The process of converting chicken manure into organic fertilizer involves a series of complex steps aimed at transforming chicken manure into efficient, safe, and environmentally friendly fertilizer. The following is the basic process of making organic fertilizer from chicken farm manure:
1. Collection and preprocessing
Chicken manure collection: Regularly clean and collect fresh or air dried chicken manure from the chicken coop.
Preliminary screening: Remove large debris and non organic substances such as plastic bags, metal sheets, etc. to ensure the smooth progress of subsequent processes.
Adjusting moisture content: To determine the moisture content of chicken manure, it is usually necessary to adjust it to an appropriate level, generally recommended between 40% -60%, for subsequent fermentation and granulation.
2. Fermentation and decomposition
Composting preparation: Mix chicken manure with other organic matter (such as straw, rice husk, etc.) to create an aerobic composting environment, accelerate organic matter decomposition, and control pH and temperature to promote beneficial microbial activity.
Fermentation process: Maintain appropriate temperature and ventilation to raise the internal temperature of the chicken manure pile to 60 ℃~70 ℃, lasting for several days to weeks, effectively killing most bacteria, viruses, and parasitic eggs.
3. Adjustment and crushing
Pile turning: Regularly use an organic fertilizer pile turning machine to turn the chicken manure pile, ensuring sufficient oxygen, accelerating decomposition rate, and evenly dissipating heat.
Crushing: After fermentation is completed, the matured chicken manure material is crushed using an organic fertilizer grinder to achieve moderate particle size, which is conducive to granulation.
4. Add nutritional supplements
Detection and analysis: Conduct chemical composition analysis on fermented chicken manure to determine whether additional nutrients such as nitrogen, phosphorus, and potassium need to be added to balance the formula.
Mixing ingredients: Based on the test results, appropriate amounts of minerals, trace elements, etc. are mixed to improve the nutritional value of organic fertilizer.
5. Granulation and solidification
Granulation: Use organic fertilizer granulators, such as drum granulators, ring mold granulators, etc., to make the mixture into particles of a predetermined size.
Drying: Place the granulated organic fertilizer in a dryer to reduce moisture content, prevent mold growth, and extend shelf life.
6. Cooling and screening
Cooling: The particles are cooled by a cooler to near room temperature to maintain structural stability and avoid chemical reactions during storage.
Grading: Use a screening machine to remove unqualified large particles or powder residues, ensuring that the final product particles are uniform and consistent.
7. Packaging and Storage
Weighing packaging: Measure and package finished products according to market demand.
Storage management: Store properly in a cool and dry place to prevent moisture and insect infestations.
Through these meticulous steps, chicken manure from chicken farms can be efficiently converted into high-quality organic fertilizers, not only solving the problem of chicken manure treatment, but also providing valuable natural nutrients for agriculture, promoting the development of circular economy.
