Closed Fermentation Tank

Closed Fermentation Tank – YXFJG-280 Vertical Aerobic Fermentation System 

Industrial-grade vertical aerobic fermentation system Henan Yuxing's Closed Fermentation Tank YXFJG-280 treats high-throughput organic waste. In just 7-12 days, this enclosed bioreactor converts animal manure, sewage sludge, and agricultural leftovers into stable organic fertilizer with a tank volume of ≥280m³ and daily feeding capacity of 18-24m³. With 113.37kW installed power, 51kW operating power, and 115㎡ floor space, the system consumes up to 80% less land than standard windrow composting.

The tank, made of corrosion-resistant materials and insulated with ≥53mm polyurethane, maintains appropriate thermophilic temperatures (55-65°C) in sub-zero conditions Precision temperature, moisture, and oxygen monitoring is achieved with integrated PLC + HMI + remote control. A specialized 5.5kW bio-filter tower and 15m chimney reduce volatile organic compounds for zero-odor operation. Yuxing provides complete solutions with lifetime technical support and 20 years of industry experience and CE certification.

Technical Specifications

How It Works

The product uses advanced four-phase aerobic decomposition.

Raw organic materials enter through a 1.5m³ feeding hopper with a 4kW lifting mechanism. The sealed tank environment activates immediately after loading. High-torque motors drive multi-stage mixing paddles to continually agitate substrates at preset intervals, eliminating short-circuiting and guaranteeing uniform oxygen distribution in the 280m³ volume.

The PLC control system monitors real-time temperature probes to sustain thermophilic fermentation. Automated aeration blowers introduce precisely measured fresh air when microbial activity exceeds 55-65°C. Forced ventilation maintains temperature and provides aerobic microorganisms with 8–12% oxygen.

A central vent manifold collects all exhaust gasses. The 5.5kW deodorization fan filters volatile compounds through a 1x5m bio-filter tower with specific microbial medium. The 15m chimney releases clean air after this biological cleaning mechanism breaks down ammonia, hydrogen sulfide, and other odor compounds.

The ≥53mm polyurethane insulation layer functions as a thermal barrier, ensuring steady interior temperatures regardless of weather. Under zero temperatures, optional electric heating coils automatically activate to maintain fermentation efficiency. Stabilized compost is released from the bottom outlet after 7-12 days of processing, producing 7-10m³ of pathogen-free organic fertilizer daily.

Core Technical Advantages

Small Footprint, High Land Efficiency

Vertical design uses 80% less land than windrows. The 115◡ installation footprint processes quantities comparable to over 500◡ in open composting yards.

Odorless Enclosed Processing

Airtight construction eliminates secondary pollutants. All gases are bio-filtered to fulfill urban and peri-urban environmental standards. The neighboring communities have no odor complaints.

Operating Reliability in All Climates

In -30°C winters, integrated insulation and heating sustain 55-65°C fermentation temperatures. Northern facilities operate year-round without seasonal shutdowns.

Automated Process Control

Real-time PLC monitoring regulates aeration, mixing, and temperature. HMI touchscreens show fermentation data. Remote troubleshooting and process improvement are possible.

Fast 7-12 Day Cycle

Optimised oxygen transport and heat recovery speed microbial breakdown. You double yearly tank output by stabilizing compost in half the time used traditionally.

Modular Scalability

The YXFJG-280 fits multi-tank arrays well. Add parallel units to production plants to grow capacity without infrastructure reconfiguration. Centralized SCADA controls several tanks.

Industrial Applications 

Municipal Sewage Sludge Treatment

Environmental engineers use this Closed Fermentation Tank to aerobically stabilize dewatered biosolids quickly. The sealed device turns hazardous sludge into Class A compost for agricultural use without releasing pathogens.

Big Livestock Operations

Pork, dairy, and poultry farms treat waste on-site. The small size fits existing infrastructure, and home odor control systems comply with environmental regulations.

Valuing Agricultural Waste

Crop and food processors make organic fertilizer from fruit pomace, vegetable scraps, and straw. High-moisture substrates that decay in windrows are handled in the controlled environment.

Industrial Organic Waste Management

Breweries, distilleries, and food makers treat discarded grains and byproducts. Acidic and high-sugar substrates damage traditional equipment, while the system's stainless steel structure resists.

​​​​​​​Quality Assurance & Testing Protocols

Yuxing implements rigorous quality control throughout manufacturing and delivery.

Weld Integrity Verification

All structural welds undergo Ultrasonic Testing (UT) to detect microscopic flaws. Pressure-critical seams pass radiographic inspection ensuring zero-leakage performance in continuous operation.

Surface Finish Standards

Internal contact surfaces are polished to Ra < 0.8μm. This sanitary finish prevents microbial biofilm formation and facilitates thorough cleaning between batches.

Pressure & Vacuum Resilience

Each tank completes hydrostatic testing at 1.5× design pressure. Vacuum hold tests verify seal integrity under negative pressure conditions during exhaust cycling.

Agitation System Load Testing

Mixing mechanisms undergo full-load torque testing with simulated high-viscosity substrates. Gearboxes and drive shafts are validated for 10-15 year duty cycles under continuous operation.

CIP Coverage Validation

Bio-filter spray systems pass riboflavin tracing tests. UV inspection confirms complete internal coverage, eliminating cleaning dead zones that harbor contaminants.

Control System Simulation

PLC programming undergoes fault-injection testing. Emergency shutdown protocols, sensor failure responses, and alarm cascades are validated before shipment.

Customization & Global Compliance

Yuxing's ODM/OEM capabilities adapt the product to diverse international markets.

Electrical Standards Adaptation

Standard 380V/50Hz systems customize to 480V/60Hz, 440V/50Hz, or 415V/50Hz. Siemens and Schneider component integration ensures compatibility with regional service networks.

Certification Compliance

CE-marked units meet EU machinery directives. Optional ATEX certification for explosive atmospheres and ASME BPE for pharmaceutical applications available upon request.

Climate-Specific Engineering

Tropical configurations include enhanced ventilation and corrosion-resistant coatings. Arctic models feature double-insulation and thermal oil heating systems for -40°C ambient operation.

Multi-Language Interfaces

HMI touchscreens program in English, Spanish, Russian, Arabic, and French. Operator manuals and maintenance documentation localized to your team's language.

Capacity Scaling

Daily processing requirements from 10m³ to 50m³ accommodate through tank diameter and height adjustments. Modular design maintains performance-to-footprint ratios across scales.

FAQ

Q1: How does the system eliminate odors completely?

A: All exhaust gases route through a bio-filter tower packed with specialized microorganisms that metabolize ammonia, hydrogen sulfide, and volatile fatty acids. The 15m chimney disperses treated air well above ground level, ensuring zero odor at property boundaries.

Q2: Can the tank operate during extreme winter cold?

A: Yes. The ≥53mm polyurethane insulation retains microbial heat generation. Optional electric or thermal oil heating systems activate automatically when temperatures drop, maintaining 55-65°C fermentation regardless of external conditions down to -30°C.

Q3: What is the expected lifespan of the mixing system?

A: With proper lubrication and mechanical seal maintenance, the agitator assembly is engineered for 10-15 years of continuous duty. Wear-resistant alloy paddles and reinforced drive shafts withstand abrasive organic materials.

Q4: How do you prevent material short-circuiting in continuous feeding?

A: Internal baffle plates and multi-stage mixing paddles create a controlled First-In-First-Out (FIFO) flow pattern. PLC programming sequences agitation to ensure uniform 7-12 day residence time for all material.

Q5: What power infrastructure is required for installation?

A: The YXFJG-280 requires AC380V three-phase power with 113.37kW capacity. A dedicated transformer and distribution panel should supply the control system, motors, and heating elements with appropriate overload protection.
