The development history of the Condebelt paper and paperboard drying method is briefly described.
The process conditions experienced by the web during Condebelt drying are essentially similar to those prevailing in the so–called press drying experiments. In fact, condebelt drying produces. qualitywise, results quite similar to those reported by press drying researchers from many laboratories. Condebelt drying has been studied over a span of many years by means of several static units, as well as a pilot stage dynamic device. Based on these experiences, as well as several theoretical studies, designs have been developed for doing Condebelt drying as a production process.
Condebelt drying is versatile, in that the process conditions can be altered to produce optimum quality for most paper and board grades. In this capability the Condebelt process is much superior to canventional cylinder drying. The very high drying rates characteristic of Condebelt dryers are discussed, along with the Consequences as far as machine room space saving is concerned.
The good energy consumption prospects of the Condebelt process are briefly discussed
