Description A study was conducted to evaluate performance evaluation of solar tunnel dryer for
round the year use. In the present study, performance of solar tunnel dryer was evaluated at
no load and at full load conditions. Full loading was done with garlic, chilli, fenugreek and
aonla candy according to their seasonal availabilit y in Hisar. At no load performance was
evaluated during three seasonsi.e summer, winter and autumn. At full load conditions
moisture content versus time and drying rate versus moisture content relationships were
determined. The drier reduces the moisture content of garlic from 63% to 70% (w.b.) to the
required moisture level of 9% to 10 % (w.b.) in 8 t o 10 days and average thermal efficiency
of drier was estimated to be 14.53%. Treatments were given to garlic and their effect on
drying days were studied and results show that there were no significant difference in time
of drying. During drying of chilli it was found that the chilli can be dried from an initial
moisture content of 77% to 79% (w.b.) to the final moisture level of 7% (w.b.) in 6 to 7
days and average thermal efficiency was estimated to be 14.33%. In case of drying of
fenugreek, during the month of January it was found that the fenugreek can be dried from
an initial moisture content of 86% (w.b.) to 7.2% ( w.b.) in 5 days and average thermal
efficiency of drier was estimated to be 17.63%. Similarly during drying of aonla candy, it
was found that the aonla candy can be dried from aninitial moisture content of 44% (w.b.)
to the required moisture level of 16% (w.b.) in 4 d ays and average thermal efficiency of
drier was estimated to be 8.89%.Products dried were hygienic and their organolaptic
evaluation showed that they were of good quality and highly acceptable. Economic
evaluation was done and the money pay back period of STD was calculated as 1 yr 4
months.
