Frequently Asked Questions

Everything you need to know about our modified starch extrusion lines

Traditional starch modification relies on wet chemical reactors that require huge building footprints, massive fresh water consumption, and generate toxic chemical wastewater. Zhuoheng’s reactive twin-screw extrusion operates as a continuous, zero-effluent process. It combines mechanical shearing, thermal melting, and chemical reagents inside the barrel in a single step, reducing energy consumption by 40% and cutting wastewater discharge by up to 80% while ensuring uniform chemical substitution.
Yes, absolutely. By optimizing the Specific Mechanical Energy (SME) inputs and introducing chemical cross-linking agents during the twin-screw reactive extrusion process, our lines produce high-quality cross-linked starch that can withstand extreme bottom-hole temperatures up to 160°C–180°C under high-pressure (HPHT) environments. The resulting product completely complies with API Spec 13A Section 10 standards for fluid loss control in water-based drilling muds.
Starch modification often involves acidic or alkaline chemical reagents that accelerate wear and chemical corrosion. We manufacture our screws and barrels from premium 38CrMoAl alloy steel treated with a deep nitrogen gas nitriding process, achieving a surface hardness of ≥HV850 and a case depth of 0.5–0.8mm. For highly corrosive formulations, we offer bimetallic barrel liners with nickel-based alloys to extend the screw lifecycle to over 300 days of continuous operation.
Our extruders feature long length-to-diameter (L/D) ratios of up to 44:1, providing sufficient residence time for thorough molecular cleavage and uniform chemical blending. Working in combination with high-precision PID temperature control (fluctuation within ±1°C), the system ensures a starch gelatinization degree of ≥90%, resulting in extremely stable cold-water viscosity and excellent batch-to-batch uniformity.
Absolutely. This turnkey system is designed with a modular screw and barrel configuration. By swapping the screw element arrangement and updating the PLC temperature profile, you can easily switch production from industrial-grade oil-drilling starch to food-grade pre-gelatinized starch used as premium thickeners and stabilizers in the food processing industry.
Yes, we provide full turnkey support. Along with our machinery, we supply starter chemical formulations for pre-gelatinized and drilling-grade starches. Our senior field engineers will travel to your site to handle machinery installation, piping/wiring coordination, system calibration, trial runs using your local starch, and operator training.
