ARTIFICIAL SNOW PRODUCTION PLANT FOR AGRICULTURAL NEEDS Russian patent published in 2020 - IPC F25C3/04 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, in particular to equipment for production of artificial snow. Plant for production of artificial snow for agriculture contains axial channel communicating successively air pressure supply means (1), Laval nozzle (2), microwave chamber (3) with microwave energy generator (4), water (7) and liquid carbon dioxide (8) supply device, mixing chamber (5), jet nozzle and diffuser (6). Centrifugal nozzle (12) is installed on cover of mixing chamber. In the lower cylindrical part (14) of the centrifugal atomizer there are two tangential channels (17) arranged symmetrically and interconnected with the mixing chamber by conical guides with taper angle not exceeding 45°. In cylindrical hole of upper conical part (15) of pump housing (13) there are external (19) and internal (20) thin-walled cones, which form cylindrical nozzle (21) with gap of 4–5 mm and conjugated with it conical nozzle (22), varying by height with clearance at output of 1–2 mm, with root angle of centrifugal nozzle, not exceeding 42–56°.

EFFECT: increased intensity of snow formation.
