Abstract
The device forms snow from pressurized carbon dioxide fluids. A supply conduit delivers a flow of pressurized fluid. An expansion member attached to the supply conduit contains a plurality of channels for reducing pressure on the fluid and converting the fluid with reduced pressure into a mixed-phase stream of gas and fine snow particles. The channels have an average diameter and an average length of at least twice its average diameter. An agglomeration chamber attached to the plurality of channels agglomerates the fine snow particles by contacting the fine snow particles together.
