The panels still have a high temperature after pressing. Before further processing they must therefore be cooled until a temperature is reached at which the panels can be stacked and stored - the storage temperature. This process is also called conditioning.
Conditioning is carried out in a star cooler: a gradually rotating star of narrow compartments, each of which is big enough to hold one panel. Each compartment receives a panel and then rotates further step by step. After one half of a full circle, enough time has passed for the panel to reach its storage temperature and leave the star cooler.
