Popcorn Sprayed with Oil & Flavorings

Product Quality

Maintaining a close monitor on the oil and flavorings of popcorn not only gives improved product quality, but also produces lower energy costs, reduced start-up times, less product waste, 100% product inspection, and less downtime.

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


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 Efficiency

Installation of the sensor after the sprayer, will allow the measurement of oil and flavoring on the popcorn to be properly measured and controlled. The sensor should be installed several inches above the belt or screw conveyor so that a production worker can continuously monitor the process and can control the oil and flavoring content either manually or automatically in the finished product.

If the popcorn has 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 is located near an oil spray, it is necessary to clean the sensor’s optical window during regular routine cleaning. If the oil or flavoring sensor has to be installed where it will be susceptible to extreme heat conditions, it is necessary to cool the sensor with either air or water.

What is the Solution?

MoistTech is very experienced with the requirements in the production of popcorn and snack foods, developing one of the most accurate oil sensors, the IR3000-F sensor is ideally suited to measure the oil and flavorings sprayed on popcorn during the manufacturing process.

The sensor is coated in a food grade Teflon with a polymeric viewing window enabling manufacturers to improve product quality without any contamination. In addition to oil testing, the state-of-the-art senor takes instant, accurate, non-contact measurements of temperature, seasonings, moisture, fat, sugar, protein, and more.


Locate the point in the production process in which measuring moisture will be the most crucial and beneficial. Identify how you will use the moisture measurement data for improvements and if it will tie into your PLC.

Remember this could involve more than one installation point!


A closed loop process is achieved by incorporating a moisture measurement system into the manufacturing process. Developing a proactive solution to moisture control will avoid costly downfalls. 


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

Using the IR-3000 drastically cuts production costs. It is energy efficient, low maintenance, and decreases startup and down times. Over dried product causes waste; so does product that is too moist. With the IR-3000, these problems will no longer be an issue.

Using the IR-3000, you’ll save money throughout the entire production process, while making the best quality product at the same time. With MoistTech, you don’t need to compromise.
