Patent ID: 8292085

Claim:
A solids separation system comprising: (a) a barrel, said barrel formed as a hollow frustum of a cylinder and having a low density solids exit end, a high density solids exit end, and a barrel wall forming an interior barrel surface and an exterior barrel surface; (b) at least one blade helically wound along said interior barrel surface of said barrel with at least one turn around the circumference of said barrel approximately from said high density solids exit end to substantially said low density solids exit end, and said blade having height, width and length; (c) barriers affixed to said interior barrel surface, said barriers mounted in a substantially perpendicular orientation between the turns of said helically wound blade; (d) a carriage on which said barrel is arranged in a substantially horizontal arrangement and further rotatably arranged and inclined so as to elevate said low density solids exit end of said barrel in relation to said high density solids exit end; (e) a blower placed at said high density solids exit end of said barrel and arranged to force air through said barrel roughly parallel to said barrel wall; (f) a blower motor arranged to power said blower; (g) means for rotating said barrel; and (h) means for delivering a mixture into said barrel so that said mixture passes through said forced air.
