The products produced by the organic fertilizer production line are made from fresh chicken manure, pig manure, cow manure, and other animal manure as raw materials, which can be mixed with plant-based materials such as crop straw. They do not contain any chemical components and have poor digestion ability for chickens and pigs. They can only consume 25% of the nutrients, while the other 75% of the nutrients in the feed are excreted with the manure, resulting in dry products containing nitrogen, phosphorus, potassium, organic matter, amino acids, proteins, and other components. The chicken manure dryer has not only created economic benefits for enterprises, but also made significant contributions to human environmental protection projects

The sources of raw materials for producing organic fertilizers are as follows:

1. Agricultural waste: such as straw, soybean meal, cotton meal, etc.

2. Livestock and poultry manure: such as chicken manure, cow, sheep, horse manure, rabbit manure;

3. Industrial waste: such as distillers grains, vinegar residue, cassava residue, sugar residue, furfural residue, etc;

4. Household waste: such as kitchen waste, etc;

5. Urban sludge: such as river silt, sewer silt, etc. A comprehensive classification of organic fertilizer raw material production and supply bases: silkworm excrement, mushroom residue, kelp residue, phosphate citric acid residue, cassava residue, protein paste, sugar aldehyde residue, amino acid humic acid, oil residue, plant ash, shell powder, etc., as well as peanut shell powder.

working principle

With the rapid development of animal husbandry, a large amount of feces and sewage have been generated. The harmful elements in these feces are severely excessive and difficult to treat with traditional returning methods. In response to this situation, people have developed organic fertilizer production lines with movable and solid-liquid separation technology as the core, integrating supporting fertilizer production equipment such as mixers, turners, and granulators. The development and research of organic fertilizer production lines and sterilization systems for livestock and poultry manure will be conducive to promoting the harmless treatment, resource utilization, and commercialization of livestock and poultry manure production chains, achieving industrialization, marketization, and large-scale production goals, and effectively promoting the development of ecological agriculture and circular economy in the city.

The process flow of the organic fertilizer production line for chicken manure and other animal manure roughly includes: raw material selection (chicken manure, etc.) → dryer → ingredient mixing → granulator → cooling and screening → metering and sealing → finished product storage.

The more complex production process of chicken manure organic fertilizer is as follows: the organic fertilizer raw materials (animal manure, household waste, dead branches and leaves, biogas residue, waste bacterial strains, etc.) are fermented and then enter a semi wet material crusher for crushing. Then, nitrogen, phosphorus, potassium and other elements (pure nitrogen, phosphorus pentoxide, potassium chloride, ammonium chloride, etc.) are added to meet the required standards of mineral elements. The mixture is then stirred by a mixer and enters the granulation mechanism for granulation. After coming out, it is dried and screened by a screening machine. Qualified products are packaged, and unqualified products are returned to the granulator for granulation.

The reasonable combination of raw material fineness is crucial for the process flow of organic fertilizer production line. The fineness of the entire raw material should be matched as follows: 100-60 mesh raw material accounts for about 30% -40%, 60 mesh to 1.00mm diameter raw material accounts for about 35%, and small particles with a diameter of 1.00-2.00mm account for about 25% -30%. The higher the material fineness, the better the viscosity, and the higher the surface smoothness of the particles after granulation. However, in the production process, the use of excessive proportion of high fineness materials can easily lead to problems such as oversized and irregular particles due to poor viscosity.
