Abstract
In a hydro-extractor, a screw is disposed with an outer concentric cylindrical sieve. The sieve is formed of sections placed lengthwise of the screw, with each section capable of having the same or different size holes so that the extractor captures solids both large and small in a controlled manner and will dewater faster or slower with various combinations of sieve sections. To increase solids capture in desired portions of the extractor, the sieve is formed with a cloth or other fibrous material disposed between two supporting members.
