Process flow of harmless processing of organic fertilizers from chicken manure

 The process flow of harmless processing of organic fertilizers from chicken manure aims to transform this agricultural waste into safe and environmentally friendly organic fertilizers. This process includes multiple steps such as collection, pretreatment, harmless treatment, fermentation, post-treatment, and packaging of chicken manure, ensuring that the final product is both nutritious and harmless to the environment and human health. The following is the specific process flow of the organic fertilizer production line:

1. Collection and pretreatment of chicken manure

Collection: Regularly collect fresh or semi dry chicken manure from the chicken coop.

Screening and crushing: Use a screening machine to remove impurities such as plastics, stones, etc. from chicken manure, and then use an organic fertilizer grinder to crush it to improve subsequent fermentation efficiency.

2. Harmless treatment

High temperature fermentation: The crushed chicken manure is piled up into a fermentation pile, which is periodically flipped by a turning machine to ensure uniform oxygen supply and temperature inside the fermentation pile. The high temperature generated during the fermentation process (usually exceeding 55 ° C) can effectively kill harmful organisms such as pathogens and parasitic eggs in chicken manure, achieving harmless treatment. The fermentation cycle is generally 2-4 weeks.

3. Fermentation

Adding auxiliary materials: In order to adjust the carbon nitrogen ratio of the fermentation pile and promote microbial activity, auxiliary materials such as straw powder and sawdust can be added to chicken manure.

Monitoring and adjustment: During the fermentation process, temperature, humidity, and oxygen levels need to be monitored and adjusted as necessary to ensure the smooth progress of the fermentation process.

4. Post processing

Drying and screening: Fermented chicken manure needs to be dried naturally or using an organic fertilizer dryer to reduce moisture content to a suitable level for granulation. Then use a screening machine to remove large particles or impurities that have not been completely decomposed.

Granulation: Use an organic fertilizer granulator to process processed chicken manure into granules for easy storage, transportation, and application.

Cooling and coating (optional): Granulated chicken manure organic fertilizers may require cooling to prevent clumping due to high temperatures during storage and transportation. In addition, to improve the physical properties of fertilizers, such as moisture resistance and storage stability, coating treatment can be chosen for fertilizer particles.

5. Packaging and Storage

Finished product packaging: The cooled chicken manure organic fertilizer particles are quantitatively packaged using an automatic weighing and packaging machine, ready for sale or storage.

Storage: Store the packaged chicken manure organic fertilizer in a ventilated and dry warehouse, avoiding direct sunlight and humid environments to maintain the quality and effectiveness of the fertilizer.

Through the above process, the harmless processing of chicken manure into organic fertilizers not only solves the problem of chicken manure treatment, but also provides high-quality organic fertilizer sources for agricultural production, realizes the resource utilization of agricultural waste, and promotes the sustainable development of agriculture.

  There is a huge demand for bio organic fertilizers in China, especially for some economically efficient and high-quality bio organic fertilizers, which are more popular among farmers. Therefore, opening an organic fertilizer equipment processing fertilizer factory can yield substantial returns. Organic fertilizer trading market. The production of green fruits and vegetables cannot be separated from organic fertilizers. A large amount of organic fertilizer is piled up and wasted in urban areas, and there is a huge demand gap for organic fertilizer in rural areas. If a rural organic fertilizer trading market is established, a bridge between supply and demand can be established, and the production of organic fertilizer through processing of bio   organic fertilizer equipment   can turn waste into treasure. How much does the entire set of equipment for processing bio organic fertilizers cost? 1. Determine the size of  organic fertilizer equipment , such as the annual p...

Main production process guidance of organic fertilizer production equipment

Image
  Organic fertilizer is a natural fertilizer, but also an important part of sustainable development of human agriculture, so people pay more and more attention to the production of organic fertilizer. The following introduces the main production process of  organic fertilizer production equipment  and the relevant situation of organic fertilizer fermentation equipment. Organic fertilizer production process is generally divided into: fermentation, crushing, ingredients, mixing, molding, drying, cooling, screening, packaging. Of course, some high-end fertilizers will add slurry to make the fertilizer look more beautiful. 1. The first is the fermentation equipment. Most organic fertilizer manufacturers will use the composting fermentation. The key point of composting fermentation is the strain. Only when there are good strains can we get high-quality organic fertilizer. Then there is the crushing equipment. The more commonly used crushing equipment in the organic fertilizer ...
