摘要：
The invention provides an apparatus for forming fine particles of a substance in a precipitation chamber, in which the apparatus has means to convey the fine particles from the precipitation chamber to at least one particle collection chamber, downstream of the precipitation chamber, the particle collection chamber having an inlet and an outlet separate from the inlet. The invention also provides a method of forming fine particles of a substance, the method comprising contacting a non-gaseous fluid containing the substance with a dense fluid to expand the non-gaseous fluid in a precipitation chamber, conveying a resulting mixture of fluid and the fine particles from the precipitation chamber to a collection chamber, the collection chamber having an inlet and an outlet separate from the inlet.
