ABSTRACT
A process for the condensation of a volatile-rich
vapor stream produced by a stripping operation from
a vegetable or fruit product or the extract thereof,
which comprises the steps of:
(i) condensing a major proportion of the water
present in the vapor stream using a surface condenser
with water as a coolant;
(ii) subjecting the condensate of step (i) to
further cooling in a heat-exchanger using water at a
lower temperature than that of step as the
coolant; and
(iii) contacting the cooled condensate from
step (ii) with the vapor stream issuing from the
condenser of step (i) in a countercurrent absorption
column.
The process is particularly applicable to the
condensation of a volatile-rich water vapor stream
containing coffee volatiles.
