Zero-Waste Cow Dung Bedding Processing Unit and Fertilizer Pre-Treatment Machine

Product Overview

Achieving complete resource utilization in dairy farm manure management requires systems capable of handling both barn bedding recovery and downstream organic fertilizer processing without environmental discharge. The Zero-Waste Cow Dung Bedding Processing Unit and Fertilizer Pre-Treatment Machine is an advanced dual-purpose waste treatment system engineered specifically to process raw cattle dung into two high-value end products: clean, sanitized Recycled Manure Solids (RMS) for cattle stall bedding and pre-conditioned organic compost feedstock for fertilizer manufacturing.

Operating under a zero-waste process flow, raw cattle slurry is first conveyed to a high-efficiency stainless steel screw-press separator that splits the manure into liquid and solid phases. The liquid fraction is directed to biogas digesters or liquid fertigation storage, while the solid fraction undergoes controlled thermophilic aerobic fermentation in a closed-loop vessel. Natural biological self-heating (60–70°C) eradicates mastitis pathogens, coliforms, and weed seeds. A portion of the processed, odorless solids is diverted for immediate stall bedding reuse, while the remaining nutrient-rich solids undergo conditioning—including precise moisture adjustment and fine crushing—serving as ideal pre-treated feedstock for organic fertilizer granulating plants. Manufactured by Gofine Machine with heavy-duty drive components, acid-resistant stainless steel wetted parts, and automated PLC control, this unit eliminates farm waste discharge, slashes bedding expenses, and creates an additional revenue stream through fertilizer raw material preparation.

Key Features & Technical Advantages

• Non-Separator One-Step Processing: Handles high-moisture raw manure directly without clogging or requiring pre-dewatering equipment, simplifying farm operations.
• 100% Organic Matter Retention: Preserves all soluble nutrients and fine fibers that are typically lost in traditional pressing processes, producing superior quality bedding.
• Thermal Agitation & Rapid Sterilization: Combines thermal heating with aerobic microbial fermentation (60°C–75°C) to kill 99%+ of pathogens (E. coli, Staphylococcus aureus, molds) within hours, ensuring maximum biosecurity.
• Smart PLC Automation: Integrated temperature, moisture, and oxygen sensors automatically adjust heating power, mixing speed, and ventilation for reliable 24/7 operation.

Applications

• Large-Scale Dairy Farms (Free-Stall Barns): Directly replaces expensive purchased sand, wood shavings, and rice husks, resolving supply chain shortages and significantly reducing farm bedding procurement expenses.
• High-Viscosity & Sand-Laden Manure Processing: Specifically designed for farms using scrapers or environments where manure contains dirt and sand, resolving the frequent wear, tear, and clogging associated with traditional separation machines.
• Eco-Circular Farms & Agricultural Parks: Ideal for creating modern demonstration projects featuring zero-waste emissions, high ROI, and total resource recycling.

Organic Fertilizer Production Line Integration
Our system is not only an advanced bedding recovery unit, but it also serves as an efficient pre-treatment system for organic fertilizer production lines.

• Nitrogen Enrichment: After multiple uses in dairy stalls, the recycled bedding absorbs rich nitrogen from bovine urine, naturally optimizing the Carbon-to-Nitrogen (C/N) ratio to the ideal range for composting.
• Pre-Sterilized Raw Material: The spent bedding is pre-sterilized and partially decomposed, requiring significantly less time for secondary composting.
• Fertilizer Processing: Through subsequent screening, crushing, granulating, and drying processes, the spent material is transformed into premium commercial organic fertilizer, achieving 100% zero-waste, high-ROI circular farming.

Frequently Asked Questions

• How does this non-separator system handle high-moisture raw manure?
  The system utilizes a combination of high-torque mechanical agitation and controlled thermal heating. The internal temperature quickly reaches aerobic fermentation levels, evaporating moisture through controlled ventilation while transforming raw manure into dry, fluffy bedding.
• Does recycled bedding increase the risk of mastitis in dairy cows?
  No. The dual-control thermal sterilization process kills over 99% of pathogenic bacteria (E. coli, Staphylococcus aureus, and molds). The resulting bedding is hygienic, dry, and safe, promoting cow lying time and milk production.
• Can spent bedding be turned into commercial organic fertilizer?
  Yes. Spent bedding absorbs nitrogen from cow urine during stall use, creating an optimal C/N ratio. After secondary composting, it passes through screening, crushing, granulating, and drying equipment to produce high-grade organic fertilizer.
