NOVELTY - Method for continuous production of solid and liquid organic fertilizer using livestock and poultry excrement, involves (i) adding livestock and poultry excrement to solid-liquid separation unit, performing solid-state fermentation, and conveying fermented product to drying unit to obtain solid products, or (ii) adding the livestock and poultry excrement to solid-liquid separation unit, and then adding obtained product to liquid fermentation unit to obtain liquid products.    USE - The method is useful for continuous production of solid and liquid organic fertilizer using livestock and poultry excrement (claimed), where the organic fertilizer is used for crops.    ADVANTAGE - The method is environmentally-friendly as it causes no pollution, and performed cost-effectively, consumes less time, meets requirements of organic fertilizer for crops, and enables large-scale processing of livestock and poultry excrements.    DETAILED DESCRIPTION - Method for continuous production of solid and liquid organic fertilizer using livestock and poultry excrement, involves (a) setting solid-liquid separation unit for livestock and poultry excrement, solid-state fermentation unit, drying unit and liquid fermentation unit, and (b) (i) adding the livestock and poultry excrement to solid-liquid separation unit, performing solid-state fermentation, and conveying fermented product to drying unit to obtain solid products, or (ii) adding the livestock and poultry excrement to solid-liquid separation unit, and then adding obtained product to liquid fermentation unit to obtain liquid products. The solid-liquid separation unit, solid-state fermentation unit and drying unit are connected in series. A feeding device equipped with screw press is provided for continuously feeding the livestock and poultry excrement. The livestock and poultry excrement is continuously extruded by the screw press. The solid product is separated, stirred and then subjected to solid-state fermentation using microbial agents. The stirring process is performed using stirrer equipped with stirring drive which drives shaft of stirrer. The fermented product is dried and smothered. The feeding rate of the livestock and poultry excrement, and fermentation temperature are controlled using computer. The solid product is continuously subjected to biochemical treatment. The method involves mixing biochemically treated product with microelements, uniformly stirring obtained mixture, drying the mixture by hot air circulation in a drying room, controlling drying temperature using computer, and packing obtained solid fertilizer products.
