Integrated Solution for Modified & Pregelatinized Starch Production

Advanced Twin-Screw Extrusion System for Functional Starch Processing

Jinan Saixin Machinery Co., Ltd. provides a high-performance Modified Starch and Pregelatinized Starch Production Line designed for the efficient processing of corn starch, cassava starch, potato starch, and other industrial starch materials. Using advanced twin-screw extrusion technology, the system transforms raw starch into a gelatinized, thermoplastic, and partially α-structured modified starch, delivering excellent solubility, improved functionality, and enhanced processing performance.This production line is widely used across multiple industries, including construction materials, textile manufacturing, food processing, pharmaceutical excipients, oil drilling, adhesives, and paper production, making it a versatile and high-value industrial solution.

Complete Modified Starch Production Process

The automatic starch processing line includes the following stages:

1. Raw Material Mixing

Corn starch, cassava starch, potato starch, and other raw materials are precisely blended for uniform processing consistency.

2. High-Temperature Extrusion

The twin-screw extruder applies heat, pressure, and shear force to modify starch structure into a gelatinized thermoplastic state.

3. Multi-Stage Drying

Controlled drying removes moisture while maintaining the functional properties of the modified starch.

4. Step-by-Step Cooling

The material is gradually cooled to stabilize structure and prevent agglomeration.

5. Fine Grinding

The processed starch is milled into fine powder form suitable for industrial applications.

6. Final Storage & Packaging

The finished modified starch is stored or packaged for transportation and industrial use.

Wide Range of Applications

The produced pregelatinized and modified starch is widely used in:

• Construction materials (plasters, mortars, additives)

• Textile sizing and finishing

• Food industry (thickening, stabilizing agents)

• Pharmaceutical excipients

• Oil drilling fluids

• Paper manufacturing

• Adhesives and coatings

• Biodegradable materials

Its excellent solubility, stability, and binding properties make it a critical raw material across multiple industries.
