No matter what kind of crude vegetable oil to be refined, there are two methods to choose: chemical refining technology and physical refining technology. For coconut oil, which refining technology is more suitable? Let's discuss it today.
The characteristic of coconut oil chemical refining technology:
As the above picture shows that coconut oil chemical refining process contains four steps: degumming, neutralization, bleaching, deodorization.
Actually, there is no big difference between coconut oil and other crude vegetable oil chemical refining technology, such as soybean oil, canola oil. The only difference is that it doesn't need water degumming technology, because it has very low content of colloidal impurities, which is like crude palm oil. Another point worth to pay attention to is that coconut oil is very easily saponified, so if alkali refining process is improperly controlled, it will increase neutral oil loss. If you choose chemical refining technology to refine coconut oil, engineers' commissioning is very important, which can make sure that your coconut oil refinery plant have best effect, and the production consumption is low.
The characteristic of coconut oil physical refining technology:
The coconut oil physical refining process is a little different from chemical refining process. The deacidification process uses distillation method instead of neutralization method, and can obtain pure free fatty acid.
The biggest advantage of coconut oil physical refining technology is to avoid the environmental pollution of waste water produced in chemical refining process. Coconut oil physical refining technology uses distillation method to remove the free fatty acid and odors. You can get pure free fatty acid and sell them at good price. In addition, the crude coconut oil usually has high acid value, using physical refining technology can obtain better quality RBD coconut oil.
Though the coconut oil physical refining technology has better effect,
its price is expensive, too. If your budget is not enough, small scale
coconut oil chemical refining machine is also a good choice. Latter, you
can also expand the production scale when having economic power.
