Core Process Flow

1. Raw Material Pretreatment: Sort and crush organic wastes to remove impurities like stones and metals. Adjust moisture content and carbon-nitrogen ratio to prepare for fermentation.
2. High-Temperature Aerobic Fermentation: Feed pretreated raw materials into fermentation equipment (such as trough-type turners, windrow turners). Control temperature and supply oxygen via turning to promote microbial decomposition of organic matter. Achieve harmlessness (kill pathogens and insect eggs) and maturation, with a fermentation cycle of 7-15 days typically.
3. Post-Treatment Processing: Crush and screen matured materials to remove incompletely decomposed impurities. Add functional strains or auxiliary materials as needed to enhance fertilizer efficiency.
4. Granulation Molding: Use equipment like double-roll extrusion granulators or disc granulators to process powdery materials into granular form, facilitating storage, transportation and application.
5. Drying and Cooling: Dry the granules to reduce moisture to the standard range, then cool them. Improve particle stability and prevent caking or deterioration.
6. Screening and Packaging: Remove unqualified granules through screening. Qualified products are weighed and sealed by automatic packaging machines to complete the finished product delivery.

Key Equipment Composition

• Pretreatment Equipment: Crushers, mixers, screening machines (for impurity removal).
• Fermentation Equipment: Trough-type turners, windrow turners, fermentation tanks (closed fermentation).
• Processing Equipment: Secondary crushers, mixers (for adding strains/auxiliary materials).
• Granulation Equipment: Double-roll extrusion granulators, disc granulators, drum granulators.
• Drying and Cooling Equipment: Dryers, coolers.
• Post-Treatment Equipment: Finished product screening machines, automatic packaging machines, belt conveyors (for material transfer).

Core Advantages

• Waste Recycling: Solve the pollution problem of organic wastes and realize resource recycling.
• Excellent Fertilizer Effect: Organic fertilizer is rich in organic matter and trace elements. It can improve soil quality and crop quality, meeting the needs of green agriculture.
• Environmental Compliance: High-temperature harmless treatment during fermentation avoids secondary pollution, with emissions meeting environmental standards.
• Flexible Adaptability: Customize production line configurations according to raw material types and capacity requirements (small-scale: 0.5-1 ton/hour, large-scale: 5-10 ton/hour).

Applicable Raw Materials and Finished Products

• Applicable Raw Materials: Livestock and poultry manure (chicken manure, cow manure, sheep manure), crop straw, food waste, mushroom residue, distiller's grains, traditional Chinese medicine residue and other organic wastes.
• Finished Product Types: Granular organic fertilizer, powdered organic fertilizer, compound organic fertilizer (added with nitrogen, phosphorus and potassium nutrients), bio-organic fertilizer (added with functional microorganisms).
