Rotary Drum Fermentation Tank Product Overview
The MAXTON rotary drum fermentation tank is a fully enclosed dynamic composting system that breaks through the limitations of climate and site conditions. Using a horizontal rotating drum with specially designed internal flight plates, combined with a precision forced aeration system, it creates an optimized environment for aerobic thermophilic and thermotolerant microorganisms to thrive.
Enclosed Aerobic Composting Technology
The horizontal drum integrates solid waste mixing, aerobic degradation, temperature/humidity control and exhaust gas collection in one enclosed vessel. Drum rotation with internal flight plates tumbles material for uniform aeration, while built-in sensors maintain optimal 55–70°C fermentation temperatures.
Rapid Fermentation & Moisture Reduction
Dynamic tumbling and forced ventilation combine to accelerate microbial decomposition. Aerobic fermentation completes in just 7–10 days, reducing material moisture from 60–80% down to 30–40% — ready for direct granulation or sale as stabilized organic fertilizer.
Space-Efficient & All-Weather Operation
The horizontal compact design saves 70%+ land area versus traditional windrow composting. The drum body is wrapped with 50–100mm polyurethane insulation, enabling normal high-temperature fermentation even in -20°C winter conditions.

Working Principle & Core Advantages
After startup, raw material enters the horizontal drum through the feed inlet. The drum rotates slowly under a variable-frequency motor drive. Specially designed internal flight plates continuously lift material and drop it, creating a cascading "curtain" effect that maximizes gas-solid contact area. Simultaneously, a high-pressure centrifugal fan forces fresh air into the drum through the main shaft or bottom ventilation pipes.
Aerobic microorganisms multiply rapidly in the oxygen-rich environment, decomposing organic matter and releasing substantial biogenic heat. Internal temperature quickly rises to 55–70°C, which not only accelerates moisture evaporation but also thoroughly destroys pathogens, parasite eggs and weed seeds. Exhaust gas is extracted by an induced draft fan into the deodorization system for compliant discharge.
Zero Odor Emission
Fully enclosed negative-pressure operation with dedicated suction ports. Exhaust gases are channeled to chemical scrubber towers or biological deodorization filters for complete compliance.
70%+ Land Saving
Highly integrated horizontal design requires 70%+ less land area compared to traditional trough composting systems. Ideal for space-constrained facilities near urban or residential areas.
Technical Deep Dive: Core Technology & High-Quality Fertilizer Production
Dynamic Balance of Mass Transfer and Heat Transfer
The core technical challenge of the horizontal rotary drum design lies in the "dynamic balance of mass transfer and heat transfer". In static composting, the center temperature is too high and easily causes microorganisms to "burn out," while the edge temperature is too low to achieve sterilization. The MAXTON rotary drum fermentation tank overcomes this through precision fluid dynamics design — air forms uniform micro-positive-pressure penetration (maximizing Oxygen Transfer Efficiency, OTE) through the pores of the tumbling material. Additionally, the internal flight plate angles have been optimized through multiple mechanical simulations to ensure material forms a loose cascading "curtain" when falling, maximizing gas-solid contact area. This design not only guarantees absolute uniformity of the internal temperature field but also effectively prevents caking of high-moisture materials.
Advantages in Fertilizer Production Lines
In commercial fertilizer production lines, the rotary drum fermentation tank serves as the core front-end preprocessing stage. Its advantages include:
- Raw Material Homogenization: The drum rotation itself is an excellent mixing process, evenly blending carbon sources (such as sawdust), nitrogen sources (manure) and moisture into a uniform mixture.
- Foundation for Granulation: After fermentation, material moisture drops to 30–40% with highly stabilized organic matter. When feeding directly into downstream crushing and granulation systems (such as drum granulators or extrusion granulators), balling rates are higher and finished product strength is significantly improved.
How to Ferment High-Quality Fertilizer
The core of producing high-quality organic fertilizer lies in the degree of humification. This equipment uses precise probes to monitor real-time data inside the drum:
- Heating Phase: Accelerates decomposition of easily degradable organic matter (sugars, proteins).
- High-Temperature Maintenance: Stabilizes around 60°C for 3–5 days, promoting cellulose and hemicellulose degradation while destroying harmful substances.
- Humic Substance Synthesis: Sufficient oxygen supply prevents harmful amine and hydrogen sulfide generation from anaerobic fermentation, preserves large amounts of ammonium nitrogen, and promotes polymerization of macromolecular substances into humic acid with excellent water and fertilizer retention properties. Final output shows dark brown color with earthy fragrance and minimal nutrient loss.
3 Common Mistakes in Commercial Composting (And How MAXTON Solves Them)
As a leading organic fertilizer equipment manufacturer, we often see facilities struggle with these three issues when trying to scale up their operations.
Mistake 1: Ignoring C:N Ratio
The Problem: Attempting to compost pure chicken manure (nitrogen-heavy) directly leads to massive ammonia loss, foul odors, and toxic compost.
The Solution: Our engineers provide precise blending formulas (adding sawdust/straw) to achieve the optimal 25:1 Carbon-to-Nitrogen ratio before entering the rotary drum.
Mistake 2: Anaerobic Core Zones
The Problem: Traditional static piles suffer from "cold edges" and "oxygen-starved cores," leading to incomplete sterilization and hydrogen sulfide production.
The Solution: The MAXTON internal flight plate design creates a continuous "falling curtain" of material, ensuring 100% uniform forced aeration and consistent 60°C+ temperatures.
Mistake 3: Weather Vulnerability
The Problem: Heavy rain or sub-zero winters can halt open-air windrow composting entirely, disrupting supply chains.
The Solution: Our enclosed rotary tanks feature 50-100mm polyurethane insulation. The exothermic microbial reaction sustains high temperatures inside the drum, ensuring 365-day operation regardless of external weather.

Why Pilot-Scale Material Testing Is Critical
In the organic solid waste treatment field, no two batches of material are identical. For example, egg-laying hen manure and broiler manure differ significantly in moisture content and C:N ratio. After mixing different proportions of rice husk or sawdust, the material's porosity and bulk density change dramatically. Deploying large equipment without testing can easily result in motor overload, internal anaerobic odor generation, or insufficient moisture reduction.
Pilot-scale testing is therefore the cornerstone of project success. MAXTON's pilot laboratory determines:
- Optimal aeration volume — determines fan power and ventilation pipe layout
- Volume reduction ratio — determines required drum capacity for actual daily processing needs
- Corrosion intensity — determines required anti-corrosion material grade for inner liner
- Optimal C:N amendment ratio — written into equipment SOP (Standard Operating Procedure) to guide daily operations after commissioning

Rotary Drum Fermentation Tank FAQ
Comprehensive answers to the most common technical and operational questions.
What is a rotary drum fermentation tank?
A rotary drum fermentation tank is an enclosed horizontal composting vessel that integrates solid waste mixing, aerobic degradation, temperature/humidity control and exhaust gas collection. It uses drum rotation with internal flight plates to tumble and aerate organic waste, combined with forced aeration, to achieve rapid aerobic fermentation in 7–10 days.
How long does rotary drum fermentation take?
High-temperature aerobic fermentation typically takes 7–10 days depending on raw material type, initial moisture content and ambient temperature. The enclosed system maintains temperatures of 55–70°C throughout, compared with 30–90 days for traditional windrow composting.
Can odor be controlled?
Yes. The equipment operates under fully enclosed negative pressure. Exhaust gas is drawn through dedicated suction ports into chemical scrubber towers or biological deodorization filter systems. The treated gas fully complies with national and regional environmental emission standards.
Is fermentation inoculant required?
Professional high-temperature aerobic fermentation inoculant is recommended only during initial commissioning. Once the system enters normal daily operation, the drum retains a large population of highly active thermophilic bacteria, so additional inoculant is typically unnecessary, significantly reducing operating costs.
