<p>An organic digesting system (10) incorporating a pair of digester units (12, 14) each of which includes an elongated, horizontally disposed frusto-conical, stationary outer drum (18, 68) including a correspondingly frusto-conical inner drum (28, 78) that is rotatably driven about a horizontal axis. Each of the inner conical drums (28, 78) is contracted of foraminous material to form a periphery (30) that is porous with the foraminous periphery of the inner drum (28, 78) being supported from support shafts (40, 50) at each end thereof. The interior of the inner drum (28, 78) is provided with a plurality of inwardly extending agitation blades (64) which arse spaced peripherally on the interior of the inner drum (28, 78) and arranged in longitudinally spaced arrays. Also, each inner drum (28, 78) is provided with a plurality of outwardly extending oute r agitation blades (62) with the function of these blades being to min, agitate and chum the organic material while lifting and moving it fr om the entrance to the upper outer drum (18) to the discharge into the lower outer drum (68) and to the discharge outlet from the lower outer drum (68).</p> |
