Title:
PRODUCTION OF SORBITOL POWDER HAVING HIGH FLUIDITY
Document Type and Number:
Japanese Patent JP2577698
Kind Code:
B2
Abstract:

PURPOSE: To provide a method for producing sorbitol powder having high fluidity, capable of continuously producing and having high economical efficiency.
CONSTITUTION: An aqueous solution of sorbitol adjusted to 89.0-99.9wt.% purity, 69-80wt.% concentration and 10-40°C temperature is continuously fed to a sorbitol massecuite tank previously kept in the range of 5-35wt.% crystal amount at a rate corresponding to 0.5-80wt.% of the massecuite weight per hr. At the same time, the massecuite continuously pulled out from the outlet of the massecuite tank at a similar rate as feed rate of the aqueous solution of sorbitol is introduced into spray-drying apparatus controlled to 30-90° air temperature and spray-dried. Thereby, sorbitol powder having high fluidity and free from scattering of fine powder is obtained.
