Extrusion Technologies
Extrusion technologies use mechanical energy, heat, and moisture to transform raw protein materials into structured food products. Twin-screw and single-screw extruders are the workhorses of the plant-based meat industry, producing both textured vegetable protein (TVP) and high-moisture meat analogues (HMMA). Modern extrusion lines can achieve throughputs of several tons per hour.
Process Overview
- 1Raw Material Preparation: Blend and condition protein powders
- 2Feeding: Introduce mixture into extruder barrel
- 3Cooking & Texturizing: Apply heat, pressure, and shear
- 4Shaping: Form product through die and cooling die
- 5Post-processing: Cut, dry, or further process
