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 for removing foreign matter such as small dust such as hair attached to food such as cut vegetables.

[0002]

2. Description of the Related Art In general, foods such as cut vegetables are washed with water by various washing methods to remove foreign substances such as soil and dust.

[0003] As the above-mentioned washing method, a method of storing food in a container such as a water tank and injecting high-pressure water from above,
There is a method of bubbling by blowing air from the inside.

[0004]

However, in the above-described cleaning method, foreign substances having a specific gravity higher than that of water such as soil can sink to the bottom of the water and be removed. Although small and small foreign matter is separated from the food by the above-mentioned washing, it easily adheres to the food again. For this reason, it is necessary to manually remove fine foreign matter having a smaller specific gravity than water, which has been a serious operation.

It is an object of the present invention to easily remove fine foreign matters having a specific gravity smaller than that of water.

[0006]

In order to solve the above-mentioned problems, the present invention attaches a conveyor extending from the inside of the water tank to the outside at one end of the water tank, and extends the conveyor from the other end of the water tank to the conveyor. A net is attached to the inside of the water tank, and an air jetting part for jetting air upward is provided below the net, and a water flow toward one end of the water tank is provided on the net at the other end of the water tank. A water jetting section to be generated is provided, and a baffle plate having a large number of holes is installed above the net in the water tank in a direction facing the water flow.

[0007] Food is put into the other end of the water tank. The food moves toward one end of the aquarium according to the water flow. At this time, the food is separated from the foreign matter adhered to the food by bubbling from an air blowing portion provided below the net. Among these foreign substances, those having a specific gravity higher than water such as soil are settled at the bottom of the water tank and separated. In addition, foreign matter having a specific gravity smaller than that of water, particularly fine foreign matter such as hair, is caught by a baffle provided in the middle and removed.

[0008]

Embodiments of the present invention will be described below with reference to the drawings.

The foreign matter removing apparatus according to the present invention is shown in FIGS.
As shown in FIG. 3, this is an apparatus in which a conveyor 2 extending from the inside of the water tank 1 to the outside is attached to one end of the water tank 1. In this apparatus, a net 3 is attached in the water tank 1 from the other end of the water tank 1 to the conveyor 2.

In the water tank 1 below the net 3, an air jet unit 4 for jetting air upward is provided. The air injection unit 4 injects air sent from an air pump (not shown) from an injection hole 5 provided on the upper surface of the air injection unit 4 to bubble water in the water tank 1.

A water injection unit 6 is provided inside the water tank 1 and above the net 3 at the other end of the water tank 1. The injection port of the water injection unit 6 is directed to one end of the water tank,
Further, the water at the one end of the water tank 1 is supplied to the water injection unit 6 by a motor 7. Therefore, in the water above the net 3 of the water tank 1, a water flow is generated from the other end of the water tank 1 to one end.

Further, a baffle plate 8 having a large number of holes 9 is provided above the net 3 in the water tank 1. The baffle plate 8 is installed in a direction facing the water flow.
For example, as shown in FIG. 2, it can be installed in a direction orthogonal to the water flow. Since the baffle plate 8 has a large number of holes 9, it does not obstruct the water flow. However, the food put in the water tank 1 advances toward the conveyor 2 according to the water flow while colliding with the baffle plate 8. Then, the foreign matter is separated from the food by bubbling from the air ejection part 4.

[0013] The foreign matter refers to trash that adheres to or coexists with food or the like. This foreign matter, particularly a foreign matter having a specific gravity smaller than that of water and smaller than water (hereinafter, “small and low specific gravity foreign matter”) is caught in the hole 9 of the baffle plate 8 as shown in FIG. Thereby, the small and low specific gravity foreign matter is removed.

As shown in FIGS. 1 to 3, the baffle plate 8 is installed not only in a direction perpendicular to the water flow but also at a predetermined inclination angle with respect to a direction perpendicular to the water flow. Can be. In this manner, the degree to which the speed of the water flow is reduced by the baffle plate 8 can be reduced.
In addition, the force of the collision between the shed food 10 and the baffle plate 8 is also reduced, and it is possible to reduce scratches that easily occur on the food 10.

The above-mentioned predetermined inclination angle is not particularly limited, but may be any angle as long as a small and low specific gravity foreign matter can be hooked on the hole 9 of the baffle plate 8.

Further, the shape of the baffle plate 8 is not limited to a flat plate shape as shown in FIGS. 1 to 4, and various shapes can be used. For example, as shown in FIG. 5A, a flat plate may be bent in the middle and have a V-shaped cross section. As shown in FIG. 5B, the baffle plate 8 'can be mounted in the water tank 1 so as to resist the flow of water, so that the stability of the baffle plate is increased. In particular, when the surface of the baffle plate 8 ′ that directly contacts the water flow is disposed with the above-described predetermined inclination angle with respect to the direction perpendicular to the water flow, it is effective to maintain this inclination angle.

Further, as shown in FIGS. 5A and 5B,
The sides of the baffle 8 (8 '), i.e., edges, side edges,
A hook-shaped foreign matter stopping hook 12 may be attached to a bent portion or the like. In this side portion, the water becomes rapid, so that not only the food 10 but also the small and low-specific-gravity foreign matter 11 is easily moved. At this time, if the foreign matter stopping hook 12 is provided in this portion, the small and low specific gravity foreign matter 11 is caught and the movement thereof can be suppressed.

Next, the operation of the foreign matter removing apparatus according to the present invention will be described with reference to FIG.

Food is put into the water tank 1 from above the other end by any method. At this time, the food to be put in may be one that has already been washed with water by another method or one that has not been washed with water. When the main purpose is to remove small foreign matter having a low specific gravity such as hair, it is preferable to put in a food that has already been washed with water by another method.

The fed food is supplied to one end of the water tank 1, that is, the conveyor 2, in accordance with the water flow above the net 3.
Move toward. During this movement, foreign matters such as small and low-specific-gravity foreign matters are separated by bubbling from the air injection unit 4. In addition, the baffle plate 8 removes small and low specific gravity foreign matter.

The food from which the small and low-specific-gravity foreign matter has been separated and removed is conveyed to the conveyor 2 and sent to the next step.

The foods to which the foreign matter removing apparatus according to the present invention can be used are not particularly limited, and include vegetables such as cut vegetables, agricultural products such as cereals, fruits and beans, fish, shellfish, and the like.
Any foods such as marine products such as crustaceans such as shrimps, intermediate products and processed products of agricultural products and marine products can be mentioned.

The small and low-specific-gravity foreign substances removed by the foreign substance removing apparatus according to the present invention include hair, shells from which small shrimps have been peeled off, lint, and the like.

[0024]

According to the present invention, the specific gravity of hair and the like is smaller than that of water, and fine foreign matters can be easily removed. Therefore, the manual removal work can be simplified and the efficiency can be improved. it can.
