Broader raw material adaptability: It can process ingredients with high or low viscosity, high oil or moisture content, or those that are sticky, oily, or very wet—materials that would typically cause slippage in a single-screw extruder (SSE).

Fewer restrictions on raw material particle size: It can handle a wide range of particle sizes, from fine powders to coarse granules, including materials that fall outside the specific size ranges suitable for single-screw extrusion.

More uniform material flow within the barrel: This ensures consistent distribution of additives—such as steam, water, or other processing aids—to achieve the desired final product characteristics.

Superior internal and external product quality: It achieves a high degree of homogenization, resulting in a uniform molecular structure. This leads to a smooth surface upon extrusion, highly consistent particle size, and excellent overall uniformity.

Enhanced cooking and homogenization: Starch gelatinization levels can typically exceed 95%, ensuring that the resulting aquatic feed remains stable in water, retains its nutritional content, and is easily digested and absorbed.

Higher throughput for the same power input: Excellent mixing capabilities ensure that heat is rapidly and evenly distributed throughout the material, accelerating the cooking process, minimizing fluctuations in material temperature, and increasing the output of extruded products.

Greater product diversity and versatility: It can produce a wide array of items, including micro-pelleted aquatic feeds, high-oil or high-moisture formulations, highly cohesive products, multi-colored items, filled (co-extruded) products, and complex, custom-shaped goods.

Simplified operation: The main shaft speed can be adjusted to meet specific product requirements. Furthermore, the self-cleaning nature of the system makes maintenance easy, eliminating the need to disassemble the equipment after each production run.

Reduced wear on consumable parts: Contrary to the common misconception that single-screw extruders experience less wear, twin-screw extruders actually cause less abrasion to the screws and barrel liners. This is due to more stable material transport and flow characteristics. Even though there are more screws involved, the overall cost of replacement parts remains lower than that of a single-screw system. 10. Lower production costs: Thanks to the excellent operational stability of twin-screw extruders, the feed processing workflow benefits from reduced material waste during startup, minimal loss of water and steam, lower labor costs, high heat-transfer efficiency, high product yield, and superior output per unit of electricity consumed. Furthermore, with lower costs for spare parts, the overall production cost remains significantly lower compared to that of single-screw extruders.
