“…Between 0.000008 and 0.072017, the most suitable models for longan were Midilli and Wang and Singh, respectively. Obtaining the drying kinetics data is essential for optimizing the drying process, The k coefficient represents the drying rate [16]. From tables 2, k increases as the drying temperature increases.…”

Abstract. In this study, the single-stage drying in tray dryer at air temperatures of 40, 50, 60, 70 and 80˚C is modelled and investigated. The longan fruits, E-dor variety, are peeled and seeded before testing. The drying rate is significantly influenced by the drying techniques and temperatures. Drying rats are initialized adjustment constant rate periods at 60 70 and 80˚C. The rate of moisture removal is rapidly changed drastically during the falling rate period. The Midilli model with high R 2 and low χ 2 and RMSE is the most suitable model for predictability of longan drying. Variation rates of quality of the water activity, the shrinkage, and the browning index are also reported.

“…Perea-Floresa et al [15] studied the drying kinetics of castor oil seeds during fluidized bed drying at a constant air velocity and at high air temperatures using diffusion approach model. The moisture loss from the seeds was described by the Fick's diffusion equation, and based on the obtained results the effective moisture diffusivity was estimated.…”

Drying of food and grain material for removal of moisture is an important aspect in preserving them or for extraction of oil. It is a complex process involving both heat and mass transfer. The present work is aimed at developing a simple mathematical model with governing differential equations and proper boundary conditions for spherical shaped food material to determine the rate of moisture removal. The differential equations are solved using numerical technique with the help of a computer Program and the results are presented in graphical form. The variation of temperature within the seed with respect to time for various drying medium temperatures considering the partial pressure of water vapor in the drying medium are presented. The rate of moisture removal with respect to time for different convective environment conditions and varying resistance within the seed is also presented. A generalized correlation to determine the moisture rate removal as a function of Fourier number, Biot number and Mass transfer Parameter is developed for estimation of time required for heating under different hot air conditions for various spherical shaped fruits or grains. This non-dimensional correlation is helpful in quick estimation of time for drying of any seed and hence would be useful in the Agro Industry.
