Patent ID: 8518185

Claim:
A method of production of granulated maltitol, comprising the following stages: a) preparing a maltitol syrup having a dry matter less than 50 wt. %, and with a maltitol concentration greater than 70 wt. % of the carbohydrates of said syrup, b) introducing, in a fluidized air bed granulator, a pulverulent bed of crystallized maltitol with a concentration at least equal to 99 wt. % and having a mean diameter between 30 and 100 μm, c) controlling the air inlet temperature of the granulator to a value between 100 and 120° C., and the velocity of the fluidization air to a value between 1 and 2 m/s, d) fine spraying of the maltitol syrup from stage a) in said granulator, at a temperature between 35 and 45° C., on the pulverulent moving bed of particles of crystallized maltitol of stage b); said bed having a temperature between 30 and 60° C.; the mass of the bed representing constantly at least 2.5 times the mass of the sprayed syrup, e) drying by raising the temperature of the air of the granulator, at the end of fine spraying of said syrup, to a temperature less than the melting point of maltitol until the temperature of the bed is between 70 and 80° C., f) cooling of the granulated maltitol thus obtained to a temperature of at most 25° C. and collecting the granulated maltitol thus obtained.
