What is the difference between vegetable oil refining equipment and animal oil refining equipment? This question was seen by the author in the bidding backstage. Through this question, the company’s keyword was triggered. Upon seeing this question, the author felt that it was time to write an article about vegetable oil refining. The article on the difference between equipment and animal oil refining equipment.

1. What are the processes in vegetable oil refining equipment?

(1) Degumming: removing phospholipids, mucus, resins, proteins, sugars, trace metals, etc. in the crude oil, generally using hydration and acid refining methods.

(2) Deacidification: Use food grade lye neutralization method to remove free fatty acids, acid pigments, sulfides, insoluble impurities and trace metals in the oil.

(3) Dehydration: Use heating and vacuum drying to remove the water in the refined oil.

(4) Decolorization: Use adsorbents such as clay, aluminum silicate, and activated carbon to remove various pigments, colloids, oxides, etc. in the oil.

(5) Deodorization: The principle of vacuum stripping is used to remove low-molecular odorous substances, free fatty acids, monoglycerides, glycolipids, sulfides, and thermal decomposition products of pigments in the oil.

(6) Dewaxing or degreasing: mainly use freezing, crystallization or winterization crystallization, and fractionation to remove wax or solid fat in the oil.

2.What are the processes of animal oil refining equipment?

(1) Process flow of chemical animal oil refining equipment:

Starting from crude oil, hydration dephosphorization and degumming, then acid-base neutralization, and vacuum drying, then remove the color in animal fat, deodorize by distillation, then heat exchange, and finally obtain refined product oil.

(2) Process flow of physical animal oil refining equipment:

Starting from crude oil, hydration, dephosphorization and degumming, and then vacuum drying, then remove the color in animal fat, heat exchange, physical deodorization and deacidification belong to continuous distillation, deacidification and deodorization. One device completes two functions, and then After cooling, the finished animal oil is finally obtained.

After we show both the vegetable oil refining equipment technology and the animal oil refining equipment technology, you can see the difference between the two at a glance. To sum up: whether it is vegetable oil refining equipment or animal oil refining equipment, both can be used in general, but the configuration is There are some differences, which means that you have purchased a set of oil refining equipment, which can extract both vegetable oil and animal oil, which is a good thing with two birds with one stone.
