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 【課題】流路を利用して気流に乗せて乾雪を搬送する際、乾雪それぞれを、流路の内面に付着させることなく、効率的に所望の含水率の湿雪として流路から流出させることを可能とする湿雪の生成方法および湿雪の生成装置を提供する。【解決手段】流路内で所定速度以上の搬送気流に乗せて乾雪を流出開口に向けて搬送する段階と、流出開口の上流側で、流路の外周面のまわりから、流路内に所定温度および所定湿度のホットエアを供給する段階と、流路内で、搬送気流および乾雪と、ホットエアとを均一に混合することにより、流路内に乾雪を溶かすに十分な均一温度の雰囲気を形成する段階と、雰囲気内で、流出開口に至るまで、搬送気流および乾雪と、ホットエアとの間で熱交換を行う段階とを、を有し、それにより、乾雪それぞれを搬送気流に乗せて搬送しつつ、溶かして湿雪化して、湿雪を流出開口から吹き出す。【選択図】図１
