Two Production Mistakes Killing Your Cassava Flour Fineness Pass Rate

Among all the reasons cassava flour gets rejected, fineness ranks first. Yet most producers cannot accurately state what the standard actually is — or where the problems in their production line are really coming from.

This video breaks down the HQCF fineness standard in full: 95% passing through a 60-mesh sieve. It also goes deeper into the two mistakes most producers make that kill their fineness pass rate.

Mistake 1 - The grinding stage. Insufficient crushing leaves the mash with chunks larger than a grain of rice. Over-processing turns it into a smooth paste. Either scenario causes trouble downstream.

Mistake 2 - The sieving stage. A proper sifter separates on-spec material from off-spec particles. But many operations rely on a single screen deck with the same mesh for every batch and no recycle loop. The result: fineness varies from batch to batch, and customers start returning the flour.

The right equipment combination can push a pass rate from 80% all the way to 99%. Follow Henan Jinrui — we can customize the right cassava flour processing equipment to meet your specific needs.
