Pretzel Moisture


Benefits of Pretzel Moisture Control

Various stages of baking pretzels require proper moisture measurement and control. Pretzels can easily contain too much or too little moisture which wastes the manufacturer’s time and money as well as impacts the quality of the final product.

MoistTech’s sensor is coated in a food grade Teflon with a polymeric viewing window enabling manufacturers to improve product quality without any contamination.

By installing the MoistTech pretzel moisture sensor at the exit of the ovens, close to packaging, will allow the pretzels time to stabilize while cooling. The sensor should be installed several inches above the belt or screw conveyor so that a baker can continuously monitor the process and can control the moisture content either manually or automatically.

If the pretzels have gone through an oil spray, it is important to install the sensor at an angle to cut down any reflection from the oil coating.

If the sensor has to be installed close to the oven outlet where it 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.


MoistTech is very experienced with the requirements in the production of pretzels and 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. Typical analog range is 0-10% moisture. The outputs can be adjusted to optimize PLC or recording requirements.
