Designing a complete organic fertilizer production line involves several key components and processes to ensure efficient and high-quality fertilizer production. Here’s a generalized outline of a 20,000 tons per year organic fertilizer making line design:

1. Raw Material Handling and Preprocessing:

Collect organic materials such as crop residues, animal manure, kitchen waste, etc. For organic fertilizer making with a capacity of 20,000 t/y, you may need to prepare 100-200 tons of materials per day. Eapecially when you use animal manure as fertilizer.
Sort and separate materials to remove contaminants like plastics and metals.
Shred or grind large materials to facilitate decomposition.

2. Fermentation Process:

Construct fermentation piles or use fermentation tanks for controlled decomposition.
Mix organic materials with bulking agents like straw or sawdust to create proper carbon-to-nitrogen ratio.
Turn or agitate the piles regularly to ensure even decomposition and aeration.
Monitor temperature, moisture, and pH levels for optimal microbial activity.
With suitable composter for 20,000 t/h organic fertilizer making, fermentation typically takes 2-3 weeks.

3. Crushing and Mixing:

After fermentation, use a crusher to further break down materials into smaller particles.
Mix different fermented materials to achieve a uniform blend and nutrient distribution.
Add mineral additives if necessary to balance nutrient content.

4. Granulation:

Use a granulator or pelletizer to shape the mixed materials into uniform granules.
Adjust particle size by changing the die size in the granulator.
This step increases the convenience of application and reduces nutrient loss.

5. Drying:

Dry the newly formed granules to reduce moisture content and prevent spoilage during storage.
Choose between rotary drum dryers, fluidized bed dryers, or other suitable drying methods.

6. Cooling:

After drying, cool the granules to near-ambient temperature to prepare for packaging.
Cooling also helps improve the quality and shelf life of the final product.

7. Screening and Grading:

Use vibrating screens to remove oversize or undersize granules.
Grade the granules based on size, ensuring consistent quality and application efficiency.
This is important for quality organic fertilizer manfuacturing.

8. Coating and Additives (Optional):

Apply coatings to the granules to enhance their resistance to moisture and reduce dust formation.
Add beneficial microorganisms or bio-stimulants to improve soil health.

9. Packaging:

Pack the finished organic fertilizer into bags, sacks, or other suitable containers.
Label the packages with relevant information about the product.

10. Quality Control and Testing:

Regularly sample and test the fertilizer for nutrient content, moisture levels, and potential contaminants.
Make adjustments to the production process based on testing results.

11. Environmental Considerations:

Design the production line with proper waste management and odor control systems.
Comply with local regulations and best practices to minimize environmental impact.

12. Automation and Safety:

Integrate automation where possible to streamline processes and ensure safety.
Provide proper training for employees to operate machinery and equipment safely.

Remember that the specific design and equipment used can vary based on the availability of resources, budget, and local regulations. It’s recommended to consult with experts in organic fertilizer production and engineering to create a tailored production line design for your needs.
