Research ArticleOpen accessIn the keywordsEvaluation of Energy Aspects of Apple Drying in the Hot-Air and Infrared DryersSeyed Hashem Samadi, Issa LoghmaniehDrying is an energy-intensive process. In general, heating and evaporation require large quantities of energy. This study has been conducted to evaluate analysis for dying apple slices in two drying systems including hot-air convection and infrared drying. The apple samples were dried at temperatures of 90, 120 and 150°C and radiation intensity of 0.22, 0.31 and 0.49 W/cm2 in the … …Energy Research Journal, Vol. 4, Issue 1 · 26 Aug 2013 · 8,009 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsThe Drying Kinetics of Chilies using a Rotating Fluidized Bed TechniqueWatcharin Dongbang, Worachest Pirompugd, Kittichai TriratanasirichaiProblem statements: The present study investigates experimentally the drying of chilies (Capsicum annuum L.) with rotating fluidized bed technique and the biological properties: capsaicin content, moisture diffusivity and activation energy. Approach: The drying experiment was conducted at the drying air temperatures ranged 70-120°C and the drying air velocity was fixed at 1.8 m sec-1, while the layer's height was fixed … …American Journal of Applied Sciences, Vol. 7, Issue 12 · 31 Dec 2010 · 7,425 accessesView PDF Cite

Research ArticleOpen accessIn the abstractExperimental Investigation of Thermo-Physical Properties of Soil Using Solarisation TechnologyAhmed Abed Gatea Al-Shammary, Abbas Kouzani, Akif Kaynak et al.Soil Thermo-Physical Properties (TPP) depend on heat transfer in the soil. This paper presents a study on different soil solarisation technologies influenced by soil TPP. This study evaluates three factors: The tillage depth for soil at three levels (15, 25 and 45 cm), the number of plastic film at three levels (single, double and without plastic film) and three cases … …American Journal of Applied Sciences, Vol. 14, Issue 7 · 17 Jul 2017 · 7,957 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMATHEMATICAL MODELING AND EXPERIMENTAL STUDY ON THIN LAYER HALOGEN DRYER OF STRAWBERRY AND STUDY IT’S EFFECT ON ANTIOXIDANT ACTIVITYAsaad Rehman Saeed Al-Hilphy, Ali Khudhair Jaber AlRikabiThe halogen drying characteristics of strawberry (Fragaria ananassa Duch) slices were investigated. Drying experiments were carried out a three different drying temperatures (60, 70 and 80°C). The effect of drying temperature on the drying rate, drying coefficient, efficiency, effective diffusivity of the strawberry and antioxidant activity were evaluated. The best model for describing the halogen drying process was chosen by … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 4 · 30 Sep 2013 · 7,367 accessesView PDF Cite
