The operation process of the cow manure organic fertilizer production line involves a series of steps from collecting cow manure to packaging the finished fertilizer, with the aim of converting agricultural by-products into high-quality organic fertilizers. The following is a detailed overview of the process:

1. Raw material collection and pretreatment

Collect cow manure: Regularly collect fresh or partially fermented cow manure from the cowshed.

Remove debris: Use a screening machine or manually remove possible foreign objects, such as plastic, stones, and other non organic substances.

2. Fermentation and maturation

Composting: Storing cow manure in a dedicated area for natural or temperature controlled fermentation, during which the pile needs to be turned over to increase oxygen supply, promote microbial activity, and accelerate organic matter decomposition.

3. Drying

After fermentation, cow manure needs to be further dried to reduce moisture content and facilitate subsequent processing. It can be done by sun exposure or using an organic fertilizer dryer.

4. Crushing

Send the dried cow manure into an organic fertilizer grinder and grind it to a certain fineness to prepare for granulation.

5. Mixing

In the mixer, the crushed cow manure is mixed with auxiliary materials (such as straw powder, rice husk powder, etc.) and other organic matter to ensure uniform distribution of ingredients.

6. Granulation

Application granulators, such as roller extrusion granulators or disc granulators, process mixed materials into granules. Choose the appropriate granulation technology based on the characteristics of different equipment and raw materials.

7. Cooling and hardening

Freshly produced particles need to be cooled or naturally air dried to enhance their hardness and reduce the rate of damage.

8. Screening

Use a vibrating screen to separate particles of different sizes to ensure consistent particle size in the final product.

9. Packaging

Use an automatic packaging machine to bag granular fertilizers according to the predetermined weight, label them properly, and prepare them for storage or export.

10. Storage and delivery

The packaged organic fertilizer should be stored in a cool and dry place until it is sold or distributed to farmers for use.

Additional steps: Quality inspection

There is usually a laboratory on the production line responsible for regularly analyzing the chemical composition of finished products to ensure the quality and safety of fertilizers.

Overall, the operation process of the cow manure organic fertilizer production line is a combination of scientific management and technological innovation, which not only focuses on the protection of the ecological environment, but also pursues the maximization of economic benefits, providing strong support for promoting the sustainable development of modern agriculture.
