Abstract: An apparatus for forming solid carbon dioxide blocks comprises a chamber with an internal cavity, a flow control valve including a variable area orifice, an actuator configured to control the area of the variable area orifice and a controller configured to vary the are of the variable area orifice while liquid carbon dioxide is being flashed to solid carbon dioxide snow through the flow control valve. A method of forming carbon dioxide blocks comprises the steps of varying the area of an orifice while flowing liquid carbon dioxide through the orifice under sufficient pressure to flash the liquid carbon dioxide to solid carbon dioxide snow.
