Extruder machine

The global pet food market is growing at an annual rate of 11.3%, fuelling strong demand for high‑performance dog food extrusion equipment. The pet food extrusion equipment market is projected to reach US$3.63 billion by 2033. Twin‑screw extrusion technology is replacing single‑screw processes due to its superior material adaptability, mixing homogeneity, and stability, especially for high‑fresh‑meat recipes. Jinan Bright Machinery Equipment Co., Ltd., a Chinese manufacturer established in 2012, offers DSE series twin‑screw extruders with capacities from 100 to 5,000 kg/h, supporting 20‑40% animal protein inclusion and various pellet shapes. The company provides complete production lines, holds ISO 9001 and CE certifications, and exports worldwide. It is committed to innovation and quality to support the global pet food industry’s upgrade.

This article introduces plant-based shredded protein, a fibrous ingredient made from plant proteins via extrusion, with high protein content and versatile applications in vegetarian foods, meat products, and frozen items. The market is growing rapidly, with production reaching 280,000 tons in 2023 and a projected CAGR of over 25% through 2028. Production relies on twin‑screw extrusion lines. The article then highlights Jinan Brihgt Machinery Equipment Co., Ltd., a Chinese manufacturer specializing in extrusion equipment. The company offers complete shredded protein production lines (DSE85‑S series) with efficient drying and cooling systems, as well as various other food processing lines. Its equipment is exported to over 20 countries. The article concludes that Chinese equipment makers are playing a key role in supporting the sustainable development of the plant‑based protein industry.

This analysis highlights the core differences between Soy Textured Vegetable Protein (TVP) and Soy Fibrous Protein (SFP). TVP uses simple defatted soybean meal, low-moisture extrusion, and forms a random porous structure, suitable for cost-effective meat filling and pet feed applications. SFP, made with soy isolate and gluten, uses high-moisture high-shear directional extrusion to create aligned muscle-like fibers, delivering superior rehydration, chewiness, and integrity, making it ideal for premium plant-based meat substitutes. The distinct raw materials, processes, internal structures, and end-uses necessitate tailored production line configurations, and the company offers customized solutions for both product types.
