coefficient during greenhouse fish drying for prawn (Macrobrachium
lamarrei) under forced convection mode has been performed. The experiment
has been performed during July 2006 for the composite climate of New Delhi.
The hourly data for the rate of moisture evaporation, wind velocity, fish
temperature and relative humidity inside greenhouse have been recorded
for complete drying of fish under both natural and forced convection mode.
These data were used for determination of the coefficients of convective
heat transfer. Convective heat transfer coefficients are higher for forced
convection than natural convection drying. Also the drying time required
for forced convection is lesser than natural convection drying. It is
mainly dependent on the rate of moisture transfer under the drying process.
The curve fitting was carried out for different available model out of
various observations. A quadratic curve exhibited best relation between
convective heat transfer coefficient and drying time. This model gives
the maximum coefficient of determination.]]>Anwar, S.I. and G.N. Tiwari, 200142627637Ayyappan, S. and A.D. Diwan, 2003534751Bala, B.K. and M.R.A. Mondol, 200119427436Doymaz, I. and M.
