ABSTRACT:
This invention relates to an improvement in a press for dehydrating material in which the material is passed between two endless sieve belts adapted to move in the same direction and to pass over and around pairs of rollers and/or offset upper and lower rollers, the rollers in various sets forming a pre-dehydration zone and a wedging or compression zone,
The improvement comprising a compression zone in the form of a frame-like structure, said structure containing individual compression roller means mounted on bearing blocks of varying heights,
And means for displacing and/or exchanging said bearing blocks, whereby a path for said material has an ascending slope with line compression, or is wavelike or S-shaped with surface compression.
