Filed:

Feb 7, 1977

Appl. No.:

5/766132

Inventors:

Donald F. Link - Huntsville AL

Assignee:

Recovery Systems, Inc. - Charleston SC

International Classification:

B02C 1316

US Classification:

241 46R

Abstract:

A system for pulverizing waste food and converting it into dried animal feed in which the waste food is first passed through a cylindrical chopper comprising a pivotally mounted hammer on a rotating plate which operates in relationship to a fixed cylindrical surface of lands and grooves, and thereafter, the food is passed between horizontally arranged and relatively rotating sets of lands and grooves. The material is then passed to a buffer storage tank where it is agitated to maintain consistency, and thereafter, in a constant flow provided to a rotating drum-type dryer where the material is dried and formed into flakes having a moisture content of 10 to 14 percent.
