Frequently Asked Questions

Everything you need to know about our puff snack extrusion lines

Corn grits and abrasive starches generate extreme wear during high-shear extrusion. Our screws are fabricated from premium 38CrMoAl alloy steel and undergo precise plasma nitriding, yielding a surface hardness of ≥HV850 and a case depth of 0.5–0.8mm. This robust metallurgy ensures over 8,000 hours of continuous wear life, protecting your Overall Equipment Effectiveness (OEE) and minimizing batch-to-batch structural variance.
We achieve this through our modular co-rotating twin-screw configuration and multi-zone independent heating. By precisely modulating the Specific Mechanical Energy (SME) and steam-flashing pressure at the die face, our PLC-controlled systems guarantee that the starch matrix is fully plasticized, yielding uniform density, optimal pore expansion, and consistent texture in every shape.
Yes. The line is engineered as a highly modular ecosystem. To switch from standard puffs to premium core-filled rice bites, you simply inline our ZHYX-I automated core-filling machine (which injects the chocolate, cream, or peanut butter slurry directly into the extruded tube prior to cutting) and add a multi-functional shaper/pulling cutter at the extruder exit.
Fast high-temperature roasting causes the starch cell wall structure to shrink unevenly, which creates high internal stress and leads to snack fragility. Our multi-layer belt dryers use continuous hot air recirculating convection. By slowly and uniformly extracting moisture from the core outward, it preserves the delicate cellular structures, yielding a crispier bite, reducing oil absorption, and extending product shelf-life.
To guarantee continuous, fail-safe 24/7 industrial performance, we standardly equip our lines with Siemens (China) main motors, Delta or ABB variable frequency inverters, ABB or Schneider contactors and relays, and NSK heavy-duty bearings. This premium matrix ensures stable torque output under fluctuating utility voltages.
We provide full turnkey global support. We dispatch senior mechanical and electrical field engineers directly to your site for on-site machinery assembly, piping/cabling coordination, line calibration, formula fine-tuning (using local raw starches), and comprehensive operator training on preventative maintenance.
