Prepare Poultry Manure for Efficient Organic Fertilizer Processing

Fresh poultry manure contains a high level of moisture, which makes storage, transport, screening, blending, granulation, and bagging more difficult. For fertilizer producers and commercial poultry farms, the challenge is not only to reduce manure volume, but also to create a more stable raw material for the next production stage.

Lonsin designs a Poultry Manure Drying System for Organic Fertilizer to connect manure collection, sealed conveying, continuous drying, storage, and downstream fertilizer processing.

The system reduces fresh poultry manure moisture from approximately 70–80% to a lower and more manageable level, typically around 20% or below depending on project conditions. The dried material can then be transferred to covered storage, screening, blending, composting, granulation, packaging, or other fertilizer production steps.

From Wet Poultry Manure to Fertilizer Feedstock

A manure dryer is not a complete fertilizer plant by itself. It is the moisture-reduction stage that helps make the overall fertilizer process more stable, efficient, and easier to control.

This process helps transform wet poultry manure from a difficult-to-handle farm by-product into a lower-moisture material suitable for further fertilizer processing.

Why Dry Poultry Manure Before Fertilizer Processing?

Reduce Material Weight and Storage Pressure

Fresh poultry manure contains a large amount of water. Drying reduces the weight that must be stored, loaded, transported, or transferred between processing stages.

Improve Material Handling

Wet manure can stick to conveyors, hoppers, screens, and mixing equipment. Lower-moisture material is generally easier to convey, store, and feed into downstream machinery.

Support More Consistent Fertilizer Processing

A stable moisture range helps improve the control of screening, mixing, fermentation, granulation, and packaging operations.

Reduce Wet Manure Accumulation

Continuous drying reduces the amount of fresh manure waiting in storage areas, helping farms and fertilizer plants organize their material flow more effectively.

Prepare Material for Value-Added Processing

Dried poultry manure can be used as feedstock for organic fertilizer products, soil amendment materials, blended fertilizers, pelletized products, or bagged agricultural inputs, subject to local regulations and product requirements.

Lonsin Poultry Manure Drying Process

1. Manure Collection

Fresh poultry manure is collected from manure belts, scraper systems, pits, or centralized transfer points.

2. Sealed Conveying

The manure is moved to the drying system through a sealed conveying route. This reduces unnecessary manual handling and limits exposed wet manure during transfer.

3. Even Material Distribution

Before drying, the material is spread evenly across the drying surface. A consistent manure layer helps improve airflow contact and moisture removal.

4. Multi-Layer Continuous Drying

The manure moves through one or more chain-plate drying layers. Heated air passes through the material bed while the conveyor system moves the manure forward continuously.

5. Discharge and Downstream Transfer

After drying, the manure can be discharged to covered storage or directly transferred to fertilizer processing equipment.

Reference Moisture Reduction and Material Balance

The final moisture target should be selected according to the next process. For example, material intended for storage, granulation, or pelletizing may require a different moisture range from material intended for composting or blending.

Match the Dryer to Your Fertilizer Production Goal

For Covered Storage and Bulk Sale

A lower-moisture output helps reduce storage volume and simplifies loading, transport, and delivery to agricultural users or fertilizer processors.

For Organic Fertilizer Blending

Dried poultry manure can be used as a base organic material for blending with other composted materials, minerals, microbial products, or agricultural residues.

For Composting and Fermentation

Drying can help improve moisture control before composting or fermentation. The final process should still be designed around material composition, aeration, retention time, temperature control, and local product requirements.

For Granulation or Pelletizing

For fertilizer granulation and pellet production, moisture control is essential. The manure drying system prepares a more manageable feedstock before crushing, mixing, granulating, drying, cooling, and packaging.

For Bagged Fertilizer Products

Lower-moisture manure can be screened, blended, processed, and packed into retail or wholesale fertilizer bags after the required quality control, nutrient testing, and regulatory procedures.

Suggested System Configurations

Reference Capacity Direction

Lonsin’s reference configurations include approximately 6,000 kg/day single-tier and 12,500 kg/day double-tier drying systems. Final capacity depends on manure moisture, daily operating hours, available heat source, installation space, and required output moisture.

Heat Source Options for Fertilizer Projects

The drying system can be configured according to local energy conditions and available farm resources.

• Poultry house ventilation exhaust air

• Biomass heating

• Natural gas

• LPG

• Coal or briquette heating

• Electric heating

• Hybrid waste heat plus auxiliary heat configuration

For poultry farms with suitable ventilation airflow, warm exhaust air from poultry house fans can support manure drying and reduce supplemental heating demand. For fertilizer plants, centralized treatment facilities, cold regions, or high-humidity areas, an independent or hybrid heat source may be more suitable.

What Can Be Customized?

Lonsin designs the manure drying system around the actual fertilizer process and site conditions.

Customization can include:

• Daily manure processing capacity

• Dryer length, width, and number of layers

• Fresh manure feeding and transfer method

• Sealed conveyor layout

• Waste heat recovery or independent heating configuration

• Temperature, humidity, and conveyor-speed monitoring

• Manual, semi-automatic, or fully automatic control

• Storage hopper and discharge conveyor direction

• Connection to screening, mixing, granulation, or bagging equipment
