Description

  The present invention relates to a used oil filtration device used in fryer, tempura pan, and the like.

  When cooking fries and tempura using edible oil, fryer with cooking tank that can cook a large amount at once, or tempura pan that cooks a small amount such as for home use There is. For example, the oil stored in the fryer cooking tank deteriorates due to the generation of impurities such as fried residue (hereinafter referred to as residue) generated during cooking and the oxidation of the oil. used. At that time, the used oil may be reused by removing the residue by filtering the used oil. However, the oxidized oil could not be sufficiently regenerated by simply filtering the residue. In recent years, therefore, it has been practiced to reuse the oil by introducing an adsorbent into the used oil to adsorb impurities and oxides and then filtering.

  When filtering the oil used in the fryer, a filtration device using a filter is used. For example, in the following Patent Document 1, a filtration device is installed and used above a waste oil tank disposed in a lower part of a fryer. Further, Patent Document 2 discloses that the filtered oil is reused as it is by putting the adsorbent into a container in which the used oil is collected and filtering it above the cooking tank.

Japanese Patent Laid-Open No. 09-075237 JP 2010-065077 A Japanese Utility Model Publication No. 06-041645

  However, the filtration device described in Patent Document 1 does not use an adsorbent and simply removes the residue by filtration. Therefore, even if the filtered oil is reused, the oil is in an oxidized state, so that it is difficult to use for a long time. Moreover, in this filtration apparatus, since a sheet-like filter is installed between the filter net (cage member) and the filter cover, the filtration is performed only with the sheet-like filter. Here, although the filtration rate of the oil which does not contain an adsorbent is fast, the oil into which the adsorbent is added has fine particles, and thus the filtration rate is reduced.

  Therefore, in the filtering device using a sheet-like filter as disclosed in Patent Document 1, if the oil into which the adsorbent is introduced is filtered and filtered, the oil in the filtering device may become full during the filtration. . For this reason, it is necessary to perform the operation of injecting oil into the filtration device in a plurality of times or to reduce the injection speed. Thus, if the oil into which the adsorbent is added to the filtering device of Patent Document 1 is filtered, the filtering operation takes time and effort. Although it is conceivable to increase the volume of the filtration device, an increase in the size of the filtration device is not preferable because a large space is required in the upper part of the waste oil tank and the fryer is increased in size.

  On the other hand, in the filtration method described in Patent Document 2, filtration takes time because the adsorbent introduced into the container in which the oil has been collected is precipitated after stirring and then filtered. In addition, after filtering the oil, it is necessary to remove the adsorbent that has settled in the container, and workability is not good. Here, in patent document 2, the filtration part has installed the filter in the spout of a funnel can or the oil drain port of a fryer. When filtration is performed after the adsorbent has been precipitated, such a filtration unit is sufficient. However, when filtering oil containing the adsorbent, the filter area is narrow, so the filtration takes time. It will take.

  Furthermore, there are various types of fryer depending on the volume of oil to be used. Even if the capacity is the same, the size of the cooking tank in which the oil is stored varies depending on the manufacturer of the fryer. Therefore, in order to filter above the cooking tank, it is necessary to prepare a filtering device suitable for the size of the cooking tank of the target fryer, and versatility as a filtering device is not sufficient.

  Therefore, in view of the above circumstances, the present invention has a technical problem of providing a versatile filtration device that can prevent an increase in the labor of filtration work and can perform filtration in a short time. To do.

  The filtration device of the present invention for solving the above-mentioned problem is a filtration device for filtering used oil, and has a filter having an accommodating portion capable of accommodating oil therein, the same shape as the filter, and the filter A filter holding member that can be mounted along the inside, and a support portion that can support the filter holding member and has a displaceable abutting portion that abuts a storage tank in which oil is stored. The support portion that supports the filter holding member is displaced above the storage tank by displacing the abutment portion to perform filtration by being installed above the storage tank.

  According to such a configuration, the filter and the filter holding member have the same shape, and the filter can be mounted along the inside of the filter holding member, so that the filter is held in close contact with the filter holding member. be able to. Thereby, since it can filter not only from the bottom part of a filter but from a side part, the time concerning filtration can be shortened. Therefore, it is not necessary to inject oil into the filter housing portion in a plurality of times, and no labor is required. In addition, since the abutment portion of the support portion can be displaced, the abutment portion is displaced according to the size of the storage tank, so that the abutment portion abuts on the storage tank regardless of the size of the storage tank and is filtered. The apparatus can be installed above the storage tank. Thereby, the versatility of a filtration apparatus becomes high. Note that the filter and the filter holding member have the same shape means that when oil is stored in the filter storage portion, there is no overlapping portion of the filter and the filter is held by being along the inside of the filter holding member. It means that.

  Further, the support portion is configured by a frame member in which two frame bodies are connected to be stretchable, and the frame body connects two parallel strut portions facing each other and ends of each strut portion, and each A contact portion formed orthogonal to the support column, a mounting unit that connects the other ends of the support columns, and is formed orthogonal to each support column to mount and support the filter holding member; And a slide tube that slidably supports the struts of the two frame members arranged opposite to each other, and the two frame members may be connected by the slide tube.

  Here, it is disclosed in Japanese Utility Model Laid-Open No. 06-041645 (Patent Document 3) that a cage member which is an example of the filter holding member of the present invention is supported by a telescopic frame member. However, in Patent Document 3, a plurality of parts such as a supporting bar, a locking plate, and a receiving frame are required. Therefore, by configuring the frame member as described above, the frame member can be configured simply by connecting the two frame bodies by the slide tube, so that the number of manufacturing parts can be reduced and the cost can be reduced. Can be manufactured.

  As described above, according to the present invention, it is possible to provide a versatile filtration apparatus that can prevent an increase in the labor of the filtration work and can efficiently perform the filtration in a short time. .

It is a disassembled perspective view of the filtration apparatus concerning one Embodiment of this invention. It is an enlarged view which shows the latching | locking part of the frame part in the filtration tank shown in FIG. It is a figure which shows the use condition at the time of mounting | wearing a fryer with the filtration apparatus of FIG. It is sectional drawing of the principal part in FIG. It is sectional drawing of the principal part which shows the other use condition at the time of mounting | wearing a fryer with the filtration apparatus shown in FIG.

  Hereinafter, one embodiment of a filtration device concerning the present invention is described based on a drawing.

  As shown in FIG. 1, the filtering device 1 of the present invention places a filter 10 that can contain oil therein, a cage member 20 as a filter support member to which the filter 10 can be mounted, and a cage member 20. It is comprised from the frame member 30 as an example of the support part which can be supported by.

  The filter 10 has a bag shape with an open top, and in the present embodiment, has a substantially rectangular parallelepiped shape that can be folded. Reference numeral 11 denotes an oil container. The filter 10 is formed of filter paper made mainly of pulp, and can filter the adsorbent that is put into used oil. In addition, you may form the filter 10 with the nonwoven fabric, net | network fabric, etc. by a synthetic fiber, a natural fiber, or its mixture. Furthermore, in this embodiment, the height dimension of the filter 10 is larger than the height dimension of the cage member 20, and the accommodating part 11 of the filter 10 is stored in the cooking tank 41 (refer FIG. 3) of the fryer 40. It has a volume that can accommodate the amount of oil.

  The cage member 20 has a box shape with an upper portion opened. In the present embodiment, a substantially rectangular parallelepiped shape including a rectangular bottom surface 21 and a side surface 22 extending upward from an edge of the bottom surface 21 is formed. Moreover, it is the same shape as the filter 10 and the filter 10 is mounted along the inside of the cage member 20. In the present embodiment, each surface of the cage member 20 is formed by knitting a stainless steel wire into a mesh shape. The mesh has a roughness through which the residue from the use of the flyer 40 (see FIG. 3) passes. Further, a wire rod is disposed on the upper edge 23 of the cage member 20, and a handle 24 that is used when lifting the cage member 20 is formed on the upper edge 23 on the opposite long side.

  As shown in FIG. 1, the frame member 30 includes two frame bodies 31 and a slide tube 35 that slidably connects them. The frame 31 is formed of a wire having rigidity that can support the cage member 20 in a state where oil is accommodated in the accommodating portion 11 of the filter 10. In the present embodiment, the two frame bodies 31 have the same shape, and each frame body 31 connects two parallel support column portions 32 facing each other and one end of each support column portion 32, and each support column. The substantially rectangular shape which has the contact part 33 formed orthogonally to the part 32, the other end of each support | pillar part 32, and the mounting part 34 formed orthogonally to each support | pillar part 32 Make. The abutting portion 33 abuts on the side wall 44 (see FIG. 3) when the frame 31 is installed in the cooking tank 41 of the fryer 40, and the cage member 20 is placed on the placing portion 34. Further, both the contact portion 33 and the placement portion 34 are formed to protrude downward from the support portion 32, and the placement portion 34 is formed to protrude downward from the contact portion 33.

  As shown in FIG. 2, the slide tube 35 has the cylindrical portions 36 arranged in parallel, and holds the column portions 32 of the frame 31 slidably inside the cylindrical portions 36 (see FIG. 2). At this time, the two frame bodies 31 are arranged such that a part of the frame body 31 overlaps and the placement portion 34 faces the sliding direction (see FIG. 1). Further, the slide tube 35 has a length shorter than the width of the cage member 20 (the length in the short side direction shown in FIG. 1). As shown in FIG. In order not to come off, the mounting portion 34 functions as a stopper for retaining. Thus, the frame member 30 can be expanded and contracted by sliding the frame 31, and the contact portion 33 is displaced as the frame member 30 expands and contracts.

  In FIG. 3, the fryer 40 which can install the filtration apparatus 1 is shown. The fryer 40 is provided with a cooking tank 41 as an example of a storage tank in which edible oil is heated to an appropriate temperature for cooking and in which oil is stored, and in the lower part, a space S between the leg portions 42 facing each other. Is formed. In this space S, a collection tank 50 that stores oil discharged from the cooking tank 41 is arranged. Further, the filtration device 1 is installed above the cooking tank 41.

  In FIG. 4, sectional drawing of the principal part in the state in which the filtration apparatus 1 was installed is shown typically. The cooking tank 41 can store edible oil by the bottom 43 and the side wall 44, and as shown in FIG. 4, a heater 45 provided below the center of the cooking tank 41, and a net part disposed above the heater 45. 46, provided at the bottom 43 of the cooking tank, and a discharge port 47 for discharging oil. The heater 45 is a heat source that heats the oil stored in the cooking tub 41, and heats the oil in the cooking tub 41 to a predetermined temperature and maintains it at an appropriate temperature under the control of a control unit (not shown). The net part 46 is a metal net, and is arranged on the upper part of the heater 45 so that the cooked product to be cooked does not come into contact with the heater 45 to support the cooked product. Residue such as fried residue generated during cooking passes through the net 46 and accumulates on the bottom 43 below the cooking tank 41. Moreover, the bottom part 43 of the cooking tank 41 is inclined, and a discharge port 47 for discharging the oil in the cooking tank 41 is provided at the lowermost part thereof.

  The filtration device 1 is installed suspended on the left and right side walls 44 of the cooking tank 41 of the fryer 40. Specifically, the frame member 30 is adjusted to the dimension between the both side walls 44 of the cooking tank 41, and the abutting portion 33 is brought into contact with the both side walls 44 of the cooking tank 41. The cage member 20 to which the filter 10 is attached is placed on the placement portion 34 of the frame member 30. At this time, as shown in FIG. 4, the bottom surface 21 of the cage member 20 is at a position lower than the upper edge of the side wall 44 of the cooking tank 41, and the oil level L <b> 1 in the cooking tank 41 (shown by a dashed line in FIG. 4). ) To be located above.

  Then, the operation | movement of the filtration operation | work using the filtration apparatus 1 concerning this invention is demonstrated. The operator adjusts the frame member 30 in accordance with the width dimension of the cooking tank 41 of the fryer 40 and installs it above the left and right side walls 44 of the cooking tank 41. Then, the filter 10 is mounted along the inner wall of the cage member 20, and the cage member 20 in that state is placed on the placement portion 34 of the frame member 30. In this embodiment, since the height dimension of the filter 10 is larger than the height dimension of the cage member 20, the surplus portion of the upper part of the filter 10 protruding from the cage member 20 is folded outward (see FIG. 3). .

  On the other hand, used oil stored in the cooking tank 41 of the fryer 40 is transferred from the outlet 47 of the cooking tank 41 to the collection tank 50 by operating a valve (not shown). Here, for example, a large residue in the oil may be removed by installing a filter net or the like above the collection tank 50. In addition, whichever of the order of the installation of the frame member 30 to the fryer 40 and the transfer operation of the oil from the cooking tank 41 may be performed first. Moreover, you may clean the cooking tank 41 of the fryer 40 at this time, and in that case, after washing | cleaning the cooking tank 41, after wiping off moisture, the filtration apparatus 1 is installed.

  Next, the adsorbent is put into the collection tank 50 in which used oil is stored. As the adsorbent, silicon dioxide, (active) clay, one obtained by adding an alkali component such as magnesium oxide to this, powdered activated carbon or the like can be used. As soon as the adsorbent is put into the recovery tank 50, since oxides and impurities in the oil are adsorbed to the adsorbent, the adsorbent is stirred so as to reach the entire recovery tank 50. Immediately, oil can be injected into the accommodating portion 11 of the filter 10 of the filtration device 1. In order to prevent scattering when the adsorbent is charged, the used oil may be transferred to the recovery tank 50 after the adsorbent has been previously input to the recovery tank 50. Further, the adsorbent may be put in advance in the accommodating portion 11 of the filter 10 into which the oil in the recovery tank 50 is injected.

  Thereafter, the oil in the collection tank 50 is poured into the filtration device 1 together with the adsorbent. The adsorbent is filtered by the filter 10 of the filtering device 1, and the filtered oil flows into the cooking tank 41 of the fryer 40 and is stored. Here, since the adsorbent that has adsorbed the impurities has a large specific gravity, the adsorbent is precipitated at the bottom of the filter 10. Therefore, although the filtration rate is reduced near the bottom, since filtration can be performed also from the side surface region of the filter 10, it is possible to prevent a decrease in the filtration rate as a whole.

  When the filtration is completed, the filter 10 is removed from the cage member 20 of the filtration device 1, and the filtered adsorbent residue is discarded. And the oil stored in the cooking tank 41 can be used as it is by removing the cage member 20 and the frame member 30. In addition, in order to make the oil in the cooking tank 41 into a predetermined amount, you may add new oil as needed.

  Thus, in order to remove the impurities from the oil and regenerate, in addition to the conventional work of transferring the used oil to the recovery tank 50 and injecting the oil in the recovery tank 50 into the cooking tank 41. , Installing the filtration device 1 above the cooking tank 41, and introducing the adsorbent into the collection tank 50 (before or after changing the oil) or the container 11 of the filter 10, Since only stirring work is required, it does not take time. Moreover, in the filtration apparatus 1, since it can filter not only from the bottom face of the filter 10 but from a side surface, it becomes possible to filter efficiently in a short time. Furthermore, since the filtration apparatus 1 can be installed by expanding and contracting the frame member 30 according to the size of the cooking tank 41, for example, the filter 10 and the cage member 20 corresponding to the volume of the cooking tank 41 may be prepared. Can increase the sex. In addition, since the frame member 30 is composed of two frame bodies 31 having the same shape and a slide tube 35 for slidably connecting them, the frame member 30 can be easily manufactured with a small number of parts, and the filtration device can be made inexpensive. Can be provided.

  In the present embodiment, the filter 10 has the same shape as the cage member 20, and the size in the vertical direction and the lateral direction is slightly smaller than that of the cage member 20. Here, if the size of the filter 10 in the vertical direction and the horizontal direction is too larger than the cage member 20, it is necessary to bend and attach a part of the filter 10, so that the filter 10 is overlapped at the bent portion. , Filtration takes time. Further, if the filter 10 is too small than the cage member 20, when the oil is transferred to the accommodating portion 11 of the filter 10, the cage member 20 cannot sufficiently hold the filter 10, and the oil leaks from the filter 10. There is a fear. This is the same even when the shapes of the filter 10 and the cage member 20 are different. Therefore, as described above, these problems can be prevented by making the filter 10 and the cage member 20 have the same shape and are in close contact with each other.

  Further, the height dimension of the filter 10 is larger than the height dimension of the cage member 20. For this reason, when the filter 10 is mounted on the cage member 20, the upper surplus portion protruding from the cage member 20 is folded outward. Thereby, the filter 10 can be fixed to the cage member 20, and the filter 10 can be prevented from slipping off from the cage member 20 when the oil is transferred to the accommodating portion 11 of the filter 10.

  Furthermore, it is preferable that the filter 10 and the cage member 20 have a volume capable of storing the oil in the cooking tank 41 at a time. In addition, when inject | pouring oil from the collection tank 50 to the cooking tank 41, since filtration is started simultaneously with injection | pouring, it is not limited to being larger than the volume of the cooking tank 41.

  Here, the injection of oil from the collection tank 50 to the filtration device 1 may be performed by pumping up using a pump (not shown). This eliminates the need to lift the collection tank 50 when injecting oil into the filter 10 of the filtration device 1, so even the large fryer 40 using a large volume of oil is used with the filtration device 1. It is possible to perform filtration. When the oil in the recovery tank 50 is pumped up and filtered, the adsorbent is put in the filter 10 in advance to prevent clogging of the pump and simultaneously with the injection by the pump. It is preferable to filter the mixture after stirring.

  The filter 10 and the cage member 20 of the filtration device 1 can be appropriately prepared according to the type of the flyer 40. For example, it is preferable to prepare a plurality of types according to the difference in capacity in addition to a narrow type and a wide type in the width direction. Here, even if the fryer 40 has the same capacity, the size of the cooking tank 41 varies depending on the manufacturer. Therefore, by preparing the types of the filter 10 and the cage member 20 according to the capacity, the small size difference can be adjusted by the expansion and contraction of the frame member 30, thereby increasing versatility.

  Further, the cage member 20 may be immersed in the cooking tank 41 when the fryer 40 is used. Thereby, the basket member 20 can be used as an oil draining container of a cooked product during cooking without exchanging oil. Here, the vertical and horizontal dimensions of the bottom surface 21 of the cage member 20 are smaller than the vertical and horizontal dimensions of the cooking tank 41 of the fryer 40 (see FIG. 4). Therefore, the bottom surface 21 of the basket member 20 can be immersed in the cooking tank 41 until it contacts the net 46 of the cooking tank 41. Moreover, it is preferable to make the height dimension of the cage member 20 larger than the height dimension (indicated by H in FIG. 4) from the mesh portion 46 to the oil surface L1. In addition, since the oil in the cooking tank 41 is stored also below the net | network part 46, it is preferable that the height dimension of the cage member 20 is made sufficiently larger than said H. Thereby, the volume which can accommodate the oil in the cooking tank 41 in the filter 10 is securable.

  Depending on the type of the fryer 40, there is a type in which an inclined plate is provided on the wall of the cooking tank 41 in order to prevent oil from splashing when the cooked product is put into the cooking tank 41 during cooking. In that case, an inclined region may be formed on the filter 10 of the filtration device 1 and the bottom surface 21 of the cage member 20. Moreover, it is good also as a shape which formed the level | step difference in a part of bottom face 21 so that an inclination board may be escaped.

  As another embodiment of the filtration device 1 according to the present invention, the filtration device 1 may be installed above the collection tank 50 disposed in the space S below the fryer 40. Specifically, as shown in FIG. 5, the frame member 30 is installed by suspending the contact portion 33 against a side wall portion of a collection tank 50 as another example of the oil storage tank. Also in this case, the width of the frame member 30 is adjusted according to the dimension between the side walls of the collection tank 50. Further, on the mounting portion 34 of the frame member 30, the bottom surface 21 of the cage member 20 is above the oil level L2 (shown by a one-dot chain line in FIG. 5) of the oil stored in the collection tank 50. The cage member 20 to which the filter 10 is attached is placed so as to be positioned. In the present embodiment, the handle 24 of the cage member 20 in the above embodiment is omitted. For example, the handle may be provided on the upper edge 23 of the cage member 20 on the near side and the far side in the drawing and in a direction parallel to the bottom surface.

  In the present embodiment, when the used oil is filtered, the adsorbent is put into the cooking tank 41 and stirred, and then the oil is discharged from the discharge port 47. The oil discharged from the discharge port 47 is stored in the storage portion 11 of the filter 10 of the cage member 20. Then, the oil obtained by filtering the adsorbent and residue in the oil by the filter 10 is stored in the recovery tank 50. The cooking tank 41 is preferably cleaned so that no adsorbent remains. Thus, the oil regenerated by being filtered by the filtration device 1 is poured into the cooking tank 41 and used again. At this time, when injecting oil from the collection tank 50 to the cooking tank 41, the collection tank 50 may be taken out and an injection operation may be performed. Similarly to the above, a pump (not shown) may be used.

  In the present embodiment, since the filter 10 is mounted along the inside of the cage member 20, filtration can be performed from the bottom and side regions of the filter 10, and the filtration speed can be increased. Therefore, even if the filtration apparatus 1 is installed above the collection tank 50 and the oil into which the adsorbent is added is filtered, the filtration can be sufficiently performed. Further, by filtering the used oil below the fryer 40, the temperature of the oil is lowered during the filtration, so that it is not necessary to transfer the high temperature oil from the recovery tank 50 to the cooking tank 41. Therefore, it is possible to improve the labor of the worker.

  Here, depending on the space S below the fryer 40 and the volume and shape of the collection tank 50, there may be a case where a sufficient space for installing the filtration device 1 cannot be secured. In that case, you may form the filtration apparatus 1 and the collection tank 50 newly, for example. Moreover, you may mount | wear with the inside of the collection tank 50 so that the lower part of the cage member 20 of the filtration apparatus 1 may be included. At this time, during the filtering operation, the recovery tank 50 is taken out in a state where the oil is stored in the accommodating portion 11 of the filter 10, and the basket member 20 with the filter 10 attached is pulled up from the recovery tank 50 to perform the remaining filtration. It may be. In this case, for example, the frame member 30 is formed in a concave shape, and a first support part that supports the bottom surface of the cage member 20 to be positioned inside the collection tank 50, and the cage member 20 above the collection tank 50 are provided. It is preferable to provide the 2nd support part to install. The support part of the frame member 30 may be changed by extending and contracting the frame member 30, and the second support part may be provided so as to be able to appear and retract with respect to the frame member 30.

  In addition, even if the filtration device 1 is installed above the collection tank 50, if the installation space for the filtration device 1 cannot be secured sufficiently, the oil is discharged at a lower discharge speed from the discharge port 47 of the cooking tank 41. May be. Specifically, for example, it is preferable to set the discharge rate to be the same as the filtration rate after the oil is stored to some extent in the accommodating portion 11 of the filter 10. Thereby, oil can be prevented from overflowing from the filter 10 of the filtration device 1. Further, in the above example, the adsorbent may be put in the filter 10 in advance.

  In the above embodiment, the shape of the cage member 20 is a substantially rectangular parallelepiped. However, the shape is not limited to this, and the shape may be a cube shape or a columnar shape, and the bottom surface 21 may be a convex curved surface. May be. In addition, it is preferable to make the cage member 20 and the filter 10 into the same shape regardless of the shape. Further, the filter holding member is not limited to the cage member 20 formed of a wire knitted in a net shape, and is formed of a rigid metal wire as long as the filter 10 containing oil can be sufficiently held. It may be a filter holding member. Furthermore, the filter holding member may be formed of resin, cloth, paper, or the like.

  Moreover, a frame member is not restricted to the form which combined the frame body of the same shape. Different shapes of frame bodies may be combined. For example, one of the frame bodies may be extended to form a handle.

  Furthermore, in the said embodiment, although the example which made the support part which supports a filter holding member the frame member of another member was given, it is not restricted to this, Even if a filter holding member and a support part are integrated. Good. For example, a part of the filter holding member may be an extensible frame member, and the filter member may be installed above the storage tank in which oil is stored by extending the frame member. Moreover, you may form a movable hook etc. in a filter holding member as a support part which has a contact part to a storage tank. This makes it possible to provide a filtration device with a reduced number of parts.

  Although the embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made without departing from the gist of the present invention. Although the above-mentioned filtration apparatus showed the example installed in a fryer, you may use when filtering a small amount of oils, such as a domestic tempura pan and an oil pot. In that case, for example, the filter holding member and the frame member are made of paper and formed integrally with the filter, and are installed on the upper edge of the tempura pan or above the net for removing the frying residue from the oil pot. Or you may.
