Mini crude oil refining machine equipment for sesame oil refining:
Small oil refining machine is used to process curde oil which is pressed by oil press machine.
This Small oil refining machine have the functions of dephosphorization, deacidification and dehydration.
Through the processes of the oil refinery machine, the product oil can reach the edible standrad.
1.Drew the oil in the tank.
2.Turn on the stirring switch
3.Turn on the heating switch
When the temperature of the oil reaches 65 centigrade, turn off the heating switch.
4.Add hot brine to the oil, sprinkle the hot brine evenly into the oil. Then stir for 15 minutes. Turn off the stirring switch.
Brine/oil : 5/100 ( 100kg oil add 5kg brine)
Salt/water: 5/1000(100kg water add 0.5kg salt)
Note: the temperature of the brine must be 10-15℃ higher than the temperature of 65℃ oil. If the brine temperature is lower than
the oil, the oil would emulsify.
5.Precipitate the oil in the tank for 4-6 hours.
6.Open the switch at the bottom of the tank, let out the precipitate.
Why is Vegetable Oil Refined?
Vegetable and Animal Oils and Fats have impurities such as Moisture, Solids (Insolubles), Gums (Lecithins), Free-Fatty Acids (FFA), Waxes, and Compounds of Sodium, Potassium, Magnesium, Calcium, and other metals. These impurities must be removed to improve the functionality of the oils. Other characteristics of oils (such as Color, odor, and taste) are also considered impurities by modern consumers. These impurities are removed in a series of steps such as degumming (to remove gums), neutralizing (to remove FFA), bleaching (to remove color), deodorizing (to remove odor and taste), and dewaxing or winterization (to remove waxes).
