The cow mattress material regeneration system is an innovative technology that converts cow manure into reusable bedding. The following provides a detailed analysis from the perspectives of core principles, technological advantages, and future trends:

I. System Principles and Technical Details

1. Solid-Liquid Separation
   Through screw-press separators, coarse fibers (e.g., undigested corn, hay) in cow manure are separated from liquids. The moisture content of solid dry matter is reduced from 80% to 58%-62%, facilitating subsequent fermentation. The separated liquid enters a biogas digester for field application.

2. High-Temperature Aerobic Fermentation
   Solid manure enters a fermentation chamber where natural microorganisms drive aerobic fermentation, maintaining temperatures between 65-75°C. This prolonged high temperature effectively eliminates over 99% of harmful pathogens (e.g., mastitis-causing bacteria). Auxiliary heating systems (e.g., biogas-powered hot air) enhance efficiency, ensuring bedding moisture below 50%.

3. Automated Control
   Equipped with a PLC control system, the process operates automatically, including temperature monitoring, ventilation adjustment, and material discharge. Remote monitoring capabilities via smartphones or computers improve management convenience.

II. Core Advantages

1. Economic Benefits

• Cost Comparison: Bedding costs are reduced to 33% of sand, 15% of rubber mats, and 20% of rice husks. For a 4,000-cow farm, annual savings reach approximately 1.1 million yuan.
• Resource Cycling: Manure is "transformed into treasure," resolving waste disposal issues while replacing traditional bedding materials (e.g., rice husks, sawdust), reducing procurement dependencies.

2. Enhanced Animal Welfare

• Comfort: Fermented bedding is soft and breathable, increasing cow lying time by 10%-15% and reducing limb diseases.
• Health Assurance: Pathogens in bedding are minimized after high-temperature sterilization, reducing mastitis incidence.

3. Environmental Benefits

• Pollution Control: Waste is utilized as a resource, preventing direct environmental contamination.
• Carbon Reduction: Compared to traditional bedding transportation and incineration, the system reduces carbon emissions by about 40%.

III. Future Trends

1. Intelligent Upgrades
   Integrate IoT and AI algorithms for adaptive fermentation process adjustments, further enhancing efficiency.
2. Multi-Waste Synergy
   Explore co-fermentation of agricultural waste (e.g., straw, mushroom residues) with manure to improve bedding nutrition and water absorption.
3. Carbon Trading Potential
   As carbon markets mature, the system's emission reductions could participate in carbon trading, generating additional revenue for farms.

Conclusion: The dairy cow bedding recycling system is a model solution for sustainable livestock development, achieving a closed-loop cycle of "manure → bedding" and enhancing economic, environmental, and animal welfare outcomes. For large-scale farms, its long-term benefits and eco-value far outweigh initial investments, warranting prioritized attention and promotion.
