7.1.1 Power failure

The control system continues with the process after a power failure. The

preselected conditions remain saved even during a process run.

In the event of a power failure in the drying phase, the batch may become

unusable. Whether the batch can be saved or not depends on the drying

phase in which the product was when the power failure occurred.

• In the final drying phase, the product has reached a residual moisture

content of approx. 5%. Below this value, the product is generally not

damaged even if the power failure lasts for a longer period of time.

• If the product is in the main drying phase, we recommend aerating the

unit, removing the product, and storing it in a deep-freeze. The

defrosted condensate must be drained off prior to the next start.
