Abstract
A process is described for drying melamine wet cakes, comprising the steps of: a) providing a turbo-dryer (T) comprising a cylindrical tubular body () having a heating jacket (), inlets and outlets () and a bladed rotor () rotatably supported therein; b) feeding a continuous flow of a melamine wet cake into the turbo-dryer (T), the internal wall () of which is maintained at a temperature of at least 220° C.; c) feeding a continuous flow of a gas selected from air or nitrogen into the turbo-dryer (T); d) subjecting the flow of melamine wet cake to the mechanical action of the bladed rotor () rotating at a speed of at least 200 rpm, with consequent centrifugation of the wet cake against the heated wall (), thus causing the instantaneous evaporation of the water contained into the cake, and transport of the latter towards the outlet (); e) continuously discharging, after an average residence time of less than 1 minute, a flow of melamine crystals having a humidity content of less than 0.1%.
