Abstract (en)
The present invention proposes an apparatus (20) for mixing a first liquid (12) and at least a second liquid (14) by producing shear and/or cavitation. Said apparatus (20) comprises a premixing chamber (38), wherein a first liquid (12) and at least a second liquid (14) are mixed to form a premix (44), said premixing chamber (38) comprising an inlet (40) from a feed line (32) for a first liquid (12) and at least one inlet (42) from a feed line (34) for at least a second liquid (14). The apparatus (20) further comprises a spray element (64) with an orifice (66) therein forming the outlet (68) of the premixing chamber (38), wherein said orifice (66) is configured to discharge the premix (44) from the premixing chamber (38) in a jet (70) and produce shear or cavitation in the premix jet (70). The apparatus (20) further comprises a mixing chamber (72) with an outlet (74), the mixing chamber (72) collecting the jet (70) exiting the premixing chamber (38) as a mix (24) and discharging the mix (24) through the outlet (74). The feed line (32) for the first liquid (12) at least partially comprises a material (36) with a specific thermal conductivity of less than 15 W/(m*K). The present invention also proposes to use the apparatus (20) to produce an aqueous emulsion or suspension. The present invention further proposes a method for the production of an aqueous emulsion or suspension.
