PROCESS FOR OBTAINING VANILLA POWDER FROM ETHANOLIC VANILLA EXTRACT.

摘要

The present invention relates to a process for obtaining a vanilla powder from an ethanoic extract of natural vanilla with a high concentration of aromatic compounds using a closed cycle spray dryer with nitrogen as a drying gas with a support material malt dextrin DE-10 80% concentration, dryer inlet temperatures of up to 180°C and outlet temperatures of up to 90°C. The product obtained has endless applications in the food industry, liquor, beverage, pharmaceutical, cosmetic, tobacco, among others. The process is integrated by two continuously steps: (a) prepare the dryer feed mixture, (b) dry the mixture in a spray dryer coupled to a heat pump and a dehumidifier (closed cycle) with Nitrogen as drying gas. The extract is fed without prior evaporation of ethanol avoiding the risk of explosion due to the absence of oxygen in the system.
