60% Wet Chicken Manure Pellet Production Line in Vietnam

RICHI MACHINERY

Project Background and Client Profile

The client for this organic fertilizer production project is a medium-scale agricultural cooperative based in the Mekong Delta region of Vietnam. This cooperative operates several poultry farms producing high volumes of broiler and layer manure, which previously caused environmental concerns due to improper disposal. The cooperative aimed to convert this waste into a valuable product, aligning with the Vietnamese government’s initiatives promoting organic fertilizers and sustainable agriculture.

The decision to implement a 60% wet chicken manure pellet production line stems from several strategic considerations:

• Raw Material Availability: Vietnam produces large quantities of chicken manure, and rice straw is abundant post-harvest.
• Market Demand: The demand for organic fertilizer is rising among smallholder farmers seeking environmentally friendly alternatives to chemical fertilizers.
• Environmental Compliance: National regulations encourage proper treatment of livestock waste, reducing ammonia, hydrogen sulfide, and pathogen emissions.
• Economic Feasibility: Converting poultry waste to pellets reduces disposal costs and generates additional revenue through fertilizer sales.

The wet chicken manure pellet production line in Vietnam has an hourly processing capacity of approximately 7-8 t/h for wet chicken manure and straw residues, achieving an annual output of 18,000 tons of organic fertilizer. The products include 20–50 kg bagged organic fertilizers suitable for soil conditioning, nutrient supplementation, and sustainable crop production.

Raw Materials

The organic fertilizer production line relies on two primary raw materials: wet chicken manure (60% moisture) and rice straw residues. Additionally, multifunctional microbial inoculants are used to enhance the fermentation process.

Table: Raw Materials Consumption and Storage

In Vietnam, rice straw is available seasonally after harvest. Chicken manure is produced daily by the cooperative’s poultry operations. Proper storage and moisture control are critical to maintain feedstock quality and prevent odor generation prior to processing.

Product Scheme

Upon completion, the wet chicken manure pellet production line in Vietnam will generate 18,000 tons of organic fertilizer annually, with products packaged in 20–50 kg bags suitable for agricultural use.

Table: Product Specifications

The biological organic fertilizer produced follows the NY884-2012 standards, ensuring:

• Viable bacteria ≥ 0.2 × 10⁹ CFU/g
• Organic matter ≥ 40% (dry basis)
• Moisture ≤ 30%
• pH 5.5–8.5
• Fecal coliform ≤ 100/g

Production Process

The 60% wet chicken manure pellet production line in Vietnam uses a combination of aerobic high-temperature fermentation and mechanical granulation. The process flow is divided into the following stages:

1. Preprocessing and Fermentation

Rice straw is crushed and mixed with wet chicken manure in a 1:2 ratio using an integrated mixer. Heat treatment at 120°C sterilizes pathogens while maintaining a suitable environment for beneficial microbes. Multifunctional microbial inoculants are introduced to accelerate fermentation. The fermentation cycle lasts 15–20 days, with temperature, moisture, and oxygen carefully monitored.

2. Granulation and Sieving

Post-fermentation material is fed into a disc pelletizer to produce 3–7 mm diameter pellets. Sieving ensures particles are uniformly sized: 2.0–4.5 mm pellets proceed to drying, <2 mm returned to pelletizer, >4.5 mm sent to pulverizer for resizing.

3. Drying

Rotary dryers with direct electric heating reduce moisture content below 30%, using counterflow hot air and continuous material lifting for uniform drying.

4. Cooling

Pellets are cooled in rotary cooling drums using natural airflow to achieve ambient temperature before packaging.

5. Packaging

Final pellets are packaged in 20–50 kg woven bags and stored in the warehouse, ready for distribution.

Project Prospects and Market Analysis

Vietnam has over 1.2 million tons of chicken manure produced annually, much of which remains underutilized. Organic fertilizer demand is rising due to increasing awareness of sustainable farming and soil health. This 60% wet chicken manure pellet production line addresses environmental challenges while creating economic opportunities:

• Revenue Generation: Selling organic fertilizer at USD 300–400/t yields annual revenue ~USD 5.4–7.2 million.
• Environmental Compliance: Reduces NH3 and H2S emissions; improves soil health.
• Export Potential: Fertilizer can be exported to nearby Southeast Asian markets.

RICHI Machinery’s turnkey solutions, including equipment, engineering services, and operational guidance, make this project highly feasible, replicable, and profitable in Vietnam and similar tropical countries.
