Potato Chip Moisture

HEB TORTILLA #2The correct potato chip moisture level is a critical component during the various stages of production and frying.

Chips and other snack foods can easily become either too wet or dry and/or oily wasting manufacturer’s time and money as well as impacting the quality of the end product.

With the help of our industry partners and together with our 40 years of knowledge and experience, your MoistTech team has uniquely developed the IR-3000 Potato Chip Moisture Sensor that is ideally suited to measure both the potato chip moisture and oil levels during the baking and frying 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.


Ideally, the IR-3000 potato chip moisture sensor should be installed after the fryer outlet. It 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.

Your 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. Typical accuracy is about ±0.1% moisture and ±0.2% for oil. Typical analog range is 0-5% for moisture and 20-40% for oil.
