What is Fish Fertilizer

Fish fertilizers are agricultural fertilizers made from marine or freshwater fish through microbial fermentation, biocatalysis or chemical catalysis. Depending on the production process, fish fertilizers can be divided into various types such as enzymatic fish fertilizers, bacterial fish fertilizers and hydrolyzed fish fertilizers. These fertilizers are rich in nutrients such as organic matter, amino acids, vitamins and trace elements, and have a significant effect on plant growth.

Fish Fertilizer Production Process

Raw material shredding:
Select suitable fish or processing waste as raw materials, use shredder equipment to crush raw materials into suitable size particles for subsequent processing.

Low-temperature bacteriolysis: Under controlled temperature, humidity and aeration conditions, specific microbial strains are utilized for fermentation to break down proteins into small molecules such as amino acids and peptides.

Refining: Solid-liquid separation of the fermented mixture and collection of the liquid fertilizer. The liquid fertilizer continues to be filtered to remove impurities and incompletely decomposed material, and is concentrated or diluted if necessary.

Role of shredder in fish fertilizer production process

Crushing Function： Through its powerful crushing ability, the shredder crushes organic waste such as raw fish into fine particles or fragments.
The increased surface area of the crushed fish is conducive to the attachment and propagation of microorganisms, thus accelerating the decomposition and transformation process of organic materials. This not only shortens the fermentation or composting cycle, but also improves the quality and stability of the final product.

Screening function: The shredder is designed to incorporate a screening function that removes impurities and substances that are not easily decomposed from the raw material during the crushing process. This helps to reduce the difficulty and cost of subsequent processing, while improving the purity and safety of fish fertilizer.

Improved fertilizer quality: Through the shredder process, raw fish is refined into easily decomposable particles, speeding up the fermentation or composting process. This results in a final fish fertilizer of higher quality and richer in nutrients. High-quality fish fertilizer can better meet the growth needs of crops and improve crop yield and quality.
