Heat Conservation Chamber
The NSD is specially design with 3 layers of conveyors, each layer
with different drying features:
l When the fabric enters the 1st layer conveyor, the surface temperature starts from 35°C and increase gradually as it moves along. Since the humidity is low at the 1st layer since the temperature has not reach the evaporation point, no exhausting action will be done on the 1st layer, to preserve heat and segregate from the 2nd layer.
l When the fabric enters the 2nd layer, the surface temperature is reached to evaporation point. The newly design exhausting system will only exhaust this 2nd layer humidity without effecting the other layers. This will greatly increase the heat efficiency of NSD and avoid unnecessary heat lost by the exhausting action.
l When the fabric reaches the 3rd layer, the drying process is almost done. The water content in the fabric is low and the air temperature at the 3rd layer is higher than the above layers. All the hot air in the 3rd layer will be recycled back immediately to the heat exchanger for great heat usage.
