An apparatus for the production of particles of a substance by dynamic
precipitation of the substance from a
fluid solution containing the substance dissolved in a fluid
solvent. The apparatus is characterized by comprising A) a first main flow line FL1 (1) intended for a first pressurized fluid F1 and encompassing in its downstream part (dFL1) (38) one, or more dFL1 sub-lines (1a,b,c), where a) every dFL1 subline • comprises one or two serially linked flow-through dispensers for F1 (5a,b,c. and 6a, b, c) and • is functionally equal to the other dFL1 sublines, and b) each of the dispensers • has an inlet (7a,b,c. and 8a,b,c, respectively) and an outlet (9a,b,c. and 1 Oa,b,c . . . , respectively) for flow, and • is functionally equal with the corresponding dispensers in the other dFL1 sublines, and B) a particle formation arrangement (4) comprising a) one or more flow-through particle formation chambers (3a,b,c . . . ), and b) the downstream dispensers (5a,b,c.) of said one or two dispensers (5a,b,c . . . ,6a,b,c.) with one, two or more dispensers per chamber, at least one of the one or two dispensers (5a,b,c . . . ,6a,b,c.) is an
injector which is capable of being repeatedly activated enabling a pulsed flow through the outlet of the
injector.
