Main raw material of liquid biofertilizer production

What is process of the organic liquid biofertilizer production technology?

Organic liquid biofertilizer production technology adopts anaerobic fermentation and has strict requirements on the production process. The following is the liquid organic biofertilizer production process:

The first step in bio liquid organic fertilizer manufacturing process is animal manure solid liquid separation. There are two ways to get liquid animal manure material. If you want to start organic biofertilizer liquid production quickly, you can use an animal manure dehydrator to separate liquid from solid manure. If you want to save the cost of manure solidliquid separation, constructing an animal manure sedimentation tank is a good choice.

For improving the quality of liquid organic biofertilizer, you should use a filter device to remove impurities after the dehydration process. Then, you will get the acquire pure animal manure liquid. YUSHUNXIN’s double filtration system can accurately filter impurities and particles of 38-250μm.

After filtering out impurities, in order to obtain safe liquid biofertilizer, you need to use a disinfection device to kill bacteria, pests and diseases in the manure liquid. YUSHUNXIN has installed two UV sterilizers on the liquid biological organic fertilizer production line, achieving a 99% sterilization rate.

After sterilization, using anaerobic fermentation tank to chelate and ferment the manure liquid into liquid organic fertilizer. The fermentation cycle typically lasts about 3 – 5 days. During this fermentation process, you can add some microorganism agents, such as lactic acid bacteria, phosphate-solubilizing bacteria, and potassium-solubilizing bacteria.

Packaging is the last step of bio organic liquid fertilizer production. There are the semi-automatic, automatic liquid biofertilizer filling machines in YUSHUNXIN.It integrates filling and labeling in one, with complete functions. Whether you want to bottle fertilizer in 500ml-5L bottles for small-scale sales, or pack it in 5L-200L barrels for large-scale distribution, our machines can meet your needs.

How to make liquid npk biofertilizer?

  • To produce NPK liquid biofertilizer, you should prepare the N,P,K material in advance.

  • Then, the dynamic batching machine will put them accurately according to the bio NPK liquid fertilizer formulations.

  • Next, Add water and biological agents to the mixture and let them react in a liquid chelating tank.

  • After the reaction, you can filter the liquid to get pure npk liquid biofertilizer.

  • Finally, package it into various sizes with a fullyautomatic filling machine for sale.

Effective Solutions for Using Tap Water in Liquid Biofertilizer Production

Tap water can be used as a base water source for liquid biofertilizer production, making it a convenient and cost-effective option. However, to ensure product quality, it is essential to treat the tap water before use. Untreated water may contain salts, heavy metals, or organic contaminants that can reduce the effectiveness of microbial agents or lead to product instability. YUSHUNXIN recommend using a reverse osmosis (RO) water purification system which can effectively removes harmful substances and improves the consistency of your final liquid biofertilizer.

YUSHUNXIN can provide RO systems based on your plant capacity.

  • Small-scale RO systems (1–50 m³/h)

  • Integrated ultrafiltration systems (10–100 t/h) for larger operations

Once purified, you can add bioformulas, NPK powders, trace elements, and cosolvents as needed. Mix these ingredients in a chelating tank for 1–2 hours before filling the final liquid biofertilizer.

Can you provide fish residue liquid biofertilizer production technology?

Of course. Among various liquid biofertilizer production technologies, producing fertilizer from fish residue begins with a critical step—grinding the raw material into fine particles. It can speed up the enzymatic reaction. At the same time, it can also ensure that the fish residue and other additives (such as microbial agents, trace elements, etc.) are evenly mixed. For this, we designed the double-shaft grinder. The double-shaft grinder uses two relatively rotating knife rollers to tear, shear and squeeze the fish residue with blades. It can quickly and effectively break the fish residue into small particles to meet the needs of producing fish protein biological liquid fertilizer.

Next, add an appropriate amount of water to the crushed fish residue. Then steam sterilize, cool, chelate, filter and fill the final fish residue liquid biofertilizer. It’ necessary to add microbial agent in chelation tanks for improving liquid bio fertilizer efficiency.

what is the cost of establishing a liquid bio fertilizer plant?

The cost of setting up a liquid biofertilizer production factory depends on your daily capacity, equipment complexity, and automation level. Below is a breakdown by production scale:

Estimated Cost: $40,000–$70,000

This setup is ideal for farms, agri-cooperatives, or startups aiming to process small batches of organic liquid fertilizer. It typically includes: 5–10m³ anaerobic fermentation tank, basic pre-treatment: filtering, pH adjustment, manual or semi-auto mixing and filling machine.

Compatible with raw materials like cow urine, EM waste, or fish residue

Estimated Cost: $120,000–$250,000

We designed the bio liquid fertilizer unit for regional biofertilizer suppliers and medium-sized farms. Its configuration include: 15–30m³ fermentation tanks with temperature & pH monitoring, inline dosing systems for microbial strains (e.g., Bacillus subtilis, EM), two-stage filtration to remove impurities and enhance product clarity, semi-automatic filling line (1–20L bottle compatible).

Estimated Cost: $450,000–$750,000+

Built for commercial fertilizer manufacturers and agro-industrial zones. Features include: automated PLC-controlled fermentation system with 50m³+ tank, sterilization units (UV or low-temp) to stabilize microbial activity, automated CIP cleaning system to reduce contamination risks, integrated packaging line with multi-head fillers, bottle cappers, and labelers

How to add microbial agents in liquid biofertilizer production technology?

Generally, the commonly used agents in bio liquid fertilizer production are potassium-dissolving bacteria, streptomyces, organic matter-decomposing bacteria, etc. You can use the small batching tank for adding them before chelation. YUSHUNXIN’s small batching tanks use high-quality stainless steel, such as SUS304 and SUS316, good corrosion resistance. And they have insulation layers and stirring devices.This can effectively blend the microbial agent with water and transfer them into chelation tank.
