ABSTRACT:
A rotary composter having a rotatably mounted cylindrical vessel is divided into a plurality of compartments, including a first infeed compartment, a last discharge compartment, and a plurality of intermediate digesting compartments, by baffles. The baffles between each of the infeed and discharge compartments and the adjacent digesting compartments are provided with weirs to retain a supply of microbial inoculant material. The drive mechanism operably powering the rotation of the vessel is variable in speed to permit the rotational speed of the vessel to be selectively varied. Air is forced through the vessel by a variable speed fan for selectively changing the rate of air flow through the vessel from the discharge end to the infeed end.
