Abstract The high gravity field inside a Rotating Packed Bed (RPB) is a promising approach for the intensification of aroma absorption. Using standard wire mesh packing, the rotation has proven to be an additional degree of freedom for an intensified and more flexible process. Further findings showcase an increase of the absorption efficiency of 9 – 14 % using spiral packing, produced by additive manufacturing, compared to a standard wire mesh under equal operating conditions (G = 100 L/min, ω = 2750 rpm). The spiral packing could be operated at remarkably large gas load factors of up to 15.5 Pa0.5 without any evidence of flooding. All in all, the spiral packing is capable of handling larger liquid flow rates for a given volume and might be in particular beneficial for processing viscous or solid containing media like crude fermentation slurries and is one of the preferable solutions for multirotor RPBs.

带有定制阿基米德螺旋填料的旋转填料床中的香气吸收

摘要 旋转填充床 (RPB) 内的高重力场是增强香气吸收的一种很有前景的方法。使用标准金属丝网填料，旋转已被证明是强化和更灵活过程的额外自由度。进一步的研究结果表明，在相同的操作条件下（G = 100 L/min，ω = 2750 rpm），与标准丝网相比，使用增材制造生产的螺旋填料的吸收效率提高了 9 – 14%。螺旋填料可以在高达 15.5 Pa0.5 的非常大的气体负荷系数下运行，而不会出现任何溢流迹象。总而言之，
