| 摘要 | PURPOSE: To increase the quantity of produced snow and also to produce the snow of excellent quality being dried and formed in powder, by providing an ultrasonic oscillator for emitting an ultrasonic wave toward water droplet groups which are jetted by a jetting device for jetting water in atomization from a nozzle. CONSTITUTION: Water is jetted in atomization from a nozzle 3 at an ambient temperature of 0°C or below, water droplet groups 5 jetted are frozen and thereby snow is produced. On the occasion, an ultrasonic wave 6 is emitted toward the jetted water droplet groups 5 from an oscillator 2. COPYRIGHT: (C)1991,JPO&Japio |
