METHOD OF OBTAINING ARTIFICIAL SNOW FOR AGRICULTURE Russian patent published in 2018 - IPC F25C3/04 

FIELD: machine building.

SUBSTANCE: method for producing artificial snow includes supplying air, water and carbon dioxide under pressure, spraying, mixing these components and discharging them into the atmosphere. Laminar air flow is given by turbulent motion, processed by microwave energy, polarizes chemical elements of air and drops of water from its moisture, supercool, freeze the formed nuclei and the water-air mixture with a jet are thrown into the atmosphere. With the simultaneous action of microwave energy on chemical elements in the air and fine spraying of liquid carbon dioxide, the amount of finely dispersed centers of water crystallization increases, which intensifies the process of snow formation.

EFFECT: method for obtaining artificial snow for air purification and creating an optimal microclimate in livestock and poultry houses, dust suppression in feed mills, factories, grain processing enterprises, for the formation of artificial snow cover of experimental sites in plant growing, protection of gardens and shrubs from frosts during their flowering period, is used in the sanitary protection zones of enterprises that have sources of harmful emissions into the atmosphere.
