Poultry farms generate vast quantities of fresh chicken manure daily. While rich in organic nitrogen, phosphorus, and potassium , raw chicken manure cannot be applied directly to crops due to high salt concentration, weed seeds, pathogens like E. coli, Salmonella , and intense ammonia odor.
Converting raw chicken dung into high-grade, commercial bio-organic fertilizer pellets is one of the most profitable investments for farming enterprises and organic fertilizer plant investors.
In this comprehensive engineering guide, we walk you through the complete chicken manure organic fertilizer production line , detailing the exact process from raw waste dewatering to final pellet packaging.
⚡ EXECUTIVE SUMMARY & ROI HIGHLIGHTS
- Moisture Control is Essential: Fresh chicken manure typically contains 70%–80% moisture. It must be dewatered down to 50%–60% before composting, and 25%–30% before granulation.
- Fermentation Kills Pathogens: Aerobic composting at temperatures between 55°C and 65°C for 7–12 days is required to eliminate harmful bacteria (E. coli, Salmonella) and weed seeds.
- Granulator Selection: For organic chicken manure, a New-Type Organic Fertilizer Granulator or a Disc/Pan Granulator delivers superior pellet shape and density compared to traditional rollers.
- Target Return on Investment: A standard 1–3 ton/hour chicken manure fertilizer line can reach full ROI within 12–18 months of continuous operation.
Step 1: Raw Material Preparation & C:N Ratio Adjustment
Raw chicken manure has a low Carbon-to-Nitrogen (C:N) ratio (around 10:1) and high moisture (70%–80%). To optimize aerobic composting:
- Recommended Machine:Use a Screw Extrusion Solid-Liquid Separator to reduce moisture to 50%–50%.
- Carbon Supplement: Mix raw manure with dry organic carbon materials like crop straw, sawdust, or corn stalks to adjust the C:N ratio to 25:1–30:1.
Step 2: High-Efficiency Aerobic Fermentation & Deodorization
Fermentation kills weed seeds and harmful pathogens while stabilizing organic matter:
- Recommended Machine:Use a Screw Extrusion Solid-Liquid Separator to reduce moisture to 50%–50%.
- In-Vessel Fermentation Tank: Best for modern enclosed plants. Achieves complete deodorization and sterilization within 7–10 days under continuous 55°C–65°C aerobic heat.
Step 3: Crushing & Formula Batching
Once composted, cured manure drops to 30% moisture with some clumping:
- Use a Semi-Wet Material Crusher to pulverize materials to 2–5 mm fine powder.
- Use a Horizontal Fertilizer Mixer to blend inorganic additives (such as NPK elements or humic acid) for customized chicken manure organic fertilizer formulas.
Step 4: Granulation (Making Chicken Manure Fertilizer Pellets)
Converting powder into pellets improves storage, transport, and commercial resale value:
- New-Type Wet Organic Fertilizer Granulator : Utilizes high-speed mechanical agitation to shape dense, uniform spherical granules with a high yield rate (≥92%).
Step 5: Drying, Cooling & Screening
Newly formed organic granules contain approximately 20%–25% moisture and require drying to ensure long shelf life without mold growth.
- Rotary Drum Dryer: Utilizes hot air from a furnace to reduce granule moisture to < 14%.
- Rotary Drum Cooler: Rapidly lowers pellet temperature to ambient levels, preventing condensation inside bags during storage.
- Rotary Screening Machine: Separates undersized fines and oversized lumps. Fines are automatically returned to the granulator via a recycle belt conveyor.
Step 6: Coating & Automatic Packaging
Finished granules are coated with protective anti-caking agents or micro-organisms before being automatically weighed and packed into 25kg or 50kg bags using an automated packaging machine.

Frequently Asked Questions (FAQ)
Q1: What is the cost to start a small-scale chicken manure organic fertilizer plant?
A small-scale plant (annual output of 3,000 to 5,000 tons) typically requires an equipment investment ranging from $20,000 to $45,000, covering dewatering, composting, crushing, granulating, and packaging machines.
Q2: How much raw manure is needed for 1 ton of organic fertilizer pellets?
Due to moisture reduction during solid-liquid separation, composting, and drying, it takes approximately 2.5 to 3.5 tons of fresh chicken manure (75% moisture) to manufacture 1 ton of finished fertilizer pellets (12%–14% moisture).
Q3: How do I control odor in my organic fertilizer factory?
Use pre-dewatering methods, mix dry carbon additives, apply bio-deodorizing bacterial strains during fermentation, and install enclosed fermentation tanks with bio-filter scrubbing systems.
