　　This paper introduces the meaning and essence of the principle of dewaxing oil equipment

　　因为油脂汇总富含微量蜡质，即可使浊点添加，是油品的透明度和消化吸收率下降，并使油脂气味和适口性变差，从而下降油脂运用质量、营养价值及工业运用价值，因而，精炼设备的脱蜡对于油脂精炼含义严重。

　　Because rich in trace waxy oil summary, you can make the cloud point add is oil transparency and digestion and absorption rate decreased, and the greasy smell and taste variation, so as to reduce oil use quality, nutritional value and industrial application value, therefore, pristine devices dewaxing for oil essence meaning severe.

　　精炼设备脱蜡的肌理 ：

　　The essence of the texture of dewaxing device:

　　因为蜡质是一种带有弱亲水基的亲脂性化合物。温度高于40度时，蜡的极性弱小，溶解于油脂;

　　Because the wax is a lipophilic compound with weak water-based dear. When the temperature is above 40 degrees, the polarity of wax is small and weak;

　　跟着温度的小将，蜡分子在油中游动性下降，蜡分子中的酯键极性强，特别是低于30度时，蜡成结晶分出，并构成较为安稳的胶体体系，低温继续，蜡晶体构成较大晶粒，密度添加而构成悬浊液;

　　Along with the temperature of the teenager, wax molecules in oil motility decreased, strong polar molecular wax ester bond, especially below 30 degrees, wax crystallization separation, and constitute a relatively stable colloidal system, continues to low temperature, the wax crystals constitute larger grain density add a suspension.

　　由此可见，油和蜡之间的界面张力跟着温度的改变而变编，两者界面张力的巨细和粘度成反比联系，这即是为什么精炼设备脱蜡工艺需要在较低温度下进行的理论依据。

　　Thus, the interfacial tension between oil and wax followed the change of temperature and variable encoding, interfacial tension of both size and inversely proportional to the viscosity relationship, which is why essence oil dewaxing process must be under the lower temperature of the theoretical basis.
