Recovering gylcerin and other heat sensitive, solids-containing valuable food additves can not be effectively accomplished using conventional evaporation techniques.

use an Artisan Rototherm^® mechanically-agitated thin film processor to continuously evaporate and distill glycerin and other heat sensitive solids-containing products, without color formation, while achieving greater than 96% yield. Owing to its extremely short residence time, narrow residence time distribution, rapid surface renewal, and high heat transfer rates, product degradation is minimized, while purity and yield are maximized.

Material: Vegetable oil containing 20% glycerin and 2% sodium salts

Through continuous vacuum evaporation/distillation, highly purified glycerin is recovered overhead while a concentrated oil/salt residue is discharged as waste.
