Product Overview
The Organic Fertilizer Aerobic Fermentation Compost Cover System is an intelligent environmental control device designed to optimize the aerobic composting process of organic fertilizer raw materials. It integrates temperature/humidity monitoring, automatic ventilation, and thermal insulation coverage to create a stable microenvironment for microbial activity—accelerating the decomposition of organic matter (e.g., manure, straw) while reducing odor emissions. Made of UV-resistant PVC-coated polyester fabric (thickness 0.8 mm) and aluminum alloy support frames, it is suitable for open-air or workshop-based large-scale compost piles (50-200 m² per unit). Unlike traditional manual covering methods, it realizes automated control of fermentation parameters, shortening composting time by 20-30%.
Product Features
Intelligent Environmental Control: Equipped with 6-8 temperature/humidity sensors (embedded in the compost pile) that transmit real-time data to a PLC control system. When temperature exceeds 65℃ (optimal for thermophilic microbes), the system automatically opens the ventilation valves; when humidity drops below 50%, it triggers the spray humidifier.
Durable Cover Material: The PVC-coated fabric is resistant to UV radiation (service life 5 years), acid/alkali corrosion (resistant to pH 3-11), and tearing (tensile strength ≥3000 N/m), suitable for outdoor use in harsh weather (rain, snow, strong wind).
Modular Design: Each unit covers 50-200 m² of compost pile, and multiple units can be connected in parallel to adapt to large-scale compost yards (e.g., 1000 m² yards require 5-20 units). The support frame is assembled with quick-connect bolts for easy installation.
Odor Reduction: The semi-sealed cover traps ammonia and hydrogen sulfide, which are then treated by an optional exhaust gas scrubber (attached to ventilation pipes), reducing odor concentration by ≥80% compared to uncovered piles.
Energy Efficiency: The system operates on a 0.75-2.2 kW motor (for ventilation and humidification), consuming only 5-12 kWh/day per unit—30% less energy than traditional heated composting systems.
Applications
Large-scale organic fertilizer plants: Covering compost piles of animal manure + straw to accelerate decomposition (composting time reduced from 45 days to 30 days).
Municipal organic waste treatment centers: Processing kitchen waste and garden waste into compost, with odor control meeting urban environmental standards.
Livestock farms: On-site composting of manure to avoid environmental pollution, with the cover system preventing rainwater from leaching nutrient-rich wastewater.
Agricultural cooperatives: Small-scale composting of crop straw and poultry manure to produce localized organic fertilizer for farm use.
FAQ
Q: How to monitor and control the system remotely?
A: The PLC system supports WiFi/4G connectivity, allowing operators to view real-time data (temperature, humidity, valve status) and adjust parameters via a mobile app (compatible with iOS/Android). Alerts are sent via SMS if parameters exceed set ranges.
Q: Can the cover withstand heavy snow?
A: The support frame has a snow load capacity of 15 kg/m² (equivalent to 15 cm of fresh snow). For regions with heavy snowfall, an optional snow-melting system (electric heating wires embedded in the frame) is available.
Q: How often to clean the cover material?
A: Clean the surface with high-pressure water (≤3 MPa) every 3 months to remove dust and compost residues. Avoid using chemical cleaners to prevent damage to the PVC coating.
Q: What is the installation time for one unit?
A: A 2-person team can install a 50 m² unit in 4-6 hours, including frame assembly, cover installation, and sensor calibration. Larger units (200 m²) take 8-10 hours.
