How to ensure good ventilation during the fermentation process of pig manure organic fertilizer production line?

During the fermentation process of the pig manure organic fertilizer production line, ensuring good ventilation can be achieved from the following aspects:

Equipment Selection  

1. Compost Turning Machine: Use a high-quality turner to flip and mix materials over 1.5-3 meters. Fast turning speed and thorough mixing boost air exposure.  

2. Ventilation Fans: Choose fans based on needs. Use dust-removal fans for dusty airflows and standard fans for clean air. Match fan types to required airflow and pressure.

Air Duct Layout  

Distribute air ducts evenly to prevent dead zones. A grid-style layout works well for horizontal and vertical airflow spread, while layered setups suit deeper fermentation tanks by placing outlets at different levels.  

Condition Control  

1. Temperature control: The fermentation temperature is controlled at 55-70℃, which is the suitable temperature range for microbial growth. It can effectively kill pathogens and parasites, and accelerate the decomposition of organic matter. It can be adjusted by installing temperature sensors and using heating or ventilation equipment.

2. Humidity control: Keep the humidity of the fermentation environment within a certain range to avoid the material being too dry or wet, which will affect the growth and fermentation effect of microorganisms.

3. pH value control: The pH range for the growth of microorganisms is 6.5-8.5, which can be adjusted by adding regulators such as lime and gypsum.  

Process Management  

1. Regular Turning: Flip materials 1-2 times daily using turners to mix thoroughly and enhance air contact.  

2. Monitoring: Use sensors to track temperature, humidity, and oxygen levels. Adjust settings as needed for stable airflow.

In short, during the fermentation process of the pig manure organic fertilizer production line, by paying attention to ventilation equipment, pipeline layout, condition control, and material turning, good ventilation effects can be guaranteed, thereby improving the fermentation quality of organic fertilizer.
