In the production process of organic fertilizer production lines, it is very important to avoid cross-contamination to ensure product quality and environmental safety. Here are some key measures:

1. Distinguish raw material storage areas: Set separate storage areas for different types of raw materials to avoid mixing and cross-contamination between raw materials.

2. Cleaning and disinfection: Thoroughly clean and disinfect equipment and tools before producing different batches or different types of organic fertilizers.

3. Use special organic fertilizer equipment: use special production lines and equipment as much as possible, or thoroughly clean the equipment when replacing raw materials.

4. Strict operating procedures: Develop strict operating procedures to ensure that operators follow correct cleaning and disinfection procedures when handling different raw materials.

5. Material management: Ensure the closure of materials during handling, transportation and storage to prevent pollution from foreign substances.

6. Regular testing: Regular microbial testing of the production line, equipment and products to ensure that there is no harmful microbial pollution.

7. Staff training: Conduct cross-contamination prevention and control training for employees to improve their health awareness and operational skills.

8. Physical isolation: physical isolation measures are set up on the production line, such as partitions or independent rooms, to isolate the processing of different raw materials.

9. Product traceability: Establish a product traceability system to quickly locate and deal with pollution problems once they occur.

Through the implementation of these measures, we can effectively control and avoid the cross contamination in the organic fertilizer production line to ensure the quality and safety of products.
