Corrugated board is over 150 years old. The first information about “paper or other material corrugating” may be found in a British patent by Edwarda G. Healyho and Edwarda E. Allena (1856). The manufacturing of corrugated board was patented in 1871 in US by Albert Jones. Rumor has it that the first corrugating machine was made from old cannon barrels from the Civil War. The inspiration was gained from pleated women skirts. His goal was to find an elegant and safe way to package glass bottles. Oliver Long improved his patent three years later by adding a solid board to the corrugated one - getting a two-ply board. In 1883 in London the first European corrugated board factory began operating. The 20th century brought the development of new machinery and techniques for making corrugated board.

Corrugated cardboard is produced through curing multiple layers of corrugated paper on a corrugating machine. The multiple layers are adhesive together with layers of straight paper. The drying step is very important to glue those multiple layers as the drying process causes the starch to become a gel - this glues firmly together all layers.

Industrial Conveyor furnace Microwave could efficiently dehydrate the gluing corrugated boards. Microwave can penetrate the core of corrugated boards and remove the inside moisture of corrugated boards. Unlike hot air dryer and conventional dryer, microwave can uniformly drive unexpected moisture quickly in order to shorten drying time and save energy consumption.

MAX Conveyor Furnace Microwave Heating System is a new trend corrugated board drying solution that is widely used in the corrugated process.
