Neddykningsbeholder til pelletering af farmaceutiske opløsninger

摘要

Pelletizing of liquids or pastes comprises feeding them into a tank of coolant, especially liquid nitrogen (16). A stream of gas (15), especially sterile nitrogen, is passed into this to agitate it or produce turbulence. An independent claim is included for apparatus for pelletizing liquids or pastes comprising a feed (4) for the liquid or paste and a gas feed system (3) which passes it into the coolant.
