First, the aroma water prepared to have a concentration of 10 to 100 mg / liter is put into the contact tank 6. As this aroma water, any water can be used as long as it contains aroma components in the form of a suspension, a mixed liquid or an aqueous solution. Generally, many aromatic components are oil-soluble, and alcohol or the like is often used as a solvent. When a solution of such a fragrance component is added to water, it is partially dissolved, and most of it is present in the form of a suspension or a mixed liquid in water. As a general aromatic odor,
Rose, jasmine, lavender, aroma of flowers such as oysters, scent of trees such as cypress, citrus scent, etc. are used for perfumes, bath agents, fragrances, etc. Those having these aromatic odors can be preferably used. Next, the temperature of the aromatic water in the contact tank 6 is preferably set to about 20 to 80 ° C. by the heater 25, the pump 23 of the aromatic water supply means 3 is driven, and the plurality of solution spray nozzles 5 arranged in the contact tank 6 are driven.

Here, the amount of white smoke generated can be adjusted by adjusting the amount of liquid nitrogen sprayed by the control valve 13.

The liquid nitrogen sprayed from the liquid nitrogen spray nozzle 4 comes into contact with the spray particles of the aromatic water filled in the contact tank 6 to generate white smoke, and at the same time, carries the aroma component to produce aromatic white smoke. And is discharged from the discharge port 7. The aroma solution storage tank 41 contains a concentrated liquid of an aromatic agent containing an aromatic component at a concentration higher than that of the aromatic water in the contact tank 6. Open it up,
By supplying the concentrated liquid of the fragrance agent from the fragrance solution storage tank 41 to the contact tank 6, the concentration of the fragrance component in the fragrance white smoke can be increased.

In general, the characteristics of white smoke vary depending on the temperature of the white smoke itself, and for example, high temperature white smoke becomes rising smoke,
Cold white smoke tends to fall into falling smoke. Therefore, it is possible to generate scented white smoke having specifications according to the situation of use, such as drifting or rising scented white smoke.
Therefore, the scented white smoke can be used not only for obtaining a scented atmosphere, but also for various plays, shows, events and the like, and it is possible to develop the production in various ways. Furthermore, the supply pressure of liquid nitrogen and the driving force by volume expansion accompanying the phase change from liquid to gas promote the diffusion of scented white smoke, and a scented atmosphere can be suitably created in a wide range. In addition, the diffused state of the fragrance component can be visually confirmed as the state of white smoke.

In the above example, the aroma water and the liquid nitrogen are brought into contact with each other in a sprayed state, but the method is not limited to such a method, and the aroma water and the liquid nitrogen are simply brought into contact with each other. However, it goes without saying that a sufficient amount of aromatic white smoke is formed. Further, in the above example, the case where the aromatic water is sprayed has been shown, but a nozzle that sprays only water and a nozzle that sprays the liquid fragrance are provided in the contact tank 6, respectively.
You may make it these spray particles mix in the space in the contact tank 6.
