  • Apparatus for the hydraulic conveyance of substances and use thereof
    Patent number: 4863377
    Abstract: A conveyance channel (76) connects an inlet valve (74) to a free outlet (82) whereby the conveyance channel (76) first passes through a sterilization zone (78) and then through a cooling zone (80). Within the cooling zone (80), the conveyance conduit contains resistor areas (94, 96). This makes it possible to reduce the conveyance pressure in the conveyance channel (76) against the outlet (82) to such an extent that packings sterilized in the conveyance channel (76) are able to exit the outlet (82) virtually pressureless.
