The expanding agent is then added to one at a supercritical pressure and the flows are mixed. This mixture can then be extruded through holes in a cylindrical die 37 which are provided with knives to separate the extrusion into granules. A nozzle 13 directs a liquid jet at the die and an inlet 14 feeding a gas to the cutting chamber prevents it flooding.
