Abstract

A procedure for freezing concentration of coffee extract, freezing an extract with a solids content of 20 to 30% by weight, to form ice crystals constituting a cake and centrifuging the cake to separate concentrated extract, characterized by carrying out consolation under conditions that provide relatively large uniform crystals of size 0.5 to 2.0 mm, said conditions including a "U" factor (Kcal.hr-1.m-2.ºC-1) of 122 at 488 and a delta T of approximately 13.9ºC to 33.4ºC, so that the cake is porous, centrifuge in a loading phase at low speed and a terminal phase at high speed, and wash the crystals in the last part of the loading phase.
