ている。As an apparatus for artificially producing such rime ice, for example, an apparatus as shown in FIG. 3 has been conventionally used. The conventional artificial rime generator has a cooling chamber 32 surrounded by a heat insulating wall 31.
An air cooler 33 is provided therein, and the inside of the cooling chamber 32 is cooled to a temperature below freezing point (-30 to -5 ° C) by the air cooler cooling 33, and a two-fluid nozzle 34 to which water and compressed air are supplied from the outside.

う問題がある。[0005] By the way, hoarfrost adheres to the entire surface of the tree, and it is most beautiful that the tree shape is maintained. However, in the above-described conventional apparatus, the convection of cool air in a certain direction is performed by the blower 38 of the cooler 33. There is a problem that hoarfrost is generated on the side where the cool air flows, but not so much on the other side.

て霧氷を再現することができない。[0006] When the convection is suppressed by making the blowing amount of the blower 38 extremely small, the fog falls from above the tree, and the rime is formed on the upper side of the tree, but is almost entirely formed on the lower side and the side surface. Instead, it is impossible to reproduce hoarfrost as snow falls on trees.
