Abstract:
1. A machine for producing an evaporative snow as small individualized particles which are easily dispersed, are free from agglomerates and leave no moisture and residue in the area of use, said machine comprised of a pump to deliver evaporative snow solution to a flake generator comprising of an impeller or impellers which causes the flakes to form on the surface of a sock, said flakes are dispersed by a sock by a airflow of 500-3000 cubic feet per minute, created by said impeller(s) and produces external noise level up to around 90 decibels measured three feet from the machine wherein external noise is reduced through: (a) direction air flow to a plastic duct: (b) sealing the duct with acoustical foam; (c) containing the fan in the duct in a non rigid mounting; (d) and by using special sized and shaped foam baffles to reflect and absorb noise energy, that are rotated to counteract a particular fan frequency.
