Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a device for regenerating oil, particularly edible oil.

(Prior Art) The conventional idea disclosed as a measure to prevent deterioration of oil is to filter food debris with a filter material such as activated carbon or activated clay or a filter, deoxidation such as caustic soda and alkaline earth metal oxides. A method of deoxidizing using an agent, or a method of preventing oxidation by applying a voltage to generate negative ions.

(Problems to be solved by the invention) However, the filtration efficiency of the above-mentioned filtration materials such as activated carbon is not durable, the filtration materials cannot be regenerated, and the adsorption action is sufficient to sufficiently remove food juice. However, there is a problem in that it is not possible to sufficiently prevent oxidation due to decomposition of oil molecules.

Further, although the use of a deoxidizing agent or negative ionization has some effect on preventing oxidation, there is a problem in that deterioration over time cannot be prevented because filtration or purification is not performed. The deoxidizing agent has a relatively short life, and it is troublesome to perform supplementary work. Negative ionization has a problem that the power consumption of the apparatus increases and a complete countermeasure facility is required.

While the present inventor has taken the above problems into consideration, the deterioration of edible oil is such that food debris, food juice, etc. accumulate in the oil tank and decompose with use, and further, these food debris and food juice are convected by heating. Burning to fried foods, oil molecules decomposed over time due to repeated heating, free fatty acids are also generated together with fats in fried foods, oil-soluble gum substances are decomposed and released, and food juices and the like bind to oil. It is thought that the main cause is to emulsify, etc., and it is thought that these are caused by comprehensively affecting, and based on this thought,
The purpose of the present invention is to enable filtration and purification and oxidation prevention at the same time, and to enable regeneration with a simple device.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention provides an oil filtration section in which an oil filtration section is detachably mounted, and the oil filtration section is provided with a filtration tank capable of supplying an appropriate amount of oil. A first filtering portion having a mesh surface disposed inside the oil inlet of the filtration tank or inside the tank, and a second filtering portion having a filter paper surface disposed on the oil outflow side of the filtration tank; An active material for filtering the oil that has passed through the second filter, that is, an animal bone, is boiled and then 900-110.
Bone bone powder obtained by firing and crushing at around 0 ° C. and binder soil powder obtained by firing and crushing inorganic clay having an adsorbing action are kneaded, granulated, and further fired as appropriate. An active material formed to have a size, and a third filtration portion detachably attached to the filtration tank, the oil passing through the oil filtration portion being stored in the storage tank. The oil regenerating apparatus is configured as described above.

(Operation) After filtering particles such as fried dregs in the first filtering section, filtering finer particles in the second filtering section, filtering a part of food juice, and preventing oxidation in the third filtering section, Deodorize and decolorize and perform ion exchange. Moreover, the first and second filtering sections effectively improve the function of the third filtering section. The oil regenerated by filtration is stored in an oil storage tank and is reused as appropriate.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 and 2, in the device of the present invention, a filtration tank 2 is detachably fitted in an upper part of an oil storage tank 1, and a first filtration part 3 is attached to an upper surface of the filtration tank 2. Is detachably fitted, the second filtration portion 4 is arranged on the lower surface of the filtration tank 2, and the upper end portion of the third filtration portion 5 is detachably fitted on the lower end outlet portion of the filtration tank 2. ing. 6 is a lid.

The oil storage tank 1 is a rectangular parallelepiped container in the figure,
It can be formed in an arbitrary shape including other components, and a spout 11 is formed at one end of the upper surface of the container so as to slightly project laterally, and a large opening 12 is formed at the other end of the upper surface.
Is formed, the periphery of which serves as an engaging collar 13, the inside serves as an oil storage space 14, and the handle 15 is formed outside the body.

As shown in FIG. 3, the filtration tank 2 has a size that is arranged in the upper part of the oil storage tank 1 and has an internal space 21.
The upper surface has an opening 22, the outer peripheral edge of which serves as a locking edge 23 that can engage with the engaging flange 13 of the opening peripheral edge of the oil storage tank 1, and a horizontal edge 25 having a slightly wider peripheral edge with a step at the center of the lower surface. The opening 24 is formed.

As shown in FIG. 4, the first filtering part 3 is arranged at the opening 22 of the filtering tank 2, and the receiving bottom surface is made of aluminum, stainless steel or other metal, for example, 0.3 to 1 mm.
A mesh surface with front and rear holes (a punching material etc. may be used)
31, the upper peripheral edge is a locking edge 32 that locks with the peripheral edge of the opening 22 of the filtration tank 2, and a hook 33 bent downward is formed on the upper edge on one side.

As shown in FIG. 1, the second filtration section 4 is a liquid-permeable filtration surface as a filter paper such as a non-woven fabric capable of filtering fine particles, and is a sheet that is in close contact with the lower surface of the filtration tank 2 and closes the opening 24. It is formed and arranged as a sheet. The sheet-like body may have a single-layer structure or a multi-layer structure, and can be appropriately removed. In addition, it is more preferable in terms of filtering function to use the filter paper formed by previously containing burned bone powder, that is, active material powder, which will be described later. The oil receives the action of the active material when passing through the second filtration section 4,
The third filtering unit 5 described later is not limited to merely filtering fine particles.
It also performs the filtering and regenerating action in (3) and assists the function of the third filtering unit 5.

As shown in FIG. 5, the third filtering portion 5 has a locking collar 52 that engages with a horizontal edge 25 of the peripheral edge of the opening 24 of the filtration tank 2 on the outside of the upper peripheral edge of the cylindrical body 51 whose upper and lower surfaces are open. The upper and lower openings are closed by the fine mesh surfaces 53 and 54 similar to the above, and the active material 55 is filled almost completely inside. If the mesh surface 53 on the upper surface is detachably attached, the active material 55 inside can be washed appropriately, which is desirable.

The third filtration part 5 is engaged with the lower surface of the filtration tank 2, the second filtration part 4 is disposed on the third filtration part 5, and the first filtration part 3 is fitted to the upper surface of the filtration tank 2 to fit the oil filtration part. The oil regenerating apparatus of the present invention is constructed by arranging the oil filtering section inside the oil storage tank 1 from above.

The active material 55 is formed as follows.

While cutting the growth of animals mainly composed of bones such as cows, horses and sheep to an appropriate size, they are cut to a size that is easy to burn,
Then, put it in a pressure cooker (compression cooker), for example 200-400 ℃
Boil for about 90 minutes before and after to separate and remove most of the organic substances attached to not only the outside of the bone but also the myriad pores from the bone. Next, this bone is put into a firing furnace, fired at about 900 to 1100 ° C. for about 60 to 180 minutes, placed in the furnace as it is, and naturally cooled for about 60 minutes, for example, and returned to room temperature or a state close thereto. Firing without a boiling step is not preferable because it causes significant combustion of organic substances and generation of smoke. If the firing conditions are clearly lower than the above, the bone will carbonize, and if it is too high the bone will turn to ash. According to the above conditions, the bone is whitened and maintains the original tissue state having numerous pores. Cooling after firing is preferably performed in a dry state. In this way, it is possible to obtain a baked bone having a water content of 1% or less and free of organic substances.

After firing and cooling, crush this bone and apply a powder machine.
About 20 to 200 mesh, and particularly preferably 50 to 100 mesh powdery bone meal.

The bone powder has a large number of fine pores in a communicating state, and when mixed with city water, the city water becomes an alkaline ion state of about pH 11 for granular bone and about pH 8 to 10 for powdery bone.

On the other hand, for example, zeolite, carion, or other inorganic clay having an adsorbing action is calcined at about 600 ° C. for about 3 hours, then pulverized into a clay powder of about 200 to 500 mesh, and prepared in advance as a connecting earth powder to be kneaded with the bone powder. And above the bone powder 40
~ 90% by weight and a mixture of the above clay powder 10 ~ 60%,
Add about 20-30% water, knead, granulate, and sinter at about 800-1000 ° C to form a sphere with a diameter of 1-20 mm, or a thickness of 5
The active material is finished into a rod shape of about 10 mm or an arbitrary size shape of the same degree.

The active material 55 housed in the third filtration unit 5 has a mixing ratio of the above bone powder of about 40 to 70% to the extent that the oil regenerating effect can be exhibited, and calcination is performed at about 800 to 900 ° C in accordance with the change of the mixing ratio. However, in order to increase the contact area of the filter medium in the filtration section, it is more preferable that the size is about 1 to 5 mm.

In the above, when the active material is used for edible oil, the binder soil powder needs to be one that can be used as a food additive. Further, it is preferable that the binder soil powder has, for example, a mixture of zeolite and a metal oxide such as alumina as a binder to enhance conductivity.
Furthermore, wood flour, chaff powder, together with bone meal and binder soil meal,
By mixing and burning malt flour or other combustible inorganic powder such as around 50 to 150 mesh, the inorganic powder is extinguished and more bubbles of the active material are formed, resulting in contact. The surface area is further increased, which is preferable.

It should be noted that the specific examples of the above-mentioned active material do not limit the scope of the present invention.

The active material formed as described above ion-exchanges the liquid from the acidic side to the neutral or alkaline side by the action of calcium ions or the like. At the same time, it acts to prevent the decay of organic substances, or acts to prevent the oxidation of organic substances due to adsorption or aggregation, thereby maintaining the freshness. Filtration and purification can be performed by the adsorption action due to the existence of innumerable bubbles. These effects are theoretically long-lasting in the presence of bone.

In addition to the above ionization, the adsorptive capacity of aggregates neutralizes and adsorbs free fatty acids that are one of the causes of oil deterioration, and adsorbs oil-soluble gum substances that are desorbed by thermal decomposition to prevent oil oxidation. Planned.

Furthermore, the aggregate has the effect of deodorizing and decoloring the offensive odor and turbidity associated with the oxidation of oil, and maintaining the state of fresh oil due to its active adsorption capacity.

The active material 55 in the third filtration unit 5 can be reused by appropriately taking out, washing and removing the deposits, and the above-mentioned action of the aggregate can be continued.

According to the above-mentioned device of the present invention, when used oil is poured onto the first filtration unit 3, the oil passes through the first filtration unit 3 and the filtration tank in a state in which filtered substances such as food residue are removed. 2 and then passes through the second filtration section 4 to be further sufficiently filtered and then filtered by the third filtration section 5 as described above,
The activity is performed, most of the impurities in the oil are filtered, the organic matter and the oil-soluble gum substance are adsorbed and removed, and the boiled material in which the food juice and the oil are emulsified is adsorbed, and the free fatty acid is neutralized and adsorbed, The oil is alkalized by ion exchange, is given a mineral content, and is deodorized and decolorized to be like new oil and stored in the oil storage tank 1. This oil can be reused accordingly.

The above embodiment is an example of an apparatus, and it is also possible to arbitrarily change the design of a specific configuration other than the above, for example, to incorporate the third filtration unit 5 in the lower portion of the filtration tank 2. Of course, it can be added.

(Effects of the Invention) In this way, according to the present invention, a simple device is used to adsorb and remove food debris, food juice, etc. that accumulate with daily use from oil, and at the same time, release fatty acids and oil-soluble gums. It is possible to adsorb and remove quality, adsorb and remove emulsions that are formed by the combination of food juice with oil, and deodorize and decolorize the oil used. At the same time, the oil is alkali-ionized and activated by calcium content. Minerals can be leached and replenished, and used oil can be regenerated almost like new unused oil.

In the case of edible oil, the finished state of deep-fried food can be always maintained, and by supplementing minerals, the effect of preventing obesity due to cholesterol is also exerted.

In addition, the active material used in the filtration part can be reused as a filtration material because the adsorbed component can be removed by sufficient washing and the active effect of the aggregate is maintained, and the entire device can be easily used. In addition, it can be configured as a compact one and can be efficient.
