Impulse drying
Witryna11 cze 2024 · Impulse drying was developed for drying paper ( Wahren, 1982 ; Lavery, 1988 ). The wet paper sheet contacts a hot roll, and the steam pressure generated at the roll-sheet interface expels some of the water in liquid form, thereby conserving the energy that otherwise would be required for evaporation. A difficulty is that pressure … WitrynaMuch effort has been devoted to the development of press drying and impulse drying since the 1980s. In these concepts the distinction between pressing and drying is blurred since they are performed simultaneously to achieve high drying rates and special product properties.
