  • Publication number: 20220300685
    Abstract: A process of assembling a filling system for low volume filling of a liquid into a container is disclosed. The process includes obtaining plural liquid forwarding devices configured to provide the liquid from a reservoir to the container, and simulating operation of each of the liquid forwarding devices by numerically modelling flow patterns of the liquid when being forwarded by the liquid forwarding devices, and by determining a shear stress rate for each of the liquid forwarding devices based on the modelled flow patterns. The process further includes determining an appropriateness for each of the liquid forwarding devices by comparing operation parameters of the liquid forwarding of the liquid forwarding devices, wherein the operation parameters include the determined shear stress rates, selecting the liquid forwarding device having the highest determined appropriateness, and installing the selected liquid forwarding device into the filling system.

  • Publication number: 20220221410
    Abstract: An inspection device (1) has a particle detector (3) adapted to detect particles (5) in a liquid, a seat (6) adapted to position a container (4) housing the liquid in an area of operation (311) of the particle detector (3) and a vibration arrangement (2) for vibrating the container (4). The vibration arrangement (2) comprises a frequency generator (21) adapted to provide an electrical signal and a transducer (22) adapted to transduce the electrical signal provided by the frequency generator (21) into an acoustic wave (221). The seat (6) is adapted to position the container (4) adjacent to the transducer (22). for inspecting a liquid inside a container (4) with respect to the existence of particles (5). The inspection device (1) allows for an accurate and gentle inspection of the liquid filled in the container and for detecting particles in the liquid.
