    • A method for micronization of a dispersion of particles comprising a protein having a predetermined level of biological activity. The method comprises introducing the dispersion into a vortex chamber milling apparatus under milling conditions which result in a protein powder having a particle size distribution of 5 to 100 µm and/or exhibiting a 30 to 400 fold size reduction of the protein particle dispersion from its original size, and retaining at least 80% of the predetermined level of biological activity of the protein. The milling conditions include one or more parameters selected from the following: input pressure between 1 and 7 Bars; injector pressure between 0.2 and 5 Bars; loading rate between 0.1 and 5 kg/hour; and gas flow between 30 and 100 m 3 /hour.
    • 包含具有预定水平生物活性的蛋白质的颗粒分散体的微粉化方法。 该方法包括在研磨条件下将分散体引入涡流室研磨装置中,其导致蛋白质粉末的粒度分布为5至100μm,和/或显示蛋白质颗粒分散体从其原始的30至400倍大小的尺寸 并且保留蛋白质的预定水平的生物活性的至少80%。 研磨条件包括从以下选择的一个或多个参数:1和7条之间的输入压力; 注射器压力在0.2和5条之间; 装载速度在0.1到5公斤/小时之间; 并且气体流动在30和100m 3 /小时之间。
