DETAILED DESCRIPTION - A kitchen waste composting device comprises box body (6) and base (7). The box body has a cover (1) with adjustable upper ventilation holes (8), and a filter screen (2) on the bottom. The base is provided with ventilation shutters (3), and a liquid and residue collecting device (4). The filter screen is disposed between box body and base, and located above the liquid and residue collecting device. The filter screen uses a wooden or metal mesh for kitchen waste and supporting ventilation. The liquid and residue collecting device is a drawer-type extraction device comprising front and back sides, a drawer handle (9) provided on front side, and a lower water outlet. The ventilation shutters are arranged on left and right sides of the base relative to the liquid and residue collecting device. When the ventilation shutters open, air enters into the box body. The composting device further includes a garbage bag provided with small holes from the bottom up to 1/3 of its height. Air is transmitted into the box body through filter screen and small holes of garbage bag, while excess wastewater flows through the small holes and filter screen into the liquid and residue collecting device.
