摘要:
The present invention provides method and an apparatus for forming particles using supercritical fluid. A load material is mixed with a first flow of supercritical fluid in first mixing chamber (110) having primary mixing device (180) to form a melt. The melt is transferred to second mixing chamber (120) having secondary mixing device (200) to form a lower viscosity melt and then expanded across a pressure drop into an expansion chamber (130) that is at a subcritical pressure of the supercritical fluid to thereby precipitate the load material in the form of particles.
