Specialities of CRS Drier :
-
It is reliable, energy saving and automatic for drying plastic granules. The use of Dry Air makes drying faster and more efficient than Hot Air Driers.
-
Specially suitable for all Hygroscopic plastic materials, such as ABS, Nylon, Pet, Polycarbonate, PVC etc.
-
Maintenance is limited to filter cleaning only as the system is very effectively controlled, replacement of drying medium is virtually unnecessary.
-
Microprocessor Controlled.
-
The dew point during the drying process is - 35°C (:t 5OC) constant.
-
Very economical, minimizes rejection in production.
| OPERATING PRINCIPLES OF C R S DEHUMIDIFYING DRIER |
|
Functional Diagram of Machine Mounted Drier |
Drying :
During the drying cycle, the Dehumidified air operates in a close circuit. In this way, the Drier is completely independent of variation in the atmospheric moisture and ensures that the drying performance always remains constant.
Regeneration :
In the normal direction of rotation, the Blower circulates the dry air and in the opposite direction it regenerates the desiccant. In the way, the water in the desiccant of the Drier, which has been carried over from the granules is expelled from the Drier. |
|
The advantage of Dehumidified dry air over hot air
is illustrated by the following curves : |
|
-
Curve (1) : Summer and monsoon weather: Maximum humid conditions, 38° .C, and above 90% relative humidity. After four hours drying, it is only just possible to reduce the water content of the granule to 0.15% H2O.
|
Curves |
-
Curve (2) : Autumn and Spring: 25° C, 70-80% relative humidity, after 4 hours drying a relative humidity of 0.1% H20 can be reached.
-
Curve (3) : Winter weather: 15° C, 70% relative humidity after 21/2 hours 0.1 % relative humidity in the granule is reached, and after 4 hours, 0.07% H2O can be reached.
-
Curve (1), (2) & (3) therefore, under different humid condition indicate the dependence of hot air driers on ambient conditions.
-
Curve (4): With dehumidified hot air: Shows the reduction in moisture experienced when using CRS Drier as the dew point of this air remains constant at below (-) 30° C with a water content of only 0.3 g. per N m3 air. The drying cycle is totally independent of weather conditions.
