To improve the granulation technology of organic fertilizer production lines to reduce caking, the following measures can be taken:

1. Control the production time: Avoid production in the rainy season and high temperature season, and choose production in spring, late autumn and winter to reduce the probability of caking.

2. Add anti-caking agent: add talc powder, humic acid and other powder in the production process, or use surfactants to reduce the adhesion between particles.

3. Improve the packaging method: adopt a reasonable packaging method to prevent extrusion, choose packaging materials that can prevent moisture absorption and breathability, and avoid excessive extrusion.

4. Improve granulation technology: The use of disc granulator or double roller press granulator, these devices can produce uniform particles, dry organic fertilizer, reduce caking. adjustable

5. Whole granulation parameters: During the granulation process, adjust the distance of the extrusion roll to maintain the required extrusion pressure and ensure the uniformity and dryness of the particles.

6. Improve the quality of granulation: Improve the quality and stability of granulation by improving the granulation process, such as the use of closed reflux cycle treatment technology.

7. Use of new equipment: Consider the use of new organic fertilizer equipment, such as disc extrusion granulation technology, which can improve the efficiency and quality of granulation.

8. Regular maintenance of equipment: Ensure that the granulation equipment is in good condition, regular cleaning and maintenance to prevent caking caused by equipment problems.

Through the above measures, the caking phenomenon in the organic fertilizer production line can be effectively reduced, and the product quality and production efficiency can be improved.
