RICE QUALITY AND PROCESSING Low - Temperature , Low - Relative Humidity Drying of Rough Rice

The use of low air temperatures (79 to 93 °F) and relative humidities (19% to 68%) to dry thin-layer samples of rough rice to the desired 12.5% moisture content was investigated. Drying rates and durations and their effects on the quality parameters of head rice yield, color, and pasting viscosity of longand medium-grain rice cultivars harvested at 19.6% and 17.5% moisture contents, respectivel...

Effect of Drying Temperature and Relative Humidity on Contraction Stress in Wood

As wood shrinks during the drying process, various stresses may develop and cause surface and internal checking. The aim of this study was to systematically investigate the effect of the drying temperature, relative humidity, and specimen thickness on the contraction stress in elm wood (Ulmus pumila L.) specimens during drying. The contraction stress was used as an indirect indicator of drying ...

Temperature and Relative Humidity Estimation and Prediction in the Tobacco Drying Process Using Artificial Neural Networks

This paper presents a system based on an Artificial Neural Network (ANN) for estimating and predicting environmental variables related to tobacco drying processes. This system has been validated with temperature and relative humidity data obtained from a real tobacco dryer with a Wireless Sensor Network (WSN). A fitting ANN was used to estimate temperature and relative humidity in different loc...
