Some frequently asked questions about palm kernel oil refining
Question one: What is the process of refining palm kernel oil?
Palm kernel oil refining process is an extremely complex process. The palm kernel oil refining process includes degumming process, deacidification process, decolorization process and deodorization process.
Palm kernel oil refining process
Add food grade phosphoric acid to the crude palm kernel oil to transform the non hydrated phospholipid into hydrated phospholipid, and add water to make the gum enter the aqueous phase to precipitate and remove.
Degummed palm kernel oil is added with food grade alkaline for acid-base neutralization reaction and removed by heating and natural sedimentation.
When the palm kernel oil is heated to a certain temperature, a certain amount of activated clay and activated carbon are added in the neutralized palm kernel oil, the pigment in the palm kernel oil will be physically adsorbed, so as to achieve the purpose of decolorization.
The deodorized palm kernel oil is heated to high temperature (250-260 ℃) and then enters into the deodorization tank. Under the negative pressure, a small amount of overheated steam is introduced into the palm kernel oil for stripping for a period of time, so as to achieve the purpose of deodorization.
Question two: What is the difference between physical refining and chemical refining?
Physical refining process
The main difference between physical refining and chemical refining of palm kernel oil lies in the way that how to remove FFA. Chemical refining removes the FFA in the deacidification section while physical refining removes the FFA in the deodorization section.
Chemical refining process
Comparatively speaking, physical refining of palm kernel oil is preferred in that it is a more economical process requiring less chemicals, producing less waste and giving higher oil yields.
Question three: Is refined palm kernel oil harmful to human body?
Refined palm kernel oil is crude oil produced from palm kernels, which is then refined and processed to remove impurities in the crude palm kernel oil so as to meet national sales standards. Therefore, refined palm kernel oil is not harmful to the human body.
Question four: How to choose the appropriate type of palm kernel oil refining equipment?
Henan Glory Company has three types of palm kernel oil refining equipment based on different processing volumes. Batch palm oil refining equipment is suitable for ≤20tpd. Semi-continuous palm oil refining equipment is applicable to 5-30tpd. Continuous palm oil refining equipment is suitable for 30TPD or more. You can choose according to your needs and budget.
