Potato Chip Moisture

Immediate Process Improvements

Moisture and oil measurement is an essential step in the manufacturing process of potato chips and other common snack foods. Process operators need to ensure the quality and consistency of the product in order to eliminate waste and increase plant efficiencies. Potato chip moisture can play a major role in the end product quality. The best solution is a near-infrared moisture detection system mounted directly on the production line.

MoistTech’s IR3000-F sensor is ideal for the processing areas of potato chips to properly measure and manage moisture and oil contents on a continuous basis. The technology delivers hundreds of data points per second to allow the operator fuill control over the manufacturing process.

The sensor is coated in a food grade material with a polymer optical window allowing manufacturers to improve product quality and monitor moisture continuously.

Measure Moisture in Real Time

Unsurpassed in performance, our sensors can accurately measure  moisture within tenths of a percent of most applications


MoistTech sensors withstand the test of time and are low to zero maintenance


Rely on MoistTech’s NIR moisture sensors to never drift or need re-calibration


A moisture measurement system is essential for the production process and in some cases will pay for itself in less than 30 days

Installation Tips

Ideally, the moisture sensor should be installed after the fryer outlet. and should be mounted several inches above the vibrating conveyor so that it can continuously monitor the process and can control the potato chip oil and moisture content levels either manually or automatically in the finished product.

If the sensor must be installed close to the outlet of the fryer and will be susceptible to extreme heat conditions, it is necessary to cool the sensor with either air or water. Furthermore, if the sensor is located near an oil spray, it is necessary to clean the sensor’s optical window during regular routine cleaning.

Efficiency is a top of the line priority for manufacturers and the dryer can drain a lot of that. Measuring the moisture before and after the dryer allows the user to optimize the dryer settings to save time and money. A proper moisture control system will pay for itself with the energy savings from the dryer in less than 30 days. Efficiently controlling the dryer within the facility can drastically change the productivity levels.

What is the Solution?

The MoistTech team of professionals are very experienced with the requirements in the production of potato chips and other snack foods. Our sensor calibrations, measurement wavelengths, algorithms and sensor optical requirements are pre-set at the factory based upon your specific product. Typical accuracy is about ±0.1% moisture and ±0.2% for oil and Typical analog range is 0-5% for moisture and 20-40% for oil.
