How many types are there of crude sunflower oil refining mills?

According to the input capacity, the crude sunflower oil refining mills can be divided into three types: Batch type, semi-continuous type and full-continuous type.

The detailed introduction:

Based on the refining method, the crude sunflower oil refining mills can be divided into two types: chemical sunflower oil refining mill and physical sunflower oil refining mill.

Chemical sunflower oil refining mill:

Chemical sunflower oil refining mill mainly refers to using chemical method in deacidification process. Through adding alkali to neutralize the FFA in the crude sunflower oil, the acid value of the sunflower oil will become lower, and which can be store for longer time. Generally, if your crude sunflower oil has high acid value, the engineer will advise you to choose the chemical sunflower oil refining mill.

So physical sunflower oil refining mill mainly refers to using physical method in deacidification process. Here, it is using distillation method to remove the FFA from crude sunflower oil. It is worthy to say that you can get pure FFA using physical deacidification method, and the pure FFA can be sold at a very high price.

What's more, if you want to build a physical sunflower oil refining mill, there are two conditions you need pay attention to. One is that your crude sunflower oil should be with low acid value, and other one is that you should have enough budget because physical sunflower oil refining mill is often more expensive than chemical one.
