Industrial Potato Washing System for a French Fry Production Line — learn how Yuerui Machinery supports your production with reliable equipment and engineering.

A french fry producer in Inner Mongolia was washing 5 tons of potatoes per hour through a 20-year-old drum washer. Sand and skin contamination was running at 15% on washed potatoes, which meant extra knife work on the peeling line and frequent customer complaints about grit in the final fry.

The Challenge

The producer needed a washer that would lift clean-stock to at least 99%, handle the 5 tons/hour rate without bottlenecking the peeling line, and use less water (the old drum needed 12 m³ of fresh water per hour). Floor drainage was also constrained, so the new machine had to be self-contained.

The Solution

We installed an industrial potato washing machine with food-grade nylon brush rollers, a recirculating water system, and a spray-bar manifold. The whole unit sits in a sealed stainless pan that drains to the existing sediment trap, with no extra civils work.
