    (Wiley, 2021-06-27) D. S. Aniesrani Delfiya; K. Prashob; S. Murali; P. V. Alfiya; Manoj P. Samuel; R. Pandiselvam
    In recent years, many infrared (IR) and IR-assisted drying methods such as IR-hot air, IRvacuum, IR-microwave, and vibration aided IR-dryer have been reported for drying of food materials due to its rapid drying behavior and less processing time due to high drying rate, consumes less energy, offers better control over temperature, superior quality products, less ecological footprint and also easily it can be combined with other modes of heating technologies. The combination of IR radiation with other drying methods is very promising as it not only improves the drying rate but also preserve the food quality. IR and IR-assisted drying have been proved as a potential drying method for many food products. Drying kinetics of food materials during IR drying is very critical for the design of IR dryer, selection of appropriate drying parameters, product quality maintenance, and control and optimization of the drying process. Therefore, this paper aims to report the optimum process parameters for IR and IR-assisted drying of food materials and its drying kinetics. Similarly, critically reviewed the effect of various factors on the IR drying process such as drying rate, specific energy consumption, effective moisture diffusivity, and activation energy during drying of various food materials.

    Hot air-assisted continuous infrared dryer for anchovy fish drying
    (Wiley, 2021-07-17) D. S. Aniesrani Delfiya
    This study was performed to assess the application of a hot air-assisted continuous infrared dryer for anchovy drying and to examine the drying characteristics of small- and large-sized anchovy fish. Experiments were carried out at the infrared radiation intensities of 1,000, 2,000, 3,000 W/m2 and IR source-sample distances of 5, 10, 15 cm. The impact of IR intensity and distance between the IR source and sample on moisture content, drying efficiency, drying time, specific energy consumption, water activity, rehydration ratio, shrinkage, and surface color change were evaluated using statistical analysis. The most efficient drying parameters were observed at 2,000 W/m2, 10 cm, and 2,000 W/m2, 5 cm for small and large anchovy fish, respectively, based on the drying and quality characteristics of dried anchovy fish. This study ensured the potential application of a hot air-assisted infrared drying system to acquire dried anchovy fish with increased shelf life.
