Introduction
If you’re managing large volumes of agricultural waste—such as chicken manure, cow dung, crop residues, or digestate from biogas systems—you’re sitting on a valuable resource. With the right production line, these organic materials can be transformed into high-quality bio organic fertilizer. But the key to success lies in choosing a system that matches your specific raw material characteristics.
In this blog, we’ll explore how different farm wastes affect the design of your biofertilizer production line, and what equipment choices can optimize performance and output.
1. Identify Your Primary Raw Material
Before setting up any production line, it’s essential to know your material. Common types include:
-
Chicken Manure: High in nitrogen but sticky and moist
-
Cow Dung: Fiber-rich and bulky; ideal for composting
-
Biogas Digestate (solid fraction): Moist, fine, and nutrient-dense
-
Crop Straw & Plant Residues: Low in nutrients but useful for bulk and structure
-
Urban Organic Waste: Requires sorting and sterilization before processing

2. Adjust Composting and Pretreatment Methods
Different wastes require different composting strategies:
-
High-moisture materials (e.g., fresh manure, digestate): Use solid-liquid separators or add dry straw to balance moisture.
-
Low-nitrogen residues: Add microbial inoculants or mix with high-nitrogen manure for better composting.
-
Odorous materials: Consider forced aeration systems or enclosed fermentation tanks.
Pretreatment directly impacts granule quality and system efficiency down the line.
3. Choose the Right Granulation System
Based on your material’s texture and moisture, choose the appropriate granulator:
| Raw Material Type | Best Granulation Option |
|---|---|
| Chicken manure + straw | Disc Pelletizer |
| Cow dung + digestate | Rotary Drum Granulator |
| Fine dry powders | Roller Compactor Granulator |
| Sticky, high-moisture mix | Pan Granulation with Drying Line |
Choosing the right system avoids clogging, ensures pellet uniformity, and saves energy. If you don’t know how to choose the right biofertilizer production equipment, welcome to consult YUSHUNXIN!
4. Don’t Forget Post-Treatment
Regardless of the raw material, post-processing is crucial:
-
Drying & Cooling: Needed for higher-moisture granules (e.g., from drum or pan pelletizers)
-
Screening: To separate qualified granules from powder or oversized particles
-
Coating & Packaging: Improves storage and prevents moisture absorption
Well-finished granules increase market value and shelf life.
Conclusion
No two farms produce the same waste, and no two biofertilizer lines should be exactly alike. By analyzing your raw material characteristics, you can design a production line that’s energy-efficient, cost-effective, and built for long-term success.
