PROBLEM TO BE SOLVED: To provide a wet snow generation method and a wet snow generation device capable of making dry snow efficiently flow out from a flow channel as wet snow of a desired water content without attaching to an inner face of the flow channel, in transporting the dry snow on air stream by utilizing the flow channel.SOLUTION: A wet snow generation method has a stage for transporting dry snow toward an outflow opening on transportation air stream at a prescribed speed or more in a flow channel, a stage for supplying hot air of a prescribed temperature and a prescribed humidity into the flow channel from the circumference of an outer peripheral face of the flow channel on the upstream side of the outflow opening, a stage for forming an atmosphere of uniform temperature sufficient for melting the dry snow in the flow channel by uniformly mixing the transportation air stream and dry snow, and the hot air in the flow channel, and a stage for exchanging heat between the transportation air stream and dry snow, and the hot air until reaching the outflow opening in the atmosphere, thus the wet snow is blown off from the outflow opening by preparing the wet snow by melting the dry snow while transporting the dry snow on the transportation air stream.SELECTED DRAWING: Figure 1 |
