I. Overview

The 11FFG series of organic aerobic fermentation tanks are advanced equipment developed based on imported cutting-edge technology, refined and upgraded to suit the varying organic content in different types of organic waste. Designed specifically for the harmless treatment of diverse organic wastes—including livestock and poultry manure, sludge, and food residues—as well as addressing the unique challenges posed by high-humidity and extremely cold climates across different regions, these tanks represent a comprehensive, integrated system tailored for efficient waste management. This equipment leverages the natural decomposition capabilities of microorganisms, enabling a continuous aerobic fermentation process within sealed fermentation tanks over 7 to 12 days. During this period, organic solid waste is effectively deodorized, decomposed, and rendered harmless, ultimately paving the way for its sustainable resource recovery and reuse.

II. Structure

The 11FFG series aerobic fermentation tank for organic materials consists of components such as the power-driven chamber, tank body, agitator shaft, feeding hopper, feeding rack, feeding mechanism, door-opening mechanism, discharge gate, discharge mechanism, upper air blower, lower air blower, temperature gauge, odor eliminator, hydraulic system, and electrical control box.

III. Process Flow

The processing flow of the JFFJG organic matter aerobic fermentation tank equipment includes four stages: mixing and conditioning, feeding, aerobic fermentation, and automatic discharge.

1. Mixing Section

Mix high-moisture manure or organic waste—with a moisture content of around 70%—with recycled materials, biomass, and fermentation microbes according to specific proportions. This process helps adjust the moisture level, C:N ratio, and aeration, ensuring optimal fermentation conditions. If the raw materials already have a moisture content between 55% and 65%, they can be directly fed into the fermentation tank for processing.

2. Aerobic Fermentation Section

This process can be divided into a rapid heating phase, a high-temperature phase, and a cooling phase.

Materials enter the fermentation tank, where they are rapidly broken down within 24 to 48 hours under the action of aerobic bacteria. The heat released during this process causes the material temperature to rise quickly—typically reaching 50–65°C, with peaks as high as 70°C. An air-blowing aeration system evenly supplies oxygen into the tank, ensuring that the fermentation process meets its oxygen requirements and enabling thorough decomposition of the materials. This high-temperature phase is maintained for 5 to 7 days. As the rate of decomposition gradually slows down, the temperature steadily drops below 50°C. The entire fermentation process lasts anywhere from 7 to 15 days. Meanwhile, the increased temperature and enhanced ventilation accelerate the evaporation of moisture from the materials. Excess gases and water vapor are then treated by an odor-control system, which purifies them before releasing the cleaned air and steam back into the environment. This process effectively reduces the volume of the materials, achieving the goals of volume reduction, stabilization, and harmlessness in the treatment process.

3. Automatic Discharging Section

The materials inside the fermentation chamber are layered and fall down after being turned over by the main shaft and under the influence of gravity. Once fermentation is complete, they are discharged as organic fertilizer raw material with a moisture content of less than 30%, enabling the resourceful utilization of organic waste. After the organic fertilizer raw material is released, it is stored in an organic fertilizer warehouse for 20 to 30 days, during which time the temperature stabilizes further, making it ready for direct application to fields.

IV. Working Principle

This equipment utilizes the rapid proliferation and decomposition activity of aerobic microorganisms to carry out fermentation, simultaneously reducing organic waste while evaporating moisture from organic materials—resulting in a simple-to-operate fermentation machine that produces high-quality organic fertilizer. Therefore, it is essential to thoroughly understand the aerobic fermentation process and the factors that influence it.

This equipment does not use moisture-adjusting materials such as sawdust or wood shavings; instead, it simultaneously carries out aerobic high-temperature fermentation of high-moisture raw materials while drying them. Aerobic fermentation is a treatment method that generates minimal odor and helps conserve energy, resulting in the production of premium-quality organic fertilizer.

To promote aerobic fermentation, the following conditions are required: (a) moisture content

For efficient fermentation processing, maintaining an appropriate amount of moisture within the tank is essential. Since the tank typically contains a microbial bed, it’s necessary to carefully introduce high-moisture raw materials—thoroughly mixed and stirred—that have just the right water content. If the raw materials include ingredients like sawdust or wood chips, which vary in density and aeration properties, the required moisture level inside the tank will also differ accordingly. Moreover, to ensure optimal moisture levels throughout the process, the amount of water added should be adjusted based on the moisture content of the input materials, generally kept between 50% and 85%.

(b) Air

The proliferation of aerobic microorganisms required during the fermentation process is influenced by the surrounding environment. This machine continuously supplies air to both the lower and upper sections of the fermentation tank, with airflow adjusted according to the tank's current state. This creates an optimal environment conducive to the vigorous growth of aerobic microorganisms. Additionally, the presence of stirring blades enhances aeration, ensuring consistent product quality throughout.

(c) Humidity

The temperature range of 60–70°C is ideal for the proliferation of aerobic microorganisms, and this machine typically operates at around 65°C during normal operation. After the materials have fully decomposed, the temperature drops to below 50°C.

(d) pH Value, Carbon-to-Nitrogen Ratio

Typically, the pH and carbon-to-nitrogen ratio of organic waste are essential conditions suitable for fermentation—specifically, the pH should remain within the range of 6 to 8.5. However, raw materials treated with lime or sulfuric acid are not ideal for fermentation processes.

V. Characteristics

1. The equipment is compact, can be installed outdoors without requiring a factory building—it’s a mobile processing facility that effectively addresses the high costs associated with factory construction, long-distance transportation, and centralized treatment.

2. Sealed processing, 99% deodorization, zero pollution.

3. Excellent insulation—unaffected by seasonal cold, it can maintain normal fermentation even in environments below -20°C.

4. The fermentation cycle lasts approximately 15 days, and the processing capacity can be increased by installing additional units as needed.

5. Three-layer structure with high-quality mechanical materials, effectively addressing the issue of strong acid and strong alkali corrosion, ensuring a long service life of over 10 years.

6. Simple operation and management—just feed in raw materials like livestock manure, and the system automatically produces organic fertilizer; easy to learn and operate!

7. Low energy consumption, significantly reducing electricity production costs;

8. Aerobic strains can survive and proliferate between -25°C and 80°C, forming beneficial microbial communities that effectively eliminate harmful bacteria in the raw materials—a unique feature that sets this product apart from and makes it superior to other organic fertilizers.

6. Fermentation Operation Method (Example: JFFJG-105)

Continuous Operation Method for High-Moisture Raw Materials (Moisture Content: 50–70%)

The 11FFG series aerobic fermentation tanks for organic materials are developed based on advanced foreign technology, with improvements and upgrades tailored to the varying organic content in different types of organic waste. These tanks have been specifically designed as harmless treatment equipment suitable for handling diverse organic wastes, while also adapting to regions with high humidity and extremely cold climates. This integrated, turnkey system is ideal for efficiently processing organic waste such as livestock and poultry manure, sewage sludge, and food residues. The equipment leverages the natural decomposition process carried out by microorganisms, enabling a continuous aerobic fermentation within a sealed tank over 7 to 12 days. During this process, organic solid waste is effectively deodorized, decomposed, and rendered harmless—ultimately paving the way for true resource recovery and reuse.
