The food cleaning apparatus A of the present invention includes a water tank 1 for containing cleaning water, water flow generating means 2 and 3 for generating a water flow in the water tank 1 and transferring an object to be cleaned put in the water tank in a certain direction, and the water tank 1. The cleaning water spraying means 4 for spraying a water stream onto the cleaning target transported to clean the cleaning target, and the cleaning target jetted to one side of the water tank by receiving the sprayed water from the cleaning water spraying unit. An oscillating means 5 for pushing back against the jet water flow, an overflow filtration tank 6 for storing overflow drainage of washing water, and an underwater filtration tank 7 for sucking and draining foreign matters and vegetable debris floating in the washing water together with water. The main part is a control unit 8 that controls the operation of the entire apparatus.

The water tank 1 is a rectangular parallelepiped water storage container having an open top surface, which stores cleaning water therein, has an inlet 10 for foodstuffs to be cleaned at one end, and an outlet 11 for the cleaning target at the other end. Equipped with.
The object to be cleaned such as cabbage that has been charged from the charging port 10 flows through the water tank from upstream to downstream to be cleaned, and is discharged from the discharging conveyor 12 of the discharge port 11.

A jet port 2 is arranged at the upstream end of the water tank 1, and a water flow is jetted downstream from the jet port 2 to generate a water flow for transferring the object to be cleaned put into the water tank. The injection port 2 is arranged above the partition 29.
Further, an aeration nozzle 3 is arranged at the bottom of the water tank, and air is jetted from the aeration nozzle 3 toward the downstream side to generate a water flow for transferring the object to be cleaned introduced into the water tank to the downstream side.
The jet port 2 and the aeration nozzle 3 constitute a water flow generating means.

A washing water jet nozzle 4 (washing water jetting means) is provided on the right side surface of the water tank, which extends from the upstream side to the downstream side, of jetting a water flow to the object to be cleaned transferred in the water tank.
The cleaning water injection nozzle 4 has a plurality of nozzles projecting horizontally in a row at a predetermined interval above the side surface of the water tank. The cleaning water is sprayed vertically or at an angle to the object to be cleaned (foodstuff) transferred in the water tank.

Swinging means 5 is provided on the side surface of the wash water injection nozzle 4 facing the water tank.
The swinging means 5 has a function of pushing back the object to be washed, which receives the jet water of the washing water jet nozzle 4 and is swept to one side of the water tank, against the jet water flow and returns the wire net 13 (mesh). And a mounting frame 14 for fixing the wire net 13, and a drive unit 15 for swinging the mounting frame 14 back and forth.
The wire net 13 is, for example, in the shape of a horizontally long rectangle having a length of several tens of centimeters and a width slightly higher than the depth of the water tank, and the wire net 13 is arranged above the partition 29 at the bottom of the water tank 1 and has an upper side. The edge is exposed from the water surface. The mesh of the wire net 13 is formed to have a size and a shape that does not allow an object to be cleaned to pass therethrough but allows foreign matters attached to the object to be cleaned and vegetable wastes to pass through.

The mounting frame 14 is a fixed part for supporting and mounting the outer periphery of the wire net 13, and has slide mounting parts 17 for slidingly attaching and detaching the left and right ends of the wire net 13, and the lower part of the mounting frame 14 is attached to the aquarium body. It is rotatably supported, and a rod 18 for driving the mounting frame back and forth is connected to the upper part.
Instead of the slide mounting portion 17, it is also possible to fix it with a screw, a hook, or the like. It is also possible to use punching plates instead of wire mesh.

The drive unit 15 includes a motor 19 and an eccentric cam mechanism 20 (eccentric disc cam) that connects the rod to one end deviated from the center of the disc rotated by the motor 19 and moves the rod back and forth as the disc rotates. ..
The rotation of the motor 19 causes the rod 18 to move back and forth via the eccentric cam mechanism 20. Since the lower portion of the mounting frame 14 is rotatably supported, when the rod 18 extends, the tip of the rod 18 tilts the mounting frame 14 inward about 20°. When the rod 18 retracts, the mounting frame 14 is returned to the vertical position. By repeating the forward/backward movement of the rod 18, the mounting frame 14 and the wire net 13 perform a swinging motion in which the mounting frame 14 and the wire net 13 are repeatedly tilted from the vertical position to the tilted position.

Since the oscillating means 5 oscillates (reciprocates), the object to be cleaned sticks to and separates from the wire netting 13 repeatedly, does not remain attached to the wire netting, and is used without impairing the foreign substance removing effect. However, in order to more surely prevent the object to be cleaned from sticking, a sticking prevention plate 16 is provided behind the swinging means 5 from the side surface of the water tank as shown in FIGS. ..
The water tank behind the rocking means 5 has an inclined side surface 26 whose upper side is open to the outside, and is configured to overflow and drain beyond the upper end of the inclined side surface 26. Then, mounting pieces 16a are projected from two locations on the inclined side surface 26 at intervals in the horizontal direction, and both ends of the sticking prevention plate 16 are mounted and fixed to the mounting pieces 16a.
The sticking prevention plate 16 is disposed in the horizontal position of the water tank at a position close to the back of the center of the wire mesh in the vertical position, and has a shape in which the upper and lower sides of the horizontally long plate material are slightly bent toward the wire mesh. Has been done.
Further, the upper end of the sticking prevention plate 16 is set to be slightly higher than or equal to the overflow water level.
With such a configuration, when the wire mesh 13 of the swinging means 5 retracts, the object to be cleaned stuck to the wire mesh 13 and the sticking prevention plate 16 are in a state of sandwiching water between them. The bounced water flow can further eliminate sticking of the object to be cleaned.
The shape, position, size, etc. of the sticking prevention plate 16 are appropriately set depending on the object to be cleaned, the direction of the jet water flow, the strength, and the like. Further, the sticking prevention plate 16 may be attached at an angle with respect to the traveling direction of the water flow.

A washing water jet nozzle 4 is arranged opposite to the swinging means 5, and the water flow jetted from the washing water jetting nozzle 4 is jetted toward the swinging means 5. The object to be washed, which is made to flow by the water jetted from 4, is returned to the center of the water tank 1. Therefore, the object to be cleaned is cleaned while repeating the floating and sinking inversion between the cleaning water jet nozzle 4 and the swinging means 5.
The foreign matter such as dust removed by receiving the jet of water flow passes through the wire net 13 and is discharged to the gutter 22 of the overflow part 21 behind the wire mesh 13 and reaches the filter bag 23 along the inclination of the gutter 22 and the overflow filter tank. It is stored in 6. In addition, foreign matters such as dust floating in the water pass through the wire mesh, are sucked through the suction/discharge port 24, pass through the filter bag 25, and are stored in the underwater filtration tank 7.

An aeration device 27 is provided at the bottom of the water tank.
This aeration device 27 includes three rows of pipes inserted in the bottom of a water tank, horizontal pipes connecting the tip and base ends of the pipes, aeration nozzles 3 provided at predetermined intervals on the upper surfaces of the pipes, and pipes. And a blower 28 for sending air to the lateral pipe.
Each of the aeration nozzles 3 is inclined toward the downstream side, and the air sent from the blower 28 which is inclined and protrudes toward the rocking device side to push the object to be cleaned toward the wire mesh side of the rocking means is the aeration nozzle. Air is blown (bubbling) from the entire bottom of the water tank by 3, and a water flow is generated along the jet direction of the air from the aeration nozzle 3 toward the rocking device, and at the same time, a water flow is generated from upstream to downstream. It also functions as a means. Further, cleaning of the object to be cleaned is also performed by bubbling and water flow.
The inclination of the aeration nozzle 3 can be set at an angle depending on the arrangement position. For example, it is possible to mount the apparatus near the input port or near the outlet of the rocking means while being inclined toward the downstream side, and near the rocking means while tilting toward the downstream side and the rocking means side.

A partition 29 (a punching plate) having a shape obtained by cutting out the aeration nozzle 3 in a circular shape is provided on the upper surface of the aeration device.
The partition 29 is arranged at the same height as the tip of the aeration nozzle 3, exposing only the ejection port of the aeration nozzle 3.
The partition 29 constitutes upper and lower partitions of the water tank 1, and a basin is secured between the bottom of the water tank 1 and the partition. Therefore, a return path for returning the water flow is formed on the lower side of the water tank with respect to the outward path of the water flow on the upper side of the water tank 1.
The partition 29 is provided over the entire bottom of the water tank, and a water passage hole is appropriately provided in the partition.

On a side surface of the water tank, an overflow filtration tank 6 for filtering and storing water discharged by overflow of the water tank, and an underwater filtration tank 7 for filtering and storing water sucked from water in the water tank are provided.
The overflow filtration tank 6 and the submersible filtration tank 7 are provided with filtration bags 23, 23a, 25 made of fine mesh fabric, respectively, and the water flowing out from the water tank is introduced into the filtration bag to collect dust and the like. After that, water is stored in the tank.

The overflow filtration tank 6 stores water discharged from an overflow portion 21 (overflow foreign matter discharge portion) provided behind the wire net of the swinging means through a trough. In the overflow portion 21, foreign matter floating on the water surface passes through the wire mesh and is introduced into the filter bag 23 and collected.
An overflow portion 21a (overflow foreign matter discharge portion) is also installed at the downstream end of the water tank, and the floating foreign matter that has flowed down downstream is introduced into the filtration bag 23a through the trough and collected.
The water stored in the overflow filtration tank 6 is jetted from the jet port 2 on the upstream side of the water tank via the pipe by the circulation pump 6a.

The submersible filtration tank 7 stores the water sucked from two suction outlets 24 (suction foreign matter discharge portions) provided in the water behind the wire net 13 of the rocking means 5. The foreign matter floating in the water passes through the wire mesh, is sucked through the suction outlet 24, is introduced into the filter bag 25, and is collected. The intake/exhaust ports 24 are not limited to two locations, and may be installed in one location or in three or more locations.
The water stored in the submersible filtration tank 7 is circulated and jetted by the circulation pump 7a to the wash water jet nozzle 4 through the pipe.
Here, the water level of the submersible filtration tank 7 is set lower than the water level of the water tank 1 by the circulation of water by the circulation pump 7a. That is, since a water level difference h is formed between the water level discharged by the overflow part 21 and the water level of the submersible filtration tank (see FIG. 3), water is sucked and discharged from the suction/discharge port 24 connected to the water to the submersible filtration tank 7. To be done.
Light dust floating on water is discharged from the upper overflow section 21 to the overflow filtration tank 6, and dust floating in water is discharged from the lower suction port 24 to the submersible filtration tank 7.

Next, a method of using the food cleaning device will be described.
The cut object such as cabbage is put into the inlet 10 of the water tank.
The object to be cleaned that has been introduced is transferred downstream by the injection port 2 and the aeration nozzle 3 (water flow generation means).
Since the washing water jet nozzle 4 for jetting a water flow to the object to be washed is provided on the right side surface of the water tank 1 from the upstream side to the downstream side, the strong water flow from the jet nozzle sufficiently cleans the food material.
Although the object to be cleaned is washed away to the side surface of the water tank by receiving the water sprayed from the cleaning water spray nozzle 4, the wire netting 13 is swung toward the inside of the water tank, and is pushed back to the rocking wire netting 13. While being washed up and down, it is washed.
Although the object to be cleaned may stick to the wire net 13 due to the operation of the apparatus, since the sticking prevention plate 16 is provided, the object to be cleaned separates from the wire net 13 due to the bounce water flow.
Foreign matter such as floating dust passes through the wire mesh of the rocking means and is discharged from the overflow portion 21 behind. The foreign matter that reaches the downstream side is discharged from the overflow portion 21a.
Further, the foreign matter drifting in the water passes through the wire net 13 and is discharged from the suction/discharge port 24.

The water stored in the overflow filtration tank 6 is jetted from the jet port 2 on the upstream side of the water tank via the pipe by the circulation pump 6a.
The water stored in the submersible filtration tank 7 is jetted from the wash water jet nozzle 4 by a circulation pump 7a via a pipe.
Here, since the water level of the submersible filtration tank 7 is always set lower than the water level of the water tank 1 by the circulation pump, water is sucked and discharged from the suction/discharge port 24 of the water tank.

The article to be cleaned which has flowed through the water tank 1 and reaches the downstream side is discharged by the discharge conveyor 12.
A shower is set on the discharge conveyor 12 as needed, and a final cleaning operation is performed.
Since the partition 29 is provided at the bottom of the water tank 1, a return path for returning the water flow is formed on the lower side of the water tank with respect to the forward path of the water flow on the upper side of the water tank, and a smooth flow of the forward path and the return path is formed. It
Heavy foreign matter, sand, pebbles, metal debris, etc. accumulated on the bottom of the water tank 1 can be easily cleaned by removing the partition 29.
During operation, fresh water is constantly supplied from the water supply port 30 toward the downstream side to generate a water flow together with the injection port and the aeration nozzle.

Although the embodiment of the present invention has been described above, the specific configuration of the present invention is not limited to the present embodiment, and even if there is a setting change or the like within a range not departing from the gist of the invention, it is included in the present invention. Be done.
For example, the cabbage has been described in the above embodiments, but the present invention is not limited to this, and can be applied to other vegetables, seafood, meat and other food ingredients.
Further, for the wire net 13 described in the embodiment, it is possible to use a member having a water passage hole such as a punching plate.
