The four-stage vertical oven designed and built by GiardinaGroup and available through Schuberts, optimally performs the four phases that characterize a perfect drying process: flash-off, first heating, second heating, and finally cooling.
The drying curve is guaranteed by the four stages in which the oven is structured, one for each phase, and each stage is separated from the other by dividing panels. In other two- or three-stage ovens, instead, some of the four phases are performed in the same spaces, therefore a homogeneous separation between them is not guaranteed and the zones are joined, mixing air and conditions inside – a less than ideal situation!
The version of four-stage vertical oven presented in the above video link, adopts a belt tray system, perfect for small pieces (there are no dangers related to their handling or dropping through) and for large and heavy elements which, being able to rest on a large and regular surface, do not risk any damage or marking to the contact surface already painted, with the tray system offered by others.
On request, it is possible to have the GiardinaGroup four-stage oven in an ideal set-up for those who have to process both thin pieces (flat doors) and high-thickness ones (curved doors): by reducing the number of trays the problem is solved, keeping the duration in each phase and for each product, whatever its thickness, constant and homogeneous.
