Gypsum board drying technology has undergone significant advancements, presenting a spectrum of cutting-edge techniques, primarily segmented into hot air drying and indirect heating drying with the aid of thermal oil. Among these, the hot air drying method emerges as the frontrunner for large-scale production lines. It excels in the rapid, efficient removal of moisture from gypsum boards through the dynamic and precise application of hot air, guaranteeing swift dehydration. As each gypsum board moves through an extensive system of conveyor rollers within the drying chamber, it experiences a profound reduction in moisture content, reaching an exceptionally low level. Once this meticulous journey is complete, the freshly dried gypsum board exits seamlessly from the outlet, fully prepared for immediate use.
In the arena of gypsum board drying solutions, cutting-edge innovation has ushered in a variety of equipment types, with hot air drying and indirect heating drying using thermal oil being the primary categories. The hot air drying technique, in particular, is predominantly employed in expansive production environments due to its unmatched efficiency in rapid dehydration. This method effectively utilizes strategically deployed hot air to accelerate moisture removal. As each gypsum board travels across a series of extended conveyor rollers within the drying environment, it undergoes a significant decrease in moisture content, achieving impressively low levels. Ultimately, the completed gypsum board is smoothly conveyed to the outlet end, where it is promptly collected, poised for further use.
