Abstract (en)

[origin: WO9722765A1] An air floor for curing compost made of a series of light weight, relatively short grates (10) each containing a plurality of air slits (12) narrow at the top (14) of the grate openings and progressively widening toward the bottom (16) of the opening and structure (20) supporting the grates (10) to provide a span spaced to limit the bending moment to which the grates (10) are subjected and to provide space (26) beneath the grates (10) to facilitate removal of compost passing through the air slits (12) and to permit unobstructed air flow through the grates (10).
