Abstract

Drying is an operation which involves simultaneous heat and mass transfer, Hence there is a need for the evaluation of various transport parameters which are useful in the design of commercial dryers. Therefore, the di@sivity coeficient at different temperatures (323-353 K) was evaluated for toria (Brassica campistris var. toria) seeds. Initially, the equilibrium moisture content-relative humidity (EMC-RH) data were measured, and the results are reported in the form of Henderson’s equation. The characteristic drying rate curve was obtained by measuring the moisture present afrer different times. The diffusivity coefficient was calculated ffom the above data in the falling rate zone, and the effect of temperature on the difisivity coeficient was described by an Arrheniustype relationship:
