Coffee Bean Moisture

Why Measure Moisture Content?

Processing coffee beans requires a reliable moisture measurement and control system to ensure the manufacturing process is not wasting product, time or energy. Very accurate coffee bean moisture levels have become a critical component during production of coffee because without close attention, the coffee bean moisture can easily become out of acceptable range. Are you properly monitoring coffee bean moisture?

With the help of industry partners and 40 years of knowledge, MoistTech has developed the IR-3000 coffee bean moisture sensor which is ideally suited to measure the coffee bean moisture levels in the coffee production process while improving manufactures product quality and lowering their energy costs.


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 & Dryer Efficiency

By installing the IR-3000 at the exit of the roasters as well as after grinding, a manufacturer can continuously monitor the process and can control the coffee bean moisture content either manually or automatically.

Another common application is to monitor the drying process for freeze dried and spray dried coffee. To accurately measure the coffee bean moisture levels, the sensor should be installed over the conveyor transporting the coffee or anywhere the coffee product can be viewed. The sensor should be mounted several inches above the belt, screw conveyor.

In certain applications, MoistTech can provide sampling systems which are designed for sanitary installations where it is difficult to monitor the product.

What is the Solution?

MoistTech has studied moisture and its applications in manufacturing for over 40 years. That’s why we’re confident our moisture analyzers are a step above the rest. We’re constantly working to develop the latest, most advanced moisture testing technology—which is how the IR-3000 came about.

We’ve combined our decades of experience and knowledge with feedback from our industry partners to create a moisture sensor capable of taking instant, non-contact measurements of moisture, temperature, and other vital levels with the utmost accuracy. When it comes to moisture sensors, the IR-3000 is the most advanced system available.


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.

Moisture Experts

Our specialized team of professionals at MoistTech are very experienced with the requirements in the production of coffee. Our sensor calibrations, measurement wavelengths, algorithms and sensor optical requirements are pre-set at the factory. Typical accuracy is about ±0.1% moisture and typical analog range is 0-10% moisture and up to as much as 40%, subject to application. The outputs can be adjusted to optimize PLC or recording requirements.

Understand the Process

Very accurate coffee bean moisture levels have become a critical component during production of coffee. Without close attention, the coffee bean can easily become either too wet or dry and wastes the processors’ time or money.
