The present invention uses so-called W/O, which is made by dispersing a liquid such as water or vinegar in a dispersion medium liquid such as oil, which becomes a continuous phase.
The present invention relates to a method and apparatus for producing a type emulsion. By mixing liquids such as oil and water that do not dissolve in each other,
Conventionally, to produce emulsions, surfactants and stabilizers are added to act as emulsifiers, and the emulsifiers are coordinated to the interface between oil and water, thereby significantly lowering the interfacial tension and increasing the interfacial free energy. This is done by suppressing the increase. Alternatively, in some cases, an emulsion may be temporarily produced by mechanical stirring. For example, to make salad dressing,
It can be applied by mixing salad oil and an aqueous solution of vinegar, which do not dissolve in each other, using egg yolk as an emulsifier, or the liquid separated into two phases in a container can be temporarily emulsified by shaking and physically stirring just before use. Let them do it and give it to you. Therefore, when using the former emulsifier,
Due to food restrictions, other non-food organic substances cannot be used as the emulsifier, and the use of egg yolk limits the taste. In addition, emulsifiers (surfactants) only slow down the rate of increase in interfacial free energy and extend the time until complete separation, and when using egg yolk, it is difficult to maintain an emulsified state for a long period of time. Can not. In addition, the latter method of stirring is effective only when achieving an emulsified state for an extremely short period of time.
It is unbearable to have to stir it every time it is used. As described above, conventional emulsification methods have various drawbacks and limitations. By the way, in the case of so-called W/O emulsions where water etc. are dispersed in oil such as the salad dressing mentioned above, the oil serving as the dispersion medium is poorly conductive, and the water etc. serving as the dispersed phase is conductive. Therefore, if fine particles such as water are charged with static electricity of the same polarity, each dispersed phase fine particle will repel each other, and the fusion of the dispersed particles with each other, which is the liquid layer separation process, will be prevented. ,
It is thought that the emulsified state continues for a long period of time because it is insulated and maintained by the oil. The present invention is based on the above findings and aims to provide a new method and apparatus for producing an emulsion that does not necessarily require an emulsion. An embodiment of the invention will be described with reference to the accompanying drawings. A spherical recovery tank 2, which has a recovery flow pipe 4 on the bottom that allows collection of an appropriate amount by means of a valve 3, is fixed to a support column 1, and the recovery tank 2 is electrically grounded. The recovery tank 2 is alternately provided with a large number of sprayers 5 for spraying oil and sprayers 6 for spraying a liquid such as water that does not fuse with oil. The sprayers 5 and 6 may be either airless type or air type, and known sprayers used for electrostatic coating can be used. The sprayer 5 is supplied with oil by an airless pump 9 from a storage tank 7 through a pipe 8, and the opening and closing of the valve is controlled by an air-operated valve or the like. The pressure turns the oil into fine particles and squirts it out. The atomizer 5, reservoir 7, airless pump 9, etc. are grounded to prevent electrical charge from being generated in the ejected oil. The sprayer 6 is also connected to the pipe 1 from the storage tank 10.
A liquid such as water is pumped through the pump 1 by an airless pump 12, and the water or the like is pulverized and ejected. A high voltage of 2 KV or more is applied to the liquid by a DC high voltage generator 13 at either the positive or negative pole. The storage tank 10, the airless pump 12, and its pressure-feeding pipe 11 are each insulated to prevent the current from leaking. The spray ports of the sprayers 5 and 6 are each directed into the recovery tank 2, so that the atomized oil and water sprays ejected from the sprayers 5 and 6 collide near the center of the recovery tank 2. , mixes well by its jet power. The liquid collected into the recovery tank 2 while being mixed is further mixed within the recovery tank by the mixer 14, and fine particles such as water are uniformly dispersed in the oil. As described above, the dispersed phase fine particles such as water, which are mechanically dispersed in oil, are charged with static electricity of the same positive or negative polarity by the voltage application by the DC high voltage generator 13. Therefore, a repulsive force acts between each fine particle, and fusion of dispersed particles caused by Brownian motion of fine particles or the like is prevented. At this time, oil has poor electrical conductivity and maintains the charged state of the dispersed phase fine particles by electrically insulating them from the outside, so that the dispersed phase fine particles such as water are contained in the dispersion medium such as oil. The dispersion state is maintained for a long period of time to produce an emulsion. The relationship between the separation time of the emulsion produced using the above-mentioned apparatus and the applied voltage is shown below.

In order to further extend the separation time, known emulsifiers may be used in combination. As clarified in the above description, the first invention uses a poorly conductive dispersion medium liquid such as oil and a conductive dispersed phase liquid such as water that is charged with static electricity of the same polarity by applying a high voltage. By atomizing each particle and causing the respective spray streams to collide with each other, the dispersed phase particles are mechanically dispersed in the dispersion medium, and the electrostatic repulsion prevents the particles from coalescing and agglomerating, resulting in a long-term Because it produces a stable emulsion, it is possible to produce an emulsion without using an emulsifier.For example, when producing foods such as salad dressings, there are no restrictions on taste due to the addition of emulsifiers, and food contamination caused by emulsifiers. In addition, since the emulsion is produced solely through physical operations, it has excellent effects such as simple equipment and low manufacturing cost. Further, the second invention uses a sprayer 5 such as the one normally used in electrostatic coating to spray the dispersion medium and the dispersed phase.
The first invention can be carried out by atomizing the particles and colliding the spray stream on the recovery tank 2, which has excellent effects such as a simple device and suitable for mass production.
