The Process of Refining High quality Oil

1. OIL PRE-PRESSING Process:

It is essential for crushing the oil materials into pieces like rice size if it is dry, then rid off its more moisture if it's fresh.

If you want to make high quality oil, seeds cleaning & crushing unit, steaming and drying units, pressing unit, conveyor, electrical cabinet box are necessary. Oil press unit is used to squeeze the oil out of the oil seeds.

It is automatically operated hence requires less labor and cost.

Including to the following machinery and parts: Electrical apparatus control, supplies feeder, conveyer, screening machine, steaming & frying machine, huller machine, medium boiler etc.

The by-products from the oil press are cake and soap residue. The cake could be used as animal food with our pelleting machinery, or source material for the other way of extraction. Soap residue is the source material for laundry soap with soap making machinery and washing detergent.

2. OIL SOLVENTING Process:

The second way to extract oil for using chemical solvent to dissolve oil content contained in cake or direct oil seeds, only for lower oil seeds, for example soybean. Then oil is separated from solvent by vaporizing solvent out. In configuring the solvent extraction plant, pre-pressing may be involved in which case seeds are lightly pressed, and which leaves about 14% to 18% oil in the pressed cake. The oil content of cakes and leave may be less than 1% in the final cake after solvent extraction. Higher yields, more oil; Lower power consumption, lower wear & tear / maintenance and high extract efficiency are the features of this method. Thus it could be used as complement equipment to extract the oil remained in cake, which yields are extra profits.

You can pass it if the capacity is less than 50 tons, or it's high rate of output oil.

3. OIL REFINERY Process:

The crude vegetable oil from above mentioned two ways of extracting, oil pressing and/or solvent extraction, will be pumped into oil refinery units to produce cooking oil at various grades.

For oil refining, various kinds of vessels and tanks carrying on different tasks with additives are necessary equipments. These tasks may include sedimentation/filtering, neutralization (removing free fatty acid), degumming, decolorization (bleaching), deodorization, dewax etc. Different combination of steps and the treating degree of each step result in different grade cooking oil and salad oil.
