US Patent 10525483 Dissolved air flotation skimmings separation system and method

A DAF skimmings separation system 10 that processes SPN/DAF skimmings 11 received from a meat processing facility to separate water and SPN-content solids includes a heating chamber coupled to a processor chamber having one or more pressurized discharge nozzles that expels DAF skimmings onto a spatter plate to cause SPN animal components within the DAF skimmings to break into smaller pieces denaturing the molecular structure and allowing the entrapped moisture to be evaporated within a heated airstream in the processing chamber, for separating nutritionally valuable SPN while reducing moisture content. A method of processing DAF skimmings to yield dryer SPN with reduced moisture content is disclosed.
