With the rapid development of animal husbandry, a large amount of feces and sewage have been generated. The harmful elements in these feces seriously exceed the standard, making it difficult to treat them with traditional methods of returning them to the fields. In response to this situation, people have developed organic fertilizer equipment with mobile and efficient solid-liquid separation technology as the core, integrating and supporting efficient mixer, flipper, granulator and other fertilizer production equipment.
The development and development of large-scale organic fertilizer equipment and sterilization systems will be conducive to promoting the formation of an industrial chain for harmless treatment, resource utilization, and commercialization of livestock and poultry manure, achieving the goals of industrialization, marketization, and large-scale production, and effectively promoting the development of ecological agriculture and circular economy in the city.
Large organic fertilizer equipment is a type of equipment that uses chicken and pig manure as the main raw materials, adds a certain amount of nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer, magnesium sulfate, ferrous sulfate, and other substances, and ferments rice bran, yeast, soybean meal, and sugar for a certain period of time as biological bacteria. Under the action of sulfuric acid, it is mixed and fermented to produce biological fertilizer. It has not only created economic benefits for enterprises, but also made significant contributions to human environmental protection projects.
The process flow of a complete set of organic fertilizer granulation equipment:
- Firstly, raw materials such as animal manure are fermented and decomposed. The entire fermentation process can kill harmful bacterial communities inside, which is also the most important step in the entire organic fertilizer production process.
- Secondly, it is necessary to use an organic fertilizer crushing equipment, a semi wet material crusher, to preliminarily decompose the raw materials.
- Matching raw materials is one of the crucial processes in the production of organic fertilizers. Its main purpose is to add an appropriate amount of auxiliary materials according to the formula ratio to improve the quality of fertilizer.
- Mechanical granulation is the most crucial aspect of the entire production process, as the material preparation is evenly mixed and stirred.
- After the raw material undergoes the drying step to obtain high-temperature energy, the next step requires low-temperature cooling. Since water cannot be used for cooling, a cooling machine equipment is needed to separate the contact between the material and water.
- Screening is to screen out unqualified fertilizer particles, and the screening equipment here has the advantages of high efficiency and easy operation.
- Generate the prepared raw materials into granules that are needed, especially suitable for materials with high viscosity.
