YUSHUNXIN’s biofertilizer fermenters handle a wide range of organic waste. This makes them ideal for farms, biogas facilities, waste recycling stations, and composting projects. With high-temperature aerobic fermentation, the tank breaks down organic matter quickly and safely. Whether you’re composting manure or converting industrial waste, this tank ensures safe, efficient fermentation.

You can feed the fermenter with:

  • Animal manure – chicken, cow, pig, sheep, etc.

  • Crop residues – straw, corn stalks, rice husks, peanut shells
  • Biogas residue and digestate – from anaerobic digestion systems

  • Municipal organic waste – kitchen leftovers, treated sludge
  • Organic industrial waste – brewery sludge, fruit and vegetable scraps
Fermentation Tank for Quick Compost

Each raw material ferments under controlled temperature, moisture, and oxygen levels. This compatibility helps you maximize resource use while meeting strict environmental standards. With flexible design and various capacities (5-150m³), it’s a one-stop solution for turning organic waste into valuable biofertilizer.

What is the structure of the fermenter for biofertilizer production?

The fermenter for biofertilizer production usually consist of the following main parts:

The main structure of the fermenter, usually a cylindrical or square design. Our bio-fertilizer fermenters are made of high-strength carbon steel or 304 stainless steel with thermal insulation to maintain stable fermentation temperature.

Inside the fermenter, we design a horizontal or vertical agitator shaft with multiple paddles continuously stirs the material. It not only helps regulate moisture and temperature, but ensures microbial inoculants are evenly incorporated. The agitator is powered by a durable motor and gearbox, selected according to the capacity and viscosity of the composting material.

We have set up an integrated temperature monitoring system. It can track the various stages of composting (medium temperature, high temperature, cooling) in real time. The system can automatically adjust aeration or agitation to maintain ideal fermentation temperatures (55–70°C), ensuring effective pathogen elimination and microbial activity.

To meet environmental standards and prevent odor leakage, the fermenter is equipped with an exhaust gas collection system connected to a biofilter, activated carbon unit, or water spray scrubber. This system filters harmful gases like ammonia and hydrogen sulfide before discharging them, ensuring compliance with emission regulations.

Efficient fermentation depends on adequate oxygen. The fermentation pot includes a forced aeration system, using blowers and aeration pipes to inject oxygen directly into the material bed. It can effectively optimize microbial metabolism and reducing composting time.

Once fermentation is complete (typically 7–10 days), the fermented material is discharged via a hydraulic or screw outlet system at the bottom.At the same time, we equiped the fermentation tank with access ports or ladders for cleaning, inspection, and maintenance—facilitating safe, long-term operation.

What Types of Biofertilizer Fermenters Does YUSHUNXIN Offer?

YUSHUNXIN offers three main types of biological fertilizer fermenters to meet different composting needs:

The horizontal fermenter

It is an ideal choice for rapid aerobic composting. The horizontal fermenter features automatic mixing and temperature control, ensuring even fermentation and efficient odor control. It is suitable for small to medium-scale farms.

The horizontal fermenter

Horizontal Fermentation Tanks 

horizontal fermentation cylinder
Model SXWFT
Motor Power (KW) 18.5
Heating Rod Power (KW) 3*10
Hot Oil Pump Power (KW) 1.5
Inlet Hydraulic Power Unit Power (KW) 0.55
utlet Hydraulic Power Unit Power (KW) 0.55

The vertical fermentation pot

Space-saving and fully enclosed. This fermenter handles larger volumes and maintains consistently high temperatures. It can dispose of 5-150 m³ of organic waste. It’s perfect for commercial biofertilizer production with limited land area.

Organic Vertical Fermentation Pot

Model Heating Power (KW) Stirring Power (KW) Feeding type Dimensions(mm)
SXFT-10 4 11 Conveyor 2400x2400x6900
SXFT-20 4 18.5 Conveyor 3100x3100x6500
SXFT-30 4 7.5 Bucket 4000x4000x7000
SXFT-100 4 7.5 Bucket 5000x5000x8500

Anaerobic Fermentation Tank

If you want to handle high-moisture organic materials, the anaerobic fermenter is a good choice. In a sealed oxygen-free environment, these tanks not only generate biogas for energy use, but also reduce odors and harmful pathogens during fermentation. This makes anaerobic fermentation a cost-effective and eco-friendly solution for waste treatment.

What should you pay attention to when using fermenter for biofertilizer production?

Digestate

Keep Fermentation Conditions Stable and Controlled

You should set the temperature between 50-75°C, and check pH and moisture daily. Use proper aeration for aerobic strains or seal the tank for anaerobic ones. Stable conditions help microbes grow fast and produce high-quality fertilizer. Avoid sudden changes that could harm the fermentation process.

Choose the Right Fermenter Design for Efficient Production

It is benefical for you to pick a fermenter with automatic mixing, thermal insulation, and a sealed or ventilated top. Stainless steel tanks resist corrosion and clean easily. Good design improves fermentation speed, saves energy, and reduces manual labor. Match the fermenter to your material type and production scale. If you are not sure, welcome to consult YUSHUNXIN !

Clean Regularly and Select the Right Microbial Strains

Rinse and disinfect the tank after every use. This prevents contamination. Choose strains based on your soil, climate, and crops. Use proven options like Bacillus or Trichoderma. Custom blends work better if you target specific plant needs or market demands.

Top 4 Cost-Saving Benefits of Using Biological fertilizer Fermentation Tanks

Choosing the right fermenter can save you more than just time—it can dramatically cut labor, land, and environmental expenses. Here’s how a modern fermentation tank helps you maximize profits while minimizing biofertilizer plant  costs.

Biofertilizer fermenters reduce energy and labor expenses with automated temperature and mixing systems. Unlike traditional composting, they eliminate the need for frequent manual turning, saving you daily labor costs and fuel consumption.

Closed fermenters complete composting in 7–15 days, compared to 30–60 days with traditional methods. Moreover, it is not affected by external weather and temperature. Faster turnover means quicker sales of finished biofertilizer and a faster return on your investment.

Vertical or horizontal fermentation tanks take up far less space than open composting areas. This allows you to set up a biofertilizer production line even on a small plot, reducing land leasing or construction costs.

Sealed fermenters control odor and leachate, helping you comply with environmental regulations without investing in expensive treatment systems. This reduces the risk of fines or shutdowns due to pollution complaints.
