Integrated circulating oil pump and cooling fan ensure 24-hour continuous heavy-duty operation without overheating.
• Direct Processing (No Pre-treatment): Handles dry materials (moisture ≤18%) and wet materials (moisture ≤42%) directly. Standard materials like corn, soybean meal, bran, and rice husks require no crushing. High-fiber materials (straw, sawdust) and fermented manure require no drying. Smart constant temperature (80-95°C) ripening eliminates pathogens, improves digestion by 30-35%, and maintains pellet moisture at ≤11% for long-term storage and sea freight.
• Comprehensive Customization for Commercial Scenarios: Comes with replaceable flat dies (3.0-12mm). Adjustable scrapers prevent jamming from high-density materials. Supports global voltage customization (110V-480V), ISO/CE/FDA compliance, and export-grade wooden packaging/fumigation for seamless global transport.
• Intelligent Maintenance & Operation: Constructed with a heavy-duty, pure steel compact frame and universal wheels. Features one-button start, automated feeding/discharging, and a 7-layer safety protection system (overload, material shortage, over-temperature, leakage, blocking, over-voltage, jamming). Quick-release flat die takes less than 10 minutes to replace. The built-in high-pressure cleaning interface allows 2-3 operators to manage daily maintenance effortlessly.
• Cross-Border Export Adaptability: Made of export-grade alloy steel. Can be integrated with elevators and crushers to form a simple production line. Compatible with local cheap raw materials (straw, sawdust, manure) to maximize commercial profit margins. Suitable for pet food, organic fertilizer, and biomass pellets.

Detailed Technical Parameters

The precise parameters of the Model 500 flat die feed pellet machine are categorized into Standard Commercial, Enhanced Heavy-Duty, Diesel-Powered, Hybrid, and High-Power variants, fully accommodating ultra-large commercial and 100,000-ton breeding scenarios.

Application Scenarios & Scope

• 100,000-Ton Scale Livestock Farming: Ideal for intensive, standardized feed processing for poultry and livestock. Customizes pellet size and hardness based on growth stages. Low-temperature ripening ensures high digestion rates, reduces disease risks, and saves 40-45% feed compared to powder feed.
• Mega Commercial Processing: Suitable for massive feed mills and regional cooperatives. Achieves ultra-large batch production with 2-3 operators when paired with a simple production line. Utilizes local cheap raw materials to drastically expand profit margins.
• Cross-Border Export Processing: ISO, CE, and FDA compliant. Supports 110V-480V voltage customization and export packaging. Delivers stable, transport-friendly export-grade pellets for Southeast Asia, Africa, Europe, and South America, offering significant cost-performance advantages.
• Multi-Purpose Expansion: Processes biomass pellets, wood chips, pet food, aquatic feed, and organic fertilizers. Converts agricultural waste (straw, peanut shells, fermented manure) into profitable resources, ensuring green and sustainable development.
• Heavy-Duty Emergency & Outdoor Processing Clusters: Diesel and hybrid variants are ideal for remote off-grid locations, field breeding bases, or post-disaster emergency processing, ensuring uninterrupted operation.

Working Principle

• Feeding Stage: Raw materials (≤18% dry moisture, ≤42% wet moisture) are fed directly into the oversized inlet without pre-crushing. The smart feeder distributes them evenly over the 500mm die. Clearance is adjustable (2.2-3.0mm) via the top nut.
• Extrusion & Pelleting Stage: Driven by the heavy-duty transmission, 8 rollers (with scrapers) compress the material into the die holes. The intelligent closed-loop system maintains 80-95°C for optimal ripening and pathogen elimination, preserving material nutrition.
• Cutting & Discharging Stage: An adjustable heavy-duty stainless steel cutter sections the extruded feed into uniform lengths (5-40mm, 99.8% uniformity). Output moisture is ≤11%, ready for large-scale storage and export sea freight after cooling.
• Safety & Protection: Features a 9-layer safety system, emergency stop, and enclosed safeguards. Operates at ≤75dB with minimal vibration and no oil leakage, supporting 96-hour continuous runs.

Product Advantages & Value

• Ultra-Wide Die Upgrade: 500mm die increases contact area by 25% and capacity by 60% over Model 400. Achieves a 99% pellet forming rate with double the lifespan.
• Energy Efficiency & Cost Reduction: 99.5% transmission efficiency reduces energy consumption by 30%. Eliminates pre-treatment costs, saving labor and maximizing long-term profit margins.
• Omni-Scenario Adaptability: 5 power options (including diesel/hybrid) ensure flexibility. Replaceable dies (3-12mm) support diverse commercial and export orders.
• Intelligent & Durable Maintenance: Automated workflow requires only 2-3 operators. Quick-release die and automatic cleaning system minimize maintenance burdens.
• Nutritional Safety & High-End Quality: 80-95°C ripening improves nutrient absorption by over 50% for high-fiber materials, ensuring premium export-grade pellet quality.
• Cross-Border Adaptability: Multi-certification compliance and independent station SEO-friendly attributes ensure high international market competitiveness, facilitating global market expansion.

Daily Maintenance & Precautions

• Pre-Start Check: Verify connections, roller/die clearance (2.2-3.0mm), lubrication, and cooling systems. Grind the die with oil-mixed feed before first use to ensure smooth discharging.
• During Operation: Prevent metal or stones from entering the feeder. Adjust scrapers to avoid jamming. If blocked, shut down immediately—do not force restart.
• Post-Operation Cleaning: Clean residual materials daily using the high-pressure interface to prevent mold. Check for wear on rollers, dies, and scrapers, replacing them if necessary.
• Regular Servicing: Lubricate transmission parts regularly. Inspect circuits and cooling systems monthly; perform comprehensive maintenance quarterly.
• Storage & Movement: Store in a dry, ventilated area. Secure support legs before moving. Periodically check steel frame welds.
• Safety Operations: Ensure operators are trained. Keep away from rotating parts. Never exceed load capacity and control raw material moisture strictly.
