Animal manure is no longer just waste—it’s a powerful organic resource for producing high-quality bio fertilizer. With the help of microbial inoculants and professional equipment, you can convert livestock waste into sustainable, nutrient-rich products for agriculture. This article explains how to make bio fertilizer from animal manure, focusing on each processing step and the essential equipment involved in a modern biofertilizer production line.
1. Preprocessing: Solid-Liquid Separation
Purpose:
Raw animal manure contains excessive moisture and bulky particles, which must be reduced before composting.
Key Equipment:
-
Solid-liquid separator: Efficiently separates water and solid content, reducing moisture to 50–60%.
-
Straw shredder or crusher: Optional equipment for breaking down bedding material or carbon additives.
This step prepares the raw material for microbial fermentation.
2. Composting with Microbial Inoculants
Purpose:
Aerobic composting decomposes organic matter, eliminates pathogens, and prepares the base for bio fertilizer.
Key Equipment:
-
Compost turner: Available in groove, windrow, or crawler types to improve oxygen flow and temperature balance.
-
Composting control system: Tracks heat and moisture levels in real-time.
Microbial Inoculant Addition:
During composting, commercial microbial agents (e.g., Bacillus, Actinomycetes) are added to accelerate decomposition, suppress harmful microbes, and enrich the biofertilizer with beneficial organisms.
3. Post-Fermentation Crushing and Mixing
Purpose:
Once composting is complete, the material is loose and uneven. It must be crushed and mixed for uniform granulation.
Key Equipment:
-
Semi-wet material crusher: Grinds fermented manure into fine powder.
-
Horizontal mixer: Ensures even distribution of nutrients and any secondary microbial agents.
At this stage, microbial inoculants that are heat-sensitive can be introduced before pelletizing.
4. Granulation of Bio Fertilizer
Purpose:
Granulation enhances usability, packaging, and transport, while protecting the microbial content.
Key Equipment:
-
Biofertilizer granulator machine: Disc granulator, rotary drum, or new-type granulators are commonly used.
-
Moisture controller: Keeps material within ideal range for granulation (usually around 30%).
Granules provide better microbial stability compared to loose powders. Click here to get more!
5. Drying, Cooling, and Screening
Purpose:
Removes excess moisture while keeping beneficial microbes alive.
Key Equipment:
-
Rotary dryer: Operates at controlled, low temperatures to preserve bioactivity.
-
Rotary cooler: Rapidly cools down granules post-drying.
-
Screening machine: Removes oversized or undersized particles, sending them back for reprocessing.
Temperature control is key when working with biofertilizer making line that involve living microbes.
6. Coating and Packaging
Purpose:
Protect the final product and extend shelf life.
Key Equipment:
-
Coating machine (optional): Applies anti-caking or moisture-proof agents.
-
Fertilizer packaging line: Automated system for weighing, bagging, sealing, and palletizing bio fertilizer granules.
Packaging helps preserve microbial effectiveness during transport and storage.
Conclusion
Understanding how to make bio fertilizer from animal manure is essential for sustainable agriculture and waste recycling. By integrating microbial inoculants at the right stages and using dedicated machinery, producers can generate high-quality biofertilizers that support soil health and crop productivity.
