High-quality organic fertilizer starts with high-quality raw materials. Establishing strict raw material acceptance criteria is essential:
Material Type |
Moisture Requirement |
Impurity Limit |
Pretreatment Method |
Livestock Manure |
<60% |
<5% |
Solid-liquid separation, deodorization |
Crop Straw |
<15% |
<3% |
Crushing to 3-5cm |
Food Waste |
<85% |
<1% |
Oil separation, sterilization |
Fermentation is the core process of organic fertilizer production line. Research shows that maintaining the following parameters can improve fermentation efficiency by over 30%:
· Temperature: 55-65℃ (maintain high-temperature period for 7-10 days)
· Moisture: 50-60%
· C/N Ratio: 25-30:1
· pH Value: 6.5-8.0
Investing in automated equipment can significantly improve production line stability:
· Automatic batching system: error <1%
· Intelligent compost turner: saves 50% labor
· Online monitoring system: real-time process parameter adjustment
· Packaging robots: precision up to ±0.1kg
Establish a comprehensive quality inspection system from raw materials to finished products, including:
· Raw material incoming inspection
· Fermentation process sampling
· Finished product physical and chemical index testing
· Heavy metal and pathogen screening
Regularly conduct:
· Equipment maintenance
· Process parameter optimization
· Operator skills training
· New technology evaluation
Through the systematic implementation of these five strategies, organic fertilizer producers can not only achieve efficient and stable operation of production lines but also continuously produce high-quality organic fertilizers that meet international standards, satisfying the growing demand of global organic agriculture.
