China generates over 300 million tons of livestock and poultry manure annually. Improper disposal not only pollutes the environment but also represents a massive waste of resources. Processing this manure into organic fertilizer can address environmental challenges while creating economic value—a win-win solution. So how can foul-smelling manure be transformed into high-quality organic fertilizer? What key equipment is required? Lets find out.

Fermentation stage: The core of organic fertilizer production

Fermentation is the soul of the organic fertilizer production line, directly impacting the quality of the finished product. Depending on the production scale, various aeration and turning equipment options are available. Small-scale farms are suitable for hand-held or walk-behind turners, offering flexible and convenient operation; medium-sized enterprises can opt for crawler-type or trough-type turners, which feature high automation and stable efficiency; while large-scale organic fertilizer plants should choose disc-type or chain plate-type equipment, specifically designed for high-viscosity materials, ensuring even aeration and preventing clumping.

For regions with stringent environmental requirements, the intelligent fermentation tank. These fully enclosed devices integrate temperature control, oxygen supply, and stirring functions, reducing the fermentation cycle to 7-10 days, lowering energy consumption by 30%, and effectively preventing odor emissions. The multi-stage temperature control system precisely regulates fermentation temperature, ensuring the elimination of pathogens and weed seeds while preserving the activity of beneficial microorganisms.

Powdered Organic Fertilizer Production Line: Simple and Efficient

The production process of powdered organic fertilizer is relatively simple, with the core consisting of three key stages: "efficient crushing, precise screening, and intelligent packaging." The front end of the production line is equipped with a forklift feeder to achieve automatic material feeding, significantly reducing manual labor intensity. The vertical crusher is responsible for crushing the fermented raw materials into particles smaller than 5mm, with adjustable and uniform particle size.

The drum screening machine is a key component of quality control, effectively separating coarse and fine particles to ensure the purity of the finished product meets standards. The packaging process utilizes a powder packaging machine, combined with belt conveyors and PLC control systems, to achieve quantitative weighing and fully automated bagging operations. This production line requires relatively low investment, making it suitable for small to medium-sized farms or startups.

Granular Organic Fertilizer Production Line: Higher Added Value

The market demand for granular organic fertilizer is robust, with higher added value, but the corresponding equipment configuration is also more complex. In addition to crushing and screening equipment in the pretreatment stage, a professional batching and mixing unit is required. The batching machine can precisely mix various raw materials according to crop needs, while the horizontal mixer ensures uniform nutrient blending.

The granulation and drying unit is a key component in granular fertilizer production. The drum granulator achieves a granulation rate of over 95%, while the disc granulator is more suitable for large-scale continuous production. The subsequent dryer and cooler maintain the particle moisture content below 12%, ensuring stable product quality. The granule screening machine separates qualified products, with unqualified particles being recycled for regranulation, significantly improving raw material utilization.

The high-end production line is also equipped with a film-coating machine and an intelligent packaging system. The film-coating process enhances the gloss and moisture resistance of the particles, while the automatic packaging machine, in conjunction with the palletizing machine, achieves full automation from weighing and sealing to stacking.
