A layer farm produces manure every day, often across multiple poultry houses and manure belt lines. Without a continuous treatment system, wet manure can quickly occupy storage space, increase transport weight, create odor concerns, and complicate downstream fertilizer handling.
Lonsin designs a Layer Farm Manure Drying System around your flock size, daily wet manure output, poultry house ventilation conditions, available installation space, and intended use of the dried material.
The system uses sealed conveying, even material distribution, and multi-layer chain-plate drying to reduce fresh layer manure moisture from approximately 75–80% to 20% or below. The dried material can then be transferred to covered storage, bagging, organic fertilizer processing, or pelletizing systems.

Layer manure is generated continuously, not seasonally. For farms with multiple houses and large flock numbers, storing wet manure for long periods can create several operational challenges:
Wet manure occupies more space than dried manure.
High moisture increases transport weight and hauling frequency.
Delayed handling can increase odor and hygiene pressure around manure collection areas.
Inconsistent moisture makes storage, bagging, screening, and further fertilizer processing more difficult.
Manual handling becomes inefficient as flock size and manure output increase.
A laying hen manure drying system creates a more controlled route from collection to final storage. Instead of allowing fresh manure to accumulate in pits, stacks, or open areas, the system continuously moves manure through drying layers and discharges a lower-moisture material ready for the next processing stage.
Drying does not replace all farm environmental controls. Odor, dust, and emissions performance also depends on collection frequency, ventilation, storage design, local climate, and site-specific regulations.
For early project planning, a commercial layer farm can use the following estimate:
Estimated fresh manure output per day = Number of laying hens × 0.10–0.12 kg
This is a planning range for collected fresh manure. Actual output can vary with feed formulation, bird age, manure belt frequency, moisture content, spilled water, feathers, feed loss, and whether other materials enter the collection system.
| Layer Farm Size | Estimated Fresh Manure Output | Suggested Drying Direction | Typical Layout Direction |
|---|---|---|---|
| 30,000–60,000 layers | 3–7 tons/day | Single-tier reference system or customized compact unit | Long, low-height installation |
| 60,000–100,000 layers | 6–12 tons/day | Customized single-tier or compact double-tier solution | Depends on available length and height |
| 100,000–125,000 layers | 10–15 tons/day | Double-tier system or capacity-adjusted configuration | Limited floor space, available building height |
| 125,000–200,000 layers | 12.5–24 tons/day | Multi-tier system, expanded double-tier system, or parallel lines | Large-scale centralized manure treatment |
| Over 200,000 layers | Project-specific | Multiple modules or high-capacity custom system | Centralized farm or group-farm project |
| Reference Configuration | Daily Processing Capacity | Drying Layers | Reference Footprint | Installed Power | Reference Running Consumption |
|---|---|---|---|---|---|
| Single-tier system | 6,000 kg/day | 1 layer | 30 m × 4.5 m × 3 m | 45 kW | Approx. 30 kWh per operating hour |
| Double-tier system | 12,500 kg/day | 2 layers | 30 m × 4.5 m × 6 m | 90 kW | Approx. 37.5 kWh per operating hour |
| Custom project system | Based on farm output | 1–4 layers | Designed around site conditions | Customized | Based on heat source and automation level |
The 6,000 kg/day and 12,500 kg/day configurations are reference points, not fixed product limits. Lonsin can adjust conveying capacity, drying layers, machine length, automation level, and heat source according to the actual project.
Moisture removal significantly reduces the amount of material that must be stored, loaded, and transported.
| Fresh Manure Input | Input Moisture | Dry Manure Output at 20% Moisture | Approximate Mass Reduction |
|---|---|---|---|
| 6 tons/day | 75–80% | Approx. 1.5–1.9 tons/day | Approx. 69–75% |
| 12.5 tons/day | 75–80% | Approx. 3.1–3.9 tons/day | Approx. 69–75% |
| 20 tons/day | 75–80% | Approx. 5.0–6.3 tons/day | Approx. 69–75% |
This calculation is based on moisture balance only. Final volume, bulk density, and storage space requirements will vary depending on particle size, material structure, compaction, and packaging method.
For a layer farm, lower-moisture manure can help reduce:
The area needed for temporary manure storage
The number of wet-manure truckloads
The weight handled during loading and transport
The risk of long-term wet manure accumulation
The difficulty of supplying consistent material to fertilizer processing equipment

Fresh manure is collected from manure belts, scraper systems, or centralized transfer points. The collection stage should be designed to reduce excessive water entry and maintain a consistent material flow into the dryer.
The manure is transferred through a sealed conveyor system to reduce manual handling and minimize exposed wet manure during transport. Conveyor structure and transfer direction can be adjusted to match the poultry house layout.
Before drying, manure is spread evenly across the width of the drying layer. Stable layer thickness helps reduce wet spots and improves consistency at the discharge end.
The material moves through one or more stacked chain-plate drying layers. Heated air passes through the manure bed, removing moisture continuously as the material travels through the system.
Once the target moisture is reached, the manure is discharged continuously. It can be transferred to covered storage, bagging equipment, fertilizer processing lines, or pelletizing systems.
Many layer houses already use ventilation fans to remove warm, moisture-laden air from the poultry environment. Where airflow volume, temperature, and house layout are suitable, this exhaust air can be directed into the manure drying system as a heat source.
Rather than relying only on new fuel input, the dryer can use available warm ventilation air to support moisture removal.

Exhaust discharge and local environmental requirements
Warm exhaust air can reduce supplemental heating demand, but it does not mean the complete system operates without electricity. Conveyors, control systems, distribution equipment, sensors, and optional heat units still require power.
For farms with insufficient waste heat, Lonsin can configure additional biomass, natural gas, LPG, coal/briquette, or electric heating according to local energy conditions and project requirements.
A single-tier configuration is suitable for farms with sufficient installation length and limited building height.
Best suited for:
Farms with long, narrow installation areas
Projects with around 6 tons/day of fresh manure handling demand
Sites with lower building clearance
Farms that prefer straightforward access for operation and maintenance
Initial projects that may later expand with an additional module
Reference footprint:
30 m × 4.5 m × 3 m
A double-tier configuration increases capacity while using approximately the same floor area as a single-tier layout.
Best suited for:
Farms with limited floor area but sufficient installation height
Layer farms handling approximately 10–12.5 tons/day or more
Centralized manure treatment areas serving multiple poultry houses
Projects requiring higher capacity without extending machine length
Farms planning automated monitoring and fault alarm functions
Reference footprint:
30 m × 4.5 m × 6 m
For large layer farms, multi-tier structures or multiple drying lines can be designed to match higher manure output and future expansion plans.
Best suited for:
Farms with more than 125,000 laying hens
Sites with centralized manure treatment buildings
Projects with 15+ tons/day of fresh manure output
Farms serving multiple houses or production zones
Organic fertilizer and poultry waste resource utilization projects
Final layer quantity should be determined by output demand, available height, maintenance access, heat source, daily operating hours, and future farm expansion plans.
A layer farm manure drying system supports a cleaner manure handling route by reducing the time that fresh manure remains in collection and storage areas.
Drying reduces the mass of water carried with the manure. This allows farms to store more material within the same covered storage area.
Continuous collection and sealed conveying reduce the need to move wet manure manually between houses, pits, stockpiles, and transport vehicles.
By removing moisture before transport, each truckload can carry more usable dry material and less water weight.
A more stable moisture range helps prepare manure for screening, blending, bagging, organic fertilizer processing, or pelletizing.
By reducing fresh manure accumulation, farms can better organize collection zones, storage areas, and traffic routes around poultry houses.
Lonsin develops each solution around the farm’s manure handling route rather than offering only one fixed machine size.
A preliminary capacity and layout proposal can include:
Estimated daily manure handling capacity
Recommended dryer tier structure
Suggested machine footprint
Preliminary flow from poultry houses to dryer
Waste heat recovery concept using poultry house fans
Independent heating options where needed
Recommended dry manure discharge route
Automation level recommendation
Reference power requirement
Preliminary quotation direction
Lonsin also supplies poultry house-related equipment and farm materials, allowing the drying system to be considered together with ventilation and farm infrastructure requirements.
The system is most suitable for commercial layer farms with consistent daily manure output. Farms with around 30,000–60,000 layers can begin with a compact or single-tier solution, while larger farms may require double-tier, multi-tier, or parallel drying lines.
The starting point is daily fresh manure output, not flock size alone. For early planning, use approximately 0.10–0.12 kg of collected fresh manure per laying hen per day, then confirm the actual collection method, input moisture, operating hours, and future capacity margin.
Yes. Where fan airflow, temperature, duct distance, and site layout are suitable, warm exhaust air from poultry house ventilation fans can be used to support the drying process. Supplemental heating can be added where waste heat is insufficient.
A single-tier system requires less installation height and is suitable for sites with sufficient length. A double-tier system increases capacity within a similar floor area but requires greater building height.
No. The system is designed for continuous drying and does not require additives for the drying process.
Yes. After moisture reduction, the material can be transferred to covered storage. Final storage conditions should be planned according to local climate, material temperature, handling method, and end-use requirements.
It can be used as feedstock for organic fertilizer processing or agricultural applications, subject to local fertilizer regulations, nutrient testing, hygiene requirements, and product registration rules.
Yes. For farms with planned flock growth, Lonsin can evaluate modular expansion, additional drying layers, larger conveying capacity, or parallel dryer lines during the initial layout stage.
