Description of the Related Art Conventionally, edible oils used not only at home but also at food factories and restaurants are discarded at a certain period while being used while removing fried scum and removing oil. At present, it has hardly been purified. The primary reason is that there has been no simple method of deoxidizing degraded edible oil. For example, the deoxidation method of refining new oil, which is well known as a method of removing fatty acids that are the main cause of oil deterioration, includes (1) direct alkali addition to crude oil, such as a caustic soda method, a soda ash method, and an ammonia method. (2) a method of dissolving crude oil in a solvent, such as a micelle purification method, a furfural extraction method, and a propane extraction method, and (3) a fatty acid distillation method and (4)
Esterification methods and the like are known. However, any of these conventional deoxidation methods requires large equipment and the like. For example, as equipment, a tank for receiving degraded oil, a tank for containing and stirring an adsorbent, and an apparatus for separating the adsorbent (Centrifuges, press filters, etc.), tanks for storing deoxidized oil, etc. are required, which not only requires investment and space, but also requires operations by specialized technicians and experienced persons, food factories and It could not be easily introduced in restaurants.

は環境問題上極めて深刻な問題となっている。In addition, it is actually troublesome to arrange the above-described equipment in a kitchen where frying is performed and to perform deoxidation. Generally, only the frying operation is busy, but as an additional operation, edible food used for frying is added. Deoiling the oil is a heavy burden on the operation. Therefore, as a practical condition, the filter is merely installed to remove coarse fried scum, and is disposed after a certain period of time. Today, half of 2 tons of edible waste oil is said to be 40 tons per year.
As much as 100,000 tons have been illegally dumped, and edible waste oil has become an extremely serious environmental problem.

る。Next, the method for regenerating the edible oil of the present invention will be specifically described. In the regeneration method of the present invention, first, the deoxidizing agent of the edible oil of the present invention is mixed with the degraded edible oil, and the deoxidizing agent is stirred to remove impurities such as impurities, water, and fatty acids in the degraded oil. Adsorb. In the case of processing large volumes of degraded oil,
The deteriorated oil is charged into the receiving tank, and then the deoxidizing agent of the present invention is charged therein. Thereafter, the temperature of the deteriorated oil is preferably 60 to 180 ° C, more preferably 80 to 120 ° C. It is desirable to perform stirring while heating. On the other hand, in the case of a small-capacity treatment, it is preferable that the high-temperature degraded oil immediately after use is directly charged into a receiving tank and stirred beforehand or with the deoxidizing agent of the present invention which is charged immediately after. As described above, the adsorption speed can be increased by performing the adsorption with the temperature of the degraded oil raised, but it is needless to say that the adsorption can be performed at room temperature.

的にも極めて優れているといえる。The acid value of the degraded oil used in the regeneration method of the present invention is preferably 3.0 or less. The reason for this is that if the deterioration has progressed so much, the number of times of repeated use cannot be sufficiently increased, and eventually, it must be discarded. It is particularly preferably 1.5 or less, and 20 to 30% of new oil is added to the edible oil after the separation treatment. As a result, it is possible to obtain a delicious food which is always satisfactory in all of "taste", "color", "scent", "kosi", etc., does not generate waste oil, and furthermore, the adsorbed deoxidizer separated by the separation treatment. Can be suitably used as an organic fertilizer, so that it can be said that it is extremely environmentally friendly.

After about 10 minutes of the adsorption time, separation treatment was performed with the filter press 3, and the regenerated oil was stored in the new oil tank 4. In addition, 2 in the figure

The acid value reduction rate was slightly reduced to 0 to 50% with a decrease in the adsorption area, but the result was much higher than the total work efficiency.

00: 3000 (cc), which is about a 15-fold difference. This is because in Comparative Example 2, the sedimentation state was loose, and when the supernatant was sucked, the separated deoxidizer was mixed into about 3000 cc of the supernatant oil and remained, whereas in Example 2, the sedimentation state was hard and the supernatant was removed. This is because even if about 200 cc remains after suction, the precipitate can be flowed out as it is at the last inclination. In Example 2, the oxidation reduction rate was 20
-30%, while in Comparative Example 2, 30-50%
However, the acid value reduction rate slightly decreased with the decrease in the adsorption area, but the result was much higher than the yield.

約２０分もあれば十分である。The reason why the adsorption time is set to be as long as 6 hours is that the usability at the actual kitchen site is considered. That is, for quick cleanup, it is better to immediately treat the hot oil that has just dropped the fire, while it takes about 6 hours to pump up the fryer at the beginning of the next day. In fact, about 20 minutes is enough for the adsorption effect to settle.

(−180 ° C.), and left for 20 minutes to perform natural filtration. Specific processing conditions are as follows.
【００３３】（実施例３） 濾過助剤：不要 使用量：活性白土（粒径１００μｍ）３００ｇ 作業時間：２０リットルの劣化油に対し濾過時間２０分(Example 3) Filtration aid: unnecessary Usage amount: activated clay (particle size: 100 μm) 300 g Working time: 20 minutes for 20 liters of deteriorated oil
【００３４】 （比較例３） 濾過助剤：（珪藻土）２０％〜５０％を混合させて使用 使用量：活性白土（粒径６μｍ）３００ｇ 珪藻土 １００ｇ 作業時間：２０リットルの劣化油に対し濾過時間６時間(Comparative Example 3) Filtering aid: (Diatomaceous earth) used by mixing 20% to 50% Amount used: Activated clay (particle size: 6 μm) 300 g Diatomaceous earth 100 g Working time: Filtration time for 20 liters of degraded oil 6 hours
【００３５】平均粒径６μｍを止めるメッシュの濾紙を
使用した結果、比較例３では油膜状態になり自然落下で
は濾過ができなかった。即ち、脱酸剤が濾紙に対し油膜
を張ってしまい、油が殆ど濾紙を通過しなかった。濾過
助剤と脱酸剤の配合比率を逆転させれば濾過可能となる
が、酸価値削減率が大幅に低下する結果となる。As a result of using a filter paper having a mesh that stops the average particle diameter of 6 μm, in Comparative Example 3, an oil film was formed and filtration was not possible by natural fall. That is, the deoxidizing agent formed an oil film on the filter paper, and almost no oil passed through the filter paper. If the mixing ratio of the filter aid and the deoxidizer is reversed, filtration becomes possible, but the acid value reduction rate is greatly reduced.
【００３６】実施例３では酸化削減率が２０〜３０％で
あるのに対し、比較例１では３０〜４０％と、吸着面積
の減少にともない酸価値削減率は若干低下したが、作業
効率をトータルでみるとそれをはるかに上回った結果が
得られた。In Example 3, the oxidation reduction rate was 20 to 30%, while in Comparative Example 1, the acid value reduction rate was slightly reduced to 30 to 40% as the adsorption area was reduced. In total, the result was much higher.

ができることから、環境的にも極めて優れている。As described above, according to the present invention, the separation capacity in the subsequent separation treatment is greatly improved without significantly lowering the adsorption capacity, and the edible oil can be safely, simply and efficiently degraded. Can be reproduced, and the number of times of repeated use can be greatly extended. In addition, regenerated oil always gives satisfaction to all of “taste”, “color”, “fragrance”, “koshi”, etc., greatly reduces waste oil, and uses adsorbed deoxidizer separated by separation process. Since it can be used as an organic fertilizer, it is extremely environmentally friendly.
