Key factors in organic fertilizer production line fermentation: A simple guide
In organic fertilizer production lines, fermentation is a critical step. Its success depends on several factors:
- Raw Material Properties
The raw material’s composition directly affects fermentation. For example, the carbon-to-nitrogen (C/N) ratio should stay between 25:1 and 35:1. A high C/N ratio slows microbial growth, extending fermentation time. A low ratio may cause ammonia loss, reducing nutrient content.
Moisture is also vital. Aim for 50%–60% moisture—too wet limits airflow, while too dry starves microbes.
- Microbial Activity
The right mix of bacteria, fungi, and actinomycetes drives efficient fermentation. Adding high-quality microbial agents speeds up the process. These microbes break down organic matter into nutrient-rich humus.
- Temperature Management
Start with a warm-up phase (20–45°C) for moderate-temperature microbes.Then, let temperatures rise to 45–65°C. This “high heat” phase kills pathogens and weeds.Avoid extreme temperatures—they disrupt microbial activity.
- Oxygen Supply
Good airflow keeps aerobic microbes active. Use compost turning machines or ventilation channels to maintain oxygen levels. Poor airflow risks anaerobic conditions, leading to bad odors and failed batches.
- Equipment Design
Automated systems improve quality and efficiency. Sensors monitor temperature, moisture, and oxygen levels, adjusting ventilation or mixing speed as needed.
In short, during the fermentation process of the organic fertilizer production line, we must always pay attention to whether the various fermentation parameters (temperature, humidity, ventilation, etc.) are normal to ensure the smooth progress of the fermentation process and ensure the final fermentation quality of the organic fertilizer.
