ABSTRACT:
An aeration drum is rotatably-mounted for rotation about a longitudinal axis oriented horizontally inside a housing which has an air inlet and air outlet for venting the unit. A removable receptacle receives decomposed solid waste matter from the aeration drum for periodic removal from the unit. The aeration drum has a narrow end, and a wide end extending radially outwardly from the narrow end. In a preferred construction of the aeration drum, the narrow end has a constant diameter over a short length of the drum and the wide end has a constant diameter over a greater length of the drum. A perforated collar on an intermediate portion of the drum between the narrow end and the wide end allows liquid to drain from the narrow end into the wide end while retaining the solid waste in the narrow end where it decomposes. The wide end has a liquid discharge in fluid communication with the housing and the narrow end has a solid waste discharge for radial discharge into the receptacle. The configuration of the drum defines a bottom surface at the wide end which is always lower than at the narrow end of the drum thereby improving the separation of liquid waste from solid waste.
