Abstract
A method for artificial making of snow by a snow making machine (1) comprising a series of nozzles (8) arranged to provide a tubular flow (2) of bulk water drops which are moved along by an inner flow (3) of feeder air, and a series of atomizing nozzles (10) arranged to provide a flow of super cooled nuclei which are created at or adjacent the outer periphery (9) of the snow making machine (1) by a series of atomizing nozzles (1) which are distributed round the snow making machine and radially outside and preferably downstream the bulk water jet nozzles (8) as seen in the flow direction, whereby there is formed a shell (5) of super cooled nuclei extending circumferentially round the flow (2) of bulk water drops, which successively, and over a relatively long way of movement provides a freezing of the drops of water in the flow (2) of bulk water drops.
