摘要：

Drying ability of date (Phoenix dactylifera L.) pulp cubes from three Algerian common varieties (Mech-Degla, Degla-Beida, and Frezza) were investigated. Drying process was carried out under partial vacuum (200mbar) at 60, 80, and 100 degrees C. Compared to the Newton model, the Henderson and Pabis model better described drying kinetic of Mech-Degla and Frezza pulps at 60 and 80 degrees C with a mean relative error (MRE) not higher than 6.07%. The same model fits experimental data at 60 degrees C for Degla-Beida (R-2=0.988; MRE=6.07) as well as at 100 degrees C for only Mech-Degla (R-2 > 0.98, MRE=8.61%).
