Conventional methods are limited to specific time points during the production. Every measurement depends on the sampling and operator leading to variations of 2% and more. The MicroDry monitors continuously without the need of an operator significantly improving the accuracy.
In contrast to conventional methods, the Moisture-Sense is based on microwave technology allowing to measure volumes of bulk material. The microwaves travel from the transmitter (Tx) to the receiver (Rx) measuring the moisture or dry matter over a large volume of French fries. This averages variations between fries providing reliable measurements.
