the bubbles rise along the mesh plate, the food to be cleaned can be peeled off from the mesh plate by the bubbles.
In addition, some of the bubbles rising along the mesh plate flow into the front side from the rear surface of the mesh plate, so that the food to be cleaned peeled off from the mesh plate can be dispersed.

  In this way, the food to be cleaned flows through the barrier cleaning surface of the partition plate so that it circulates in the transport cleaning path, so that the cleaning time can be increased while the apparatus is formed into a compact. Since the bubbles from the tube are bathed and stirred, the cleaning effect can be improved.

In particular, in the present invention, the food to be cleaned is received by the mesh plate provided on the front side of the partition plate, and the food to be cleaned stuck to the mesh plate is removed from the peeling air jet pipe. It can be peeled off by air bubbles. Accordingly, the floating dust can pass through the net portion of the net plate and the partition plate together with the water flow near the water surface, and the floating dust can be reliably removed.
In this case, if a filtration bag is attached to the back surface of the mesh portion of the partition plate (claim 2), the floating dust can be collected and removed by this filtration bag.

  In addition, since the food to be cleaned can be dispersed by the air bubbles from the peeling air jet tube, the air bubbles from the air jet tube for cleaning can be uniformly exposed to the food to be cleaned, and the cleaning effect is sufficiently improved. Can be made.

  Further, when the partition plate is raised, it is formed so as to stop the ejection of air by the peeling air ejection pipe. Therefore, when the blockage by the partition plate is released, the food to be cleaned is transferred toward the food take-out section, and at this time, since the ejection of air from the peeling air ejection pipe is stopped, the transfer is braked by bubbles. You wo n’t be charged. Thereby, the to-be-cleaned food can be quickly transferred and discharged.

  1 and 2 are cross-sectional views of a food washing apparatus according to an embodiment of the present invention. FIG. 1 is a view of a state in which a partition plate is lowered into a cleaning tank, and FIG. It is a figure of the state raised outside. FIG. 3 is a front view of the partition plate.

The food washing apparatus 1 is provided with a washing tank 2 for containing washing water.
In the washing tank 2, a transport cleaning path 3 is formed from the food input part 31 on one end side to the food takeout part 32 on the other end side, and the takeout conveyor 4 is attached to the food takeout part 32.

  The washing water vigorously flows into the washing tank 2 from the inlet 21 formed on the food input side of the washing tank 2, and flows out from the outlet 22 formed on the food extraction side of the washing tank 2. After the dust contained in the washing water is removed, the circulation system returns from the inlet 21 to the washing tank 2 again by a pump (not shown).

  A separator plate 5 is provided at the lower part of the transport washing path 3, and air is jetted below the separator plate 5 so that the food to be cleaned A moving through the transport cleaning path 3 is exposed to bubbles from below. A cleaning air jet pipe 6 (hereinafter referred to as “cleaning jet pipe”) is provided.

The cleaning jet pipe 6 is provided so as to extend in the transport direction of the transport cleaning path 3, and is inclined from the food input unit 31 to the food output unit 32 by being inclined on the upper surface thereof toward the food output unit 32. Several nozzle pipes 61 for ejecting air are projected so as to generate a water flow toward the front, and the tip of the nozzle pipe 61 faces the transport washing path 3 from the hole 50 provided in the separator plate 5. Is formed.
The cleaning jet pipe 6 is connected to a blower (not shown) as an air supply device via an air pipe.

  Further, a partition plate 7 is provided in the direction perpendicular to the transfer direction of the transport cleaning path 3 in the middle of the transport cleaning path 3 (in the embodiment, a portion before the take-out conveyor 4).

The upper part of the partition plate 7 is formed in a net part 70 through which the water flow in the transport cleaning path 3 flows, and the lower part is formed in a blocking surface part 71 that blocks the water flow in the transport cleaning path 3.
And it was pulled up so that it may be located in the descent position (position shown in Drawing 1) where it was submerged in washing water so that the water surface W of washing water may be located in the above-mentioned net part 70, and above the water surface W of washing water It is provided so that it can be raised and lowered between the raised positions (positions shown in FIG. 2).
A filtration bag 72 is detachably attached to the back surface of the mesh portion of the partition plate 7.

The partition plate 7 is moved up and down by a lift drive device 8. The lift drive device 8 pivotally supports the upper end portion of the partition plate 7, and an air cylinder 83 is attached to an arm member 82 provided on the pivot support portion 81. The partition plate 7 is lifted and lowered by expansion and contraction of the air cylinder 83.
In this way, when the partition plate 7 is driven by the lifting drive device 8, the work can be easily performed without requiring labor to lift and lower the partition plate 7.

A net plate 76 is provided on the front side of the partition plate 7 to hold the bubble ejection space 75.
As shown in FIG. 3, the mesh plate 76 has a frame 76 a provided around the inside by a mesh 76 b, and both ends of the mesh plate 76 are provided in guides 7 a and 7 a provided at both ends of the partition plate 7. It is detachably attached to the partition plate 7 by being slidably fitted. In the figure, 76c is a handle.
As described above, when the mesh plate 76 is made detachable, if several types of mesh plates corresponding to the type and size of the food to be cleaned A are prepared, an optimal mesh screen is selected from these. can do.
In addition, when the partition plate 7 is lowered, the lower end of the mesh plate 76 is brought into contact with the stopper plate 25 to prevent the water flow from leaking from under the mesh plate 76.

  The mesh portion 70 and the mesh plate 76 of the partition plate 7 can be formed in an appropriate structure that allows passage of water flow, such as forming a punching hole in the plate material, in addition to attaching a metal mesh, and the mesh of the metal mesh, the punching hole The pore diameter, density, etc. are appropriately determined according to the type and size of the food to be cleaned.

In the lower part of the bubble ejection space 75 in a state where the partition plate 7 is lowered, a separation air ejection tube 9 (hereinafter referred to as “a separation ejection tube”) that ejects air so as to raise the bubbles along the mesh plate 76. ") Is piped in a direction perpendicular to the transfer direction.
In this case, a large number of ejection holes 90 are formed at regular intervals on the upper surface of the peeling ejection pipe 9, and bubbles are generated by the air ejected from the ejection holes 90.
Further, as an air supply device for the peeling jet pipe 9, a blower (not shown) used for the cleaning jet pipe 6 is shared.

The timing of jetting air from the stripping jet pipe 9 is linked to the raising / lowering timing of the partition plate 7.
That is, in the state where the partition plate 7 is lowered (the state shown in FIG. 1), air is ejected by the peeling jet tube 9, while in the state where the partition plate 7 is raised (the state shown in FIG. 2), the peeling jet tube 9 is ejected. It is formed so as to stop the ejection of air.
In this case, the expansion / contraction operation of the air cylinder 83 for raising and lowering the partition plate 7 is performed by opening / closing an electromagnetic valve (not shown), and the air blowing / stopping by the peeling jet tube 9 is performed by opening / closing a ball valve (not shown). It is formed to do.

A timer (not shown) is provided for opening / closing control of the electromagnetic valve and the ball valve.
For example, by opening the electromagnetic valve and opening the ball valve, the partition plate 7 is sunk to the lowered position for a certain period of time (for example, 40 seconds), and air is ejected from the peeling ejection pipe 9, and then the electromagnetic valve is closed. The operation of pulling up the partition plate 7 to the raised position by closing the ball valve for a certain time (for example, 30 seconds) and stopping the ejection of air from the peeling ejection pipe 9 is defined as one cycle, and this cycle is repeated. The timer is controlled.
In this way, when the raising / lowering timing of the partition plate 7 and the air ejection timing by the separation ejection pipe 9 are controlled by the timer, time management becomes unnecessary, and automatic operation by unmanned operation becomes possible.

In the food washing apparatus 1 of the present invention, the food is taken out from the food input section 31 to the transport washing path 3 by the momentum of the washing water flowing into the washing tank 2 from the inlet 21 and the momentum of the air ejected from the washing ejection pipe 6. A water flow can be generated toward the portion 32.
Therefore, when the food A to be cleaned is introduced into the food input unit 31, the food A to be cleaned is washed by blowing air bubbles from below, and the conveyance cleaning path 3 is moved to the food take-out unit 32 by a water stream while repeatedly floating and sinking. It is transported towards.

  At this time, the partition plate 7 is lowered to the lowered position by the lifting and lowering driving device 8 and is submerged in the transport cleaning path 3. Since the water flow is blocked by the blocking surface portion 71 of the partition plate 7, Circulating water flows around the front side.

  Thus, since the to-be-cleaned food A flows so that it may circulate in the conveyance washing path 3 by the interruption | blocking surface part 71 of the partition plate 7, it can take long washing | cleaning time, forming an apparatus in a compact, Since the bubbles from the cleaning jet pipe 6 are bathed and stirred, the cleaning effect can be improved.

In addition, the food A to be cleaned is received by the mesh plate 76 provided on the front side of the partition plate 7 and tries to stick to the mesh plate 76, but the bubbles from the exfoliating jet tube 9 are along the mesh plate 76. As a result, the to-be-cleaned food A can be peeled off from the mesh plate 76 by the bubbles.
Thereby, floating dust can pass through the net plate 76 and the net portion 70 of the partition plate 7 together with the water flow near the water surface, and the floating dust can be reliably removed.
In addition, when the filtration bag 72 is attached to the back surface of the mesh unit 70, the floating dust that has passed through the mesh unit 70 can be collected and removed by the filtration bag 72.

In addition, since some of the bubbles rising along the mesh plate 76 flow from the back surface of the mesh plate 76 to the front side, the food to be cleaned A peeled off from the mesh plate 76 can be dispersed.
Thereby, the air bubbles from the cleaning jet pipe 6 can be uniformly exposed to the food A to be cleaned, and the cleaning effect can be sufficiently improved.

Then, after a certain period of time has elapsed, the air cylinder 83 of the elevating drive device 8 is operated by timer control, and the partition plate 7 is pulled up from the lowered position to the raised position, and at the same time, air is ejected from the peeling ejection pipe 9. Is stopped.
Thereby, since the blockade by the partition plate 7 is released, the food A to be cleaned is transferred toward the food take-out section 32, and then the food A to be cleaned is scooped up by the take-out conveyor 4 at the food take-out section 32. It is transported on the take-out conveyor 4 and taken out of the cleaning tank 2.

At this time, the ejection of the air from the exfoliating ejection pipe 9 was stopped because, if the air was kept being ejected, the bubbles were bathed in the food to be cleaned A being transported, so the transfer was braked. It becomes a state. As a result, it takes time to discharge the food to be cleaned A, and the quality may vary or be damaged.
Therefore, while raising the partition plate 7 and transferring the food A to be cleaned, the bubbles generated from the peeling jet tube 9 are stopped, whereby the food A to be cleaned can be transferred quickly. Can be discharged.

  As described above, when a predetermined time elapses after the partition plate 7 is pulled up to the raised position, the air cylinder 83 is operated by timer control so that the partition plate 7 is submerged from the raised position to the lowered position, and for peeling. Air is supplied to the ejection tube 9 and bubbles are ejected. Thereafter, the same operation is repeated and washing is performed automatically and continuously.

  In addition, the food washing apparatus of this invention can also use this with 1 unit | set, for example, arrange | positions 2 units | sets of food washing | cleaning apparatus, puts sterilization water as washing water in the 1st unit, and sets 2 units | sets. Rinsing water is put into the eyes, and the use form is arbitrary, such as washing by a method of sequentially passing the food to be washed through these apparatuses.

  In addition, the actuator for the lift drive device for the partition plate is not limited to the air cylinder drive, but may be a feed screw drive or chain drive using an electric motor, or a manual operation without using the lift drive device.
