On the track of harmless and resourceful treatment of manure waste, more and more manufacturers are promoting the slogan of “energy-saving fermentation tanks.”
However, true energy efficiency is never about “the lower the number, the better.” Instead, it depends on whether energy consumption is proportional to output and whether the system is stable and reliable.
Today, we will conduct a detailed comparison between Bolong high-temperature aerobic fermentation tank and another brand’s fermentation tank to see what “true energy efficiency” really means.
Bolong vertical fermentation tanks employ a fully hydraulic drive system, comprising both hydraulic feeding and hydraulic discharging. This design maintains stable pushing force under high-intensity working conditions, with high energy transfer efficiency and virtually no electrical energy waste.
In contrast, a certain company uses hydraulic systems only at the discharging end, while still relying on electric motors for feeding. This approach leads to instant current surges during high-resistance feeding, resulting in greater electrical energy loss and increased risk of equipment failure.
The aeration blower is the most energy-consuming component in the fermentation tank, accounting for over 60% of the total energy consumption.
Bolong employs direct-drive fans (11kW power) that provide uniform and ample air supply, featuring mature technology and stable operation. These fans boast a long lifespan, are resistant to water ingress, and maintain consistent air pressure over time, ensuring more thorough material fermentation and higher energy efficiency.
In comparison, a certain brand uses a variable-frequency fan. Although marketed as “energy-saving,” in actual operation, if the resistance inside the tank increases, it can cause a sudden spike in instantaneous power consumption, leading to an overall rise in energy usage. Additionally, the ceramic components inside its fan have a short lifespan of only about two years, requiring frequent replacements, which not only increases maintenance costs but also disrupts the continuity of fermentation.
Bolong vertical fermentation tanks are equipped with intelligent electrical control system that can monitor the agitator arm’s current in real-time. When the agitator arm encounters significant resistance, the system automatically reduces the current; when resistance is low, the current increases automatically, achieving dual functions of dynamic energy savings and equipment protection.
This intelligent adjustment mechanism ensures that Bolong equipment maintains energy-efficient operation even under high-intensity workloads, eliminating unnecessary “power wastage.”
Taking a 160m³ fermentation tank as an example:
One brand advertises an energy consumption of 450 kWh/day, while Bolong’s is 600 kWh/day.
At first glance, it might seem that the other brand is more energy-efficient. However, when we look at processing capacity, the opposite is true.
Due to unstable fan output, a certain brand’s daily feed volume can only maintain 8 hoppers; whereas Bolong, with its stable airflow and intelligent control, can continuously process 10–12 hoppers, achieving a 1.5 times higher daily processing capacity under the same volume.
Bolong is also equipped with an independent heat exchange system that recovers heat from exhaust gases to warm the fresh air entering the tank.
This design not only effectively reduces electricity consumption for heating but also makes the fermentation process more energy-efficient and productive.
Within the same fermentation cycle, Bolong equipment achieves more thorough fermentation with lower energy consumption, truly combining energy savings with high efficiency.
While other manufacturers are still using “low energy consumption” as a marketing gimmick, Bolong has already achieved a stable, efficient, and sustainable energy-saving mode through intelligent control, hydraulic systems, and heat exchange design.
While ensuring daily processing capacity and organic fertilizer quality, Bolong’s high-temperature aerobic fermentation tank ensures every kilowatt-hour of electricity is scientifically utilized and continuously creates value.
