liquid organic fertilizer manufacturing process

The liquid organic fertilizer manufacturing process generally includes four main stages: solid-liquid separation, fermentação, filtration and sterilization, and final filling. Each stage plays an important role in ensuring nutrient stability, safety, and product quality. Em YUSHUNXIN, we supply complete sets of equipment for every stage, such as solid-liquid separators, stainless steel anaerobic fermentation tanks, dual-stage filtration systems with backwash function, UV sterilizers, additive mixing tanks, and precise filling machines. Whether you need a small-scale unit or a fully automated production line, we can design a solution based on your raw materials, additives, and capacity needs. Contact us to discuss your liquid organic fertilizer production project today.

The main equipment for the production of organic liquid fertilizer:

Liquid organic fertilizer production equipment varies according to raw materials and output. The following are the specific configurations:

Solid-Liquid Separator:O solid-liquid dehydrator extracts the liquid fraction from organic waste for further processing into liquid fertilizer. You can choose from inclined screen, screw press, or multi-plate screw press. According to different dewatering methods, these machines can separate solids while keeping nutrient-rich liquid intact. This ensures you get clean, pumpable liquid that's ready for fermentation.
Duplex Filter System: To produce high-quality liquid organic fertilizer, you need a clean raw liquid. we recommend the duplex filter, which completes two-stage filtration. The first chamber removes larger particles. The second chamber removes fine impurities down to 50–100 microns. Meanwhile, its automatic backwashing system keeps filtration stable and reduces manual cleaning.
UV Ultraviolet Sterilizer: Even after filtration, raw liquid still contains harmful bacteria and pathogens. A UV sterilizer disinfects the liquid as it flows through the chamber. It destroys DNA structures of bacteria and viruses without heating or affecting nutrient content. The sterilization rate reaches 99.9%, which ensures safe and stable liquid organic fertilizer.
Anaerobic Fermentation Tank: The fermentation tank is the core unit in an organic liquid fertilizer production line. Our tanks use 304 aço inoxidável, providing corrosion resistance and long service life. Inside the tank, you get: a stirrer for even mixing, a defoaming system, thermal insulation to maintain temperature, and optional steam or electric heating for faster fermentation.
Ingredient Mixing Tank: If you need to add microorganisms, NPK nutrients, humic acid, amino acids, or trace elements, the auxiliary mixing tank ensures accurate dosing. Ao mesmo tempo, its high-speed agitator creates uniform blending and prevents sedimentation, improving the stability of the final formula.
Automatic Liquid Fertilizer Filling Machine: O liquid filling system packs liquid fertilizer into 5 eu, 20 eu, 25 eu, 50 L or customized containers. You can adjust the volume easily. The machine offers high accuracy (±0.2%) and keeps production clean, fast, and consistent.

The specific configuration depends on your production capacity. Contact us to discuss the commercial production plan for liquid organic fertilizer!

How to produce organic liquid fertilizer?

Primeiro, seperate the liquid from solid. Então, you can set a sedimentation tank to store liquid raw materials. Próximo, the liquid passes through two automatic cleaning filters to remove large impurities. Então, the filtered liquid undergoes UV sterilization twice to kill harmful bacteria and pathogens. After sterilization, the clean liquid moves into the ingredient tank, where you add necessary nutrients and additives. It then enters the anaerobic fermentation tank intergrating mixing, heating. After 3 dias, fermentation process is over. Próximo, the liquid transfers to the second boiling pot. At this stage, you add water-soluble humic acid and NPK elements to enhance nutrient content. Afterward, the finished product goes into a storage tank for buffering and quality stabilization. Finalmente, the automatic filling machine fills the liquid fertilizer into containers, ready for distribution.

What raw material are used in liquid organic fertilizer manufacturing?

As long as the raw material contains organic matter and nutrients, YUSHUNXIN liquid fertilizer equipment can turn it into high-value liquid fertilizer through separation, filtração, and fermentation.

You can use a wide range of organic materials to produce liquid organic fertilizer. These materials come from livestock farms, crop processing plants, fish processing lines, and biogas systems.: Livestock and Poultry Manure
Livestock manure is the most widely used raw material for liquid organic fertilizer. Cow dung, pig manure, chicken poop, and sheep manure all contain rich organic matter and soluble nutrients. You can use a solid-liquid separator to remove the fibers and sand, and the separated liquid becomes the main fermentation base.

Fish Waste and Slaughterhouse By-products
Fish processing waste, fish meal, and animal by-products are excellent sources for fish protein liquid fertilizer. Before fermentation, you need to crush and pre-treat them to remove large bones or impurities.

Biogas Slurry, Manure Wastewater, and Compost Extract
Biogas slurry, manure wastewater, and compost extract offer the most economical route for liquid organic fertilizer production. Its processing time is short and the investment is low. You only need to pump the liquid through a filtration unit, remove suspended solids, and send it into a UV sterilizer to stabilize the microbial count.

What addtives can be added to liquid organic fertilizer manufacturing process ?

We provide auxiliary additive tanks for precise dosing of nutrients and functional additives. This ensures stable liquid fertilizer formulations and improves production efficiency. Bem-vindo ao consultar!

Nutrient Elements

During liquid organic fertilizer manufacturing process, you can add not only nitrogen, phosphorus, e potassium but also essential trace elements. This precise formulation improves nutrient balance and significantly enhances the quality of liquid organic fertilizer.
Bio-inoculants

Adding composite bacillus, lactic acid bacteria, and other beneficial microbes accelerates organic matter breakdown and promotes uniform fermentation. Each kilogram of microbial inoculant can ferment 500–1000 kilograms of liquid organic fertilizer, enhancing biological activity and overall product quality.
Functional Additives

Suspension agents and stabilizers, such as xanthan gum, guar gum, and bentonite clay, prevent solid particles from settling, keeping the liquid fertilizer evenly mixed. This improves storage stability, reduces sedimentation during transport, and helps maintain product quality throughout distribution.

How much does the organic liquid fertilizer production plant cost?

The cost of a liquid fertilizer production line usually ranges from $10,000 para $400,000, depending on capacity and equipment configuration. Por exemplo, building a 5,000 L/H organic liquid fertilizer processing plant typically costs at least $60,000. A 10,000 L/H liquid organic fertilizer production line is priced around $150,000. Se você precisar, YUSHUNXIN can provide a more economic commercial liquid fertilizer business solutions. This includes a filtration and UV sterilization unit, um 5 m³ fermentation tank, and a filling machine (or manual filling option). The total cost starts from $8,000. Contact us now!
