How to process | Potato starch

Processing potato starch | the challenge

Potato starch is a fine, lightweight powder with a relatively low bulk density and a tendency to create dust. Depending on moisture content and processing conditions, it can become cohesive or prone to bridging, leading to inconsistent flow. 

If equipment is not designed to accommodate these properties, issues such as build‑up, irregular feeding, dust emissions, and reduced throughput can occur, directly impacting production performance.

Why potato starch is difficult to handle | hygiene control

In food applications, maintaining product purity is essential. Potato starch is widely used in food processing, where even minimal contamination from worn components, unsuitable materials, or poor sealing can compromise product safety and quality. 

Hygiene standards are strict, meaning that the rotary valve must not only perform reliably but also support easy cleaning and, where required, comply with food‑grade certifications.

The role of the rotary valve

Rotary valves designed for potato starch applications emphasise smooth internal finishes, tight tolerances, and materials suitable for hygienic use.

Features such as stainless steel parts, minimised dead zones, and dust‑tight sealing solutions help maintain product integrity while ensuring controlled, consistent flow.

Proper configuration is crucial, whether the valve is used for dosing, pneumatic conveying, or as a protective system. 

Optimal potato starch flow | the result

When potato starch flows smoothly and hygienic conditions are maintained, operations benefit from consistent product quality, reduced cleaning downtime, and improved overall efficiency.
