ABSTRACT
In this study, the drying characteristics of jujubes conducted in a convective dryer were investigated under different air temperatures, air velocities, specific surface areas and densities of arrangement which conducted in a convective dryer. Furthermore, an orthogonal experiment was developed under different air temperatures, air velocities, specific surface areas and densities of arrangement. Such a reduction on drying rate was observed by the drying process. Also the total sugar of jujube was found to increase, according to the degree of influence, the order was air temperature > air velocity>specific surface area >density of arrangement; for decreasing of vitamin C, the order was air temperature>air velocity>specific surface area>density of arrangement; and for improving the organoleptic attribute which was air temperature>density of arrangement >air velocity>specific surface area. Through orthogonal optimization analysis, the optimum processing parameters were obtained under 55°C (drying temperature), 0.5 m sec-1 (air velocity), 2.5 cm-1 (specific surface area), 12.0 kg m-2 (density of arrangement). This research can provide theoretical and technical basis for drying conduction of jujubes and also an important reference value for optimizing processing technology.
