An Atmospheric Steam Superheater for Steam Distillation of Food Antioxidants

摘要

A steam superheater was designed and built to operate at atmospheric pressure and to provide superheated steam for as many as twelve edible fat and/or oil samples undergoing steam distillation for BHA and BHT antioxidants. The steam flow rate is sufficient to yield a distillate flow rate of four ml/min for each sample. Superheated steam is injected at a high enough temperature to maintain the sample mixture at 160C. with little or no change in volume. (Author)
