ABSTRACT:
A composter including a fermentation compartment located on top of a compost drying compartment. A shutter is located between the compartments to control the transfer of composted material into the drying compartment. In an alternative composter the drying compartment tank is horizontally adjacent the fermentation compartment. A stirring screw is located in the fermenting compartment. During the fermenting process, the stirring screw is rotated back and forth so as to continually mix the material being composted. Once the composting process is completed, the stirring screw is rotated in one direction to transfer the composted material through openings in a separation wall and into the drying compartment.
