Cooking oil deodorization process

Refined cooking oil is odorless, but the refined cooking oil obtained during processing will have different odors, some of which are very popular, such as the aroma of sesame oil and rapeseed oil. There are some smells that people don't like, such as metallic smells during processing, and smells from oils that go rancid during storage. These odors are collectively referred to as "odor".

In order to improve the flavor of cooking oil, cooking oil refineries are generally equipped with deodorization tanks to remove the "odor" in cooking oil. Deodorization is mainly based on the principle that the odor-producing substances and the volatility of cooking oil are very different, and are removed by steam distillation under high temperature and high vacuum conditions. In the process of deodorization of cooking oil, there are two issues that need the most attention. 1. Improve the quality of cooking oil. 2. Reduce environmental pollution.

Cooking oil deodorizing process

The first problem is that in the deodorizing section of our equipment, the deodorizing tank is made of SUS304 stainless steel. Under the high temperature and high vacuum environment, the processing materials will not affect the quality of oil products and ensure the safety of oil products. For the second question, using a vacuum pump can not only provide a high vacuum environment for deodorization, but also make the odor molecules in the deodorization tank trapped by the vacuum pump, reducing environmental pollution.(Recommend reading: Batch type edible oil refinery plant)
