Pregelatinized starch—also known as instant starch, α-starch, or pregel starch—is produced from native starch through high temperature, high pressure, and controlled moisture conditions. During processing, starch granules swell, hydrogen bonds break, and the molecules become fully hydrated before being rapidly dried into a porous, free-flowing powder.
It features rapid cold-water solubility, high viscosity, and excellent stability, making it widely used in food, feed, pharmaceuticals, construction materials, and industrial applications.
Drum Drying: Low investment but high energy use and limited control.
Spray Drying: High-quality powder but requires high cost and strict raw materials.
Twin-Screw Extrusion: Lowest energy consumption, no wastewater, high efficiency, excellent control of gelatinization, suitable for all starch types including high-amylose.
Advanced Extrusion Technology
Our twin-screw extruders ensure precise gelatinization, stable viscosity, and consistent product quality across various raw materials such as corn, cassava, potato, and pea starch.
Customized Turnkey Solutions
We offer full-line design, non-standard customization, and layout optimization based on your required capacity and automation level.
Energy-Efficient & Cost-Saving
Extrusion consumes significantly less energy and water compared with drum or spray drying, reducing long-term production cost.
