According to the search results, the following are the energy-saving and power-saving methods for organic fertilizer production lines:

1. Optimize equipment and processes: Adopt energy-saving organic fertilizer equipment such as variable frequency speed regulation crushers and extrusion granulators, which can flexibly adjust the rotational speed according to the material characteristics and production requirements, avoiding energy waste.

2. Energy Management and Monitoring: Set clear energy management goals and plans, and conduct statistics, analysis and management of energy consumption on production lines. By collecting the energy consumption data of each device in real time through sensors, refined management of energy consumption is achieved, effectively reducing energy consumption.

3. Waste heat recovery and recycling: In the drying process, heat exchangers are used to recover the waste heat from the drying tail gas, which is then used to preheat the materials or heat the air, thereby enhancing the energy utilization rate of the drying process.

4. Adopt renewable energy: Where conditions permit, enterprises may consider using renewable energy sources such as solar and wind power to provide part of the energy for organic fertilizer production lines, reducing reliance on traditional energy sources and lowering energy procurement costs.

5. Optimize raw material formula and pretreatment: Through scientific testing and analysis, optimize the raw material formula to bring the carbon-nitrogen ratio to the ideal range, promote efficient microbial fermentation, and reduce energy consumption. Ensure that the moisture content of the materials entering the crusher is moderate to avoid an increase in equipment load due to excessive moisture, which could lead to excessive heat generation.

By implementing these energy-saving measures, organic fertilizer producers can significantly reduce energy consumption, lower operating costs and enhance market competitiveness while ensuring production quality.
