摘要: In this work, we engineered a pilot scale process for the production of granulated organic- and organo-mineral fertilizers (OGF OMF) from poultry manure. We investigated effects moisture content in manure, energy consumption during three main stages possibility to obtain nutrient balanced using conventional straw drying granulation equipment, common on farms. Poultry manure was dried shredded no less than 90% dry mass at 95 °C. Granulation performed via extrusion with without mineral additives, such as diammonium phosphate (DAP) potassium chloride (KCl). This used achieve 4-3-3 OGF, well tunable NPK (4-4-2, 4-3-6 4-4-9) OMF. Energy about 100 kWh/t product. limiting step suggests that maximum achievable sub 10% water currently commonly is not necessarily economically optimal. DAP increase water-soluble ...
