Pretzel Moisture

Consistent Benefits of 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.

  • Redcue Dryer Usage and Energy Costs
  • Proper Control of the Infeed & Dryer Exit
  • Better Quality Final Products
  • Consistency
  • 100% Product Inspection

Compare MoistTech to Competition

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.

The production of hard pretzels involves a heat/alkali treatment and subsequent baking and drying to a final moisture content of 2%.


Our equipment never comes into contact with the product, allowing for less waste

zero drift

Our sensors are guaranteed not to drift over time – which saves time and money

closed loop

Create a closed-loop process by tying a moisture sensor into your PLC. Full control over the line!

no recalibrations

We’ve mastered the art of moisture sensors – your unit will never need to be recalibrated for the same product twice!

Sensor Installation

By installing the MoistTech pretzel moisture sensor at the exit of the ovens, close to the packaging, will allow the pretzel’s 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’s experts will assess your specific application with lab tests, calibrations and accuracy results to ensure our equipment will peform for you. All of our sensors are pre-calibrated prior to being shipped to create a plug-and-play operation for the end-user.

Understand the Process

During pretzel manufacturing, it is important to know the moisture content after the oven outlet as they can affect quality and consistency, as well as the taste, appearance, stability, and shelf life.
