The centrifuge sieve (also called centrifugal sieve or rotating sieve) is a key piece of equipment in the potato starch purification line. It plays a crucial role in separating fine starch from fibrous pulp and other impurities. Below are its functions and advantages:

Functions of Centrifuge Sieve in Potato Starch Purification Line

Primary Fiber Separation：Removes coarse potato fibers and pulp from starch slurry after rasping and extraction. Acts as the first filtration step to separate starch milk from residual potato solids.

Fine Starch Recovery: Captures fine potato starch particles that pass through earlier screening stages.Improves potato starch yield by preventing loss with the pulp.

Washing and Dewatering: Uses centrifugal force to wash potato starch slurry, removing soluble impurities. Reduces water content in the extracted starch milk before further refining.

Multi-Stage Filtration: Often used in multiple stages (e.g., primary, secondary, and tertiary sieving) for progressive potato starch purification.Each stage refines starch slurry further by removing smaller impurities.

Advantages of Centrifuge Sieve

✔ High Efficiency – Centrifugal force enhances separation speed, improving processing capacity.

✔ Improved Starch Quality – Effectively removes fine fibers, ensuring smoother potato starch slurry.

✔ Water & Energy Savings – Requires less wash water compared to traditional vibrating sieves.

✔ Compact & Low Maintenance – Fewer moving parts than vibrating screens, reducing wear.

✔ Adaptability – Adjustable sieve mesh sizes (typically 50–150 microns) for different purification stages.

✔ Continuous Operation – Suitable for large-scale, automated potato starch production lines.

The centrifuge sieve is essential purification equipment for high-yield and high-quality potato starch production, efficiently separating starch from fibers while minimizing losses.
