McLanahan has recently introduced roll press technology to its line of rotary liquid-solid separation equipment. The roll press will complement the operation of rotary separators by offering dairy producers an alternative to screw press technology for dewatering manure solids.
Separated solids from rotary screens are fed into the roll press at about 10 percent TS (total solids). The solids are then pressed to remove excess water to produce a stackable, compostable product.
A single stage press produces a stackable product at about 16 percent TS. A double stage press produces solids in the range of 22 to 28 percent TS, which can be stockpiled with no leachate. A triple stage press further decreases the moisture to about 25 to 32 percent TS.

The presses are manufactured of stainless steel and built to provide years of reliable operation. PD
