[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to embodiments of frying oil. The oil reduction mechanism of the present invention is composed of three members: a ceramic plate 1, a stock can 2, and a waste oil recycling machine 3.

First, the ceramic plate 1 is formed of a ceramic plate having an appropriate shape such as a circular shape or a square shape, and is a fryer pan 4 (hereinafter, in this specification, includes a commercial large-scale fryer such as a fryer). Any size may be used as long as it can be stably installed in the inside, but usually a disk having a diameter of about 10 to 20 cm is preferable.

As an example of the structure of the ceramic plate 1, alumina (10 to 10) is used in order to improve the radiation efficiency of far-infrared rays that perform heat transfer inside the fried material 5.
30% by weight), zirconia (10 to 30% by weight), titanium oxide (5 to 30% by weight), feldspar (20
-30% by weight).

The ceramic plate 1 is immersed in the fryer 4 before the oil in the fryer 4 is warmed. The far-infrared light emitted from the ceramic plate serves as a heating effect transmitted from the heated oil. Fried food material 5
Are synergistically heated. As a result, even when the temperature of the oil is slightly lower than the normal frying temperature of about 170 to 175 ° C. (in the conventional example not using the ceramic plate 1, the frying was performed at about 180 ° C.), the same delicious fried food as the conventional one was obtained. Will be obtained. Increasing the oil temperature promotes the oxidation of the oil (in general, it is said that if the oil temperature rises, the oxidation will proceed at the square ratio of the rise temperature). In the present invention, the oil frying temperature can be lowered, so that the oxidation of the oil can be delayed.

Then, after a certain period of time, the fryer 4
When the oil inside is deteriorated (oxidized) and it is time to replace it with new oil, frying scum is roughly removed with a strainer or the like, and then the oil 6 to be treated is first transferred to the stock can 2, and Is stored until the temperature of the oil to be treated 6 becomes 90 ° C. or less. Suddenly transferring the oil to be treated 6 to the waste oil recycling machine 3 causes the waste oil recycling machine 3 to break down.

An appropriate position, preferably a bottom position, of the stock can 2 is a Io stone 7 having a reducing effect and a plant humus (humic acid) 8 having a deodorizing and rot preventing effect, and a lid 9 made of a copper plate mesh. The oil 6 to be treated comes into contact with the Io stone 7 and the vegetable mulch 8, and the treated oil 6
Can exhibit a sufficient reducing action, antioxidant action and deodorizing action. Further, if necessary, it is effective to add lignite having a high deodorizing effect in the lid 9.

The oil 6 to be treated after a certain period of time in the stock can 2 is guided to the hopper 10 of the waste oil recycling machine 3 and is dropped downward from the hopper 10 to filter element 11 (cellulose fiber element of about 5 μ mesh). Etc. are preferable), and a filtration step is performed. This filtration step is repeated several times at a flow rate of about 2.5 to 3 liters / minute, depending on the state of deterioration of the oil 6 to be treated.

The oil to be treated 6 that has passed through this filtration step passes through a feed pipe 12a, and is passed through a tank chamber 13 of a waste oil recycling machine.
It is led to. A pair of electrodes 14 is provided at an appropriate place in the tank chamber.
a and 14b are installed, and the to-be-processed oil 6 is electrolyzed in the tank chamber and a reduction step is performed. The treated oil 6 reduced in the tank chamber 13 is returned to the return pipe 1 as necessary.
After passing through 2b, it is returned to the hopper 10 again.

An alternating current is normally applied to the pair of electrodes 14a and 14b of the present invention, and a high-frequency alternating current of 30 to 50 kilohertz is alternately applied at a voltage of 10 to 50 volts. It is also possible to provide a ground electrode as needed.

Such high-frequency alternating current supplies a high-frequency signal of a high-frequency oscillator to a high-frequency switching command circuit, which supplies a high-frequency switching command to the high-frequency switch, and turns the high-frequency switch on and off at a high cycle. Then, an output from a DC power supply is given to the electrodes.

When a high-frequency alternating current is applied between the electrodes 14a and 14b, a direct current flows between the two electrodes via the oil to be treated 6 in the tank chamber 13 and a rectifying action of the oil is performed. In a few minutes, bubbles of hydrogen atoms are generated in the oil, electrons flow through the pair of electrodes, the oxidation potential of the oil decreases, and a reduced oil is obtained.

According to the oxidation potential experiment of the inventor, the value was +350 mV before the treatment, but after the treatment for about 1 hour, the value was reduced to show an oxidation potential of -200 to -300 mV.

According to the oxidation value experiment of the present inventor, 20
When the liter of the oil to be treated 6 was subjected to the reduction step in the waste oil recycling machine 3 for 90 minutes, the oxidation value of the oil dropped from +5 (before the treatment) to +2 (after the treatment). This determination was based on a test paper of "High Sensitivity Shortening Monitor" manufactured by Sumitomo 3M Limited. When the oxidation value of this test paper shows +3,
It means that the oxidation of the oil has increased and the viscosity has also increased, and that it is time to replace the oil.

The oil 6 to be treated sent by the feed pipe 12a is returned to the return pipe 1 by shortcut in the tank chamber.
In order not to go directly to 2b, tank chamber 13
A baffle plate 15 is installed in the inside, and a passage hole 16 is formed in a part of the baffle plate 15. In the present invention, since the passage hole 16 is formed at the position of the baffle plate corresponding to the position away from the suction port of the return pipe 12b, the oil to be treated 6 can continue to flow without stagnation in the tank chamber 13,
An effective reduction step will be performed.

The oil 6 to be treated after the reduction step can be taken out from either the drain cock 17a in the tank chamber or the drain cock 17b in the hopper.
The removed regenerated oil can be reused as it is or mixed with new oil, as a new frying oil.

[0024]

As described above, according to the present invention, it is possible to extend the life of the oil by delaying the progress of oxidation of the oil and to efficiently regenerate the used oil, even in a normal use state. This has excellent effects such as preventing waste of waste oil and significantly reducing the cost of disposal of oil. Further, the present invention is not limited to frying oil, other industrial machine oil,
There is a feature that can be applied to reduction processing of automobile engine oil and the like.
