Generally speaking, after we press palm fruit, we will get the crude palm oil. Due to there are still some impurities such as phospholipids, FFA, pigment, odor, etc. in the crude oil, and these impurities will directly change the oil's color, smell, taste, transparency, stability degree and nutrition, which not only affect the price of edible oil, but also make the oil easy to deteriorate when storing. So we need to use palm oil refining machine to refine the crude palm oil to get high quality cooking oil.

Small scale palm oil refining machine

Depending on the different of customer's requirements and production scale, there are three different types of palm oil refining machine can be chose to produce cooking oil, they are: batch type palm oil refining machine, semi-continuous palm oil refining machine and fully continuous palm oil refining machine. Today we mainly introduce 1-10tpd batch type palm oil refining machine. (Related post: What is the price of palm oil refining machine?)

As with continuous palm oil refining machine, 1-10tpd batch type palm oil refining machine also includes four mainly processes: degumming, deacidification, decolorization, deodorization. Here, Henan Glory Oils & Fats Engineering Co., Ltd will take you learn about each refining process of batch type palm oil refining machine.

Degumming section: There are some phospholipid, gum, and protein, they can be dissolved into oil when there is no water, but once there is water in oil, these impurity can be dissolved into water. So, in degumming section, we usually use the hot water to wash crude oil for two-three times to make gold phospholipid condenses and reduces colloid, To reach the better dugumming effect, we usually need wait several hours,then open the below valve release the gums.

Deacidification section: During this section, The most widely used method is adding some chemical materials (alkali liquor) to remove the acid materials. And then open the below valve release the soapstock.

If the content of FFA in crude oil is high, we will lost much oil and get much soapstock. But if the content of FFA in crude palm oil is low, we will get more oil and less soapstock.

Decolorization section: Decolorization is carried out by the obsorption function of white clay, this step usually need 25mins, temperature requirements around 105-110 Celsius.

Deodorization section: This step have high temperature requirement , around 260 Celsius, based on very high temperature, steam can remove oxidation number, aldehydes, and ketones in crude oil. In addition, some of acid and bad smell also can be taken off in this step..

After the above four step, we will get the RBD palm oil, if you want to further process RBD palm oil to get palm olein and stearine, we can also supply the palm oil fractionation plant.
