Drying processes, in particular for thermally labile products

摘要

Drying processes, in particular for thermally labile products, characterized in that the supply air to form a dryer (tr) an absolute air humidity of a maximum of 1 g / kg and is formed in a either as a regenerator or as a recuperator, which is operated as a countercurrent heat exchanger (pbw), indirectly with the exhaust air from the dryer (tr) and thereby brought to the heat exchange is cooled to a temperature below the cooling limit temperature of the ambient air is.
