DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oil filter for removing suspended matter and dirt from edible oil and filtering the same, and an oil storage container usable for the oil filter.

[0002]

2. Description of the Related Art When cooking fried foods such as tempura and fried food in the home diet, if the amount of fried foods to be made at one time is not so large, floating materials such as heavenly chips and burnt wastes are removed from paper. In many cases, the oil is filtered and reused. Recently, an oil filtration device equipped with a collection container made of stainless steel or the like and a filter unit also made of stainless steel net or the like is commercially available and widely used in homes. When filtering and recovering oil using such a device, first, a filter net is set in a recovery container, and a filter paper is placed here and used oil is poured. At this time, the suspended matter is filtered off by the paper, and the oil that has passed through the paper and the filtering net is recovered in the recovery container. On the other hand, when the collected oil is reused, the collection container is tilted and the oil is poured again into a pot or the like. In this case, in order to easily pour out the oil, a part of the peripheral edge of the opening of the collection container is often protruded into, for example, a beak shape to form an oil pouring portion.

[0003]

In the above conventional oil filter, the oil is poured out by tilting the collecting container, and when the container is returned to the original position, the oil is discharged from the tip of the oil discharging portion to the outer surface of the container. It is easy for anyone to get rid of it, and there is a problem that not only the container, but also the table on which the container is placed and the hands of the people who handle the container become dirty. In addition, the oiled container is slippery, and a trouble such as dropping the container and spilling oil is also likely to occur. On the other hand, oil filtration can be performed smoothly in a high temperature state where the viscosity of the oil is low, but if the recovery container is made of metal such as stainless steel, the container becomes hot immediately after oil recovery. There is a problem that becomes difficult to handle. In this case, there is a method of inserting a heat insulating material into the wall of the container, but this makes the container expensive.

When the oil is poured out, the filter must be removed, but it is difficult to pour out the oil while holding the filter. Must be in place. In this case, there is a problem that the filter portion becomes dirty because oil is attached thereto, and it is troublesome to separately prepare a saucer or the like for placing the filter, or to lay paper or the like. .

[0005] A first object of the present invention is to provide an oil filtering device having a structure that prevents oil from dripping from the tip of an oil discharging portion to the outer surface of a collecting container, and an oil container that can be used therein. It is in. Another object of the present invention is to provide an inexpensive oil filtration device which is difficult to raise the temperature of a container when high-temperature oil is recovered, and which is easy to handle, and an oil container which can be used for the device. . Further, the third problem is that when the oil is poured out of the container, the removed filter portion can be appropriately stored, and the place where the filter portion is soiled by the oil adhering to the filter portion may be contaminated. It is an object of the present invention to provide an oil filtering device without the above.

[0006]

Means for Solving the Problems and Functions / Effects In order to solve the first problem, the oil filtration device of the present invention is characterized in that it is configured as follows. That is, the oil filtration device has an opening on the upper surface side and the inside is an oil storage space, and an oil discharging portion for discharging oil stored in the oil storage space is formed from the periphery of the opening. It has a container main body formed in a form protruding outward, and a filter receiving portion which is detachably attached to an opening of the container main body and has a liquid passage portion formed at least at the bottom thereof. By setting a filter in the filter receiving portion and pouring oil to be filtered, while filtering out solids in the oil by the filter, the oil passing through the filter is passed through the liquid passage portion of the filter receiving portion. Through the container. Then, the oil discharging portion is more than the first overhanging portion so that a predetermined amount of gap is formed between the first overhanging portion located on the outer surface side of the container body and the first overhanging portion. Having a second overhang formed on the inside, wherein the first and second overhangs are
At least the upper edge position of the overhanging tip portion is set to be higher than the first overhang portion at the second overhang portion, and when the oil in the container body is poured out from the oil ejection portion, the second overhang portion has The oil dripping on the outer surface side is collected in the container main body through the gap formed between the first projecting portion and the oil.

That is, in the configuration of the present invention,
The oil ejection portion formed in the container main body for collecting the filtered oil has a structure in which the first and second overhanging portions are doubled through a gap, and the second overhanging position is located inside. The upper edge position of the overhanging tip portion of the portion is set higher than that of the first overhang portion located outside. When the container body is tilted, oil flows out in a narrowed form at the projecting tip of the second projecting portion by the oil spouting portion of the structure, but the projecting tip of the first projecting portion has a falling trajectory of the oil. Thus, the oil is retracted into the container body by an amount corresponding to the difference in height, and the oil flowing out is less likely to come into contact with the container. As a result, oil dripping is less likely to occur at the overhanging tip of the first overhang. On the other hand, oil dripping often occurs on the outer surface of the second overhang portion, but this dripping oil flows down into a gap between the first overhang portion and is collected by the container body. Therefore, oil dripping on the outer surface of the container body is extremely unlikely to occur, and the first object of the present invention is solved.

[0008] The height V of the upper edge position of the second overhanging portion at the overhanging tip position from the upper edge position of the first overhanging portion, and the overhanging edge position of the first overhanging portion and the second overhanging portion. The ratio V / H to the horizontal distance H between them is desirably set to 0.3 or more. When V / H is less than 0.3,
The oil that flows out from the overhanging tip of the second overhang is likely to come into contact with the first overhang and oil dripping is likely to occur. V / H is more desirably set to 0.4 or more.

Next, the container body may be made of a metal such as stainless steel, but the whole body including the first overhanging portion and the second overhanging portion can be constructed as an integral ceramic. Porcelain has a low thermal conductivity and a large heat capacity as compared with metal, so that when high-temperature oil is recovered, the temperature of the container is unlikely to rise, and handling is easy. In addition, by molding the raw material soil (for example, press molding of kneaded soil or slip casting using slurry), and drying and firing the same, it is possible to easily form an oil injection portion having a complex shape including a double overhang portion. Thus, the container body can be configured at low cost. That is, the second problem of the present invention is solved. When the container body is made of metal, one of the overhangs is formed integrally with the wall of the container body by sheet metal pressing or the like, and the other is formed by welding or screwing the container body. be able to.

Next, the above-mentioned gap is formed between the first overhanging portion and the second overhanging portion in the form of a groove with a bottom, and the groove-like portion constitutes at least a part of a dripping oil recovery passage. can do. In this case, an oil guide for guiding the dripping oil into the oil storage space of the container body can be formed at the end of the recovery passage. Thereby, the oil dripping on the outer surface of the second overhang portion is smoothly collected from the oil guide portion into the container body through the groove-shaped recovery passage. At this time, if the bottom surface of the recovery passage is set as an inclined surface in which, in the circumferential direction of the opening, the leading end side of the first or second overhanging portion is higher and the oil guide portion side is lower, the oil is inclined in the inclined direction. And the oil that flows down can be more smoothly collected.

In the container body, a first overhang portion is formed by partially projecting an outer peripheral portion of the container outward, and an inner surface of the peripheral portion of the opening has a predetermined depth from an upper edge of the opening. At the location, a step can be formed that projects inwardly along its circumferential direction. Further, on the upper surface of the step portion, at least a position corresponding to the first overhang portion is included, and an auxiliary wall portion is formed so as to rise upward along a part of the inner edge thereof. The portion corresponding to the first overhang may form a second overhang. In this case, a groove-shaped portion formed between the auxiliary wall portion and the peripheral portion of the opening of the container body including the first overhanging portion can be used as the collection passage. That is, the peripheral edge portion of the opening of the container body and the auxiliary wall portion, that is, the first overhanging portion and the second overhanging portion can be integrated via the upper surface of the step portion, and thus the entire container is formed of an integral ceramic as described above. In this case, the production of the molded article can be performed relatively easily. In this case, on the upper surface of the first step portion, a groove portion as an oil guide portion is opened to the step inner peripheral surface side along the width direction of the step portion upper surface outside the both end portions of the auxiliary wall portion in the circumferential direction. It can be formed as follows. The groove-shaped oil guide portion is easy to form, and the oil in the recovery passage can be reliably guided into the container body.

Next, the filter receiving portion is integrally formed with a filter receiving main body in the form of a container having a bottom having an opening on the upper surface side and extending outward along the periphery of the opening of the filter receiving main body. And the filter receiving main body is supported from below by the flange portion by the step formed on the container main body side in a state in which the filter receiving main body is housed inside from the opening of the container main body. Can be configured as Accordingly, the filter receiving portion is accommodated in the container main body, and the step provided for forming the recovery passage can be used for the support portion of the filter receiving portion, so that the entire oil filtering device can be made compact. .

The opening of the container body can be closed and opened by a lid. In this case, on the lower surface of the lid, a ridge portion is formed along the outer edge circumferential direction, and in a state where the lid closes the opening, the ridge portion is formed by the first overhang portion and the second overhang portion. It can be configured to engage with the inside of the opening of the container body while being located in the gap formed therebetween. That is, by forming the above-mentioned convex portion on the lid and engaging it with the opening of the container body, it is possible to prevent the lid mounted on the container body from sliding or rattling in the horizontal direction. it can. And since the said convex part is located in the said clearance gap, the interference with the 1st overhang part or the 2nd overhang part is avoided, and the sealing property of the lid with respect to a container main body is improved.

Next, at the center of the lower surface of the lid, a convex portion on the lid side can be formed projecting from the lower surface, and a concave portion on the receiving portion side is formed on the lower surface at the bottom of the filter receiving portion. be able to. Then, the filter receiving portion can be held on the lid in a state where the lid is removed from the container main body, and the filter receiving portion is turned upside down and the receiving portion side concave portion is fitted to the lid side convex portion. That is, when the oil collected or stored in the container body is poured out, the removed filter portion may be placed on the lid, and can be stably held by the engagement between the lid-side convex portion and the receiving-side concave portion. . Accordingly, there is no need to worry about soiling the storage location or the like due to the oil attached to the removed filter portion, and the third problem of the present invention can be solved.

In this case, a concave portion is formed on the upper surface of the lid at a position corresponding to the convex portion on the lid side, and a knob portion for attaching and detaching the lid to and from the container body is formed protruding from the bottom surface of the concave portion. be able to. That is, if the wall of the lid is formed so as to be recessed toward the lower surface, the lid-side protrusion can be easily formed, but in this case, a recess is necessarily formed on the upper surface of the lid. . Therefore, by making use of the recesses produced as by-products and forming the knob portion here, the lid can be easily attached and detached, and the knob portion does not protrude from the upper surface of the lid, so that the appearance is improved.

When the oil is filtered by the oil filtering device, a filter is set in the filter receiving portion, and the inorganic substance powder containing water is held in the filter above the filter itself. By pouring a high-temperature oil onto the powder, the oil can be purified by bringing the inorganic substance powder into contact with the oil. In this case, the filter filters out the inorganic substance powder for purification as well as the suspended matter in the oil.

According to this, by contacting the high-temperature oil with the inorganic substance powder containing water, the dirt substance contained in the oil can be captured by the inorganic substance powder and effectively removed and purified. it can. As the inorganic substance powder, it is preferable to use a powder which can contain water and is hardly decomposed or dissolved even when it comes into contact with high-temperature oil. Natural minerals containing water by incorporation into body particles or purified and powdered minerals, and artificially synthesized or powdered inorganic substances with a composition or structure similar to those minerals Can be used.

Of these, various clay minerals mainly composed of hydrous aluminum silicate and purified products thereof (hereinafter simply referred to as clay minerals) are particularly preferably used in the present invention. , Montmorillonite, bentonite, kaolinite, halloysite, pyrophyllite, sericite, chlorite, illite and the like, and purified products thereof can be used.
Further, plural kinds of various clay minerals can be used in combination. Further, synthetic inorganic substances having compositions or crystal structures similar to those of the above-mentioned various clay minerals can also be used. As such a synthetic inorganic substance, for example, synthetic smectite (for example, product name: Smecton, Kunimine Kogyo Co., Ltd.) is excellent in the adsorption performance of contaminants and can be suitably used in the present invention.

For example, in the case of edible oil, the oil is brought into contact with the above-mentioned inorganic substance powder in a high temperature state such as after use in cooking, and the oil whose temperature has dropped is heated in advance by a heater or the like. . The dirt components in the oil are physically or chemically adsorbed on the surface by contact with the powder particles, or are trapped by being taken in,
It will be removed from the oil. At this time, the moisture of the inorganic substance powder evaporates as steam due to the heat of the oil, and a large amount of steam bubbles are generated in the oil. When the air bubbles escape to the outside, the oil is vigorously stirred with the inorganic substance powder, so that the contact efficiency between the oil and the surface of the powder particles is enhanced, and the inorganic substance powder captures the contaminants, thereby purifying the oil. Will proceed promptly. In addition, dirt components that cannot be removed by the filter, such as odor components, are also removed neatly, and regeneration is possible even with heavily soiled oil, so that environmental pollution due to oil drips is not caused and is economical. . Here, the temperature of the oil is adjusted within a range in which the evaporation of the water contained in the powder sufficiently proceeds and the oil itself does not smoke or undergo thermal deterioration.
The temperature is adjusted to about 00 to 220 ° C, preferably about 130 to 200 ° C.

The amount of water contained in the inorganic substance powder is appropriately selected in consideration of the state and amount of dirt of the oil to be brought into contact, and for example, in the case of clay mineral, it is preferably about 3 to 15% by weight. desirable. If the water content is too small, the amount of water that evaporates is small, and the oil is not sufficiently stirred and thus purified. On the other hand, if the water content is too large, the relative content of the inorganic substance in the powder decreases, so that the efficiency of capturing the dirt substance decreases, and the amount of generated steam increases, which may cause problems such as oil scattering. Not preferred.

The lower limit of the particle size of the inorganic substance powder is, for example, when the powder is separated from oil by a filter or the like, a large amount of fine particles pass through the filter, or the sedimentation speed of the powder particles in the oil. Is set so that the separation efficiency of the oil and the powder does not decrease due to excessively small value. On the other hand, the upper limit of the particle size is within a range where the contact area between the particle surface and the oil does not become too small.
As a result, it is set within a range where the oil purification efficiency does not decrease.

Here, when a natural clay mineral is used, it is desirable to purify and remove unnecessary components as much as possible. When the above-mentioned unnecessary components cannot be sufficiently removed by a usual method, it is also effective to use a synthetic substance containing no such components instead of natural minerals.

On the other hand, besides clay minerals, various inorganic substance powders such as activated clay, diatomaceous earth and activated alumina can be used. Further, by using them in a mixture with a clay mineral, a greater purification effect may be obtained. For example, by mixing purified smectite or bentonite with a certain amount of activated clay and diatomaceous earth, it is possible to obtain an inorganic substance powder having more excellent oil purification ability.

Various additives can be added to the inorganic substance powder as needed. For example, when using a clay mineral, for example, by adding a magnesium-based flocculant containing magnesium oxide, magnesium hydroxide, or the like as a main component, the powder particles are aggregated to increase the sedimentation speed of the powder in oil. In addition, the separation efficiency between the purified oil and the powder can be increased. Further, for example, if an appropriate amount of a calcium-based additive containing calcium hydroxide or the like as a main component is added, soil substances such as proteins dissolved in the oil are removed by the adsorbing action of the additive, etc. Off-taste, coloring, and the like can be suppressed.

It is also possible to use an inorganic substance powder containing an alkali component. When such an inorganic substance powder is used, the alkali component moves into the oil when it is brought into contact with and stirred with the oil, so that the oil itself is oxidized, or an acidic substance mixed in from the food is removed. The adverse effects such as off-flavors and off-flavors are alleviated. Further, since the oxidized oil component is reduced by the alkali component, the oil can be regenerated to a fresher state. In addition, because the oil itself is kept alkaline,
Oxidation of the oil after treatment does not easily progress.

The alkaline component used is a component that can be ingested by the human body and at least partially migrates into the oil to make it alkaline (ie, to increase the pH above 7). Then, it is desirable that the ingredient is hardly adversely affected such as reducing the flavor when transferred to food. Specifically, alkali components extracted from beans and grains such as soybeans are preferably used.

The oil storage container of the present invention has the same configuration as the above-mentioned oil filter of the present invention except that the filter receiving portion is not included in the essential components. Then, when the oil is poured out from the container main body, the same operation and effect as those described for the oil filtering device can be achieved.

In FIG. 4, the bottom surface of the recovery passage 9 has an inclined surface that is higher on the tip side of the first and second protrusions 6 a and 6 b in the circumferential direction of the opening 2 a and lower on the oil guide 10 side. 7a. As shown in FIGS. 1 and 5, handles 11 are integrally formed on both sides of the oil discharging section 6 on the side surface of the container body 2.

Next, as shown in FIGS. 1 and 4, the filter receiving portion 3 has a bottomed container-shaped filter receiving main body 3a having an opening 3c on the upper surface side and a peripheral portion of the opening of the filter receiving main body 3a. It has a flange portion 3b integrated therewith so as to protrude outward along it, and is entirely formed as a ceramic. Then, the filter receiving body 3a is accommodated in the inside of the opening 2a of the container main body 2 from the inside thereof, and is supported from below by the flange 3b by the flange 7 on the container main body 2 side.

The filter receiving main body 3a has an inverted truncated conical outer shape whose diameter is reduced on the bottom side, and a plurality of through holes 3d and 3e forming a liquid passage portion are formed at the bottom. In this embodiment, as shown in FIG. 6, a slightly large through hole 3d is formed near the center of the bottom of the filter receiving main body 3a, and a plurality of small through holes 3e are formed so as to surround the periphery. As shown in FIGS. 1, 4, and 6, a groove 3g is formed in the outer peripheral portion of the inner bottom surface of the filter receiving main body 3a along the circumferential direction. Further, in the side wall portion of the filter receiving main body 3a, a long hole-shaped through hole 3f extending in the height direction is provided at a predetermined interval along the circumferential direction of the filter receiving main body 3a such that the lower end side is in the groove 3g. Are formed.

As shown in FIGS. 1 and 4, a concave portion 3i is formed in the side wall portion of the filter receiving main body 3a, and a flange 3b is formed at a position corresponding to the concave portion in the radial direction of the filter receiving main body 3a. A wide portion 3h is formed so as to penetrate into it. And the positioning convex part 3j is formed in the form which protrudes downward in the wide part 3h. On the other hand, the flange portion 7 of the container main body 2 is formed with a wide portion 7b which is wide in the radial direction on the side opposite to the oil discharging portion 6 in the radial direction of the container main body 2, and has a thick portion. A mounting hole 7c penetrating in the vertical direction is formed. Then, the filter receiving portion 3 is mounted on the flange portion 7 of the container main body 2 with the positioning projection 3j inserted into the mounting hole 7c. The positioning convex portion 3j and the mounting hole 7c thereof may be interchanged in the positional relationship between the filter receiving portion 3 and the container body 2.

Next, as shown in FIG. 4, the lid 4 is entirely composed of a ceramic like the container body 2 and the filter receiving portion 3, and protrudes downward from the lower surface thereof along the outer edge circumferential direction. A ridge 4a is formed in the form. As shown in FIG. 7, in a state where the opening 2 a of the container body 2 is closed by the lid 4, the ridge 4 a is
a recovery passage 9 formed between the first protrusion 6a and the second overhang 6b.
(Opening 2a) of the container body 2

Next, a lid-side projection 4b is formed at the center of the lower surface of the cover 4 so as to protrude from the lower surface. Are formed. Then, as shown in FIG. 8, the lid 4 is removed from the container body 2 and turned upside down, for example, is placed on a predetermined placing surface F, and the receiving-side concave portion 3k is placed on the top of the lid-side convex portion 4b. The filter receiver 3 can be held on the lid 4 in the fitted state. Here, as shown in FIG. 7, a concave portion 4c is formed on the upper surface side of the lid at a position corresponding to the lid-side convex portion 4b, and the lid 4 is placed on the bottom surface of the concave portion 4c. A knob portion 4d for attaching and detaching to and from the projection is formed to protrude. on the other hand,
The groove 3g on the filter receiving portion 3 side is, as it were, a by-product along the outer edge of the convex portion formed on the bottom inner surface side with the formation of the receiving portion side concave portion 3k. Will be actively used as a guide groove for guiding.

The method of using the oil filter 1 and its operation will be described below. First, as shown in FIG. 9, the filter receiver 3 is set on the container body 2, and the filter 5 is set on the filter receiver 3. Next, the inorganic substance powder P is put into the filter 5, and high-temperature oil M 'such as dirty tempura oil is poured into the filter. The inorganic substance powder P comes into contact with the oil M 'and evaporates moisture by its heat. The oil bubbles M ′ in the filter 5 due to the bubbles of water vapor accompanying the evaporation
Is vigorously stirred, and the dirt component in the oil M ′ is captured and removed by the powder particles. Note that the filter 5
Is formed in an inverted truncated cone shape corresponding to the inner surface shape of the filter receiving portion 3, and a relatively large space is secured inside thereof, so that the oil M ′ and the inorganic substance powder P Stirring proceeds well. In addition, it is of course possible to use the inorganic substance powder P without using it.

Then, while the scum and burnt matter in the oil M ′ and the solid matter such as the inorganic substance powder P are filtered off by the filter 5, the purified oil M that has passed through the filter 5 is The liquid is collected in the container body 2 through the liquid passage portion of the filter receiving portion 3, that is, through holes 3d to 3f. That is, the oil M that has passed through the bottom of the filter 5 falls directly from the through holes 3d and 3e formed in the bottom of the filter receiving portion 3, while the oil M that overflows to the side is collected in the groove 3g,
It is efficiently discharged from the lower part of the long through hole 3f. Further, for example, even if the vicinity of the bottom of the filter 5 is clogged with the inorganic substance powder P, the oil M can permeate through the side wall of the filter 5 and flow directly out of the through hole 3f. M can efficiently permeate the filter 5 in a form in which the entire filter 5 is used uniformly, and thus can quickly recover the filtered oil M. Further, since the container body 2 is made of a ceramic, the temperature is hardly increased when high-temperature oil is collected, and the handling is easy.

When the oil M has been collected, the lid 4 is attached to the container body 2 and stored as shown in FIG. 2 or FIG. When the oil M in the container main body 2 is to be reused, the lid 4 and the filter receiving portion 3 are removed, and FIG.
In the state shown in (a), the container body 2 is tilted as shown in FIG.
As shown in FIG. 7, a gap J is formed between the flange portion 3b of the filter receiving portion 3 and the second overhang portion 6b of the oil pouring portion 6, into which a finger is inserted to insert the flange portion. When hooked on 3b, the filter receiver 3 can be easily removed by raising it.

When the container body 2 is tilted as shown in FIG. 10 (b), the oil M flows out in a narrowed form at the projecting tip of the second projecting portion 6b. Then, when the supply of the oil M is completed, the inclination of the container body 2 is returned to the original. Here, the second overhang portion 6b
Is higher than the first overhanging portion 6a, so that the overhanging end of the first overhanging portion 6a has a height corresponding to the difference in height from the drop trajectory of the oil M. The oil M is drawn into the container body 2 side, so that the outflowing oil M is hard to contact. As a result, when the inclination of the container main body 2 is returned, oil dripping is less likely to occur at the overhanging tip portion of the first overhang portion 6a. On the other hand, the second overhang portion 6b
In FIG. 10 (c), oil dripping occurs on the outer surface as shown in FIG.
The water flows through the recovery passage 9 down the inclined surface 7a in FIG. 4, and is further recovered in the container main body 2 through the oil guide 10 as shown in FIG.

As shown in FIG. 11, the container body 2 may be made of metal such as stainless steel. In this case, for example, the first overhang 6a can be formed integrally with the wall of the container body 2 by sheet metal pressing or the like, and the second overhang 6b can be formed by welding or screwing to the container body 2. . In this case, a bottomed groove-shaped recovery passage is not formed between the first overhang portion 6a and the second overhang portion 6b, and the lower side of the container body 2 is formed as shown in FIG. A gap L open to the inside may be formed.
