IMPROVED PROCESS FOR DRYING VALUABLE SUBSTANCES USEFUL FOR WASHING AND CLEANING AGENTS BY MEANS OF OVERHEATED STEAM

摘要

the products of interest or mixtures of hydrated products of interest are as wetting agents, detergents and / or cleaners and / or in the manufacture of these agents and which may also be prepared in water are dried with steam of the the hot drying gas is used.the latter is then brought to the floor of the drying after the transfer to the outside of the proportion of water evaporated in the circuit.in order to obtain a dried product of high quality, including coloured and / or deposit of carbonate, the energy necessary for the evaporation of the water is transported to the recycling stream of steam at least mainly by indirect heat exchange.
