Description

[Technical field]

[0001] The present invention relates to an oil purifier that purifies edible oil for use in order to prevent problems such as problems caused by fried food residue clogging the edible oil and shortening the lifespan of the oil when cooking fried foods using edible oil. More particularly, the present invention relates to an oil purifier that prevents fine fried food residue contained in edible oil from flowing back into a deep fryer without passing through a filter after flowing in, thereby purifying edible oil more completely. [Background technology]

[0002] Recently, with the development of Western-style food culture featuring fried foods such as fried chicken and fast food, the use of edible oil has increased sharply. In general, in deep-frying machines at restaurants, new edible oil is poured into the frying drum and used repeatedly many times. However, the more the oil is used, the more it deteriorates due to oxidation when exposed to air and carbonization due to fried debris. A considerable amount of used edible oil is discarded after the appropriate number of uses, which is causing serious problems such as environmental pollution and resource waste.

[0003] In light of these problems, oil refiners capable of refining and recycling frying oil have become widespread and are being used. However, conventional refiners use a gravity-flow filtration method for refining, and the quality of the refined edible oil is limited to removing foreign matter, which is not up to expectations, so their use is avoided.

[0004] Meanwhile, in order to solve the above problems, an oil refiner has been developed and is being used that is equipped with a separate filter to refine edible oil more completely, and first refines the oil through a filter net, and then removes fine foreign matter through the filter.

[0005] However, although the use of the above-mentioned oil refiner is more effective than the method of refining oil through a filter net, a considerable amount of sludge is discharged after seeping into the filter without passing through the filter. As a result, it is true that there is a limit to completely removing foreign matter such as sludge contained in the oil. [Prior art documents] [Patent documents]

Hereinafter, a preferred embodiment of the present invention will be described with reference to the attached drawings.

[0014] Hereinafter, a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

[0015] FIG. 1 is a perspective view of the present invention in an entirely assembled state, FIG. 2 is an exploded perspective view of the present invention in an entirely disassembled state, FIG. 3 is an enlarged perspective view of a support member in the present invention, FIG. 4 is an enlarged perspective view of a packing in the present invention, and FIG. 5 is a cross-sectional view of the present invention in an assembled state and an enlarged cross-sectional view of a main part.

[0016] As shown in the attached drawings, in order to solve the problem of fried flour and the like clogging up cooking oil during deep frying using cooking oil in a deep fryer (not shown), the present invention is characterized by the structure of an oil purifier that is installed under a deep fryer to drain the oil in the deep fryer and then purify it primarily with a filter net (not shown) to more completely purify fine foreign matter.

[0017] As shown in FIG. 1, the oil refiner stores oil inside the main body 100, refines the oil through a filter 130, and discharges the refined oil to the bottom of the main body 100 before flowing back into the deep fryer.

[0018] Here, as shown in the attached FIG. 2, the main body 100 is provided with casters 101 on the bottom surface for easy movement, and is provided with a storage unit 102 for storing oil discharged from the deep fryer on the inside. A discharge hole 103 for discharging the oil is formed on the lower side of the storage unit 102, and the bottom surface is inclined toward the discharge hole 103 so that the oil can be naturally discharged. Also, a circulation pump 104 is provided on the inside for pumping the oil flowing in through the discharge hole 103 to an upper circulation pipe 105 and supplying it to the deep fryer. A residual oil discharge pipe 106 is provided on one side for manually discharging the residual oil, and when performing work such as cleaning the storage unit 102, the residual oil can be manually discharged by opening the residual oil discharge pipe 106.

[0019] Meanwhile, after cooking oil is flowed into the storage section 102 of the main body 100, only the oil refined through the filter 130 is discharged through the discharge hole 103. In this case, the filter 130 is generally a refinement filter made of carbon, and in the present invention, various filters 130 can be used to maximize the performance of the filter 130.

[0020] For example, the filter 130 may be made of a powder containing a combination of silicon dioxide and magnesium oxide.

[0021] In addition, the filter 130 may be made by mixing one or more selected from illite, sericite, germanium, guiangite, peat, and activated carbon, crushing the porous mixture to a particle size of 5 to 30 μm, mixing the porous mixture with a binder solution in a weight ratio of 1:0.5 to 3, and heating the porous mixture mixed with the binder solution at a temperature of 300 to 500° C. for 3 to 7 hours to heat-treat the porous carrier. The porous mixture may be heat-treated by adding 2 to 3 parts by weight of microorganisms to 100 parts by weight of a microorganism-infused porous carrier, and adding 5 to 15 parts by weight of a growth promoter-adsorbed porous carrier to which 2 to 5 parts by weight of natural vegetable oil is added to 100 parts by weight of the growth promoter-adsorbed porous carrier.

[0022] Alternatively, the filter 130 may be prepared by dissolving 30 g of Li-MoO3 in 100 g of pure distilled water having a temperature of 90° C., adding 5 g of platinum chloride, 10 g of nickel chloride, 10 g of calcined adsorbent, 10 g of iron sulfide, 5 g of vanadium pentoxide, 5 g of bismuth, 5 g of tungsten oxide, 5 g of titanium dioxide, 2 g of carbon, and 3 g of silver oxide in that order, stirring for 2 hours, and then cooling to room temperature.

[0023] By using various filters 130 as described above appropriately according to the requirements of the working environment, the life of the filter 130 can be increased and the oil purification function can be maximized.

[0024] Meanwhile, when providing the filter 130 as described above on the bottom surface of the storage section 102, if the filter 130 is not provided at a certain height from the bottom surface, the oil will not pass through the filter 130 and then be discharged through the drain hole 103. Therefore, in order to provide the filter 130 above the bottom surface as described above, a support member 120 is provided on the bottom surface of the storage section 102.

[0025] As shown in the attached Figs. 2 and 3, the support member 120 comprises a pressing surface 121 installed on the upper surface of the packing 110, a right angle surface 122 bent from the inside of the pressing surface 121 to the lower end, and a support surface 123 bent from the right angle surface 122 to the inside. The support surface 123 is perforated with a number of through holes 124 through which oil passes, and handles 125 are provided on both sides of the upper end of the pressing surface 121.

[0026] The support member 120 constructed as described above is inserted into the bottom surface of the storage section 102, and the filter 130 is placed on the support surface 123 to perform the oil refining operation. When the performance of the filter 130 deteriorates after prolonged use, the filter 130 can be replaced by lifting the handle 125.

[0027] In addition, a number of through holes 124 perforated in the support surface 123 serve as passages for discharging the oil refined through the filter 130. In the present invention, as shown in the attached drawings, the size of the through holes 124 is uniform overall, but the through holes 124 formed above the portion where the discharge hole 103 is located are relatively small.

[0028] This is because when oil is discharged through the through holes 124, the flow of oil in the area where the drain hole 103 is located is faster than the flow of oil in other areas as the oil is discharged to the drain hole 103. In response to this, the through holes 124 in the area where the flow rate is faster are formed smaller and finer to support the filter 130 more stably and prevent the filter 130 from dripping toward the drain hole 103.

[0029] Meanwhile, in order to prevent problems caused by the filter 130 floating or moving left and right when the filter 130 is placed on the support member 120 and used, a pressing member 140 is provided.

[0030] As shown in the attached FIG. 2, the pushing member 140 is characterized by comprising a pushing frame 141 for pushing and supporting the frame of the filter 130, and a pushing spring 142 provided on the upper side of the pushing frame 141 for applying pressure to the pushing frame 141 by tensioning action.

[0031] Here, with the filter 130 fixed in the above manner, the oil in the fryer is discharged into the storage section 102, and then the refined oil from which foreign matter has been removed as the oil passes through the filter 130 in a gravity-drop manner is discharged through the discharge hole 103, and then discharged by the circulation pump 104 into the circulation pipe 105 installed on the upper side and flows back into the fryer.

[0032] At this time, the foreign matter that passes through the filter 130 is refined by the filter 130, but the oil and foreign matter that do not pass through the filter 130 usually seep into the gap between the filter 130 and the wall of the storage part 102 and are discharged through the discharge hole 103 in an unrefined state and then flow back into the fryer. Therefore, there is a problem that the foreign matter cannot be completely removed even if the oil is refined.

[0033] Therefore, in order to extend the life of oil and improve the taste and quality of fried foods through perfect refining, which is the core of the present invention, it is important that the oil and foreign matter flowing into the storage unit 102 are discharged only through the filter 130, and in order to solve this problem, the packing 110 is provided.

[0034] As shown in the attached Figs. 2 to 4, the packing 110 is in the form of a square frame installed on the lower inner peripheral surface of the storage part 102, and is characterized by having grooves 111 formed on the upper and lower surfaces.

[0035] When the packing 110 is placed on the lower inner peripheral surface of the storage section 102 and the support member 120 is placed on the upper surface of the packing 110, the pressing surface 121 of the support member 120 presses the upper surface of the packing 110, so that the outer peripheral surface of the packing 110 is in close contact with the inner peripheral surface of the storage section 102.

[0036] When the packing 110 is in close contact with the inner circumferential surface of the storage portion 102 as described above, in order for oil to flow into the storage portion 102 and then escape to the discharge hole 103, the oil must be refined through the filter 130 before it can escape to the discharge hole 103.

[0037] This allows the fine impurities contained in the oil to be more completely refined, resulting in the reduction of the oil's rancidity and the maximal extension of its lifespan, thereby improving the taste and quality of fried foods.

[0038] Meanwhile, FIG. 6, which shows another embodiment of the packing 110, shows a packing 110 with a metal ring rod 112 inserted inside. This is to compensate for the drawback that the rubber packing 110, which is in the shape of a square frame, is difficult to maintain a constant shape when it is installed inside the storage unit 102 due to the characteristics of the rubber material. The packing 110 as described above can be constructed by insert molding after inserting the ring rod 112.

[0039] Although the present invention has been described above using limited embodiments and drawings, it is of course not limited to the above embodiments, and various modifications and variations can be made from the above described contents by a person having ordinary technical knowledge in the field to which the present invention belongs.

[0040] Therefore, the technical idea of ​​the present invention should be understood by the claims set forth below, and it is clear that all equivalent or similar modifications fall within the scope of the technical idea of ​​the present invention. [Explanation of symbols]
