To ensure product quality in an organic fertilizer produciton line, consider the following aspects:

1. Raw Material Control: Organic fertilizer raw materials come in a wide variety of types. Pre-production requires rigorous screening to remove impurities to prevent damage to equipment and impair granulation. Raw material moisture content is a key factor. Suitable organic fertilizer raw materials for granulation should have a moisture content between 20% and 30%. Excessively high or low moisture content can affect the granulation process. Adjust the moisture content by drying, airing, or adding dry materials.

2. Equipment Maintenance: Select an appropriate granulator based on the raw material characteristics. For example, a disc granualtor is suitable for sticky materials, while an extruder granulator is suitable for fibrous materials. Maintain and lubricate your organic fertilizer equipment regularly to reduce wear and extend its service life. Regularly inspect the equipment and replace wearing parts promptly to prevent malfunctions. Additionally, have professional personnel perform regular maintenance to ensure proper operation.

3. Process Optimization: Control the feed rate and adjust it according to equipment performance to avoid excessively high or low feed rates that may affect granulation. Adjust equipment parameters such as speed, pressure, and temperature based on raw material characteristics to ensure optimal granulation results. 4. Personnel Training: Improve employee proficiency in production processes and equipment operation, ensuring that every step is carried out in strict accordance with standards. Furthermore, cultivate employees' quality awareness, enabling them to promptly identify and resolve production process problems.

Through these measures, we can effectively ensure product quality in the organic fertilizer production line, improve production efficiency, and enhance product market competitiveness.
