Thus the system can meet the demand of different drying processes of different materials.
If the heat pump unit has not the auxiliary evaporator, the method lifts the drying temperature slowly and the dehumidification of materials is very limited at the initial drying stage, so drying time of the material is increased.
In order to make clear the effect on the material’s drying rate at the same drying conditions, the sliced potatoes were chosen as the drying materials and the drying temperature was 55℃.
The drying temperature histories of the two lifting temperature methods were shown in “Fig. 4(a)”, and the materials’ weight histories were shown in “Fig. 4(b)”.
