填料式脱臭器的应用

Application of Packing Deodorizer

介绍填料脱臭器的结构特点，工艺要求；比较传统的塔盘式脱臭器，其结构填料比表面积大，塔体流体滞流时间可调，蒸汽消耗仅为塔盘式脱臭器的３０％。脱臭成品油中ＦＦＡ最终含量≤０．０３％，油脂热聚合及生成反式酸的机率较少，维生素Ｅ损失少。

This paper is introduced the structure feature and process requirement of the thin-film deodorizer, Comparison with tray-deodorizers the surface-to-volume ratio is larger, and retention time can bcadjustcd. During the stripping of frcc fatty acids, sparging stcam is needed only for mass transfer, not for agitation,so that the steam consurnption is 30% that of a tray-deoderizer FFA content in the deodorized oil0.03%. Formation of the thermal polymers and trans-fatty acids is limited. Vitamin Elass less,Leading to a very qentle oil.
