We have enough experience and advanced machinery for making soybean oil, which lead the technicity in this field.

The rude oil from oil press or solvent process, which should be refined for better edible oil.

The capacity is from 5t to 1000t per day.

1. OIL PRE-TREATMENT PROCESS:
The soybean could directly extruded, then go to solventing process, so it could save more investing cost. We suggest the clients to use this process better.

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 50 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.
4. The final cake is processed for the soy protein better, to get the higher profits.

Note: We have the different oil mill factory for the visit.

We supply for the turn-key project now and then.
