である。2. Description of the Related Art Conventionally, in the food industry, the chemical industry, etc., a large amount of a first liquid has been uniformly mixed with a small amount of a second liquid. To do. As a method of degumming crude crude oil of vegetable oil (eg, soybean oil, rapeseed oil, corn oil, cottonseed oil, sunflower oil, etc.), 2 to 5% of water is added to the crude crude oil, and the mixture is stirred and mixed by a mechanical stirrer. By dispersing the water in the crude oil as fine particles, the hydrophilic lecithin in the oil is hydrated and aggregated, and then the hydrated aggregate is separated by a centrifuge or the like to give a gum in the crude oil. The method of separating (lecithin) is adopted. In such a degumming method, the degree of degumming depends on the dispersibility of water in crude oil, and uniformly dispersing water in the crude oil as extremely small particles improves the degumming rate. It is valid.

が図れる等のため極めて望ましい。However, in the conventional dispersion of water by only mechanical stirring, there is a limit to the improvement of dispersibility, and the degumming rate obtained as a result is not completely satisfactory. In the oil refining process, the improved degumming rate facilitates the subsequent refining process, reduces the amount of chemicals used, and reduces the oil loss, thus improving the oil yield and comparing with oil. It is highly desirable because it can increase the production of expensive lecithin.

するが、依然として満足すべき程には向上しなかった。In order to improve the degumming rate, the dispersibility of water in crude oil is improved. Therefore, it is known that after mixing water with crude crude oil, the mixed solution is sent to an ultrasonic horn and ultrasonic vibration is applied by the ultrasonic horn to improve the dispersibility of water. For example, J. Am. Oil Chem. Soc. 66 89

とを見出し、本発明を完成した。Means for Solving the Problems As a result of intensive studies by the present inventors for improving the dispersibility of water by means of an ultrasonic horn, even if ultrasonic vibration is applied to crude crude oil after mixing it with water, the dispersibility is not so great. Although not improved, it was found that the dispersibility of water is extremely improved by supplying water to the crude oil that has been subjected to ultrasonic vibration by an ultrasonic horn at a position where it is subjected to strong ultrasonic vibration, completed.

液体混合方法を要旨とする。That is, according to the present invention, in a method of mixing a small amount of a second liquid with an ultrasonic wave by using an ultrasonic wave, the first liquid is supplied so as to pass through a vibration surface of an ultrasonic horn, At the same time, the gist of a liquid mixing method is characterized in that the second liquid is supplied into the first liquid at a position close to the vibration surface of the ultrasonic horn.

In order to apply the vibration, it is preferable to provide a first liquid supply path so as to be opposed to the vibration surface of the ultrasonic horn and to supply the first liquid so as to abut against the vibration surface through the opening. On the other hand, the second liquid forms a second liquid supply path so as to open facing the vibration surface of the ultrasonic horn,
The liquid is supplied from the second liquid supply passage so as to hit the vibrating surface, or the second liquid supply passage is formed in the ultrasonic horn so as to open to the vibrating surface, and the liquid is supplied through the second liquid supply passage. Is preferred. When the second liquid supply path is provided separately from the ultrasonic horn, its opening is located in a portion where the energy of ultrasonic vibration is high, and therefore, usually within 10 mm from the vibrating surface of the ultrasonic horn, preferably,
It is preferable to arrange it in a portion within 5 mm.

The second liquid meets and is mixed. Thereby, as compared with the method using the ultrasonic horn described in the above-mentioned document, the second liquid enters into the first liquid as finer droplets, and the mixing property is improved. That is, when the second liquid is insoluble in the first liquid, the second liquid becomes extremely fine particles and is dispersed in the first liquid, and the dispersibility is improved. When the second liquid is soluble in the first liquid, the second liquid becomes extremely fine particles and is mixed in the first liquid, thereby increasing the contact area between the two liquids, Dissolves quickly and uniformly.

る。As compared with the case where the premixed first liquid and the second liquid are passed through the vibrating surface of the ultrasonic horn and ultrasonic vibration is applied to the vibrating surface of the ultrasonic horn, the second fluid is provided near the vibrating surface of the ultrasonic horn. The reason why the mixing property is improved when the above is supplied to the first fluid is considered as follows. That is, when the first liquid and the second liquid are mixed in advance, the second liquid becomes droplets of a certain size and is dispersed in the first liquid, and the ultrasonic horn The liquid droplets are hard to break even when ultrasonic vibration is applied, especially when the water droplets are surrounded by agglomerates such as when water is mixed in crude crude oil. Although it is difficult to obtain droplets, when the second liquid is supplied into the first liquid at the part that is subjected to strong ultrasonic vibration, the discharged second liquid immediately becomes extremely fine particles due to ultrasonic vibration, and the state It is considered that this is because it enters the first liquid.

Therefore, there is an extremely high probability that water will encounter lecithin in crude oil, and most of lecithin can be hydrated and aggregated. Then, by removing the hydrated aggregates, the degumming rate is higher than in the past. It can be greatly improved.
