Prediction of corn and lentil moisture content using dielectric properties
نویسندگان
چکیده
Almost all properties of grains and seeds depend on moisture content. One of these properties is dielectric constant. Therefore capacitive sensor is used in precision agriculture widely. In this paper, a cylindrical capacitor was used to measure dielectric constant of seed. By measuring the dielectric constant, the moisture content of grains may be predicted. Change in dielectric constant of corn and lentil was investigated as a function of moisture content. Results showed that dielectric constant is highly depended on moisture content at all frequencies. The best results obtained at 100 kHz frequency and 500 kHz for corn and lentil with R of 0.993 and 0.996 respectively. These frequencies may be used to calibrate the instrument for measuring the moisture content of corn and lentil.

Corn Moisture Measurement using a Capacitive Sensor
Corn moisture content is the main factor of effecting corn safe transportation and storage, and is also an indispensable measurement part when it is used to feed, food and industry. Due to large particle size, corn will produce large gap during measuring moisture content. Because air has much influence on dielectric constant of the device, moisture content is not precision. In all kinds of corn...

متن کاملMechanical damage to green and red lentil seeds
In this research, the breakage susceptibility of two classes of lentil (green and red) was evaluated as affected by impact energy and seed moisture content. The experiments were conducted at impact energies of 0.1, 0.2 and 0.3 J, and moisture contents of 10, 12.5, 15, 17.5, 20 and 25% (wet basis). Results showed that red lentil seeds had more breakage than green seeds and the difference in brea...
