Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention removes impurities such as small crab, shrimp, scale, needles and other garbage mixed in raw materials of shirasu, burrs, iriko, and other landed small fish, and boiled them. The present invention relates to a device for removing impurities that can increase the commercial value of small fish products such as shrimp.

[0002]

2. Description of the Related Art Small crab, shrimp, scale, needles and other miscellaneous garbage are often contaminated when small fish are landed in a fishery. Therefore, when boiling small fish using an automatic kettle, impurities are removed by hand and removed. However, since this method cannot completely remove impurities, a method of appropriately drying a small fish containing many impurities and then blowing off the impurities by wind separation is generally used.

Another method is to boil small fish,
A method has also been adopted in which a raw material containing impurities is put into salt water, and the raw material and the impurities are separated at a specific gravity. Further, in a method known as a separation separation method, separation and separation are performed in which raw materials are separated into pieces by boiling, and the mixture is blown off by a wind force of a separator to remove light impurities far away. Further, a sorting device utilizing the property of static electricity has been partially adopted.

On the other hand, Japanese Patent Application No. 8-112930 (Japanese Patent Application Laid-Open No. 9-266735) discloses a lower conveyor for transporting a mixture of small fish and a smaller mixture thereof, and a lower conveyor facing the lower conveyor. An upper conveyor is provided, and both conveyors are constituted by belts through which air such as a mesh belt can pass, and a blow-up nozzle for blowing up the mixture on the lower belt on the transport side is provided on the lower conveyor, and is opposed to the lower belt. A sorter for small fish or the like is disclosed in which an upper belt is provided with a negative pressure section for adsorbing the blown up mixture and a discharge section for discharging the mixture adsorbed on the upper belt downstream thereof. .

[0005]

The method of blowing out impurities by the above-mentioned small fish after drying the small fish by wind power sorting requires time and labor for the recovery work after the blowing, and the light impurities are far away when the impurities are blown away. The relatively large impurities that fly, however, do not have a sufficient degree of flight, and have the disadvantage that they are mixed into the product again. Further, there is a problem that unsightly impurities such as red fish and scale attached to the fish body of the small fish can hardly be separated.

In particular, since the wind power is used, if the small fish are not dried to some extent, the raw materials and impurities will not be sufficiently separated in the air when blown off, and will be effective for a mixture containing water. Can not. In many cases, small fish are still attached to the impurities blown further away, and there is a disadvantage that raw materials are wasted.

[0007] Further, the method of boiling the small fish, putting the raw material mixed with impurities into salt water, and separating the raw material and the impurities at a specific gravity is difficult to incorporate into an automated flow operation. However, there is a problem that the freshness of small fish or the like as a raw material is reduced to cause rot or the like, or the finished color or luster is impaired, and the commercial value is reduced.

Therefore, in order to effectively separate impurities, a method of separating and separating after boiling is effective. However, this method is to raise the product once by an elevating conveyor or the like, and then uniformly apply the product to a vibration hopper. Means for charging and sending the liquid to the front of the nozzle through the vibrating hopper are usually used.
However, since the product sent from the hopper is only blown upward and forward by the nozzle when dropped, there is a problem that if a large amount of the product is dropped, impurities cannot be sufficiently removed. Furthermore, there are many cases where a dryer and a sorter cannot be installed in a limited factory space.

As another method, a sorting device utilizing the property of static electricity is also known. However, the static electricity generating device is expensive, and the method using static electricity makes it difficult to forcibly absorb impurities, and the sorting efficiency per unit time is low. It has the disadvantage of being bad. Further, according to the sorting apparatus described in Japanese Patent Application Laid-Open No. 9-266735, a negative pressure unit for adsorbing the blown-up impurities or a plurality of discharges for discharging the impurities adsorbed on the upper belt on the downstream side thereof. Since the parts must be provided, there is a drawback that the mechanism is complicated mechanically, and that a plurality of discharge parts are provided, so that a work loss is likely to occur and an efficient impurity removing work cannot be performed.

Therefore, the present invention solves the problems of the conventional apparatus for removing impurities such as small fishes, and can perform an efficient impurity removal operation with a relatively simple mechanism. It is an object of the present invention to provide a device for removing impurities such as small fish that can be installed in a designated factory space.

[0011]

In order to solve the above-mentioned problems, the present invention is directed to a product transport conveyor formed in a mesh or a porous form for transporting a mixture of small fish and impurities according to claim 1; A mesh belt disposed at an upper position facing the product transport conveyor so as to be endlessly rotatable, an impurity removal conveyor disposed at one end of the mesh belt on an impurity discharge side, and a lower portion of the product transport conveyor Air blower fan with heater for blowing hot air through a blow duct, and a single or multiple product blow-up nozzles provided at the lower part of the product transport conveyor, and a number of modified examples are added thereto. It is configured as a device for removing impurities such as small fish.

According to the apparatus for removing impurities such as small fish having the basic configuration, when the mixture containing the small fish fried in the kettle and the impurities is carried in by the product transport conveyor and the air blowing fan is started at the same time, the suction is performed. The air is heated by the heater, introduced into the lower part of the product conveying conveyor via the blowing duct, and blows hot air upward from the product blowing nozzle. Only the light impurities to be removed from the mixture are blown up by the hot air and adhere to the mesh belt, and are dropped and conveyed on an impurity removing conveyor provided at one end on the impurity discharging side. Hereinafter, an efficient impurity removing operation can be performed by adding a number of modifications.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Various embodiments of the present invention will be described below with reference to the drawings. In any of the following embodiments, the main purpose is to efficiently remove small crabs, shrimp, scales, needles and other miscellaneous garbage and impurities that are frequently mixed in the small fish as a raw material to enhance the commercial value of the small fish. Has become.

FIG. 1A is a front view showing a first embodiment of the present invention, and FIG. 1B is a left side view of the same. Reference numeral 1 in the figure denotes a product transport conveyor, which is disposed between lower rollers 2 and 2 so as to be capable of endless rotation. The product transport conveyor 1 itself is formed in a porous or mesh shape through which air can pass. A mesh belt 4 is disposed between the upper rollers 3 and 3 at an upper position facing the product transport conveyor 1 so as to be capable of endless rotation. 5 is a mesh belt 4
Is a tension roller for adjusting the tension of the roller, 6 is a brush, and 7 is a conveyor for removing impurities. The rotation direction of the conveyer 7 for removing impurities has an angle of 90 degrees with the rotation direction of the product transport conveyor 1 in a plan view.

Reference numeral 8 denotes an air blowing fan, and a heater 9 is provided near the air blowing fan 8.
The blow duct 1 derived from the air blow fan 8
0 extends downward and is introduced into the lower part of the product transport conveyor 1. A single or a plurality of product blowing nozzles are provided below the product conveyor 1. The shape and location of the product blow-up nozzle will be described later in a third embodiment and thereafter.

A mesh through which air can pass is formed on the mesh belt 4, and an exhaust hood 11 is disposed above the mesh belt 4. A ventilation fan (not shown) is provided in the exhaust hood 11, and the exhaust hood 11 is connected to a suction blower (not shown).

Reference numeral 12 denotes a housing constituting an outer shell member, and the entire apparatus is hermetically sealed by the housing 12. In FIG. 1B, 13 is a cleaning door on the upper surface or the inner wall surface of the product transport conveyor 1, and 14 is a cleaning door on a lower portion of the product transport conveyor 1.

The smaller the mesh of the mesh belt 4 is, the smaller the dust in the impurities does not pass through and can be prevented from scattering to the outside. However, if the mesh is too small, the suction force decreases, and conversely, the mesh becomes large. If too much, there is a risk of sucking up raw materials such as small fish. Therefore, the size of the mesh eyes is
About 0.1 mm to 30 mm is appropriate.

The operation of the first embodiment will be described. Small fish such as landed shirasu, fowl, iriko, etc.
It is a mixture containing impurities such as needles, nets, small crabs and scales. When the air blow fan 8 is started at the same time that the mixture fried in the kettle is carried in by the product transport conveyor 1, the sucked air is heated by the heater 9, and is introduced into the lower portion of the product transport conveyor 1 through the blow duct 10. It is introduced and blows hot air upward from the product blowing nozzle. The hot air blows light impurities in the mixture upward, and is sucked into the exhaust hood 11 by a ventilation fan or a suction blower.

The volume and pressure of the air from the product blowing nozzle are adjusted so that the mixture is blown up to the extent that the raw fish does not hurt and adheres to the mesh belt 4. By this adjustment, small fish of the raw material is blown up so as to be scattered in the space between the product transport conveyor 1 and the mesh belt 4,
Anything heavier than the impurities is not sprayed on the mesh belt 4, and only the impurities to be removed can be attached.

Since small fish and the like are slightly heavier than the impurities, they are not blown up as high as the impurities even under the same wind pressure, and only the highly scattered impurities are adsorbed and separated by the mesh belt 4. The distance between the product conveyor 1 and the mesh belt 4 provided above, the pressure of the product blow-up nozzle, the suction force of the exhaust hood 11, the tension roller 5
By appropriately adjusting the tension of the mesh belt 4 by the above, the effect of removing impurities can be enhanced.

For example, when the impurities have a large amount of water, such as when fried in a kettle, they adhere to the mesh belt 4 as they are,
By rotating the mesh belt 4 between the upper rollers 3 and 3 in a direction opposite to that of the product transport conveyor 1 to transport the impurities, the impurities are scraped off by the brush 6 and fall onto the impurity removing conveyor 7, and the product is removed. It is conveyed in a direction shifted by 90 degrees from the conveyor 1 in plan view.

Since the mesh belt 4 itself has no power to attract impurities, the sufficiently dry impurities without moisture pass through the mesh belt 4 and are sucked into the exhaust hood 11 by a ventilation fan or a suction blower. Will be released. Also, if the dust is forcibly collected by a dust collector or the like near the outlet of the exhaust hood 11, it is possible to prevent fine impurities from being diffused outward.

The apparatus for removing impurities according to the first embodiment comprises:
The use of the air blowing fan 8 provided with the heater 9 also serves as a dryer for small fish products.
One. Conventionally, if you want to remove a little water from the product after the pot is fried, you have to take the means of drying in the sun or using a drier, but drying in the sun is complicated, The other dryer is expensive and the total length of the dryer itself is usually 10 meters or more, and there is a problem in space. On the other hand, in the case of the first embodiment, the product is placed on the product transport conveyor 1. And dry easily by blowing hot air from below.

If the temperature of the hot air is too high, the product may be stuffy or the color may be reduced, and the commercial value may be reduced.
In this example, the temperature is set to a temperature condition that enables efficient drying without excessively increasing the temperature of the hot air. In particular, since the product blown up by hot air is in a disintegrated state, the penetration of hot air into the product is improved, and the drying effect can be further enhanced.

In the process of removing impurities, ordinary impurities are light and the case where the product is heavy can remove the impurities most efficiently. With hot air alone, the inside of a product such as a small fish is not sufficiently dried, and impurities are more dried, so that impurities can be more effectively removed. Further, even if the transport distance of the product is short, the product moves while moving up and down due to the hot air, so that even in a small space, the substantial transport distance can be extended and the drying effect can be enhanced.

Further, by dividing the impurity removing section constituted by the mesh belt 4 into two parts, a former stage and a latter stage, a high-moisture impurity is quickly taken out on the loading side of the mixture of small fish and the impurity, and slightly dried on the unloading side. Impurities can be taken out. At this time, it is effective to adjust the distance of the mesh belt 4, the blowing pressure from the product blowing nozzle, and the suction force of the exhaust hood 11 to be different between the former stage and the latter stage. By increasing the number of impurity removing units to three or four, the above-mentioned effect is great. Further, it is possible to remove impurities in the first stage and select the size of products such as small fishes by adjusting the wind force in the second stage. .

As described in detail above, the basic structure of the apparatus for removing impurities such as small fish according to the present invention is a product transporting apparatus which is formed in a mesh or porous shape and transports a mixture of small fish and impurities. A conveyor, a mesh belt disposed at an upper position opposed to the product transfer conveyor and arranged endlessly rotatable, an impurity removal conveyor arranged at one end of the mesh belt on an impurity discharge side, and a product transfer It has an air blowing fan with a heater for blowing hot air through a blowing duct at the lower part of the conveyor, and a single or a plurality of product blowing nozzles provided at the lower part of the product conveying conveyor. Using an upper net arranged rotatably and endlessly, and an impurity scraping roller or dust collector on a mesh belt or upper net The example provided nozzle is intended to include many variations described in other claims.

As a common effect to these, at the same time that the mixture containing the small fish fried in the pot and the impurities is carried in by the product transport conveyor, the air heated by the heater is blown up from the lower portion of the product transport conveyor by the nozzle and upward. By blowing up, only the lightweight impurities to be removed can be blown up and attached to the mesh belt or the upper net, and can be conveyed to the outside from the impurity removal conveyor.

In particular, unlike the conventional method in which small fish are dried and then impurities are simply blown off by wind power separation, no labor is required for the recovery work after blowing out, and air heated by a heater is used. By doing so, it is possible to separate unsightly impurities such as red fish and scales attached to the fish body of the small fish. In addition, there is no case where small fish remain attached to impurities blown away in a distant place, and the recovery yield of raw materials can be increased.

The present invention can reduce the freshness of the raw material such as small fish or cause decay as in the method of separating the raw material and the impurities by specific gravity, which can be incorporated into an automated flow operation. And enhance the color and luster of the small fish at the time of finishing to improve its commercial value. Further, since the apparatus itself is simplified as compared with the conventional example, it can be easily installed even in a small factory space.
