Sản xuất phân bón lỏng Dung Dung

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?

Nhận giải pháp

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. Sau đó, 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. Vì thế, 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. Sau đó, 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, amino acids, 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: Cuối cùng, transfer the finished liquid fertilizer into a storage tank. Sau đó, 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. During fermentation, 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 bể lên men kỵ khí 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. Vì thế, you can add carbon sources such as molasses, brown sugar, 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, nutrient loss, 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, you can add stabilizers, 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.

How long does it take to make liquid fertilizer?

TRONG most liquid fertilizer production processes, the complete cycle takes about 3–5 days from raw material preparation to storage. Fermentation time depends on temperature, nutrient balance, and microbial activity. You can fine-tune these factors to optimize liquid fertilizer production.

Adding Microbial Fermentation Agents

TRONG liquid fertilizer fermentation, the microbial inoculant plays a decisive role in organic matter decomposition and nutrient transformation. So you can add some beneficial agent to accelerate liquid fertilizer manufacturing process. Such as compound Bacillus, compound yeast, compound lactic acid bacteria, and compound enzyme preparations. Tiêu biểu, 1 kg of microbial agent can ferment 250–500 liters of liquid fertilizer. The specific dosage depends on your raw material composition, desired fermentation speed, and nutrient requirements.

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.

Đầu tiên, 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. Next, 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. Cuối cùng, feed the pellets into an automatic packaging machine for efficient storage and sale.
