Key Features and Benefits

  • Industrial fat screw press machine for animal by-product rendering

    High Oil Recovery Efficiency

    Equipped with an advanced three-stage spiral pressing system, the machine separates raw material into high-quality crude oil and pressed cakes. The residual oil content of the cakes can be as low as 9%–14%, ensuring a high oil recovery rate.

    Hydraulic Cake Head for Maximum Extraction

    At the outlet, a hydraulic cake head enhances the density of pressed cakes and increases the oil yield, guaranteeing the maximum value from every batch of raw material.

    Robust and Reliable Design

    The machine adopts a single conical screw structure that effectively presses oil into the surrounding shell. With heavy-duty construction and wear-resistant materials, it ensures long-term stable operation and low maintenance.

How the Fat Press Machine Works



  • Raw materials from the rendering cooker are fed into the screw press chamber.

  • The single conical screw guides the material through the press, squeezing oil into the surrounding shell.

  • Pressed solids are converted into cakes and discharged smoothly through a dedicated outlet.

  • The recovered oil, containing small fine particles, flows into a collection tank. A secondary screw gently pushes the oil toward the outlet, keeping it pure and free from solid impurities.

This process not only achieves the separation of oil and solids but also simplifies downstream purification.

Applications in Rendering Industry

Our fat oil press machines are widely applied in different rendering processes, from raw material defatting to protein meal preparation, delivering consistent performance and improved product quality.

  • Animal Rendering Plants

    High-efficiency fat recovery.

  • Meat & Bone Meal Production

    Preparing defatted protein meal with higher value.

  • Poultry By-Product Processing

    Stable performance on mixed inputs.

  • Feed Ingredient Processing

    Producing raw materials with enhanced stability.

Benefits of Defatting with Fat Oil Press Machines

  • Improve Meat and Bone Meal Quality

    • Higher protein content: Removing fat increases the relative proportion of protein in meat and bone meal, enhancing nutritional value.
    • Better digestibility: Defatting improves protein digestibility, making nutrients easier to absorb.

  • Improve Physical Properties

    • Improved flavor and color: Defatted meal looks and tastes cleaner, aligning with quality standards.
    • Enhanced stability: With less fat, the risk of rancidity during storage and transport is reduced.

  • Improve Safety

    • Longer shelf life: Less fat reduces microbial growth and contamination risk.
    • Lower toxic risks: Removing oxidized fats minimizes negative effects on animal health, such as reduced immunity or growth performance.
