Straw fermentation tankAs an efficient and environmentally friendly agricultural waste treatment equipment, its advantages are reflected in multiple aspects such as technical efficiency, resource utilization, environmental friendliness, and operational management.
Straw fermentation tankCore advantages:
1、 High fermentation efficiency and short cycle
Accelerate microbial metabolism
By precisely controlling the temperature (50-65 ℃), humidity (50% -65%), and oxygen supply (forced ventilation or stirring), the optimal growth environment is created for microorganisms, significantly improving their ability to decompose difficult to degrade substances such as cellulose and lignin in straw.
Shorten the fermentation cycle
Traditional composting takes more than 30 days, while fermentation tanks can shorten the cycle to 7-15 days and increase efficiency by more than 50% through mechanical stirring and dynamic environmental regulation.
Uniform maturity
The mixing system (such as spiral blades or paddles) ensures thorough mixing of materials, avoids local anaerobic or nutrient loss, and produces organic fertilizer with consistent maturity.
2、 High resource utilization rate and increased product value
Optimization of Organic Fertilizer Quality
During the fermentation process, nutrients such as nitrogen, phosphorus, and potassium in straw are converted by microorganisms into forms that plants can directly absorb, while increasing organic matter content (up to 30% -50%) and improving fertilizer efficiency.
Clean energy production (anaerobic mode)
If anaerobic fermentation is used, biogas (with a methane content of 60% -70%) can be produced simultaneously for power generation, heating, or as a biofuel, achieving energy recovery.
Comprehensive utilization of by-products
Biogas residue can be further processed into granular fertilizer or soil amendments, while biogas slurry can be used as liquid fertilizer or irrigation water, forming a closed loop of "straw fertilizer/energy planting".
3、 Outstanding environmental performance and effective pollution control
Sealed design reduces emissions
The fermentation tank adopts a fully enclosed structure, effectively blocking the diffusion of odors (such as ammonia and hydrogen sulfide) and greenhouse gases (such as methane), reducing the risk of air pollution.
Exhaust gas treatment system
Equipped with biological filters or chemical absorption devices to purify the emitted gases and ensure compliance with emission standards.
Harmless treatment of pathogenic bacteria
High temperature fermentation (above 55 ℃ for 3-5 days) can kill weed seeds, insect eggs, and pathogens in straw, reducing the need for pesticide use.
4、 Strong adaptability and wide processing range
High compatibility of raw materials
Can handle high moisture materials (such as livestock manure with a moisture content of 60% -70%), adjust the carbon nitrogen ratio (C/N) by adding auxiliary materials such as straw and sawdust, and optimize fermentation conditions.
Multi mode flexible switching
Aerobic mode: suitable for straw pretreatment and rapid composting of livestock and poultry manure.
Anaerobic mode: suitable for the energy utilization of high concentration organic waste such as kitchen waste and municipal sludge.
Dual mode combination: By dynamically adjusting environmental parameters, a collaborative process of "aerobic pretreatment+anaerobic gas production" is achieved.
Scalable scale
From small family style fermentation tanks (processing capacity of 1-5 tons/batch) to large-scale industrial equipment (processing capacity of 50-200 tons/batch), meet the needs of different scenarios.
5、 Easy to operate, low management cost
Automated control system
Integrated temperature, humidity, and oxygen concentration sensors, real-time monitoring and automatic adjustment of ventilation, mixing, and heating parameters, reducing manual intervention.
modular design
The device has a compact structure, easy installation and maintenance, supports remote monitoring and fault diagnosis, and reduces operation and maintenance costs.
compact footprint
Horizontal or vertical tank design, with a unit processing capacity occupying only 1/5-1/10 of the traditional composting site, suitable for areas with scarce land resources.
6、 Significant economic and social benefits
Reduce agricultural costs
On site fermentation of straw for fertilizer production reduces the cost of purchasing and transporting fertilizers, while avoiding the risk of fines for straw burning.
Policy support and subsidies
In line with national policies such as "comprehensive utilization of straw" and "carbon peak and carbon neutrality", environmental protection project subsidies or tax incentives can be applied for.
Promote circular agriculture
By utilizing straw as a resource, reducing agricultural waste pollution, promoting ecological planting and sustainable development.
