    • The invention relates to an Internal mix atomizing spray nozzle assembly (1), in particular for preparing a spray-dried lipid and protein component-containing composition, comprising a fluid nozzle with a liquid flow passage having a liquid discharge opening directed into a mixing chamber a spray tip (3) comprising the mixing chamber and having at least one discharge orifice (18) at its free end, an air supply system comprising an annular air flow passage arranged at least essentially coaxial to the liquid flow passage and having an annular air discharge opening directed into the mixing chamber. It is planned that the annular air flow passage is designed cylindrical with a constant cross section. For further reducing fouling, a outer surface of the spray tip may be at least essentially cylindrical and may comprise an edge (19) at its free end where the at least one discharge orifice (18) is arranged, and a plurality of recesses (21) in the outer surface of the side wall (8).
    • 本发明涉及一种内部混合雾化喷嘴组件(1),特别是用于制备喷雾干燥的含脂质和蛋白质组分的组合物,其包括具有液体流动通道的流体喷嘴,该液体流动通道具有引入混合室 包括所述混合室并且在其自由端具有至少一个排出孔(18)的喷嘴(3),空气供应系统,包括至少基本上与所述液体流动通道同轴的环形空气流动通道,并且具有环形空气 排出口进入混合室。 计划环形空气流通道设计为具有恒定横截面的圆柱形。 为了进一步减少污垢,喷嘴的外表面可以至少基本上是圆柱形的,并且可以包括在其自由端处布置有至少一个排放孔(18)的边缘(19)和多个凹部(21) )在侧壁(8)的外表面中。
