PROCESS AND DEVICE FOR MOULDING AND DRYING OBJECTS MADE OF FIBROUS MATERIALS

摘要

The invention concerns a process and device for molding the drying objects made of fibrous materials. The device comprises a cylinder rotating about its longitudinal axis and having a row of porous molds along the lengths of said cylinder's lateral faces partially dipping into a vat maintained at a constant level of fibrous product paste carried in appropriate liquid. A pipe connects the interior of the cylinder to the source of vacuum so as to create a partial vacuum therein. The cylinder is surrounded on its entire lateral surface between the paste vat and a removal device by an arrangement of insulating walls which defines with the cylinder and the vat an enclosure into which opens a passageway conveying hot air. The hot air is drawn off from a dryer. The present invention notably applies to the formation of egg boxes.
