There are two ways to extract vegetable oil: Mechanical pressing and solvent extraction.
The rude oil from oil press or solvent process, which should be refined for better edible oil.
The capacity is from 5t to 500t per day.
1. OIL PRESSING PROCESS:
In the first way, oil pressing plant is composed of seeds cleaning & crushing unit, steaming and drying units, pressing unit, conveyor, electrical cabinet box, etc. The oil pressing unit as the main stage, to make the vegetable seeds flake in a hardened cage to squeeze oil content out.
It's complete set of oil pressing equipment, which is automatically operated to save more labor and cost.
Including to the following machinery and parts:
Electrical apparatus control, materials feeder, conveyer, screening machine, steaming & frying machine, huller machine, medium boilor 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. Solvent extraction will further process these cakes and leave less than 1% oil in the final cake. This method results in higher yields, more oil; Lower power consumption, lower wear & tear / maintenance and high extract efficiency. Thus it could be used as complement equipment to extract the oil remained in cake, which yields are extra profits.
Certainly if the capacity is less than 30 tons, or it is high rate of output oil, this process could be saved.
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. The main equipment of oil refinery is various kinds of vessels and tanks carrying on different tasks with additives. 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.
Note: We have the different oil mill factory for the visit.
We supply for the turn-key project now and then.
