PURPOSE: A snow ice making device is provided to include a characteristic refrigerant circulating device of an ice making drum which is integrated in a coupling shaft. CONSTITUTION: A member circulating refrigerant inside an ice making drum comprises a coupling shaft(40) bundle, a refrigerant jetting capillary tube pipe arrangement structure, and an exhaust pipe arrangement structure. Refrigerant jetting capillary tube pipes(20) and a refrigerant gas exhaust pipe(30) are arranged in a central passage(41) and welded to be integrated so that the central passage of the coupling shaft bundle is closed. The refrigerant jetting capillary tube pipe arrangement structure is as follows. The refrigerant jetting capillary tube pipes including a terminal unit(22) arranged near to a jetting position inside a cooling drum are gathered in the central passage, extended to the outside of a cooling drum, and directly connected to a refrigerant supply pipe of a refrigerant compressor in a multi-connecting unit(21). The exhaust pipe arrangement structure is as follows. The exhaust pipe connected to a multi-intake pipe(33) inside the cooling drum is extended to the outside of the ice making drum via the central passage and directly connected to an intake pipe(54) of a condenser in a connection unit(31). |
