The process of converting manure from aquaculture farms into organic fertilizers involves multiple steps and requires the use of a series of specialized organic fertilizer production equipment to achieve this transformation. The following is a list and brief description of the main equipment required in a typical organic fertilizer production line:
1. Solid Liquid Separators
Firstly, use a solid-liquid separator to remove excess water from feces, resulting in a relatively dry solid material that is convenient for subsequent processing. This is an important step in the preprocessing stage, which can greatly reduce the pressure and cost of subsequent processes.
2. Fermentation Turner
The feces that have undergone initial dehydration need to undergo fermentation to decompose the large molecular organic matter, kill pathogens and weed seeds. The fermentation flipper can provide necessary oxygen circulation, promote microbial activity, and accelerate the fermentation process.
3. Semi Wet Material Crusher
The fermented organic matter may contain large chunks of cellulose or incompletely decomposed substances. A semi wet material crusher can further crush it into finer particles, which is beneficial for mixing and granulation.
4. Mixing Blender
In order to improve the quality and nutritional value of fertilizers, it is often necessary to mix fermented organic matter evenly with other additives such as phosphates, trace elements, etc. A mixing mixer can ensure that various ingredients are fully combined to achieve the ideal ratio.

5. Organic fertilizer pelletizing machine
The organic fertilizer granulator is responsible for making particles of a certain size and shape from the mixed raw materials, which are easy to store, transport, and use. According to specific needs, different types of equipment such as disc granulators, roller extrusion granulators, or fluidized bed granulators can be selected.
6. Cooling Dryer
The freshly granulated fertilizer still carries a certain amount of heat and moisture, which needs to be removed by a cooling dryer to prevent particle adhesion and lower the temperature to avoid loss of nutrients.
7. Screening Machine
The screening machine is used to select qualified particles, and unqualified particles will be sent back to the previous process for reprocessing to ensure the consistency of quality and specifications of the final product.
8. Packaging Machine
The final step is to measure and package the processed organic fertilizer for easy sales and use. Automated packaging machines can greatly improve production efficiency and reduce errors caused by manual intervention.
Other auxiliary equipment
In addition, a complete organic fertilizer production line may also include auxiliary facilities such as conveyor belts, elevators, dust removal systems, and control systems to ensure the smooth progress of the entire production process.
Through this organic fertilizer production line, the manure from the breeding farm can be recycled and reused, which not only solves the problem of environmental pollution but also produces high-quality organic fertilizers, achieving a win-win situation of economic and ecological benefits.
