Abstract

A method and a device for the production of artificial snow are disclosed. The device is of the kind having a spray assembly (4) which is positioned relatively high above the ground and which comprises nozzles for ejecting pressurized water and air. The spray assembly is directed so that the flow is substantially horizontal. The spray assembly comprises, on the one hand, a central set of bulk water nozzles, providing a central, unitary bulk water stream (B) diverging along the main direction (A) and, on the other hand, a surrounding set of atomizing nozzles ejecting a curtain (C) consisting of air mixed with very small, atomized water drops, so called nuclei, which surround the central bulk water stream. The nuclei freeze into snow particles directly upon flowing out of the atomizing nozzles and merge thereupon with the bulk water stream, so that the snow particles rapidly grow into larger snow particles.
