Cow Dung Liquid Fertilizer Production

Cow dung liquid fertilizer production is an efficient way to recycle manure and turn it into high-value agricultural products. The process includes six main steps: solid-liquid separation, impurity filtration, UV sterilization, anaerobic fermentation, nutrient adjustment, and final liquid fertilizer filling. Alongside liquid fertilizer making, producers can compost, crush, screen, and pelletize the separated solids to create solid cow dung fertilizer. YUSHUNXIN provides complete solutions for both liquid and solid cow dung fertilizer production, helping you maximize resource use and improve output efficiency.

What are the main process of making liquid fertilizer from cow manure?

Cow Dung Liquid Separation:The first step is to separate the liquid from the solid cow manure. You can use the cow dung dewatering machine. It works efficiently to extract the cattle wastewater. Entonces, you can reuse the dewatered solids to make compost or organic fertilizer. It is the best choice to build a sedimentation tank to collect the separated liquid.
Filter Liquid Cow Manure Impurities: There are some impurities in the liquid cow manure. Entonces, you can use a duplex filter system for removing them from the liquid manure. In the first stage, an automatic filter with quartz sand removes larger particles. Entonces, pumps transfer the liquid to the second filter, where activated carbon eliminates fine impurities and improves liquid clarity.
UV Liquid Fertilizer Sterilization: After filtration, sterilization is essential for ensuring the safety of cow dung liquid fertilizer. A UV sterilizer uses ultraviolet light to quickly perform primary and secondary disinfection. This step kills harmful pathogens, poisonous bacteria, and insect eggs.
Fermentation of Liquid Cow Dung Fertilizer: Once disinfected, the cow dung liquid is transferred to the anaerobic fermentation tank for processing. You can enhance the fermentation process by adding liquid fermentation bacteria or molasses, which provide energy for rapid fermentation. The entire fermentation cycle is completed within three days.
Secondary Chelating Tank: After fermentation, you can add NPK powders, aminoácidos, or beneficial microorganisms to produce formula cattle manure liquid fertilizer. We can offer the additive adding tank for you.Chelation ensures that nutrients stay available and stable in the final product.
Cow Dung Liquid Fertilizer Filling: Finalmente, transfer the finished liquid fertilizer into a storage tank. Entonces, fill it into bottles, barrels, or bulk containers according to your market needs. A good liquid filling system guarantees accurate volumes and clean packaging, ready for delivery.

By following these steps, you can set up an efficient and profitable cow dung liquid fertilizer production line.

The methods of anaerobic fermentation of cow manure liquid fertilizer production

Anaerobic fermentation technology is the core process in liquid cow manure fertilizer production. Durante la fermentación, microorganisms decompose organic matter in cow dung liquid under oxygen-free conditions. This process converts unstable organic compounds into stable liquid fertilizer, and reduces harmful bacteria and odors. YUSHUNXIN offers high-efficiency tanques de fermentación anaeróbica for this process. Each anaerobic fermenation pot has an internal stirring system to keep the liquid evenly mixed, a built-in filter to remove residue, and an insulation layer to maintain optimal temperature. These features keep fermentation time in 72 h. During anaerobic fermentation of cow manure liquid, microorganisms require sufficient energy and trace nutrients. Therefore, you can add carbon sources such as molasses, azúcar moreno, or glucose to promote microbial activity. Among these options, molasses is the most economical choice for liquid fertilizer producers, with a recommended addition rate of 4%–5%. It is benefical to helping shorten fermentation time and improve fertilizer quality.

How to Improve Stability and Storage Life in Cow Dung Liquid Fertilizer Production?

In cow dung liquid fertilizer manufacturing process, poor stability can lead to sedimentation, pérdida de nutrientes, and spoilage.

To keep your liquid manure fresh and effective for longer, you need the right processing steps and equipment. we offers complete solutions to improve stability and extend shelf life.: Multi-stage processing
Our system uses multi-stage filtration to remove suspended solids, followed by UV sterilization to kill harmful bacteria and prevent unwanted fermentation.

Add chelating agent
In the chelation tank, puedes agregar estabilizadores, chelating agents, and pH regulators to prevent nutrient precipitation. For better nutrient retention, we recommend adding natural stabilizers (Molasses, Guar gum, Citric acid etc.) during processing.

High-qualiy equipment support
YUSHUNXIN liquid fertilizer production machine adopts sealed structure and anti-corrosion lining to ensure the production of cow dung liquid fertilizer to the greatest extent.

¿Cuánto tiempo se tarda en hacer fertilizante líquido?

En most liquid fertilizer production processes, the complete cycle takes about 3–5 days from raw material preparation to storage. El tiempo de fermentación depende de la temperatura., equilibrio de nutrientes, and microbial activity. Puede ajustar estos factores para optimizar la producción de fertilizantes líquidos.

Adding Microbial Fermentation Agents

En liquid fertilizer fermentation, el inoculante microbiano juega un papel decisivo en la descomposición de la materia orgánica y la transformación de nutrientes. Entonces puede agregar algún agente beneficioso para acelerar el proceso de fabricación de fertilizantes líquidos.. Como el compuesto Bacillus, levadura compuesta, compound lactic acid bacteria, y preparaciones enzimáticas compuestas. Típicamente, 1 kg de agente microbiano pueden fermentar entre 250 y 500 litros de fertilizante líquido. La dosis específica depende de la composición de su materia prima., velocidad de fermentación deseada, y requerimientos de nutrientes.

How to Use Solid By-products from Cow Dung Liquid Fertilizer Production for Pellets?

To maximize the value of cow dung, you can turn the residues from solid-liquid separation into high-quality solid cow dung fertilizer.

Primero, compost the separated cow dung solids. This step reduces pathogens and stabilizes nutrients.
Then use a compost crusher to break the material into fine particles. Próximo, screen it to remove large impurities, such as small stones or cigarette butts.

For higher profits in cow dung fertilizer manufacturing, it is an excellent choice for you to granulate the powdered compost. YUSHUNXIN offers various cow dung pelletizing machines, including disc granulators, roller extrusion compactors, and new organic fertilizer pelletizers. Finalmente, feed the pellets into an automatic packaging machine for efficient storage and sale.
