Fully automatic pet food pellet making machine

Product Overview Extruded feed pellet mills are core equipment in the modern feed industry. Through high-temperature, high-pressure extrusion technology, they transform raw materials such as corn, soybean meal, and fishmeal into nutrient-rich, easily digestible pelleted feed. As a professional feed pellet mill manufacturer, our extruded feed pellet mills, with their advanced twin-screw technology, precise temperature control system, and intelligent operation, provide efficient solutions for livestock, poultry, aquatic, and pet feed production.

Working Principle and Technical Advantages

Core Working Principle
Extrusion Extrusion: Twin screws rotate within a sealed barrel, causing starch gelatinization and protein denaturation of the raw material under high temperatures of 110-180℃ and high pressures of 4-10MPa.
Instant Extrusion: The pressure drops sharply as the material is extruded from the die, causing instantaneous evaporation of moisture and forming porous particles.
Sterilization: High-temperature treatment kills harmful microorganisms such as Salmonella, achieving a sterilization rate ≥99.9%.
Nutritional Retention: Low-temperature extrusion technology retains heat-sensitive nutrients, with a vitamin loss rate ≤5%.

Technical Advantages
Twin Screw Design: Interlocking structure ensures mixing uniformity ≥95%, suitable for high-fiber and high-protein raw materials.
Intelligent Temperature Control: 6-8 independent temperature control segments with an accuracy of ±1℃, preventing nutrient damage.
High Efficiency and Energy Saving: Thermal efficiency ≥85%, more energy-efficient than traditional equipment. 25% Safety and Reliability: Multiple safety systems including automatic feeding, overload protection, and emergency shutdown.
Environmentally Friendly Design: Low noise ≤85dB, dust emissions meet environmental standards.
