Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an apparatus for washing fresh foods such as pickled leafy vegetables such as mustard greens, green vegetables, Nozawana, Chinese cabbage, and Hiroshima cabbage, fruits, and seaweed.

(Prior art and problems) For example, a method of washing leafy vegetables used for pickling is to wash them while showering them with air bubbles in a water tank. Since the air bubbles are ejected from the bottom of the container, the air bubbles diffuse as they rise, making it impossible to concentrate the air bubbles on the leafy vegetables.
There is a problem that a sufficient cleaning effect cannot be obtained.

In addition, with conventional washing equipment, leafy vegetables are forcibly transferred using a net conveyor suspended in a water tank, which not only requires a large-scale equipment, but also requires handling, maintenance, and inspection. There were problems in that it required a lot of labor and was also expensive.

(Means for solving the problem) The present invention was made with the purpose of solving the above-mentioned problem, and in order to achieve this purpose, the present invention includes an inlet for the material to be washed at one end. In addition, at the other end, a circulation channel is defined by a partition plate that divides the inside of the water tank into upper and lower parts each having an outlet, and the upper part is a washing channel and the lower part is a return channel. A plurality of blowholes are arranged in a row along the length of the bottom, and the blowholes are arranged in a plurality of rows in the width direction of the washing path so that bubbles rise almost evenly in the width direction of the washing path. and the jet nozzle is provided in an inclined manner toward the outlet side of the washing passage, and the inclination angle of the jet nozzle from the vertical direction becomes gradually smaller as it goes toward the outlet side, and A washing device in which a plurality of fountain nozzles that open toward the outlet side of the washing channel are arranged in the width direction of the washing channel so that water is sprayed approximately evenly in the width direction of the washing channel. The partition plate has a large number of holes, and the partition plate is detachably attached to the water tank.

(Function) Therefore, in the device for washing fresh food such as leafy vegetables of the present invention, as described above, the partition plate that partitions the interior of the water tank into upper and lower parts creates a circulation channel in which the upper part is a washing channel and the lower part is a return channel. is formed, and the blowholes are arranged in a row along the length direction at the inner bottom of the washing channel,
Since air bubbles can be concentratedly sprayed onto the object to be washed within a limited area within the washing path, the air bubbles are not wasted and the mud that has firmly adhered and invaded the roots and stems of the object to be washed can be removed. It is possible to completely remove insects, insects, etc., and the leaves can be widely expanded by air bubbles, so that the cleaning effect can be significantly improved, such as cleaning every corner.

In addition, since the material to be washed is transferred by the inclination of the jet nozzle and the flowing action of the water jetted from the fountain nozzle, there is no need to provide a separate transfer device, which reduces the cost by simplifying the device. In addition, cleaning and maintenance of the device becomes easier.

In addition, by providing a fountain nozzle, it becomes possible to smoothly feed a large amount of items to be washed from the input port into the washing path, and moreover, multiple fountain nozzles are arranged in the width direction of the washing path. By providing this, it is possible to prevent shifting and ensure reliable feeding, and therefore, it is possible to significantly improve cleaning efficiency.

In addition, by arranging multiple rows of blowholes in the width direction of the washing path, it is possible to prevent the washing water from flowing in the width direction due to the rise of uneven air bubbles.
Transfer defects due to unevenness of the objects to be washed are eliminated.

In addition, since the inclination angle of the fumarole from the vertical direction is formed so that it gradually becomes smaller as it goes toward the outlet, the transfer speed of leafy vegetables becomes slower as it goes toward the outlet, and air bubbles The cleaning effect can be improved. In addition, the partition plate has a large number of holes and is formed so that it can be attached to and removed from the water tank, so that sand, etc. separated from the objects to be washed due to air bubbles can fall through the holes and reach the bottom of the water tank. It is easy to clean.

In the figure, reference numeral 8 denotes a lifting net conveyor, which is provided in an inclined manner with its lower end inserted into the water storage tank 1 on the side of the outlet 32 of the washing path 3.

Next, the operation of the embodiment will be explained.

This embodiment is configured as described above, so
Leafy vegetables W, such as Chinese cabbage split in half, which are inputted from the input port 31 are first directed toward the output port 32 through four fountain nozzles 6 arranged to equally divide the width of the washing path 3. Due to the force of the washing water evenly sprayed toward the vegetables, the leafy vegetables W are smoothly fed into the washing path 3 without being shifted to one side.

Next, inside the washing path 3, air bubbles are generated by the air ejected from the jet nozzle 5, and these air bubbles are ejected from the obliquely opened jet nozzle 5 toward the extraction port 32 side. Therefore, the washing water H in the washing channel 3 flows from the input port 31 side to the outlet port 32 side, so the leafy vegetables W sent into the washing channel 3 are taken out while being urged by the flow of the washing water. It is transferred to the outlet 32 side, and during the transfer, it is washed while being exposed to air bubbles.

In this case, the leafy vegetables W move while repeatedly floating up and down due to the floating action caused by being exposed to air bubbles from below and the sinking action due to their own weight,
In addition, the air bubbles diffuse the leaves, and by showering the diffused leaves with air bubbles, insects, soil, etc. that have entered between the leaves are separated, and the leafy vegetables W are washed. By the way, this washing is washing path 3.
By performing this within a regulated area inside the container, the leafy vegetables W can be intensively and efficiently exposed to air bubbles, so that a sufficient cleaning effect can be obtained and the air bubbles can be used effectively. Washing becomes possible.

Moreover, the fumarole 5 is 3 in the width direction of the washing path 3.
By arranging them in rows, the air bubbles ejected from the nozzle ports 5 of each row rise in a uniform manner in the width direction within the cleaning path 3, so that uneven air bubbles rise in the width direction. The leafy vegetables W are not pushed toward the inner wall surface of the washing path 3 by the flow of the washing water, and therefore can be smoothly moved inside the washing path 3.

The leafy vegetables W that have been thoroughly washed in the washing path 3 as described above are successively pulled up to the outside of the water storage tank 1 by the pulling net conveyor 8 at the outlet 32.

In addition, among the garbage separated from the leafy vegetables W during washing, the garbage floating on the water surface is transferred to the overflow hole 1.
0 to the outside with overflow water,
In addition, sediment such as sand falls through the various holes 21 and elongated holes 22 provided in the partition plate 2 and accumulates in the return flow path 4 that forms the bottom of the water storage tank 1.

Further, the water injected from the fountain nozzle 6 is sucked from the suction channel 24 by the pump P, and is circulated after being filtered to remove dust and the like by the strainer 63.

Incidentally, the dust such as sand accumulated in the return channel 4 can be discharged to the outside together with the cleaning water H by opening the discharge valve 11 after the work is completed, and the debris such as sand accumulated in the return flow path 4 can be discharged to the outside together with the cleaning water H. By removing each partition plate 2, the inside of the water storage tank 1 can be cleaned easily.

As explained above, in the leafy vegetable washing device A of this embodiment, the partition plate 2 that partitions the inside of the water tank 1 into upper and lower parts allows the upper part to be used as the washing passage 3 and the lower part to be used as the return flow. A circulation flow path 4 is formed, and blowholes 5 are arranged along the length of the inner bottom of the cleaning path 3, so that air bubbles are removed from the cleaning path 3.
Since the spray can be concentrated on the leafy vegetables W within a limited area, without wasting air bubbles, it can remove mud, insects, etc. that have firmly adhered to and invaded the roots and stems of the leafy vegetables W. In addition to being able to completely remove the leaves, the leaves can be greatly expanded by air bubbles, making it possible to clean every nook and cranny, thereby significantly improving the cleaning effect.

Furthermore, since the transfer of the leafy vegetables W is carried out by the inclination of the blowhole 5 and the flowing action of the water jetted from the fountain nozzle 6, there is no need to provide a separate transfer device.
Therefore, by simplifying the device, the cost can be reduced, and cleaning and maintenance of the device can be easily performed.

In addition, by providing the fountain nozzle 6, it becomes possible to smoothly feed a large amount of leafy vegetables W input from the input port into the washing path 3, and the fountain nozzle 6 is arranged in the width direction of the washing path 3. By arranging four of them, shifting can be prevented and feeding can be carried out reliably, thus making it possible to significantly improve cleaning efficiency.

Moreover, the fumarole 5 is 3 in the width direction of the washing path 3.
By arranging them in rows, it is possible to prevent the cleaning water from flowing in the width direction due to the rise of air bubbles that are lopsided, so that there is no possibility of transport failures due to the lopsidedness of the leafy vegetables W.

In addition, in the embodiment, each cover 33 that closes the upper opening of the washing path 3 can be opened and closed, and each partition plate 2 is made detachable, so that the cleaning work inside the water storage tank 1 is facilitated. Be able to do it.

Although the embodiments of the present invention have been described above in detail with reference to the drawings, the specific configuration is not limited to these embodiments, and the present invention may be modified without departing from the gist of the present invention. included.

For example, in the embodiment, four fountain nozzles 6 are provided, but the number is not limited, and the point is that a large amount of material to be washed is thrown into the washing path 3 from the inlet 31 with an even force. The width is determined according to the width of the washing path 3 so that the washing can be fed smoothly, but at least two or more are required.

Further, in the embodiment, the blowholes 5 are arranged in three rows in the width direction of the washing path 3, but the invention is not limited to this, and in short, it is determined according to the width of the washing path 3, but at least two or more Otherwise, water will flow toward the side wall, resulting in poor transfer of the material to be washed.

(Effects of the invention) As explained above, in the device for washing fresh foods such as leafy vegetables of the present invention, the upper part is used as a washing channel and the lower part is used as a return flow channel using a partition plate that divides the interior of the water tank into upper and lower parts. A circulation flow path is formed, and by arranging the blowholes along the length of the inner bottom of the washing path, air bubbles are directed against the object to be washed within a limited range within the washing path. Since the water can be sprayed intensively, it is possible to completely remove mud, insects, etc. that have firmly adhered to and invaded the roots and stems of the object to be washed, without wasting air bubbles. Since this can be expanded widely by air bubbles, the cleaning effect can be significantly improved, such as by cleaning every nook and cranny.

In addition, since the material to be washed is transferred by the inclination of the jet nozzle and the flowing action of the water jetted from the fountain nozzle, there is no need to provide a separate transfer device, which reduces the cost by simplifying the device. In addition, cleaning and maintenance of the device becomes easier.

In addition, by providing a fountain nozzle, it becomes possible to smoothly feed a large amount of items to be washed from the input port into the washing path, and moreover, multiple fountain nozzles are arranged in the width direction of the washing path. By providing this, it is possible to prevent shifting and ensure reliable feeding, and therefore, it is possible to significantly improve cleaning efficiency.

In addition, by arranging multiple rows of blowholes in the width direction of the washing path, it is possible to prevent the washing water from flowing in the width direction due to the rise of uneven air bubbles.
This has the effect that transport defects due to unevenness of the objects to be washed will not occur.

In addition, since the inclination angle of the fumarole from the vertical direction is formed so that it gradually becomes smaller as it goes toward the outlet side, the transfer speed of leafy vegetables becomes slower as it goes toward the outlet side, and the The effect is that the cleaning effect can be improved. In addition, the partition plate has a large number of holes and is detachable from the water tank, so that sand, etc. separated from the object to be washed due to air bubbles is allowed to fall through the holes and reach the bottom of the water tank. It is easy to clean.
