<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 contructed 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 are 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 outer agitation blades (62) with the function of these blades being to mix, agitate and churn the organic material while lifting and moving it from 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> |
