Última Frequency, moisture content, bulk density and hybrid effects on grain sorghum dielectric properties 111 Moura, Eros Estevão; Berbert, Pedro Amorim; Souza, Elias Fernandes; Garcia, Ricardo Ferreira; Molina, Marilia Amorim; Oliveira, Marcia Ramos. The interest in the dielectric properties of grains has been increasing over the years due to their potential utilization in advanced technologies such as the density-independent on-line estimation of moisture content in automatic control processes in grain drying operations. A capacitive sensor was used with a LCR meter to obtain a better understanding of the variation of relative permittivity and dielectric loss factor of four hybrids of grain sorghum in the frequency range from 75 kHz to 5 MHz, at 23°C and 62% relative humidity. Curves that are presented illustrate the variation of these dielectric properties on moisture content (7% to 23% w.b.), bulk density (575 to 819 kg/m3) and hybrid. The obtained results should provide a firm basis for future...

Ano: 2016 URL: http://www.cigrjournal.org/index.php/Ejounral/article/view/3027 DEVELOPMENT OF A LOW COST SUGARCANE HARVESTER PROTOTYPE 107 Garcia, Ricardo Ferreira; Vasconcelos Junior, José Francisco Sá. A prototype of sugarcane harvester driven by a small tractor with the ability to cut and drop the stalks to the ground was the development and evaluated. The prototype moves toward the line to be harvested, and the sugarcane stalks are conducted by dividing lines and the chassis structure, cutting the stalks with their cutting blades mounted on a disc. A conveyor system is responsible for lateral movement and overturning of the cut stalks. Some machine structural problems and land irregularities affecting operational performance were found in field tests. The results demonstrated that certain modifications should be carried out on the prototype for improvements in its operating system, especially in the lateral and overturning operations, where part of the...
