Abstract

This research focuses on the spray drying of coconut milk powder with high fat content (50% of dry weight). The spray drying was carried out by Mobile Minor TM 2002 systems (Niro, Denmark). The influence of different technological parameters on the spray drying was examined. The central composite design method was used for operation optimization. Some optimal technological parameters of the spray drying were as follows: feed concentration: 24% weight/ weight (w/w); inlet and outlet temperatures of drying agent: 155+2°C and 75+2°C, respectively; pump rate of feed: 1.6L/h and rotary speed of atomizer: 20.000rpm. In these conditions, the product recovery yield was 82.2%.
