Abstract
The study on design criteria of solid-liquid separator for dairy farms was done by testing various screens, presses, and RPMs of screw auger with remodeled screw-press type pig-manure separator. The moisture content of separated solid increase from 68.3% to 74.2% as auger rotating speed increased from 9.8 to 29.2 RPM at 34.8 kPa of pressure and 1.0 mm of slit wedge wire screen condition. The moisture contents of separated solid were 72~77%, work efficiencies were 16~18 kg/min at 1.0 mm of slit wedge wire screen. The efficiency was higher than one at 0.5 mm of slit wedge wire screen, which was used to separate for pig manure. The best work efficiency was 18 kg/min at 42.5 kPa, 1.0 mm slit screen. The separated solid moisture content was 75% at this condition.
