(FAQ)What type of production line is recommended for a chicken farm?

Chicken farms generate large quantities of manure daily; characterized by high moisture content, high nitrogen levels, and strong odors, raw manure can easily burn crop roots if applied directly to the soil. Establishing an organic fertilizer production line using chicken manure not only alleviates environmental pressure but also generates additional revenue. Different scales of operation suit different production approaches: 1.Powdered Organic Fertilizer Line—Small-scale entry Suitable for flocks of fewer than 50,000 birds. The process involves: solid-liquid separation → moisture and C/N ratio adjustment (adding straw or rice husks) → aerobic fermentation → windrow turning → maturation → crushing and screening → packaging. This option requires low investment and is simple to operate; the product can be sold to local orchards and vegetable growers. Key equipment includes the solid-liquid separator and the windrow compost turner; uniform turning is essential to ensure the destruction of pathogens and parasite eggs. 2.Granular Organic Fertilizer Line—Medium-scale upgrade Suitable for flocks of 50,000 to 200,000 birds. This setup builds upon the powdered fertilizer process by adding a disc granulator, a dryer-cooler, and a screening machine. Once decomposed, chicken manure has ideal viscosity and fine texture, resulting in a high pelletization rate; the granules are round, aesthetically pleasing, and convenient for transport and mechanical sowing, commanding a higher market price. Moisture content should be controlled at 25%–35% prior to granulation. 3.Bio-organic Fertilizer Production Line—High value-added approach Functional microbial strains are added before granulation to produce bio-organic fertilizer. The key lies in maintaining low temperatures throughout the process: disc granulation generates no extrusion heat, and when combined with low-temperature drying (≤50°C), the survival of the microbial strains is ensured. While this process demands stricter operational standards, the product commands a significant price premium. 4.Selection Recommendations Consider flock size first, followed by available capital and sales channels. Start with powdered fertilizer for small-scale operations; opt for a granular line for medium-scale operations; and pursue bio-organic fertilizer production only if the necessary technical capabilities are in place. Regardless of the line chosen, proper fermentation and maturation form the foundation—thorough turning and achieving the required temperatures ensure that subsequent crushing and granulation proceed smoothly.
