<p>A closed system for reclaiming ink, solvent, and water from waste lithographic ink, or other ink types, without generating hazardous by-products, wherein a recycling process is performed under vacuum conditions using standard equipment, such as an agitation station (12), an evaporator (18), a grinder (20), a condensation tank (16), and a vapor exhaust recovery condenser (18), all of which are readily available in the ink industry. Waste ink containing ink solids, solvent, water, and possibly foreign material such as debris, lint, paper, and dust, is first mixed to create a homogeneous slurry mixture. Next, water and solvent are evaporated from the slurry mixture and collected. The slurry mixture is ground, which generates heat to evaporate any remaining water and solvent from the slurry.</p> |
