The vortex tube 150 is a product applied by the George Rank of France in 1928 using the hydrodynamic principle throughout the industry. When supplied with -10 Kg / Cm ² , ultra low temperature air (up to -65 ° C) is generated in a very short time.

Referring to FIG. 8, the principle of the vortex tube is that when compressed air is first supplied to the vortex tube 150 having a cylindrical shape through a pipe, the vortex tube is first injected into the vortex rotation chamber to perform high speed rotation. The rotating air is directed in one direction along the tangential direction in the cylinder, and some air is returned from the spindle and exits in the other direction. At this time, the returned air is located at the center of the cylinder, thereby reducing the area of lower pressure. As it passes, it loses calories and generates cold air.

That is, in two rotating air streams (same direction, same angular velocity rotation), the air particles in the inner stream have the same rotational time as the air particles in the outer stream (same angular velocity), so the actual movement speed is lower than the outer flow. . This difference in kinetic speed means that the kinetic energy is reduced, and this lost kinetic energy is converted to heat, raising the temperature of the air in the outer stream and lowering the temperature in the inner stream.

In the case of employing the vortex tube 150 as described above, it not only enables the storage of the refrigerated storage food, but also eliminates the inconvenience of refrigerated storage and heating again.
