Description

Oil detection device

This creation is about an oil detection device, especially a kind of detection of oil stability, which can be determined in a very short period of 10 hours, and saves time materials and medicines, and can be changed according to POV value and fixed value. In order to judge the advantages and disadvantages of different oil products, the device can be selected according to the selection of the product formula, and the manufacturer can provide accurate cost calculation and a device for making high-quality blending oil and multi-effective oil products.

In recent years, a series of oil safety incidents involving mixed oils and improper mixing of additives have caused the people to smell the oil. These problems have previously been tested by oil products, and it is impossible to distinguish the quality of oil products in a short time. Time-consuming materials, and not true. This creation is based on the inspection of the common law, the selection of the target oil formula, and the screening of different oil quality ratios, it can be resolved in a short time, without the need of a huge database and higher technology instruments.

For the oil and fat industry, the so-called "stability test" has been carried out for many years, that is, the AOM test, which is based on the POV (peroxide price), and the POV has a correlation with the quality of the oil. The apparatus for measuring the AOM is air as the venting material. It is necessary to remove the "nitrogen" in the air and use the oxygen component to enter the grease to assess the stability of the grease based on the "time" of the POV100. The longer the time, the more stable it is. On this basis, it is ignored. When the oil is oxidized into peroxide oil, the higher the POV, the faster the cleavage will be, the POV will decrease, and the relative acid value (AV) will increase. If the POV falls during sampling, it will cause sampling. There is an abnormal analysis value of POV, reaching The 100POV value takes a long time and wastes oil and materials. This is one of the disadvantages. Secondly, the device must use multi-tube aeration. The concentration of nitrogen and sulfuric acid in the ventilation depends on the time, and the concentration becomes light, which affects the oxygen concentration in the gas stream. The rate also changes, and the time at which the AOM reaches the 100 POV value becomes an untrustworthy variable.

Furthermore, whether fats and oils can be eaten is closely related to the degree of oxidation and the taste produced. Generally speaking, when the POV reaches 30meg/KgPOV, the fuel consumption is already generated, and it has been judged to be inedible. In this fashion, POV degradation does not occur. Function (phenomenon), so it is a very good criterion for the value of oil and fat. However, if the POV is to reach 100, there is no degradation in the middle. Therefore, it is determined by the time (100) of 100 hours. Whether it is stable or not is an unreasonable and unrealistic test method.

Generally, the traditional AOM POV inspection device is complicated and uneconomical. Among them, the air flow rate and the use of 1% sulfuric acid and 2% potassium dichromate solution in the device to remove nitrogen, it is often found that the nitrogen removal effect is reduced during each operation. It must be changed once. If you forget to change the liquid, the pure oxygen in the air is not easy to obtain, resulting in an inaccurate test value. In the test process, a large number of test tubes are used, which wastes oil and electricity.

In view of this, the applicant has continuously researched and experimented to design an oil detection device to make the oil inspection more convenient and the inspection value more accurate.

The main purpose of this creation is to provide an oil detection device that makes oil inspection more convenient, short operation time and more accurate inspection value. It can be applied to oil formula to develop new high quality blending oil. And the development of prescriptions for oil additives (such as antioxidants), can be used as an experiment to compare the quality of different oil products.

The foregoing oil detecting device comprises a sampling tube, a fixed group seat, and An oil filled test tube and a heating device. The sampling tube is disposed in the fixed group seat, and the fixed group seat is provided with an air inlet and an air outlet.汲 适 适 适 适 适 俾 俾 俾 俾 俾 俾 俾 俾 俾 俾 俾 俾 俾 俾 俾 俾 俾 俾 俾 俾 俾 俾 俾 俾 俾 俾 俾 俾 俾 俾 俾 俾 俾 俾 俾 俾 俾 俾 俾 俾 俾 俾 俾 俾 俾Pure oxygen to the oil-filled test tube, so that pure oxygen continues to flow in the oil-filled test tube to increase the oxidation rate of the oil to be tested, and detect the POV (peroxide price) value at a fixed time, thereby making the oil test more It is simple and can detect the stability of these oils in a very short period of 10 hours.

Please also refer to Fig. 1 and Fig. 2, together with Fig. 3, which is an exploded perspective view and a perspective view of the detection device of the present invention, and a cross-sectional view. As shown in the figure, the detection device of the present invention includes at least one sampling tube 1 a fixed base 2, and an oil filling tube 3 and a heating device 4. The top of the sampling tube 1 is provided with a cover body 11 . The top edge of the fixed base 2 is provided with a cover 11 corresponding to the sampling tube 1 , and has an opening 21 with a thread 211 , and two sides are provided with an air inlet 22 . The air outlet 23 is provided with a cover body 24 at the bottom, and the oil filling tube 3 is provided with a thread 311 corresponding to the cover body 24 of the fixed base 2 at the nozzle 31.俾The sampling tube 1 is opened by the opening 21 is inserted into the fixed base 2 and locked by the cover 11 to the opening 21, and after taking an appropriate amount of the oil to be tested 5 by the sampling tube 1, the sampling tube 1 is placed in the oil filling tube 3, and the cover is placed. The body 24 is locked to the nozzle 31 of the oil-filled test tube 3, and is in a gas-tight state, and is disposed between the lid body 24 and the opening 31 of the oil-filled test tube 3, and is provided with a gasket 32.

Please refer to FIG. 4 , which is a detection state diagram of the present invention. Please refer to FIG. 3 , as shown in the figure, the oil-filled test tube 3 containing the oil to be tested 5 is placed in the heating device 4 . The heated medium can be a relatively stable oil, and the intake pipe 22 of the fixed block 2 is connected to an oxygen supply device 6, and the oxygen supply device 6 is filled with pure oxygen into the oil filling tube 3, and then The gas outlet 23 is released, and if necessary, a gas flow meter can be connected to check whether the flow rate of the pure oxygen input of each of the oil-filled test tubes 3 is consistent with the amount of pure oxygen input to the original plan. The heating device 4 can accommodate a plurality of oil-filled test tubes 3 at the same time, so that the oxygen supply device 6 simultaneously injects pure oxygen into the respective oil-filled test tubes 3 for experiments for comparing the quality of different oil products.

As described above, this creation has at least the following advantages over the conventional oil detection method:

1. The present invention is to install a sampling tube 1 in the same oil-filled test tube 3, and the same oil product is the same oil-filled test tube 3 throughout the inspection process, and the oil sample analysis of the different oil-filled test tubes 3 can be analyzed in the whole process. Sex (traditional testing methods will vary), so this creation has a fairly accurate analysis value.

2. Each oil-filled test tube 3 requires only 50~60ml of oil sample. When the initial sampling is 5ml, only 3~4ml should be sampled in the second hour, 42ml in the fourth hour, and the sixth to tenth hour. A 1 ml downsampling sample is required, which is in line with the principle of oil sampling.

3, each of the oil-filled test tubes 3 represents an oil sample, such as a variety of oil samples at the same time Work and inspection, which is very "comparative" effect, and only need 50~60ml each, while the traditional inspection method (AOM) requires multiple tubes at one time, not only the fuel consumption is increased, but only one oil sample can be analyzed, which is too wasteful. Oil analysis of drugs and manpower.

Another function of this creation can be used as a grease formula or an antioxidant formulation experiment. It is a versatile experimental device, such as flow control, one-time test, it is very easy to judge the storage time of oil, for example: 95 When heated at °C, the flow rate of pure oxygen is 0.2~0.5ml per second, the thermochemical reaction is 128 times the reaction rate of normal temperature (25°C) (called abusive test), and the ratio of air oxygen to pure oxygen is 5 times. Therefore, in this experiment, when the POV value reaches 30meg/Kg, the time is 8 hours, and the estimated time for the oil to be exposed to the air is 128×5×8h/24h=213.3 days (the life time of the exposed air). If the listed oil has been marked for 2 years, the results of this test are comparable. If the sample oil is the same as the commercial oil, the quality and life are more similar.

If the sealed oil is placed at room temperature (due to the rare amount of oxygen in the bottle), it should have several times of life. Therefore, in a short time of 8~12 hours, you can know the quality of the oil and the length of life. General AOM The test method cannot predict the storage time.

The foregoing embodiments are merely illustrative of the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and the details of the present invention are not deviated from the spirit of the present invention.

In summary, the creation of the sample consists of a sampling tube, a fixed set of seats, and an oil-filled test tube, together with a heating device, to form an oil detecting device. It makes the oil inspection more convenient, the inspection value is more accurate, and different oils can be added according to the POV value, so as to make high-quality blending oil. For a practical design, it is a novelty creation, and the application for patents is filed according to law. Check, grant patents as soon as possible, to the sense of virtue.
