Development of low-temperature drying technology and potential alternatives

Reinhold Hempelmann

The discussions on pulp drying systems have lately become more and more intense. In the first place, these are concerned with systems which utilize available waste heat, e.g. low-temperature driers, or with systems which use superheated steam for drying purposes. This is the basis on which BMA devises its trend-setting concepts. The current state of development in low-temperature pulp drying is chiefly characterized by heat exchangers arranged closely above the belt conveyors and the short air routes provided by built-in fans. As regards steam drying, an alternative to the fluidized-bed drying technology is developed which incorporates a drum dryer (Niro A/S licence). Various drying systems and combinations thereof are evaluated.
