Optimization and Experiment of Livestock and Poultry Manure Composting Equipment with Vented Heating

As livestock and poultry farming expands in China, the generation of fecal waste has significantly increased. Inadequate management can contribute to environmental pollution. This study seeks optimize small-scale composting systems address inefficiencies limited automation traditional equipment. We redesigned mixing blades refined ventilation heating system, establishing an efficient mechanism energy-saving system. A control incorporating Monitor Control Generated System Programmable logic Controller, was developed for real-time monitoring adjustment capabilities, substantially enhancing levels. The optimization proved effective by reducing cycle from 13 days 11.5 days, increasing GI value 83% 89%, lowering humidity 8.9% 8.1%.
