Pretzel Moisture
Having the correct pretzel moisture level has become a critical component during the various stages of baking. The pretzel can easily become either too wet or too dry, wasting the manufacturer’s time and money as well as impacting the quality of the end product. With the help of industry partners and 40 years of knowledge, MoistTech has developed the IR-3000 moisture sensor that is ideally suited to measure the pretzel moisture levels during the baking process. The sensor is coated in a food grade Teflon with a polymeric viewing window enabling manufacturers to improve product quality without any contamination.
Installation
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. Ideally, a minute after the ovens. 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 in the finished product.
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.
Environment
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.
Benefits of Pretzel Moisture Control
- Improved Product Quality
- Lower Energy Costs
- Reduced Start-up Times
- Less Waste
- 100% Product Inspection

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.
