  • partial evaporation solely by supplying heat is disadvantageous compared to partial evaporation by lowering the pressure, in that the evaporation essentially only occurs where the heat is supplied, while a decrease in pressure affects the entire liquid volume and leads to a more uniform evaporation, which also occurs in the The area of the fiber material takes place where mixing of the liquid is most effective.
