Microwaves to measure moisture in coffee

Tews Elektronik provides a range of instruments based on its patented microwave resonance technology which can accurately measure moisture in the product at every stage of the process

In order to produce a finished product whose moisture content lies within strict levels, it is necessary to monitor and control moisture throughout the coffee manufacturing process.

Measurement is unaffected by colour, grain size or surface structure and so is equally effective on whole beans or ground coffee.

Core moisture is measured, not just surface moisture and results are instantaneous without the need for heating or grinding.

In Germany, Tews reports that it has worked closely with a leading supermarket chain and Probat, the major manufacturer of coffee roasting machines, with great success.

Neumann Coffee use Tews instruments to measure the moisture in green beans at-line and in the laboratory.

Because the Tews technology measures density as well as moisture, the MW3200 has also been used effectively at the packing stage to optimise filling quality.

Whether you require an instrument for the laboratory, to be used at-line, or to be installed in-line, Tews says it has a system that can give you fast, accurate results, and help you deliver a perfect product.
