取り扱うことができる。According to the present invention, since the water in the mixture is sprayed as the spray water for freezing the particulate layer by spraying the mixture of the particulate frozen matter and water, when the frozen particulate layer is formed. The step of spraying water on the granular material layer, which is necessary for the above, is unnecessary. In particular, when sprinkling supercooled water to sprinkle the granular frozen matter, an ice-making machine is not required, and even the sprinkling of the granular frozen matter can be handled as a liquid advantageous for pipeline transportation and the like.
