Description

  The present invention relates to an apparatus for removing foreign matter such as hair and small trash such as small insects from articles such as cut vegetables.

  Generally, foods such as cut vegetables are washed with water by various washing methods to remove foreign matters such as soil and dust. As this cleaning method, there are known a method in which food to be cleaned is stored in a water tank, a container or the like and high pressure water is injected from above, a method in which air is blown out from the inside and bubbling is performed.

  When the above method is used, foreign matter having a specific gravity greater than that of water such as soil can be settled and removed, but the specific gravity is smaller than that of water such as hair and lint, and fine foreign matter can be removed by the above washing. Although separated from food, it is easy to hit food again. On the other hand, it is known that by providing a baffle plate having a large number of small holes in the water tank, the small holes have a specific gravity lighter than that of water and fine foreign matters can be removed (see Patent Document 1).

JP 2000-210064 A

  However, in the case of the method of Patent Document 1, the food to be cleaned stays on the baffle plate, and there is a possibility that foreign matters will re-adhere during this stay.

  Accordingly, an object of the present invention is to more surely remove fine foreign substances with a specific gravity lighter than water.

  According to the present invention, a connecting hook part is provided between the hook parts provided on both sides of the foreign substance removing apparatus, and water is placed on the wall surface on the article input end side of the connecting hook part in the connecting hook member. The above-mentioned problem has been solved by providing an opening that can enter.

  The foreign matter to be removed tends to drift on the surface of the water in the aquarium because the specific gravity is lighter than water. For this reason, it is possible to efficiently remove foreign matters drifting on the surface of water by using a predetermined connecting rod member.

  As shown in FIGS. 1 to 2, the foreign matter removing apparatus according to the present invention feeds an article containing foreign matter (hereinafter referred to as “foreign matter-containing article”) a from one end of the water tank 11, It is an apparatus for taking out an article (hereinafter simply referred to as “article”) b from which foreign substances have been removed after removal.

  The said foreign material containing article a means the article for removing the foreign material adhering using the apparatus concerning this invention. Examples of this product include vegetables such as cut vegetables, agricultural products such as cereals, fruits and beans, marine products such as fish, shellfish and shellfish such as shrimp, and intermediate products of these agricultural products and marine products. Foods.

  Further, the foreign matter refers to something other than food that is attached to food. In particular, the foreign matter having a specific gravity lighter than water and fine (hereinafter referred to as “small and low specific gravity foreign matter”) is removed by the foreign matter according to the present invention. It can be removed with a device. Examples of such small and low specific gravity foreign substances include hair, lint, shells from which small shrimps are peeled off, and small insects.

  The water tank 11 can store water, and its shape is not particularly specified. In this specification, as shown in FIG.1 and FIG.2, it demonstrates using the rectangular parallelepiped water tank 11. FIG. This water tank 11 has a water supply unit 10 for supplying water, a discharge outlet (not shown), and a sluice 22, and water can be supplied and extracted freely.

  As the water supply unit 10, an upper portion of the water tank 11 is almost entirely extended along an end wall on one end (hereinafter referred to as “article input end”) side on the side where the foreign object-containing article a is input. The member which supplies water toward the inside of the water tank 11 is raised. Thereby, water is supplied like a waterfall from the upper part of the water tank 11 over substantially the whole surface along the end wall of the water tank 11 on the article input end side. For this reason, it can suppress that a turbulent flow generate | occur | produces in the water tank 11 by supply of water.

The sluice 22 is provided on an end wall of the water tank 11 on the other end (hereinafter referred to as “article take-out end”) side from which the article b is taken out. By opening the sluice 22, the water in the aquarium 11, particularly the surface water, flows out of the aquarium 11. Therefore, by the operation of the water supply unit 10 and the sluice 22, the water in the water tank 11, particularly the surface layer water on the water surface side, flows from the article input end side to the article take-out end side.

  The said water tank 11 is provided with the collar part 12 along the both sides | surfaces of the water tank 11 from the articles | goods injection | throwing-in edge part to an article | item taking-out edge part, respectively. The flange 12 receives the overflowing water from the aquarium 11, and at the same time, small and low specific gravity foreign matter that tends to float on the surface of the water in the aquarium 11 comes out with the overflowing water. it can. For this reason, a part of small-sized low specific gravity foreign material adhering to the said foreign material containing article a can be sent to this collar part 12, and can be separated from the said foreign material containing article a.

  It is preferable that the said collar part 12 is provided in contact with the outer side of the upper edge part of the both sides | surfaces of the said water tank 11. FIG. This is because the water overflowing from the water tank 11 can be received more efficiently by being provided at that position.

  Further, a conveyor 13 is provided at the article take-out end of the water tank 11 from the inside of the water tank 11 to the outside. Thereby, the article b can be taken out from the water tank 11.

  A connecting collar 14 is provided between the two collars 12 to connect them. As shown in FIG. 3, the connecting collar 14 can move water between the collar 12 and the coupling collar 14. For this reason, the water that has entered the connecting collar 14 can flow to the collar 12. Further, as clearly shown in FIG. 3, the connecting collar 14 is provided with an opening 15 on the wall surface on the article input end side so that water can enter the material of the connecting collar 14. By providing the opening 15, the water in the water tank 11, particularly the surface layer water, enters the connecting collar 14 from the opening 15. At this time, the small and low specific gravity foreign substances are drifting in the surface layer of the water in the water tank 11, and therefore can be put together in the connecting collar 14. In addition, this connection collar part 14 may be provided, and two or more plural may be provided.

  The opening 15 of the connecting collar 14 only needs to be filled with water in the water tank 11, but the foreign substance-containing article a does not enter the connecting collar 14, and is large enough to allow a small, low specific gravity foreign substance to enter the connecting collar 14. This is preferable from the viewpoint of removing only small and low specific gravity foreign matter. Further, the shape of the opening 15 may be any of a square shape, a circular shape, a slit shape, and the like.

  A plurality of chambers may be formed inside the water tank 11 by providing partition walls as necessary. As such a partition, the horizontal partition 16 which divides the water tank 11 into two upper and lower water tank parts 11a and 11b is mention | raise | lifted, for example. Thereby, the inside of the water tank 11 is divided into two parts, an upper water tank part (hereinafter referred to as “upper water tank part”) 11a and a lower water tank part (hereinafter referred to as “sewer tank part”) 11b. . At this time, the horizontal partition wall 16 is preferably provided with holes or the like so that the water in the water tank 11 can move freely.

  When the horizontal partition wall 16 is provided to form the upper water tank portion 11a and the lower water tank portion 11b, the foreign substance-containing article a introduced from the upper side of the water tank 11 moves in the upper water tank portion 11a. And as shown in FIG.1 and FIG.2, the bubbling apparatus 23 is attached to the sewage tank part 11b, and air is spouted upwards. The foreign-material-containing article a introduced from the article introduction end is bubbled in water by the bubbling device 23 and washed. Thereby, foreign materials, such as a small-sized low specific gravity foreign material and the foreign material c with larger specific gravity than water, can be isolate | separated from the foreign material containing article a. And the foreign material c with larger specific gravity than water sinks below, and moves to the sewer part 11b. For this reason, by dividing the inside of the water tank 11 into the upper water tank part 11a and the sewage tank part 11b, it is possible to separate at least the foreign substance c having a specific gravity greater than that of the water from the foreign substance-containing article a. In addition, a small low specific gravity foreign substance may also move to the sewer tank part 11b by the water flow produced by bubbling.

  The number of bubbling devices 23 provided is not limited to three as shown in FIG. 1 and FIG. 2, but may be one or two depending on the type of foreign matter-containing article a to be input, the type of foreign matter, and the amount of foreign matter attached. There may be four or more. Further, among the bubbling devices 23, the bubbling device 23 closest to the article input end portion needs to be bubbled in order to separate the foreign matters from the foreign matter-containing article a. Depending on the type and amount of the contained article a, the amount of foreign matter attached, etc., bubbling may be performed or bubbling may be stopped as necessary.

  Next, the sewage tank portion 11b is provided with a foreign material collecting cone 17 having an opening at the bottom as necessary. A pipe 18 communicating with the outside of the water tank 11 is attached to the top of the cone 17. The pipe 18 is closed by an opening / closing means (not shown) such as a valve. When the outlet of the pipe 18 is opened, the outlet of the pipe 18 is disposed below the water surface in the water tank 11. The water inside the cone 17 is led out through the pipe 18. At this time, the water around the cone 17 is drawn into the cone 17 and led to the outside. At this time, foreign matter such as a small, low-specific gravity foreign matter c or a foreign matter c having a higher specific gravity than water is also present. At the same time, it is led out and removed out of the water tank 11.

  By the way, as shown in FIG.1 and FIG.2, the bubbling apparatus 23 and the cone-shaped body 17 are provided in the sewage tank part 11b, but this sewage tank part 11b is divided into some, and a bubbling apparatus is provided in each of the small water tank parts. 23 and the cone 17 may be stored separately. In this way, the bubbling part and the foreign substance recovery part can be separated. In this case, the small water tank section is preferably provided in series from the article input end portion to the article take-out end portion of the water tank 11. Moreover, it is preferable that the partition which divides each small water tank part does not have a hole etc. so that water may not enter and exit. Thereby, each water tank part becomes independent and it becomes possible to lead out the foreign material c whose specific gravity is larger than the water which entered each water tank part from the cone-shaped body 17 more reliably.

  Moreover, the water injection apparatus 19 which injects water toward the water surface of the said water tank 11 can be provided in the goods insertion end part side of said connection collar part 14 as needed. As a result, as shown in FIG. 4, the foreign substance-containing article a (or article b) floating on the water surface can be pushed into the water, and the foreign substance-containing article a (or article b) can be prevented from being caught by the connecting collar 14.

  As shown in FIG. 1 and FIG. 2, the water injection device 19 is provided in accordance with the number of the connecting collars 14 so that the foreign substance-containing article a (or article b) is caught by the connecting collar 14. This is preferable because it can be prevented.

  If necessary, as shown in FIG. 5, a water wheel 21 for pushing down the water of the surface layer of the water tank 11 downward can be provided on the article input end side of the connecting collar 14. As a result, the foreign object-containing article a (or article b) floating on the water surface can be pushed into the water, and the foreign substance-containing article a (or article b) can be prevented from being caught by the connecting collar 14.

  The number of the water turbines 21 is not limited as long as it is provided on the article input end side of the water tank 11 and on the article input end side of the connecting collar 14.

  By the way, when the water injection device 19 and the water wheel 21 are provided, the small and low specific gravity foreign matter separated by the bubbling device 23 is pushed into the water at one end, but since it has a low specific gravity, it immediately floats on the water surface. . For this reason, unlike the foreign-material-containing article a (or article b), the small low-specific gravity foreign substance enters the inside through the opening 15 of the connecting collar part 14, and the small low-specific gravity foreign substance that enters the connecting collar part 14 is Excluded outside the water tank 11.

  In addition, when using the said water injection apparatus 19 and the water wheel 21 together, there is no restriction | limiting in the order, However, It is preferable to provide the water wheel 21 between the water injection apparatus 19 and the connection collar part 14. FIG. The water-injecting device 19 can push the foreign object-containing article a (or article b) into the water a little, and then push it deeper into the water with the water wheel 21, so that the foreign substance-containing article a (or article b) can be efficiently put into the water. This is because it can be pushed in.

Next, the operation of the foreign matter removing apparatus according to the present invention will be described using the apparatus shown in FIGS.
First, water is stored in the water tank 11. At this time, it is preferable that the water surface is held above the bottom surface of the connecting collar 14 and at the position of the opening 15 of the connecting collar 14 or near the lower position. If the water surface is below the bottom surface of the connecting collar 14, there is a risk that the efficiency of removing the small and low specific gravity foreign matter at the connecting collar 14 may be reduced, while the water surface is slightly above the opening 15 of the connecting collar 14. However, if it is too high, the water in the water tank 11 flows unconditionally to the connecting collar part 14 and the collar part 12, and the amount of water supplied into the water tank 11 increases.

  Moreover, while opening the sluice 22, water is supplied from the water supply part 10 so that the water surface of the water tank 11 may hold | maintain said range. Thereby, about the water of the water tank 11, especially the water of surface layer, the flow from the articles | goods injection | throwing-in edge part of the water tank 11 to an article | item taking-out edge part can be formed. What is necessary is just to adjust suitably the grade which the sluice 22 opens, according to the grade of the flow of the water of the water tank 11, the kind of articles | goods which comprise the foreign material containing goods a, and the kind and quantity of the foreign substances contained in the foreign material containing goods a.

  Next, the foreign object-containing article a is introduced into the article input end of the water tank 11 and air is ejected from the bubbling device 23. Thereby, the foreign material containing article a can be bubbled and the foreign material adhering to this can be separated. The article b from which the foreign matter has been removed flows toward the article take-out end portion according to the flow of water, is collected by the conveyor 13, and is collected by the article collection unit 26. At this time, if there is the water injection device 19 or the water wheel 21, the foreign object-containing article a (or article b) is pushed into the water by these, and the connecting rod provided immediately after the water injection device 19 or the water wheel 21. Colliding with the part 14 can be avoided.

  On the other hand, of the separated foreign matter, the foreign matter c having a specific gravity greater than that of the water settles below the water tank 11, is sucked up from the cone 17, and is collected in the collection tank 24 via the pipe 18. The In the collection tank 24, foreign substances are separated and removed by a separation device such as a net, and the remaining water is collected in the collection tank 24. Then, this water is sent to the water supply unit 10 and returned to the water tank 11.

  In addition, among the separated foreign substances, small and low specific gravity foreign substances float on the water surface. When the water injection device 19 and the water wheel 21 are provided, a small low specific gravity foreign substance is pushed into the water together with the foreign substance-containing article a (or article b). Floats up. For this reason, this small and low specific gravity foreign substance enters the inside of the connecting collar 14 from the opening 15 of the connecting collar 14 and is sent to the collar 12. The two troughs 12 are connected to a recovery trough 25 along the edge of the water tank 11 on the article take-out end side, and the recovery trough 25 is connected to the separation device of the recovery trough 24. Has been. For this reason, the water and small, low specific gravity foreign matter that have entered the connecting collar 14 are first separated and removed by the separation device of the recovery tank 24, and the remaining water is recovered in the recovery tank 24. The Then, this water is sent to the water supply unit 10 and returned to the water tank 11.

  The recovery dredge 25 is provided along the edge of the water tank 11 on the article take-out end side, so that when the sluice 22 is opened, the flowing water enters the recovery dredge 25 and the recovery tank 24 is collected.
