It is heated to a predetermined transport temperature (predetermined temperature higher than 0 ° C.) that can slightly melt the surface layer portion of the ice and snow 60 flowing through the transport space 30c.

In this way, the inner peripheral surface 30a of the ice and snow transport pipe 30 is
Is heated to the above-mentioned transport temperature, then, the conveyor 15 installed between the ice storage 13 of the ice and snow manufacturing apparatus 10 and the ice and snow extrusion device 1 of the ice and snow transport apparatus 18 is operated to operate the ice storage 13 The small blocks of ice and snow 60 stored in the ice and snow extrusion device 1 are conveyed to the ice and snow extrusion device 1 by the conveyor 15.
In addition, the conveyed small-sized ice-snow 60 is supplied as a snow-spraying material through the ice-snow intake port 1a of the ice-snow extrusion device 1. At the same time or prior to this, the ice and snow extrusion device 1 is operated. Then, the small-sized ice-snow 60 supplied to the ice-and-snow extrusion device 1 is extruded and ejected by the ice-and-snow extrusion device 1 in a form of being mechanically extruded from the ice-and-snow ejection port 1b. Ice and snow 60
2 is, as shown in FIG.
In a form in which c is densely filled (hereinafter, referred to as "full flow state"), the ice-snow extrusion device 1 to the ice-snow transport pipe 30 transport space 3
0c is supplied. By the way, since the inner peripheral surface 30a of the ice-snow transport pipe 30 is warmed to a predetermined transport temperature over the entire length, the ice-snow 60 supplied in the form of being pushed into the transport space 30c in a full-flow state is Of the 60, the surface layer portion of the ice and snow 60 that comes into contact with the inner peripheral surface 30a of the ice and snow transport pipe 30 is slightly melted. As a result, a thin water layer is formed between the inner peripheral surface 30a of the ice and snow transport pipe 30 and the ice and snow 60 supplied in a full flow, and the thin water layer serves as a lubricant. In order to prevent the ice and snow 60 from adsorbing to the inner peripheral surface 30a, the ice and snow 60 and the inner peripheral surface 30 of the ice and snow carrier pipe 30
The friction force between the ice and snow 60 is reduced, and
It is transported to the slope 70 while passing through the transport space 30c of No. 1 while maintaining a full flow.

As described above, the heating device 20 heats the inner peripheral surface 30a of the ice and snow pumping pipe 30 to a predetermined conveying temperature at which the surface layer portion of the ice and snow 60 in contact with the inner peripheral surface 30a is slightly melted. By doing so, the small snowy ice 60 supplied from the ice and snow manufacturing device 10 to the ice and snow extrusion device 1 is discharged by the ice and snow extrusion device 1 so that the ice and snow transportation space 30c of the ice and snow transportation pipe 30 is in full flow. Even if it is mechanically extruded and discharged from the outlet 1b and supplied into the ice and snow transport pipe 30, the ice and snow 60 that comes into contact with the inner peripheral surface 30a of the ice and snow transport pipe 30 is melted, and the inner peripheral surface 30a and the ice and snow 60 are separated from each other. Since a layer of water is formed between the ice and snow in the full-flow state, the frictional force of the formed layer of water is reduced by the formed layer of water, and the ice-snow transport pipe 30 is maintained in the full-flow state. It can be transported to the slope 70. Therefore, the ice and snow 6 supplied from the ice and snow manufacturing apparatus 10
0 is transported to the slope 70 in a full flow in the ice and snow transport pipe 30, so that the ice and snow 60 occupies most of the volume in the ice and snow transport pipe 30, and the density of the ice and snow 60 transported in the ice and snow transport pipe 30 is increased. Therefore, the efficiency of transporting the ice and snow 60 can be improved, and a large amount of the ice and snow 60 can be transferred in a short time on the slope 70.
Can be supplied to. In addition, since the ice and snow 60 is mechanically extruded and discharged by the ice and snow extruding device 1 and is conveyed in the ice and snow conveying pipe 30 in a full state, there is no waste of the pressure of the air compressed and formed by the blower as in the conventional case. Therefore, energy loss is reduced and energy consumption can be reduced. Therefore, ice snow 60 that is artificial snow can be efficiently transported to the slope 70 of the ski resort, and the energy consumption can be reduced.

Further, by heating the ice / snow transport pipe 30 with the hot water 63 produced by using the exhaust heat 69 of the ice / snow production apparatus 10, energy can be effectively utilized and the ice / snow transport pipe 30 is heated. Therefore, energy for a new heat source is not required, and the energy consumption can be further reduced. Furthermore, since the equipment for introducing the energy for the heat source is not required, the structure of the heating device 20 can be simplified and the installation is easy. Furthermore, it becomes possible to spray a large amount of ice and snow 60 produced and stored by the ice and snow making apparatus 10 onto the slope 70 in a short time, and the slope 7 of snow quality suitable for skiing can be obtained.
0 can be formed efficiently. Further, the hot water distribution space 21 formed between the ice and snow transport pipe 30 and the heating pipe 21.
c is vertically divided into a forward path space 22 and a return path space 23, and warm water 63 is caused to flow from the lower forward path space 22 to the upper return path space 23, so that the inside of the ice and snow transfer tube 30 is conveyed, Particularly, the lower portion of the ice and snow transport pipe 30 where ice and snow 60 is likely to accumulate can be further heated, and the ice and snow transport pipe 30 can be heated.
It is possible to effectively heat the ice and snow 60 that is transported inside to the slope 70.

In the above embodiment, the refrigerator 1
Although the inner peripheral surface 30a of the ice and snow carrier pipe 30 is heated to a predetermined carrier temperature by the hot water 63 manufactured by using the exhaust heat 69 of the second condenser 12a, the inner peripheral surface 30a is heated to the predetermined carrier temperature. It suffices if it can be heated to the carrying temperature, the exhaust heat discharged from other devices can be used as the heat source, and warm air can be used as the heat medium. Tube 3
0 may be directly heated, or a heat ray sheet or the like may be attached to the inner peripheral surface 30a of the ice and snow transport tube 30.
