Abstract
Method of producing granulated maltitol, including the stages: preparing maltitol syrup having less than 50 wt.% dry matter and greater than 70 wt.% maltitol, introducing to a fluidized air bed granulator, a pulverulent bed of crystallized maltitol with a concentration at least equal to 99 wt.% and a mean diameter between 30 and 100 μm, controlling the air inlet temperature between 100 and 120° C. and air velocity between 1 and 2 m/s, fine spraying the maltitol syrup into the granulator, at between 35 and 45° C., onto the moving pulverulent bed; the bed being between 30 and 60° C.; the mass of the bed representing constantly at least 2.5 times the mass of the sprayed syrup, drying, after fine spraying, by raising the air temperature below the melting point of maltitol to obtain a bed temperature between 70 and 80° C., cooling the granulated maltitol to at most 25° C. and collecting.
