Henderson drying constants
Webdrying rate, but proper prediction of drying constants can solve this problem. The present study was undertaken to study the drying kinetics of cocoa (frosterous species) in a heated batch cocoa bean dryer, to calculate the effective diffusivity of the samples and to fit the experimental data to thin-layer drying models. Hii et al. (2009a; 2009b) Webobservations and m is the number of drying constants. The drying rate of apple slice was calculated using equation (6) [9]. Drying Rate M _ Mt dt t dt = + (6) Where, (M t+dt) is moisture content at time (t+dt) (kg water/ kgdry matter), M t is moisture content at time t (kg water/ kgdry matter) and t is drying time (min). 1.2 1 0.8 0.6 0.4 0.2 0
