Abstract
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.
Claims27
A DAF skimmings separator system for separating SPN animal component solids from water within a supply of DAF skimmings, comprising:
- an exhaust fan for creating an airstream;
- a heating chamber having a heat source to heat the airstream;
- a processor chamber in fluid communication with said heating chamber, said processor chamber having an animal component solids outlet and an airstream outlet;
- a liquid pressurizing pump coupled to a DAF skimmings input conduit terminating at an introductory pressure nozzle positioned within said processor chamber, said liquid pressuring pump being adapted to pressurize a supply of DAF skimmings expelled through said introductory pressure nozzle;
- a spatter surface positioned within said processor chamber adjacent to and aligned with said introductory pressure nozzle so that the pressurized DAF skimmings ejected from said introductory pressure nozzle impacts upon said spatter surface with sufficient force to cause animal components within the DAF skimmings to break into smaller pieces;
- a first animal component solids collector in fluid communication with said processor chamber animal component solids outlet;
- a separator in fluid communication with said processor chamber airstream outlet to separate animal component solids from the airstream passing through said separator, said separator having an air outlet and an animal component material outlet, and
- a second animal component solids collector in fluid communication with said animal components material outlet.
A DAF skimmings separator system for separating animal component solids from water within a supply of DAF skimmings, the DAF skimmings separator system comprising:
- a heated airflow creating system including a heater, an exhaust fan, and a processor chamber for separating animal component solids from an airstream carrying the animal component solids;
- a liquid pressurizing system having an introductory pressure nozzle positioned within said processor chamber for pressuring and ejecting a supply of DAF skimmings containing animal components and water;
- a spatter surface positioned within said processor chamber adjacent said introductory pressure nozzle so that the pressurized DAF skimmings ejected from said introductory pressure nozzle impacts upon said spatter surface with sufficient force to cause animal components within the DAF skimmings to break into smaller pieces, and
- an animal component solids collector in fluid communication with said processor chamber.
A method of separating animal component solids from water within a supply of DAF skimmings, the method comprising the steps of:
- (a) providing a DAF skimmings separator system having a heated airflow creating system, a processor chamber, a liquid pressurizing system having an introductory pressure nozzle positioned within the processor chamber for pressuring and ejecting a supply of DAF skimmings containing animal components and water, and a spatter surface positioned within the processor chamber adjacent the introductory pressure nozzle;
- (b) pressurizing a supply of DAF skimmings containing animal components and water;
- (c) ejecting the supply of DAF skimmings through the introductory pressure nozzle so as to impact upon the spatter surface positioned within the processor chamber with a force sufficient to break the animal components within the DAF skimmings into smaller pieces;
- (d) entraining a portion of the animal components impacted upon the spatter surface into an airstream created by the heated airflow creating system;
- (e) conveying the airstream containing a first portion of the animal components from the processor chamber, and
- (f) collecting a second portion of the animal components within the processor chamber which were not entrained into the airstream.
