What's the difference between sem-continuous cooking oil refining machine and fully continuous cooking oil refining machine?

About cooking oil refining machine We have semi-continuous cooking oil refining machine and full continuous cooking oil refining machine, both types of cooking oil refining machine can remove impurities contained in crude cooking oil obtained from presses or solvent extraction plants, and improve oil functions. So, what is the difference between sem-continuous cooking oil refining machine and fully continuous cooking oil refining machine? Henan Glory Company will answer for you.  

Actually, semi-continuous cooking oil refining machine is usually used in medium scale edible oil refinery plant(10-50tpd). In semi-continuous edible oil refinery plant, the deodorization pot is replaced by the deodorization tower. So the acid refining, alkali refining, bleaching process are all still batch type, but the deodorization process is automatic. If F.F.A. content of crude cooking oil more than 5%, and you don’t want to get large quantities of soapstock, semi-continuous cooking oil refining machine is the best choice.

General speaking, for 30tpd and above, the full-continuous cooking oil refining machine is much better for large scale edible oil refinery plant. The fully continuous refining and deacidification section is equipped with a disc centrifuge to replace the natural sedimentation of soapstock, and each section is continuous production without interruption, however the cost of full-continuous cooking oil refining machine is high, the quality is much more steady and average. The whole cooking oil refining process is totally automatic. There are more equipment in full-continuous cooking oil refining machine, and the refining process is more complicated.

Full-continuous cooking oil refining machine  

Crude cooking oil includes moisture, solids, gums, free-fatty acids (FFA), waxes, and compounds of sodium, potassium, magnesium, calcium, and other metals. All these impurities are removed in a series of steps: degumming (to remove gums), deacidification (to remove FFA), decolorization (to remove color), deodorization (to remove odor and taste), and dewaxing or winterization (to remove waxes)，Both semi-continuous cooking oil refining machine and full continuous cooking oil refining machine can complete the above-mentioned refining process. Which type of cooking oil refining machine to choose specifically depends on the quality and production capacity of your crude cooking oil to design a suitable cooking oil refining machine for you.
