When purifying the degraded oil after cooking, the degraded oil is put into the filtration unit 1 on which the filter paper 7 and the net 6 are placed. The net 6 removes the cooking debris in the degraded oil and at the same time prevents the filter paper 7 from shifting. The filter paper 7 removes fine cooking residues that could not be removed by the net 6. The degraded oil falls into the oil storage unit 2 through the filter 3 fitted in the hole 8 at the bottom of the filter housing 1a. When the sheet of the cover 10a of the filter 3 is the filter paper 7, the fine cooking residue that could not be completely removed is further removed.

When a deteriorated oil having an acid value of 0.50 is filtered with a filter having a diameter of 8 cm and a depth of 3 cm, the acid value is 0.39 with a filter filled with only 24 g of activated carbon. The condition improved, but 18.0 g of calcium hydroxide and activated carbon 1
The filtration filter filled with 6.0 g had an acid value of 0.37, the acid value of 0.13 was reduced, the state of the oil was improved, and the acid value could be further improved.

The acid value of the filtration filter filled with 6.0 g is 0.37.
0.13 can be improved, and the yellowness is 62. However, 15.0 g of calcium hydroxide and 14.0 g of activated carbon,
The acid value of the filtration filter filled with 15.0 g of activated clay was 0.36, which could be improved by 0.14, and the yellowness was 60, and both the acid value and the yellowness of the deteriorated oil could be improved.

FIG. 5 is a vertical cross-sectional view of an oil purifier in which calcium hydroxide, activated clay and activated carbon are filled in order from the top into the filter 3. When the deteriorated oil passes through the filter 3, the acid in the deteriorated oil is first neutralized by calcium hydroxide, and the coloring component is adsorbed and removed when passing through the activated clay. However, when the deteriorated oil passes through the activated clay, oxides may be generated.Therefore, by passing the deteriorated oil through activated carbon last, the generated oxides and odors are adsorbed and removed by the activated carbon, and the purified oil is removed. It can be further purified without returning.
