Cassava Flour Rejection: The 60 Mesh 95% Passing Standard

Fineness inconsistency is the leading cause of cassava flour rejection worldwide — yet many producers don't know what the international standard actually requires.

This short video breaks down the HQCF fineness standard (95% passing 60 mesh) and explains why so many processors fail to meet it consistently.

It also walks through the two most common failure points in production — the grinding stage and the sieving stage — and shows how simple equipment issues at either stage can lead to batch-to-batch inconsistency and costly customer returns.

Watch the full video for a clear explanation of what the standard is, where most processors go wrong, and what needs to change to fix it.
