Calcium magnesium citrate drying at bench scale

Abstract:

Calcium and magnesium citrate is a raw material obtained from dolomite. As part of the optimization of technological process, we studied it at bench scale, the dry stage to pbkp_redict its behavior at higher scales. Results of this study showed that from 7:30 hours, sample drying reaches a humidity content lower 5 %. Besides, we noted that during the first 6 hours, quantity of evaporation water represents more than 85 % of total quantity present in sample. We conclude that drying process is appropriate to guarantees that calcium and magnesium citrate has humidity content lower than that required for raw products of pharmaceutical quality. © 2009 1999, Editorial Ciencias Médicas.
