    • Said installation comprises a liquid circulation pipe (13), having an upstream portion (21), a downstream portion (23) and a filtering member (37), inserted between the upstream portion (21) and the downstream portion (23), at least one channel (51) being provided in said filtering member. The channel (51) is at least partially defined by a porous wall (57). Said pipe (13) comprises a double vacuum thermal insulation envelope (14), containing an insulating material, in a part of which the filtering member (37) is secured. One of said portions (21) opens out facing an end of said channel (51). The other of said portions (23) opens out facing at least one area (59) of the porous wall (57). Said invention applies to the production of high flow rate sterile cryogenic fluids.
    • 所述装置包括:液体循环管(13),其具有插入上游部分(21)和下游部分(23)之间的上游部分(21),下游部分(23)和过滤部件(37) 至少一个通道(51)设置在所述过滤构件中。 通道(51)至少部分地由多孔壁(57)限定。 所述管道(13)包括一个包含绝缘材料的双重真空绝热外壳(14),其中一部分过滤构件(37)被固定。 所述部分(21)中的一个朝向所述通道(51)的端部开口。 所述部分(23)中的另一个朝向多孔壁(57)的至少一个区域(59)开口。 本发明适用于生产高流量无菌低温流体。
