对油脂碱炼工艺的改进

Improvement of oils neutralization process

碱炼工序在食用油生产过程中具有重要的作用。在生产实践的基础上,总结出了一套间歇改良式的碱炼、水洗,连续式油水分离的半连续碱炼工艺。该工艺投资少、炼耗低、碱炼油品质好、废水少、操作维修费用低、技术要求不高,是一条简单实用的碱炼工艺,特别适合中小型油脂精炼厂应用。对于后续配套的物理精炼,借助于本工艺对油品进行强化脱磷,其优越性也很突出。

Neutralization process plays an important role in the production of edible oil with high quality. The traditional neutralization has some limitations whether in batch or in continuous process. Therefore, basing on the production practice, a improved semi -flow sheet process was designed , i.e. batch neutralization, washing, and centrifugal separation of oil and water. As a matter of fact, it＇ s a simple and practical neutralization process with low cost and high quality product, especially for the edible oil refinery factories of middle and small scales. At the same time, it also has excellent advantages in favor of the succeeding oil physical refining.
