Capacity: 5-50 m³/batch
Tank Dimensions: Length 3-15 meters, Diameter 1.5-3 meters
Fermentation Temperature: 55-75°C
Fermentation Cycle: 7-15 days (batch-type); some continuous-type equipment allows for continuous discharge
Applicable Materials: Chicken manure, cow manure, pig manure, biogas residue, mushroom residue, straw, rice husks, humus, etc.
Tank: Mostly constructed of welded stainless steel or high-strength steel plates, it offers excellent sealing and corrosion resistance, preventing odor leakage and contamination of materials during fermentation.
Agitation System: The tank is equipped with a spiral agitator or turning blades, driven by a motor, which regularly stirs the materials, ensuring adequate oxygen exposure and maintaining a uniform temperature to prevent localized anaerobic fermentation.
Control System: A heating device (such as electric heating or hot air heating) and a temperature sensor maintain the tank temperature within a range suitable for microbial activity (usually 55-75°C), accelerating material decomposition (high temperatures kill pathogens, insect eggs, and weed seeds).
Aeration System: Equipped with a fan and piping, this system introduces air into the tank, providing an aerobic environment that meets the metabolic needs of aerobic microorganisms and promotes the decomposition of organic matter.
Inlet and Outlet: The inlet is typically located at one end of the tank, where materials are transported via a conveyor belt or pump. The outlet is located at the other end. After fermentation is complete, the finished product is discharged by stirring, pushing, or tilting the tank. 6. Waste gas treatment device: Some equipment will be equipped with a deodorization system (such as a biological filter, activated carbon adsorption) to treat odorous gases such as ammonia and hydrogen sulfide generated during the fermentation process to meet environmental protection requirements.
Application Areas
1. Large-scale livestock and poultry farms: Processing pig, cattle, and chicken manure, turning waste into resources.
2. Organic fertilizer production plants: Converting straw, mushroom residue, and food waste into high-quality organic fertilizer.
3. Municipal environmental protection: Processing domestic sewage sludge and landscaping waste, reducing the need for landfill or incineration.
4. Agricultural parks: On-site processing of agricultural waste, achieving a "combined farming and breeding" approach to recycling.
After organic material enters the horizontal fermentation tank through the feed inlet, it undergoes the following processes within a closed environment:
1. Mixing and Heating: The agitation system stirs the material for uniform mixing. The temperature control system activates, raising the material temperature to above 55°C to activate aerobic microorganisms (such as actinomycetes and Bacillus).
2. Aerobic Fermentation: The aeration system continuously supplies oxygen, allowing microorganisms to decompose organic matter (such as cellulose and protein) in the material, producing carbon dioxide, water, and heat. Simultaneously, the material gradually matures, reducing the carbon-to-nitrogen ratio.
3. Maturation and Discharge: After 5-15 days of fermentation (depending on material characteristics and equipment parameters), the material reaches maturity (dark brown appearance, no odor, and neutral pH). It is then stirred and pushed to the discharge port for direct use as organic fertilizer or further processing.
Advantages of horizontal fermentation tanks:
1. High Efficiency and Speed:
Compared to traditional composting, horizontal fermentation tanks shorten the fermentation cycle to 1-2 weeks through temperature control, oxygen supply, and agitation, significantly improving processing efficiency.
2. Small Footprint:
The horizontal structure is compact, making it suitable for businesses or farms with limited space, eliminating the need for a large stockpile area.
3. Environmentally Friendly:
The sealed tank reduces odor spread and pollution caused by rainwater erosion, and the included exhaust gas treatment system further reduces environmental pressure.
4. Complete Composting:
Controllable temperature, humidity, and oxygen levels avoid problems such as incomplete composting and bacterial growth that are common with traditional composting, resulting in more stable quality of the finished organic fertilizer.
5. High Level of Automation:
The PLC control system automates processes such as feeding, agitation, temperature control, and aeration, reducing manual intervention and labor intensity

What materials are suitable for fermenting in horizontal organic fertilizer fermentation tanks?
Horizontal organic fertilizer fermentation tanks are suitable for a variety of organic waste materials, including livestock and poultry manure, crop straw, food waste, sludge, fungal residue, and medicinal residue. They are particularly suitable for processing materials with high moisture content, such as fresh manure from livestock farms and municipal sludge. The tank's internal stirring and temperature control system effectively prevents the clumping and poor air permeability problems that these materials often encounter during fermentation.
What are the advantages of horizontal fermentation tanks compared to vertical fermentation tanks?
The advantages of horizontal fermentation tanks primarily lie in uniform material handling and footprint. The horizontal structure allows the stirring device to more fully contact the material, avoiding the uneven fermentation between the upper and lower layers of the material caused by gravity in vertical tanks. Horizontal tanks are typically longer than they are high, resulting in a more compact footprint and suitable for sites with ample horizontal space. Furthermore, horizontal tanks offer easier loading and unloading, enabling continuous feeding and discharging through openings at the ends or sides, making them suitable for large-scale continuous production.
What is the typical fermentation cycle of a horizontal fermentation tank?
The fermentation cycle is affected by the material properties, tank temperature, and agitation frequency. Under ideal conditions (temperature of 55-65°C, adequate agitation, and sufficient oxygen), the fermentation cycle for livestock and poultry manure is typically 7-10 days; high-fiber materials such as straw may require 10-15 days. Compared to open-air composting (30-60 days), horizontal fermenters, due to their controlled environment, can shorten the fermentation cycle by over 50%, achieving rapid material maturity.
Is operating a horizontal fermenter difficult? Do they require specialized technicians?
Modern horizontal fermenters are often equipped with automated control systems that monitor parameters such as tank temperature, humidity, and oxygen content in real time, and automatically adjust agitation frequency, ventilation, and heating levels. Operation is relatively simple. Operators only need to perform startup, parameter setting, and routine inspections. Basic operation can be mastered after 1-2 days of training. However, equipment maintenance (such as overhauling the agitation system and calibrating sensors) may require technicians with sufficient mechanical and electrical knowledge.
What safety precautions should be taken when using a horizontal fermenter?
During operation, please note the following:
① Before adding materials, ensure that there are no hard objects such as metal or stones in the material to avoid damage to the agitator.
② During fermentation, methane and other gases may be generated in the tank. Ensure the ventilation system is functioning properly to prevent gas accumulation and explosion.
③ During maintenance, the power must be disconnected and warning signs must be displayed to prevent accidental startup.
④ During high-temperature fermentation, the tank surface temperature may be high; prevent burns.
⑤ Regularly check safety devices such as safety valves and pressure gauges to ensure they are sensitive and reliable.
What are the key points for maintenance of horizontal fermenters?
Daily maintenance needs to focus on the following:
① Agitation system: Regularly check the agitator paddles for wear, tighten the connecting bolts, and add lubricant.
② Sealing system: Check the seals at both ends of the tank for wear to prevent material leakage.
③ Electrical system: Clean the control panel, check the wiring connections, and ensure that the sensors and control system are functioning properly.
④ Ventilation system: Clean the filter to ensure smooth ventilation and avoid blockage.
⑤ Regularly treat the tank for corrosion to extend its service life.
