| 1. Manure Deposition | Manure belt installed beneath each cage tier | Bird droppings fall through the cage floor and land directly on the moving or stationary belt below the cages. | Usually one belt is installed beneath each cage tier; belt widths commonly range from approximately 1.0 to 2.5 m, depending on the cage layout. | Manure is isolated from the house floor, reducing direct contact with litter and simplifying removal. |
| 2. Temporary Holding | Polypropylene or polyethylene belt | The belt supports the manure between removal cycles. Its smooth surface allows the material to be carried without requiring a floor scraper. | Common belt thicknesses are approximately 0.8–2.0 mm; belt selection should consider tensile strength, flexibility, cleaning, and resistance to moisture and ammonia. | A continuous collection surface is provided under the cages, with less accumulation on building surfaces. |
| 3. Manure Removal | Drive roller, motor, gearbox, and belt-control system | An electric motor turns the drive roller, pulling the belt lengthwise and moving manure toward the end of the cage row. | A typical belt speed is approximately 5–20 m/min when operating; the actual speed is selected to prevent overloading, tearing, or excessive spillage. | Manure can be removed mechanically with limited manual handling. |
| 4. Removal Scheduling | Timer, control panel, or manual start-stop control | The belt is operated at planned intervals so that manure does not remain under the cages longer than necessary. | Removal may be scheduled daily, several times per week, or according to manure loading and farm management requirements. | More frequent removal generally reduces storage time, odor generation, and the opportunity for moisture migration. |
| 5. Belt Cleaning | Belt scraper or cleaning blade | A scraper positioned near the discharge end removes manure that remains attached to the belt surface as the belt returns. | The scraper should maintain uniform contact without cutting, folding, or excessively wearing the belt. | Cleaner belt return paths help reduce carryback, buildup, and spillage around the conveyor. |
| 6. Horizontal Transport | Cross conveyor or transfer conveyor | At the end of each cage row, manure drops onto a cross conveyor that combines material from multiple tiers or rows. | The cross conveyor is sized according to the number of cage rows, manure loading, conveyor length, and available discharge space. | Manure from several belts can be directed to one centralized discharge point. |
| 7. Vertical Transfer | Inclined conveyor or manure elevator | Where the storage or loading area is at a different elevation, an inclined conveyor lifts the manure from the cross conveyor to the discharge point. | Inclination and speed must be matched to manure consistency to limit rolling, sliding, and material falling from the belt. | The system can move manure out of the poultry house without relying on a tractor inside the building. |
| 8. Final Collection | Trailer, manure cart, covered bay, or temporary storage area | The discharge conveyor deposits manure into a receiving container or designated storage area for later transport, composting, drying, or land application. | Collection capacity should be greater than the expected manure volume between removal and hauling cycles. | The final collection point allows loading, transport, and further nutrient-management processing to be organized safely. |
| 9. Moisture and Odor Control | Ventilation, timely removal, and optional belt-drying airflow | Removing manure promptly and maintaining adequate ventilation helps limit moisture accumulation and the formation of odor-producing anaerobic conditions. | Manure moisture varies with bird diet, water spillage, ventilation, climate, and storage time; no single moisture value applies to every farm. | Drier manure is generally easier to handle and transport and may have improved value for composting or fertilizer use. |
| 10. Routine Inspection | Belt alignment devices, bearings, guards, and emergency stops | Operators check belt tracking, roller condition, scraper contact, motor load, loose fasteners, and accumulated manure before and during operation. | Inspection frequency should follow operating hours, manufacturer instructions, site conditions, and applicable workplace-safety requirements. | Regular maintenance helps prevent belt misalignment, blockages, unplanned downtime, and unsafe access to moving parts. |
