| Manual Control | Automatic Control |
|---|---|
| One-off sampling, small volumes of samples (100-200 g) | Continuous measurement with large volumes (2 m3) |
| Measuring takes place at the end of the process, with delay | Continuous measuring |
| Intervention is subjective and late | Intervention takes place instantly when objectively required |
| Possibility of subjective errors | Subjective errors excluded, instrumental control |
| The possibility of over-drying to be on the safe side | Regulated to achieve the set value |
| Journal recorded by the operator | Automatic data collection, feedback enabled |
It is obvious that automatic regulation is the only solution for managing an energy-saving, reliable and subsequently controllable drying method.
