NOVELTY - Kitchen waste disposal system comprises: a residue feeding mechanism which receives kitchen waste and leads the kitchen waste into a mechanical gear grinding zone in the disposal system; a mechanical gear grinding mechanism (3) with a double-shaft bi-directional gear grinding component; and a paddle-type stirring mechanism (6) comprising a W-shaped treatment groove and a paddle component in the middle of the treatment groove. Two gear shafts are arranged in parallel and rotate in opposite directions, where each gear shaft is provided with first buckle gears and second buckle gears.    USE - The kitchen waste disposal system is useful to prepare granular organic fertilizer (claimed). No biological data given.    ADVANTAGE - The kitchen waste disposal system: can convert kitchen waste into organic fertilizer in hours, thus effectively improving soil structure, facilitating the growth of crops, achieving hygienization and harmless treatment of waste, and contributing to the recycling of resources, where the prepared granular organic fertilizer can be shoveled to the fertilizer outlet more easily; releases clean water which is harmless to the environment; avoids pollution of air and environment and disturbance by mosquitoes and flies; utilizes large temperature control scope, which provides excellent heat certainty, rapidity in heating and cooling and accurate temperature control and computerized touch control, and thus the double-electric temperature control tube can maintain a constant temperature environment in the treatment groove; utilizes four-corner balance electronic scale which can be used to conveniently record weight data during feeding and discharging; directly converts the organic waste into high quality organic fertilizer products, so that pollution sources are greatly reduced, energy losses caused by transporting and disposal can be carried out in the conventional manner, cut down on the labor cost, achieving high resource recycling efficiency, and providing harmless soil and healthy air; reduces the volume and weight of the kitchen waste by over 90% without heating, during which the deodorization system can filter air odor, thus effectively optimizing the working environment; and disposes waste on the spot, so that resources for piling up to be treated and transporting are saved.    DETAILED DESCRIPTION - Kitchen waste disposal system comprises: a residue feeding mechanism which receives kitchen waste and leads the kitchen waste into a mechanical gear grinding zone in the disposal system; a mechanical gear grinding mechanism (3) with a double-shaft bi-directional gear grinding component; and a paddle-type stirring mechanism (6) comprising a W-shaped treatment groove and a paddle component in the middle of the treatment groove. Two gear shafts are arranged in parallel and rotate in opposite directions, where each gear shaft is provided with first buckle gears and second buckle gears, and the first buckle gears and the second buckle gears are combined to crush the kitchen waste from the residue feeding mechanism. The kitchen waste is crushed into paste by the mechanical gear grinding mechanism, where the pasty kitchen waste is stirred in the treatment groove and then treated with water evaporation, circulated temperature baking and ventilative deodorization to prepare granular organic fertilizer which is shoveled by the paddle component to the outlet.
