Abstract 

The system presented estimates moisture in green coffee during drying process using two methods, which were capacitive sensors and mechanical load detection, to estimate it. Results show it is possible to determine coffee grains moisture from 40 to 10% humidity range, either by dielectric measurements, with a developed sensor, or dryer mechanical load, making it possible to get better storage conditions for coffee beans.
