    New approach for thermal testing of solar dryer: Developmentof generalized drying characteristic curveShobhana Singh, Subodh Kumar⇑Centre for Energy Studies, Indian Institute of Technology, Delhi, IndiaReceived 19 December 2011; received in revised form 28 March 2012; accepted 2 April 2012Available online 3 May 2012Communicated by: Associate Editor I. FarkasAbstractIt is necessary to develop thermal test procedure that can assist performance comparison between various solar dryer designs on com-mon basis. In order to achieve this objective, the laboratory model of mixed-mode solar dryer is specially designed to perform indoordrying experiments with cylindrical potato samples. Sixteen drying kinetic curves are obtained over a wide range of various drying pro-cess variables. The variables investigated are absorbed thermal energy, air mass f l ow rate, food sample thickness and loading density.Based on experimental data of moisture content ratio-drying time, new concept to develop standard test method for performance eval-uation of a given dryer is proposed. The proposed methodology facilitates to generate single generalized characteristic curve representing16 drying kinetics and dimensionless parameter called dryer performance index (DPI) characterising the ef f ectiveness of dryer system isidentif i ed. Dif f erent solar dryers with potato, banana and wheat are also tested in real climatic conditions to validate the proposed meth-odology. DPI with consistent values for all test conditions, indicating high degree of independence of operating conditions and foodproduct characteristics, can therefore be used as a test parameter for performance comparison between dif f erent dryer designs on equi-table basis.? 2012 Elsevier Ltd.

IntroductionThe standard method for testing any equipment is nec-essary to provide guarantee of quality, safety and reliabilityto the ultimate customer. In addition, it helps in compari-son between two (or more) equipments under certain sim-ilar conditions, thus encouraging manufacturing industryto achieve competitive ef f i ciency and quality production.However, in order to develop reliable test method, severalrigorous performance evaluation experiments under varietyof test conditions are needed rather than single test donefor specif i c condition.Solar energy proves to be a promising alternative energysource in providing low grade heat required in many com-mercial and industrial applications, especially in countrieswhere this source is abundantly available. During pastthree decades, theoretical and experimental investigationsof various solar thermal systems have received considerableattention of researchers around the world with objectivesof reducing dependence on the energy sources derived fromfossil fuels and minimizing their adverse environmentalimpacts. The most widely studied solar thermal systemsinclude solar water and air heaters, box and focussing typesolar cookers, solar dryers, and solar stills. It can benoticed that the thermal test procedures for standardiza-tion of selective solar equipments namely, solar domesticwater heaters, solar cookers, etc., have already been devel-oped and adopted in many countries including India0038-092X/$ - see front matter ? 2012 Elsevier Ltd.
