ABSTRACT OF THE DISCLOSURE A method is disclosed for applying thermal and/or chemical treatment to a dispersible fluid phase, such as in particular a liquid, semi-liquid or powder, by means of a dispersing gas phase, characterized in that the following steps take place successively and without discontinuity, by the action of the gas phase: (a) the dispersible phase is converted to a dispersion of component volumes, such as fine solid or liquid particles, which are substantially evenly distributed within said gas phase so as to give a systematically homogeneous mixture of the two phases, namely the dispersible and dispersing phases; (b) the dispersion undergoes flash treatment in a zone with plug type flow; (c) the dispersion emanating from zone of step (b) undergoes treatment which is both substantially isothermal and chemically homogeneous, in a zone with a flow which is homogeneous in the sense of the distribution of dwell times. The method of the invention overcomes some tricky problems which have plagued prior efforts in this field. The products of the method of the invention are useful in the food and detergent manufacturing industries.
