PURPOSE:To enhance cleaning effect by providing a compression transfer piping, a compressor, an ice block feeding means and a nozzle means. CONSTITUTION:A nozzle means 6 is inserted into a piping 7 to be cleaned at the time of cleaning. A compressor 1 and an ice block feeding means 5 are actuated and ice blocks are fed into the piping 7 to be cleaned together with compressed air flow. The ice blocks are sprayed out of nozzle opening of the nozzle means 6 at a high speed, collided with the inner surface of the piping 7 to be cleaned and flowed into the piping 7. Adhered matters 8 such as rust and fur are removed by the collision of ice blocks with the inner surface of the piping 7 to be cleaned. The work can be carried out with a high cleaning efficiency by said arrangement. |
