The can cleaning apparatus 130 can clean both ends of the can C having both ends cut by the can cutting apparatus 120 and can clean the can and the can C using ultrasound So that the remaining contents (drinks and various liquid substances) can be washed and separated.

That is, when the frequency is transferred to the aqueous solution by the ultrasonic device 136, waves are generated inside the aqueous solution and millions of micro-spaces formed as bubbles due to hydrodynamic positive pressure and negative pressure are formed .

At this time, the micro-space is merged or increased for a very short time of about milliseconds, and a shock wave having a high energy of 100,000 atm or more is generated in a fine space.

The contents remaining on the inner surfaces of the can (C) and the can (C) are not in a state of chemical bonding, but the contents are coated on the surface of the glass. When the contents are subjected to high energy generated by the ultrasonic wave, The crystals formed are pulverized and dispersed in an aqueous solution, whereby the contents can be easily separated from the can (C).

Therefore, in the embodiment of the present invention, as shown in FIG. 4, the can cleaner 130 has a predetermined length and an accommodation space formed therein. The can cleaner 130 has an inlet 131a A screw 134 installed in the cleaning housing 132 and capable of transporting the can C and an ultrasonic wave generator 140 installed in the cleaning housing 132. The cleaning housing 132 is provided with a discharge port 131b at the other end thereof, A can cleaning device comprising an ultrasonic device 136 that can generate the can and an air spray device 138 that can spray air to the can C whose contents are separated, Respectively.
