The invention relates to a process for producing solid seed particles comprising an edible fat, the process comprising the steps of (a)providing a flow of edible fat, the edible fat having an outset temperature (OT), (b)in a crystallization zone (CZ) performing a crystallization at a decreased temperature (DT) in a crystallization period (CP) of 1-150 seconds, (c)feeding an output from the crystallization zone (CZ) into a transformation zone (TZ), (d)in the transformation zone (TZ) performing a transformation of crystals produced in step (b) into higher melting crystal polymorphic forms at transformation temperature (TT) above said decreased temperature (DT) to obtain a transformed edible fat and (e) particulating said transformed edible fat into solid seed particles by at least cooling the edible fat processed according to step (d) to a temperature below which the edible fat solidifies.
