How to Keep Fermentation Tanks Running Efficiently in Winter

When winter arrives and temperatures drop, the fermentation efficiency of organic waste often declines. 

In low-temperature environments, microbial activity slows down, 

causing slower temperature rise, longer fermentation time, and sometimes incomplete composting or odor problems.

For livestock farms, agricultural parks, and manure treatment centers in northern regions, 

maintaining the efficient operation of fermentation tanks during winter is a key factor in achieving sustainable manure resource utilization.

1. Create an Ideal Fermentation Environment

Before running the Aerobic fermentation tank in winter,

 it is important to preheat the feedstock and adjust its moisture content to create a suitable environment for microorganisms.

The faster the temperature rises at the beginning, the more active the microbes become, leading to a smoother fermentation process.

Tips:

Minimize heat loss before loading materials into the tank.

Keep the moisture content between 50–60% to help the system quickly reach the high-temperature phase.

2. Maintain Proper Material Ratios to Boost Microbial Activity

In cold conditions, the raw material ratio becomes more critical since microbial activity is lower.

Recommended parameters:

Moisture content: 50%–60%

Carbon-to-nitrogen ratio (C/N): 25–30

Moderate particle size for better ventilation and aeration

A balanced mix helps the temperature rise quickly, shortens fermentation time, and ensures full decomposition of organic waste.

3. Optimize Aeration and Mixing

JinDi Fermentation Tanks use a bottom aeration system combined with automatic mixing, ensuring even oxygen distribution and a stable aerobic environment throughout the tank.

Key points for winter:

Slightly reduce aeration volume to prevent heat loss.

Adjust mixing intervals based on temperature readings to keep internal conditions stable.

Proper control of aeration and mixing helps maintain a consistent temperature and promotes efficient microbial activity.

4. Strengthen Insulation and Sealing to Reduce Heat Loss

The most important factor in winter operation is insulation.

The tank wall should be equipped with a polyurethane insulation layer, and all openings — 

including inlets, outlets, and inspection ports — should be well-sealed to prevent heat leakage.

A fully enclosed tank design not only maintains internal temperature but also prevents odor emission, ensuring eco-friendly and compliant operation.

5. Use an Intelligent Temperature Control System

Manual monitoring is time-consuming and prone to errors.

JinDi Fermentation Tanks are equipped with a PLC intelligent control system that automatically detects the internal temperature and adjusts heating and aeration levels in real time.

Operators can remotely monitor and control the fermentation process via computer or smartphone, ensuring smart and stable operation even in freezing weather.

6. JinDi Fermentation Tanks — Reliable Performance in All Seasons

Fully enclosed design + efficient insulation: Stable operation under low temperatures

Smart control system: Automatically maintains optimal fermentation temperature

Modular structure: Compact layout and easy installation

7–10 days fast composting: High-temperature aerobic fermentation efficiently converts waste into organic fertilizer

Whether in northern cold regions or mountainous areas with large temperature variations, JinDi fermentation tanks deliver stable performance, energy-saving operation, 

and environmentally compliant discharge throughout the year.

Conclusion

Winter is not an obstacle — it’s a test of equipment and management.

By focusing on insulation, aeration, material ratio, and intelligent control, fermentation tanks can continue to operate efficiently, even in the coldest months.

JinDi fermentation tanks help farms continuously produce high-quality organic fertilizer, supporting green recycling and sustainable manure management all year round.
