Coffee Bean Moisture

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.


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.


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.

Benefits of Coffee Bean Moisture Detection

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. 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.
