ABSTRACT:
Apparatus for removing volatile components from a liquid includes three distinct sections of a confined passageway for the liquid. The first section is for heating the liquid to a predetermined temperature at a preselected pressure such that vaporization of the volatile components is prevented. The second section of the confined passageway is a restrictive orifice forming flow path. The third section is a volatile component evaporation section. The volatile component evaporation section and the restrictive orifice forming flow path are dimensioned relative to one another and in respect of the preselected pressure and temperature of the liquid product such that the volatile components of the liquid substantially instantaneously vaporize in a flashing action as the liquid passes from the restrictive orifice forming flow path to the volatile component evaporization section. The volatile component evaporation section is also dimensioned such that the vaporized volatile components flow as a high velocity vapor carrying the liquid in atomized form and subject the atomized liquid to turbulent stripping.
