liquid fertilizer anaerobic fermentation process

Liquid fertilizer anaerobic fermentation process is an efficient method to convert organic waste into nutrient-rich liquid organic fertilizer. Using raw materials such as animal manure, poultry litter, tàn dư cây trồng, and biogas slurry, you can produce liquid fertilizer with stable nitrogen, phosphorus, and potassium content. YUSHUNXIN provides professional anaerobic fermentation systems, including solid-liquid separation equipment, UV sterilizers, and anaerobic fermentation tanks. These systems help you achieve fast fermentation cycles, ensure consistent nutrient levels, and reduce production risks.

What are the Key Equipment for Efficient Anaerobic Fermentation?

To achieve a high-quality liquid fertilizer anaerobic fermentation process, it is an excellent choice for you to use the following machines.

Solid-Liquid Separator: các liquid-solid separator removes solid particles from raw manure, tàn dư cây trồng, or biowaste. By eliminating excess solids, you obtain liquid waste ready for liquid fertilizer preparation. This step ensures that the feedstock entering fermentation is uniform, nutrient-rich, and free from clogging. Efficient separation also reduces downstream maintenance and accelerates anaerobic digestion, improving overall liquid fertilizer production efficiency.
Disinfection System (UV or Heat Sterilization): The disinfection system is crucial in the liquid fertilizer anaerobic fermentation technology. It eliminates harmful microorganisms, stabilizes the liquid fertilizer, and ensures that beneficial microbes dominate. This accelerates organic matter breakdown, prevents odor, and helps maintain consistent NPK levels in the final product.
Anaerobic Fermentation Tank: The anaerobic fermentation pot is the core of the liquid organic fertilizer production line. It provides a controlled, oxygen-free environment where microorganisms convert organic matter into nutrient-rich liquid fertilizer. YUSHUNXIN’s tanks feature intelligent temperature control, automatic agitation, and anti-foaming systems. They maintain optimal temperature and pH for microbial activity, completing the process within 3–5 days.

All equipment is made of high-quality stainless steel and features built-in CPI cleaning functions, resisting corrosion from liquid fertilizers.

The working principle of anaerobic fermentation technology in liquid fertilizer making:

Anaerobic fermentation transforms organic matter into nutrient-rich liquid fertilizer through the metabolic activity of anaerobic microorganisms. In an oxygen-free environment, these microbes decompose proteins, carbohydrates, and lignin into soluble nitrogen, phosphorus, and potassium. The fermentation process typically completes in 3–5 days under mesophilic conditions (35–40°C), when microbial enzymatic activity is optimal. During fermentation, producers can introduce supplemental NPK powders, trace elements, or microbial inoculants to enhance nutrient content and biological activity. The recommended addition is 1–5% of total feedstock, ensuring uniform distribution without inhibiting microbial metabolism. Maintaining stable pH and nutrient balance allows microbes to efficiently convert complex compounds, stabilize the liquid fertilizer, and reduce odor.

How to Avoid Mistakes in Anaerobic Fermentation for High-Quality Liquid Fertilizer

By following these below steps, you can maximize efficiency, ensure stable NPK content, and produce top-quality liquid fertilizer.

Temperature Fluctuations

Problem: Sudden drops or spikes slow microbial activity, reducing nutrient conversion.
Solution: Maintain stable 35–55℃ using controlled heating; monitor daily to ensure consistent fermentation and NPK levels.
Oxygen Contamination

Problem: Air entering the tank causes aerobic microbes to dominate, slowing anaerobic digestion.
Solution: Keep tanks sealed and check gaskets; use YUSHUNXIN’s anti-foaming and oxygen-proof designs to ensure true anaerobic conditions.
Incorrect Nutrient or Microbe Addition

Problem: Over- or under-dosing microbial agents or trace elements can inhibit fermentation or produce unstable fertilizer.
Solution: Add 1–5% inoculants and nutrients precisely; follow preset ratios to maintain uniform, high-quality liquid fertilizer.

What are the common Raw Materials for Liquid Fertilizer Anaerobic Fermentation?

The liquid fertilizer anaerobic fermentation process plays a vital role in converting organic waste into stable and nutrient-rich liquid fertilizer. Common raw materials include animal manure, biogas slurry, crop residue extracts, and food processing wastewater. These liquids carry soluble N, P, and K, essential for high-quality fertilizer. Anaerobic fermentation effectively decomposes organic matter in these raw materials, neutralizes pathogens and odors, and stabilizes their nutritional content.
