This work centered on the effects of the moisture content, slices thickness and microwave power on aspects of energy and exergy, drying kinetics, moisture diffusivity, activation energy, and modeling of the thin layer drying of kiwi slices. dampness content. Even though Midilli model showed the best match, Webpages model was selected, since it experienced almost a similar performance but the model is simpler with two guidelines instead of four. Keywords: Energy, Exergy, Modeling, Microwave drying, Dampness diffusivity, Kiwi slices Introduction Kiwifruits have very short shelf-life because of softening and vitamin loss during storage actually Trichostatin-A at refrigerated conditions (Mohammadi et al. 2008; Dalvand et al. 2013). New kiwifruits are usually dehydrated to extend their shelf existence and, therefore, can provide a good alternative to fresh fruits, permitting the availability of out of time of year fruits (Maskan 2001; Doymaz 2008). The drying kinetics of food is a complex phenomenon and requires simple representations to forecast the drying behavior, and for optimizing the drying parameters. Drying is the most energy intensive process in the food industry. One of the important issues of drying out technology is to lessen the expense of energy resources to improve the performance of drying out facilities for an excellent quality of dried out items (Doymaz 2011; Darvishi et al. 2014a; Alibas 2007). Because of the high prices of energy, environmental problems as acid rainfall and stratospheric ozone depletion, global warming, elevated world people and lowering fossil gasoline recourses, the ideal program of energy as well as the energy intake management strategies are vital. In the thermodynamics viewpoint, exergy analysis provides were an essential device for system style, analysis and marketing of heat systems (Prommas et al. 2010, Dincer and Trichostatin-A Sahin 2004). Exergy is normally defined as the utmost amount of function which may be made by a blast of matter, high temperature or are it involves equilibrium using a guide environment (Akpinar et al. 2005; Dincer 2002). The exergy technique might Trichostatin-A help additional the purpose of better energy reference make use of as the places are allowed because of it, types and accurate magnitudes of loss to become driven (Liu Trichostatin-A et al. 2008, Prommas et al. 2012). Convective drying out in heat is still typically the most popular technique applied to decrease the wetness content of vegetables & fruits. Nevertheless, this technique includes a accurate variety of drawbacks such as for example extremely long-lasting drying out period, high energy intake, contamination complications, low energy performance and high costs which isn’t a desirable circumstance for the meals sector (Alibas 2007; Dadali and Ozbek 2007, Al-Harahsheh et al. 2009). The desire to lessen the above complications, as well concerning obtain fast and effective thermal procedure lead to the usage of microwave and dielectric heating system method for meals drying out (Bondaruk et al. 2007; Orsat et al. 2007). Microwave drying out has many advantages such as for example higher drying out rate, shorter drying out time, lower energy usage, and better quality of the dried products (Sarimeseli 2011; Wang et al. 2007; Soysal et al. 2006). An important aspect of developing drying technology is the mathematical modeling of the drying processes and products. Accurate modeling allows design engineers to choose the most suitable operating conditions and then size the drying equipment and drying chamber accordingly to meet the desired operating conditions (Darvishi et al. 2014a; Al-Harahsheh et al. 2009). The main transport property integrated in most drying Rabbit polyclonal to Hsp22 models is effective dampness diffusivity (McMinn et al. 2003; Haghi and Amanifard 2008). Knowledge of accurate Dem is very important for modeling.
