Abstract
The press installation includes a screw rotatably mounted in a cylinder. A very high pressure is produced to separate liquids from a mixture, with the separated liquid being drained off through bore holes in stationary pins at the location where it is released. In the discharge zone, the screw is devoid of threads whereby the annular cross sectional area between the screw core and the cylinder is increased. This extends the retention time and thus the amount of dehydration of the material as it passes through the discharge zone. Additionally provided in the discharge zone are annular offsets around the screw core in the vicinity of the pins, which prevent the penetration of solids into the drainage bore holes.
