Abstract
A worm compost system has a plurality of pairs of working trays, each working tray including an upwardly extending sidewall extending from a base to an upper perimeter to form an internal chamber. A lid assembly is positioned on a topmost pair of the working trays, and a harvest tray is removably attachable beneath a bottommost pair of the working trays, the harvest tray configured to collect processed compostable material. A movement mechanism including a set of bearings is disposed between nested trays of each pair of working trays, the bearings enabling relative rotational movement of the trays to facilitate passage of compostable material downward through the system.
Claims15
A worm compost system comprising:
- a plurality of pairs of working trays, each working tray including an upwardly extending sidewall extending from a base to an upper perimeter to form an internal chamber;
- a lid assembly positioned on a topmost pair of the working trays;
- a harvest tray removably attachable beneath a bottommost pair of the working trays, the harvest tray configured to collect processed compostable material;
- and
- a movement mechanism including a set of bearings disposed between nested trays of each pair of working trays, the bearings enabling relative rotational movement of the trays to facilitate passage of compostable material downward through the system.
A worm compost system comprising:
- a plurality of stacked tray assemblies, each tray assembly including an inner tray and an outer tray, the inner tray being rotatable relative to the outer tray about a generally vertical axis;
- each tray having a perforated or lattice base such that relative rotation changes alignment of openings to control passage of compostable material;
- a low-friction rotational interface disposed between the trays, the interface including bearings, rollers, bushings, or equivalent structures;
- a lid covering an uppermost tray assembly;
- and
- a harvest receptacle positioned below a lowermost tray assembly to collect castings and leachate.
