    • Described is a process for evaporating a portion of a colloidal solution, said process comprising: a) passing a colloidal solution, said colloidal solution comprising particles in a liquid medium, wherein at least a portion of said liquid medium comprises at least one volatile component, through one or more orifices into an evaporation zone that has at least one inner surface, wherein said colloidal solution does not substantially contact said at least one inner surface of said evaporation zone as said colloidal solution is passed through said evaporation zone; b) applying pressure in said evaporation zone that is lower than the vapor pressure of said colloidal solution as it is passed into said evaporation zone, allowing for flash evaporation of at least a portion of said at least one volatile component from said colloidal solution; c) adjusting the pressure in said evaporation zone to evaporate an amount of said at least one volatile component from said colloidal solution; and d) collecting the remaining colloidal solution from said evaporation zone.
    • 描述了用于蒸发一部分胶体溶液的方法,所述方法包括:a)使胶体溶液通过,所述胶体溶液包含颗粒在液体介质中,其中至少一部分所述液体介质包含至少一种挥发性组分, 通过一个或多个孔进入具有至少一个内表面的蒸发区,其中当所述胶体溶液通过所述蒸发区时,所述胶体溶液基本上不接触所述蒸发区的所述至少一个内表面; b)在所述蒸发区中施加低于所述胶体溶液进入所述蒸发区时的蒸汽压的压力,从而允许所述至少一种挥发性组分从所述胶体溶液中闪蒸至少一部分; c)调节所述蒸发区中的压力以从所述胶体溶液中蒸发一定量的所述至少一种挥发性组分; 和d)从所述蒸发区收集剩余的胶体溶液。
