Both cassava and potato starch are vital ingredient in food, pharmaceuticals, textiles, and biofuels. While they share similarities in their applications and processing procedure, their production processes differ significantly due to raw material properties and end-product requirements. This article will offer a comparison of cassava and potato starch production lines.

Cassava and potato starch production follow a similar framework:

cleaning-washing-grinding-separating-refining-dewatering-drying-sieving-packing, but machines in some processing stages are different.

Main Similarities Between Cassava and Potato Starch Production Lines

Cleaning: Raw materials are primarily cleaned by a dry sieve to remove dirt, stones, and debris.

Grinding: Both cassava and potato will be grind into mash by a cassava rasper

Separating: Cassava and potato starch slurry is extracted by a centrifugal sieve to remove fibers

Refining: Cassava and potato starch slurry is purified using hydrocyclone stations to remove proteins, cell and impurities.

Drying: Flash or airflow dryers produce a fine, dry starch powder.

Sieving: a sifter sieve helps to screen coarse starch granule and qualified starch powder.

Packaging: The final product is sieved, graded, and packed.

Key Differences Between Cassava and Potato Starch Production Lines

Washing: a paddle washer is often used in cassava starch production line to tail large stick-shape cassava tubers as well as removing part cassava peels; while a rotary washer is usually configured in the potato starch production line to wash small potatoes as well as reducing starch loss by avoiding the damage of potato peels.

Separating: in cassava starch production line, a fine fiber sieve is often added for further removing large and coarse fibers and ensuring starch taste due to the large fiber content in cassava tubers

Dewatering: in cassava starch production line, a peeler centrifuge is a common dewatering machine, which is suitable for fine starch granule production like cassava starch(its fineness is 5–35 µm), corn starch, and wheat starch etc. However, in potato starch(its fineness is15–100 µm) production line, a vacuum filter is more popular among clients for its cheaper advantage.
