Oil processing process
1.Cleaning of oil mill machinery manufacturer
In order to obtain high effective cleaning, ensure good work condition and production stability, high efficient vibration
screen was used in the process to separate big and small impurity.
Suction type gravity stoner removing machine was applied to remove the shoulder stone and earth, and magnetic
separation equipment without power and exhaust system were used to remove iron. sunflower oil extraction machinery
Dust removing wind net is installed.
2. Flaking
Flaking means a certainty granularity of soy lamella was prepared for flaked of about 0.3 mm, the oil of raw material
can be extracted in the shortest time and maximum, and residual oil was less than 1%.
3. Cooking
This process is heating and cooking for rapeseed which is easy to separate of oil and can provide the oil quantity from
pre-press machine.It is easy to operate and have long life.
4. Oil press machine
sunflower oil extraction machinery's oil extraction is continuous screw press machine which is suitable
to the plant oil materials which has high oil content sunflower oil extraction machinery.
The instruction of the cake is loose and easy to make the solvent permeate ,the oil content of cake and moisture
used for solvent extraction.
5. Crude oil refining
Oil refining is according to the different usage and requirements, utilizing the physical methods and chemical
processes to get rid of the harmful impurities and needless substance in the crude oil, getting standard oil.
