Refining is a key process for a complete oil pressing line because there are still some impurities, such as phospholipids, FFA, pigment, odor, etc. in crude oil. Qi'e can provide you professional technical support and fabricate high quality oil making machines as per your specific requirements. Meanwhile, Qi'e can provide you turnkey oil refining solution.

Main Steps of Edible Oil Refining
1. Crude Oil Degumming: Gums in crude oil are removed by hydration with the help of phosphoric acid.
2. Neutralization: Free fatty acids are neutralized by using sodium hydroxide and convert them into soap. Additional impurities are also removed by adsorption on soap.
3. Bleaching: During bleaching, unwanted pigments are adsorbed physically and oil will become much clearer.
4. Deodorization: It is used to remove unacceptable odors by steam distillation, the odoriferous compound are stripped off with the help of live injected steam into heated oil under high vacuum pressure.
5. Dewaxing (necessary for cold areas)
Some kinds of oil like sunflower oil, maize germ or corn oil contains waxes inside, if these impurities are not removed, the oil will freeze easily under low temperature, thus effecting oil quality and appearance. so this process is necessary in extremely cold areas.

1. Q: Which kind of oilseeds can be processed?
A: All kinds of oil seeds. For example, rice bran, corn germ, cottonseeds, peanut, sunflower, soybean, rapeseed, etc.

2. Q: What's the capacity?
A: 1-2000 tons per day.

3. Q: Can you install the machine in local place?
A: We will send our engineers to your place for guid installation. And you shall provide the suitable labors for the installation.

5. Q: How to operate the machines?
A: Our engineers will train the worker how to operate it during installation and commissioning.
