Abstract

In this research, a new product of purple passion fruit (Mac Mac), "Passion fruit powder" was studied. The experiments were carried out on the semi-industrial spray dryer MOBILE MINOR, from NIRO company, Denmark. In order to maximize the product recovery yield of spray drying of passion fruit powder, dry mass of passion fruit juice before drying, initial air temperature, air pressure for atomization and pump rate were studied. The results showed that, the efficiency was 75-78% when the studied parametters were 8%, 165°C, 4.25 bar and 10 rpm, respectively.
