To maintain fermentation quality in pig manure organic fertilizer production lines, focus on these key aspects:

1. Raw Material Preparation

The pretreatment of pig manure organic fertilizer production line is the basis. After collecting pig manure, remove impurities like stones or plastic that could hinder fermentation. Adjust moisture content to 50-60% - too wet causes poor aeration, while too dry limits microbial activity.

2. Microbial Management

Select effective microbial strains like Bacillus and yeast. These microbes efficiently break down organic matter into plant-available nutrients while forming a stable community. They accelerate decomposition and naturally suppress harmful pathogens through competitive growth.

3.Process Control

During the fermentation process, it is crucial to accurately control the fermentation conditions. In terms of temperature, it should be maintained between 50℃ - 65℃, which is the temperature range where most beneficial microorganisms are active. Through the automated temperature control system, such as the coordinated work of heating equipment and ventilation equipment, the temperature stability is ensured. In addition, ventilation should not be ignored. The appropriate ventilation volume can ensure the supply of oxygen, promote the growth of aerobic microorganisms, and discharge waste gases such as carbon dioxide.

4. Fermentation Duration

The fermentation time needs to be determined based on factors such as the amount of pig manure and the activity of microorganisms. Generally speaking, the complete fermentation cycle needs to last 15-30 days. Sufficient fermentation time can ensure that the pig manure is fully decomposed, make the nutrients of organic fertilizer more stable, and reduce the adverse effects of undecomposed substances on crops, thereby ensuring that the pig manure organic fertilizer production line produces high-quality organic fertilizer.
