Improving the corrosion resistance of organic fertilizer equipment is the key to ensuring the long-term stable operation of the equipment and reducing maintenance costs. The following are some specific methods and measures:

1. Select corrosion-resistant materials: Choose high-quality stainless steel. For some components with high-strength requirements, corrosion-resistant alloy materials can be used, which can maintain good performance even in extreme environments.

2. Surface anti-corrosion treatment: Spray high-performance anti-corrosion paint on the surface of the equipment to form a protective film. These coatings can effectively resist the corrosion of media such as organic acids and sulfides.

3. Regular maintenance and inspection: Regularly inspect the corrosion condition of the equipment, especially the welds, tank walls and other easily corroded areas, and promptly identify and address any corrosion issues. If any damage to the anti-corrosion coating is found, it should be repaired in time to prevent the corrosion from spreading further.

4. Environmental control: Keep the surrounding environment of the equipment dry to reduce the corrosive impact of damp conditions on the equipment. Ensure that the operating environment of the equipment is well-ventilated to reduce the accumulation of harmful gases.

5. Process optimization: Before the materials enter the equipment, control their moisture content to prevent high-humidity materials from causing corrosion to the equipment. During the fermentation process, an appropriate amount of buffer (such as wood ash) should be added to adjust the pH value of the materials and reduce the corrosion of the equipment by the acidic environment.

Through the above measures, the corrosion resistance of organic fertilizer equipment can be effectively enhanced, the service life of the equipment can be prolonged, the maintenance cost of the organic fertilizer production line can be reduced, and the long-term stable operation of the equipment can be ensured.
