Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foreign matter removing device suitable for vegetables.

[0002]

2. Description of the Related Art Generally, vegetables shipped in large quantities are washed by a washing device.

[0003] In particular, in the case of vegetable salad or vegetables that are put directly into the mouth between breads, after washing, a step of spreading on a conveyor and checking for the presence of foreign matter, insects and the like is provided. It has become.

[0004]

At the present time, when vegetables are manually checked after washing, it is difficult to completely remove insects or foreign substances lurking between leaves, such as lettuce. .

In order to completely remove them, a great deal of labor and time are required.

Accordingly, an object of the present invention is to provide a foreign matter removing device capable of efficiently removing insects, foreign matter, and the like that enter the surface and inside of a vegetable during washing.

[0007]

According to the first aspect of the present invention, there is provided a washing tank having a strainer provided at a bottom drain, and a substantially intermediate portion of an inner wall surface of the washing tank. And a water supply pipe that supplies washing water into the washing tank and overflows the supplied washing water from the upper opening, and simultaneously feeds air and water into the washing tank, And an injection nozzle.

Thus, the vegetables put into the washing tank are washed while rotating. At this time, when the air bubbles injected from the injection nozzle hit and burst, the vegetables are vibrated and, for example, insects and foreign substances lurking between the leaves are expelled. Of the insects and foreign substances away from the vegetables, those with a low specific gravity emerge,
Overflow from upper opening. Heavy things will collect on the bottom strainer. In addition, the intermediate product is collected by the collection net, so that insects and foreign substances can be efficiently and reliably removed, and reattachment to vegetables is eliminated.

According to the second aspect of the present invention, the water jetted from the jet nozzle into the washing tank together with the air is used as the washing water overflowing from the upper opening of the washing tank.

[0010] Thus, by filtering and repeatedly using washing water used in large quantities, it is possible to save washing water, and it is very preferable in terms of washing cost.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be specifically described below with reference to FIGS.

In FIG. 1, reference numeral 1 denotes a cleaning tank of the foreign matter removing device 3. Inside the cleaning tank 1, a collection net 5 and an injection nozzle 7 are respectively arranged.

As shown in FIGS. 3 and 4, the collection net 5 has a predetermined receding angle with respect to the rotating water flow in the direction of the arrow at the locking portion 9 substantially at the intermediate portion of the inner wall surface of the washing tank 1. It is attached detachably. The intake 11 of the collection net 5 is formed in a rectangular shape with a rigid material, and has a shape in which a net of a large mesh is cut so that relatively large foreign matter, insects, etc. are taken in, and heads toward the rotating water flow. It has become.
Further, the collecting portion 13 of the collecting net 5 has a shape in which a small mesh net is provided. By removing the collecting net 5 from the locking portion 9, the collecting portion 13 can be replaced with a new one or collected. The inside of the unit 13 can be cleaned.

A detachable strainer 17 is provided at a drain port 15 at the bottom of the washing tank 1, and washing water is supplied into the washing tank 1 from an upper opening 21 by a water supply pipe 19. I have.

The water supply pipe 19 is connected to a water supply pipe (not shown), and by controlling a water supply valve 23, it is possible to cause the washing water to overflow from the upper opening 21 to the overflow water receiver 25.

The bottom of the overflow water receiver 25 is inclined downward toward the drain 27, and the drain 27 communicates with the temporary storage tank 29. Therefore, the washing water overflowing from the upper opening 21 of the washing tank 1 is sent from the overflow water receiver 25 to the temporary storage tank 29 via the strainer 31.

The temporary storage receiving tank 29 includes a drain port 15 at the bottom of the washing tank 1 and the overflow water receiver 25.
The solenoid valve 3 is connected to the drain pipe 33 through a drain pipe 33.
5, a flow control unit 37 and a strainer 39 are provided.

The temporary storage tank 29 is connected and connected to the injection nozzle 7 disposed in the washing tank 1 via a circulation pipe 41, and a drain pipe 43 for drainage is provided at the bottom, and an opening / closing valve is provided. By opening 45, drainage to the outside is possible.

The circulating pump 47 allows the overflow water in the temporary storage tank 29 to flow toward the injection nozzle 7 by the operation of the circulating pump 47 and the air supply pipe 51 provided with the electromagnetic valve 49. Compressed air is sent from a compressor (not shown) through the compressor. In this case, the means for feeding air does not necessarily need to use a compressor, and may be a means such as a blower.

The spray nozzles 7 are arranged at four locations so as to spray together with the water in a state where many bubbles and air are present in the water, and to provide a rotating water flow to the cleaning water in the cleaning tank 1. I have.

According to the thus configured foreign matter removing device 3, the washing water is supplied into the washing tank 1 by the water supply pipe 19 and overflows from the upper opening 21. At the same time, air and water are simultaneously injected from the injection nozzle 7 to create a rotating water flow. In this state, vegetables are put into the washing tank 1 and washing is performed by a rotating water flow. At this time, vibration is applied when the air bubbles injected from the injection nozzle 7 hit the vegetables or burst around the vegetables. Thereby, for example, insects and foreign substances lurking between the leaves are expelled. Insects and trash or foreign matter such as pebbles, sand, or soil,
Those having a low specific gravity overflow from the upper opening 21. Those having a high specific gravity collect in a strainer 17 provided in a drain port 15 at the bottom. In addition, the intermediate material is collected by the collection net 5.

By the way, an experiment was conducted on insects adhering to lettuce, green curls, and parsley, and as shown in FIG. 5, the number after the completion of washing was examined. As a result, good washing results were obtained with "none".

[0023]

As described above, according to the foreign matter removing apparatus of the present invention, insects, foreign matter, and dirt adhering to vegetables can be cleanly removed. In particular, for insects, a remarkable cleaning effect can be obtained.
