Chavan et al. [127] studied the performance of a solar tunnel dryer that uses a conventional solar collector for drying 25 kg of Indian mackerel. The MC of this fish decreased to 16% (wb) from 72% The drying rate and drying efficiency were found 0.15 kg/hr. and 8.22 %, respectively in tunnel dryer and 0.02 kg/hr. and 3.38 %, respectively in open sun drying. The color and texture of the Indirect solar dryer can be used under forced convection mode for higher drying rates with better quality products. Jose & Joy [5] tested an indirect tunnel type solar dryer for the drying of turmeric under forced convection mode. The dryer took 25 h to attain the safe moisture content as compared to 46 h under traditional OSD. Net present value. 30,300.95. Benefit cost ratio. 1.06. Return of Investment. 21.60%. Drying components. The PHilMech’s MCSTD has three major componenets: the heat collector, drying chamber and fan/blower. The heat collector and drying chamber are covered with UV-stabilized polyethylene plastic sheets, mounted in inverted “V” metal frames. Length of solar tunnel dryer 21.0m Diameter of solar tunnel dryer 3.75m Floor area of solar tunnel dryer 78.75m2 Area of hemicylindrical shape of solar tunnel dryer 134.74m2 Height of north wall 1.57m The products dried with the help of solar dryers are having long life, test and aroma retention and fall in best quality. + Read More.

An environmentally friendly drying using Solar Tunnel Dryer (STD) is one of the techniques that is interestingly developed. The purpose of this study was to determine the effect of steam blanching at different times (3, 5, and 10 minutes) and soaking using a 0.05% citric acid for 5 minutes on the physicochemical and microbiological qualities of furZPq.
