Abstract
Process for preparing soluble coffee powder, obtained by dehydrating an aqueous extract of roasted and ground coffee, characterized in that it comprises the steps of: a. Evaporate the volatile flavor components of the aqueous extract of coffee in an evaporation zone where an absolute pressure of between 406.4 and 508 mm of mercury is maintained and where 5 to 15% of the extract water is vaporized watery coffee, said water vapor containing the flavor components separated from the coffee; b. Partially condensing the water vapor mixture containing separate volatile flavoring components, in a condensation zone where an absolute pressure of 406.4 mm of mercury is maintained and the atmospheric pressure, the condensate being found, as it leaves the condensation zone, at a temperature comprised between 0.55 and 21º c, to recover the aqueous solution of condensed flavoring and flavoring components; c. Concentrating the aqueous extract of coffee separated from step (a) to form a concentrated coffee extract having a solids content of 37 to 55% w/w; d. Mixing the aqueous solution of flavor components of step (b) with the concentrated coffee extract of step (c); and. Feeding the mixture of step (c) to a spray dryer at a temperature suitable for spray drying, of the order of -2.8 to 93º c; f. Spraying the mixture of step (e) with a droplet size comprised between 100 and 300 microns, using a pressure in the spray-drying nozzles comprised between 21 to 175 kg/cm2 relative, an inlet air temperature of 121 to 288ºC and an outlet air temperature of 82 to 93º c, said mixture having a temperature comprised between -2.8% and 93% at the entrance to the dryer.
