The vertical fermentation tank is the core equipment in modern organic fertilizer production, converting organic waste into high-quality fertilizer through controlled fermentation conditions, featuring high space utilization and automation levels.
The vertical fermentation tank is crucial in the organic fertilizer making process, efficiently decomposing organic waste through aerobic fermentation. It serves as a core component of organic fertilizer making machines, providing controlled temperature and aeration to accelerate material breakdown while killing pathogens, ensuring high-quality fertilizer production.
What is a Vertical Fermentation Tank?
A Vertical Fermentation Tank is a vertically installed cylindrical container specifically designed for aerobic fermentation processes. The tank height is typically 2-3 times its diameter, equipped with aeration systems, mixing devices, and temperature/humidity control units[1].
Key Functions and Advantages
- Efficient Fermentation: Completes in 7-15 days what traditional composting requires 60 days, through forced aeration and mechanical mixing
- Environmental Control: Enclosed design effectively collects odors and volatile compounds for treatment before emission
- Space Saving: Vertical structure saves over 75% space compared to traditional flat composting
- Year-round Production: Unaffected by weather conditions, enabling 365-day continuous operation[2]
Typical Applications
- Livestock manure treatment: Efficient processing of chicken/pig manure
- Food waste recycling: Conversion into organic fertilizer
- Municipal sludge treatment: Stabilization of sewage sludge
- Agricultural waste utilization: Fertilizer production from straw, fruit residue, etc.
