Abstract:
1. A process of treating organic waste for anaerobic digestion of biogenic-organic substances, comprising the following process steps: a. preparing a waste-slurry from said organic waste; b. transferring said waste-slurry to a paddle pulper/finisher c. forming a finisher-slurry in said paddle pulper/finisher and separating a pulp and a pomace from said finisher-slurry in said paddle pulper/finisher, said paddle pulper/finisher having a cylindrical screen body formed with small discreetly spaced openings throughout said body between inlet and outlet end openings; at least one elongated paddle extending a substantial portion of the length of said cylindrical screen body carried on a rotating paddle shaft having an axis concentric with the longitudinal axis of said cylindrical screen, and said paddle being formed with a paddle edge positioned in close proximity to said cylindrical screen body; said paddle having a pitch for propelling said finisher-slurry toward said outlet opening while pressuring said finisher-slurry radially outwardly and against said cylindrical screen body thereby reducing the particle size of said finisher-slurry by action of said paddle, extruding and forming said pulp exiting through said screen openings, and said pomace exiting said cylindrical screen body through said outlet opening; transferring said pulp to an anaerobic digester; and digesting said pulp in said anaerobic digester.
