A silo or cylindrical composting apparatus containing more than one chamber, each of which is fitted with two or more sets of agitator arm assemblies, a system of sweep paddles, and a shielded exit port with a slidable panel cover. The agitator arm assemblies are supported at the common central shaft and at the circumference of the chamber. The central shaft revolves and likewise causes the agitator arm assemblies and sweep paddles to revolve with it. A unique ring gear track about the circumference of the chamber articulates with a gear of each agitator arm assembly and causes the arm assemblies to rotate as they revolve. Air is supplied to the composting mass through the central shaft and into the air delivery pipes which are a part of each agitator arm assembly. A heat collecting system removes excess heat from the upper chambers and makes it available for use in the lowermost chamber if needed. The central shaft is made to revolve by means of a drive wheel powered by a motor located outside the silo. Fan blowers also located outside the silo bring in fresh air.
