A method for the production of spray dried sorbitol and drying of the sorbitol particles on a subsequently connected fluidized bed, and spray-dried sorbitol

摘要

A method for the production of spray dried sorbitol, by means of spraying a 65 to 75% strength sorbitol solution in a spray tower by means of a rotary atomizer in the direct current with a finely divided sorbitol - circle barrel crystals with the supply of hot air and a subsequent fluidized bed in order to further drying of the sorbitol particles, characterized in that the sorbitol solution before supply to the atomizer to a viscosity of 8 to 50 mpa · s is adjusted, the atomizer with a rotational speed of 5000 to 15000 u / min is operated, circle running in an amount of from 3 to 4 kg / kg of end product is supplied to and at the spray tower outlet the temperature of the exhaust air via a control system continuously measured and the temperature of the supplied hot air in a range from 105 to 150°C. is changed, in such a way that the outgoing air temperature at a constant value of 55 to 57°C. is maintained, and warm air in an amount of from 14 to 22 m³ in the normal condition / kg of end product is fed, and then emerges at the spray tower the accumulation of sorbitol is supplied directly to the fluidized bed downstream of, by means of..
