摘要：A process for preparing two connected powder transfer conduits for cleaningwithout releasing powder from the conduits. The conduits are connected to each otherby flexible tube of a water-dissolvable material to enable powder communicationbetween the two conduits. A sealing operation is performed to form a seal in the tubesufficient to prevent the powder communication from one side of the seal to the other.The seal is then severed to produce two tube sections where each tube section is sealedat the point of severance. A cleaning conduit is then place over at least one of the twotube sections and connected to the respective conduit. The cleaning conduit is connectedto a liquid cleaning source which is adapted to deliver a cleaning liquid capable ofdissolving the tube section thereunder upon contact therewith.
