ARROW MACHINERY Modified Starch Production Line for Food and Industrial Applications
ARROW MACHINERY designs modified starch process lines around twin-screw extrusion. Corn starch, potato starch, tapioca starch and wheat starch can be processed through controlled heat, pressure and shear to change the properties required by the final application. The line is suitable for starch manufacturers supplying food processing, papermaking, textiles, construction or pharmaceutical customers.
The process can be developed around low moisture extrusion and a selected starch recipe. Share the raw starch, target properties and required output so our engineers can recommend the right configuration.
For buyers comparing starch process lines, the modified starch production line combines food extruders, drying and size reduction in one coordinated process. The twin screw extruder working conditions are selected around the starch type, moisture target and required application result.
Product Description：
How the process works: the twin-screw extruder applies controlled temperature, pressure and shear to the starch. This changes the natural molecular structure and gives the material a more suitable response during later processing.
What can be adjusted: depending on the recipe and operating conditions, the process can be developed for gelatinization temperature, thermal viscosity, stability, gel strength and clarity.
Where the product is used: modified starch can serve as an auxiliary material in food processing, papermaking, textile production, construction materials and pharmaceutical applications.
Flow Chart
Raw Material and Mixing→ Extruding → Drying → Cooling → Crushing→Screening
Raw material and mixing: prepare the selected starch and water or recipe components for a stable feed.
Extruding: the twin-screw extruder works the starch under controlled heat, pressure and shear to develop the required modified properties.
Drying: reduce moisture to the level required for storage and downstream use.
Cooling: bring the dried material to a suitable temperature before size reduction.
Crushing and screening: reduce the material to the requested particle size and remove oversize particles for a more consistent final product.
A complete starch process line can be configured around the material, moisture target, particle size and required output.

FAQ
Q: What does twin-screw extrusion do in a modified starch line?
A: The current process description covers corn, potato, tapioca and wheat starch. The final recipe and equipment configuration should be confirmed through a material review or product trial.
Q: What does twin-screw extrusion do in a modified starch line?
A: The twin-screw extruder applies controlled heat, pressure and shear to change the starch structure and its processing properties. Temperature, moisture and screw conditions are adjusted around the target result.
Q: How does twin screw extruder working affect modified starch?
A: The twin screw extruder working conditions control heat, pressure, shear, residence time and moisture. These settings are matched to the starch recipe and the target gelatinization, viscosity, stability or clarity.
Q: What is low moisture extrusion in this application?
A: Low moisture extrusion uses a lower-water feed condition while the extruder supplies the heat and mechanical energy needed for processing. The suitable moisture level depends on the starch type and target properties.
Q: What is the capacity range?
A: The current reference models range from 250-450 kg/h to 1500-2000 kg/h. Final output depends on starch type, recipe, moisture target, required properties and operating conditions.
Q: How can I request a starch process line quotation?
A: Send the raw starch, application, target modified properties, capacity, moisture requirement, particle size and factory utility information. ARROW MACHINERY can then recommend a process route and quotation basis.
