Combining the benefits of photothermal conversion in a doped optical fiber with principle Fiber Bragg Grating (FBG)-based temperature measurement, new method for measurement moisture content has been developed and its performance is reported. This novel all-fiber approach shows important characteristics fast response, miniaturization design low power consumption. In this work, 1480nm pump laser...

the friction properties of granular materials play an important role in the determination of specifications for designing hoppers, transporting passages, dryers, silos and machines through which grain flows. in this study, the angle of repose and internal friction coefficient were determined for three common wheat varieties (sardary, gaspard and saysoter) at four moisture contents (12, 15, 18, ...

The response of a three-wavelength interdigital dielectrometry sensor to the moisture diffusion process in oil-impregnated transformer pressboard has been simulated using an empirical relationship between the moisture concentration and the dielectric properties of the pressboard. A benchmark test of the moisture diffusion process has been developed with the purpose of comparing alternative para...

We present FYMOS, an all-aluminum, robust, light weight, freeform based, near infrared hYperspectral imager for MOisture Sensing. FYMOS was designed and built to remotely measure moisture content using spectral features from 0.7-1.7µm integrating InGaAs sensor. The imaging system, operating at F/2.8, is based on the three-concentric-mirror (Offner) spectrograph configuration providing a resolut...

In this research, after conducting chemical tests on flour samples (moisture, ash, protein, fiber and pH), potato flour and xanthan gum were added to wheat four at levels 5, 10 and 15 percents and 0.5 and 1 percents, respectively, and subsequently production of toast bread in semi-industrial manner was started, Then the qualitative characteristics (Nutritional Value) of toast breads were measur...

The measurement of tea moisture content is important for processing and storing tea. The moisture content of tea affects the quality and durability of the product. Some electrical devices have been proposed to measure the moisture content of tea leaves but are not practical. Their performance is influenced by material density and packing. The official oven method is time-consuming. In this stud...

During cheese manufacture the moisture content of the curd must be carefully controlled. Curd moisture is usually measured by weighing and drying, which is a time consuming process. This paper describes progress in the development of microwave moisture sensing equipment suitable for the cheese industry. Results from a permittivity survey are described. A six-port network is evaluated for use as...
