High efficiency edible oil solvent exctraction plant

Edible oil solvent extraction plant is the second step in edible oil processing machine. Product (cake from cooking oil press section) is carried into solvent extraction plant. There are still much oil in cake.Edible oil solvent extraction plant is a kind of oil leaching through soaking or spraying pre-pressed cake by a certain organic solvent, which adopts the chemical leaching oil process. The principle of this part is the different solubility of solvent. Based on the competitive advantages in both structure and utilization, edible oil extraction technology has become the most advanced production technology in the international edible oil processing field.

Application Of Edible Oil Solvent Extraction Plant:
Solvent extraction plant fits for pre-press extraction of high-oil-content materials like sesame seeds and second time extraction of oil cake produced by low-oil-content materials like soybeans.

Features of Edible Oil Solvent Extraction Plant:
(1) High oil yield rate and obvious economic benefits.
(2) Low residual oil rate in the dry meal and oil cake.
(3) Low consumption and high productivity.
(4) High automatization.
(5) Latest design, excellent quality and professional installation team.

How to manufacture soybean oil by solvent extraction method?

Soybean oil solvent extraction method is to use solvents like N-hexane to extract more oil out from processed oil seeds or oil cake. By this way, the final oil residue will be lower than 1% and the meal is more suitable for animal feed, so you can get more profit from it. Now more and more clients choose this kind of processing technology for soybean oil processing.

Usually the oil content rate of soybean is around 17%, that is why our clients tend to choose soybean oil solvent extraction method to process soybean when input capacity is above 30tons per day. Soybean oil solvent extraction method contains four main parts:

1. Soybean solvent extraction part: using N-hexane to react with oil seeds or cake, in order to extract more oil out, after the soybean oil solvent extraction method, you will get two parts: first is the mixture of solvents and oil called miscella oil; then is the mixture of solvents and meal called wet meal.

2. Wet meal DTDC system: DTDC means desolventizer, toaster, dryer and cooler, which is mainly used to separate the solvents from the wet meal, then the dried meal will be sent to meal silo for storage.

3. Miscella oil treatment part: since miscella oil contains solvents, we need to separate the solvents from the crude soybean oil by first evaporation, second evaporation and stripping tower, then we can condensate the oil and pump it into crude oil tank, and you can choose to sell the crude oil to refinery factory or you can add a soybean oil refinery plant by yourself.

4. Solvents recovery part: Usually producing one ton crude soybean oil through the soybean oil solvent extraction method needs around 4kg solvents. Considering of cost-effectives and environmental protection, we add this system to recycle the solvents by condensing it and collecting it for reuse.

In fact, we have built this soybean oil solvent extraction plant in different regions and countries. Last time one of our old clients in Africa gave us feedback that by using the soybean oil solvent extraction method, and now his profit is much higher compared for just using single pressing method before. So if you are also interested in the soybean oil solvent extraction method, please contact us for more details.

Soybean oil pressing machine and soybean oil solvent extraction plant

 According to the oil extraction methods, soybean oil processing machine is basically divided into two types, soybean oil pressing machine and soybean oil solvent extraction plant. Generally, the soybean oil pressing machine is suitable for both small scale and large scale cooking oil production line, while, the soybean oil solvent extraction plant is more suitable for large scale or industrial scale vegetable oil processing plant.

Small scale soybean oil pressing machine

After processing by soybean oil pressing machine , the residual oil rate in cake is around 7%-8%. After processing by soybean oil solvent extraction plant,  the residual oil rate in cake is less than 1%.  The residue of solvent extraction plant is less than one percent. The users at that time can get soybean meal which contains high protein and can also be used for making the feed of animal. Due to this, lots of people are very much interested in solvent extraction plant of soya oil.

How to make soybean oil from soybean seeds? How many types of extraction method can be used in soybean oil processing process?

In general, there are two methods for extracting soybean oil: one is mechanical extraction method, also called traditional soybean oil extraction method; the other is solvent extraction method, also known as chemical extraction method. Both mechanical extraction method and solvent extraction method all can achieve the goal of effective extraction of soybean oil.

Soybean oil extraction machine

The difference between mechanical way of soybean oil extraction and chemical way of soybean oil extraction is that: the mechanical extraction method is simple in operation, small in area, but the residual oil rate is high, and the residual oil rate is about 7% to 8%. Soybean oil solvent extraction methods are relatively complex, but the residual oil rate is low , the residual oil rate is less than 1%. You can choose one depending on your capacity and your fuel needs, or you can use two together.

Mechanical extraction method:
The mechanical extraction method refers to a machine that extrudes soybean oil from soybean by increasing the temperature and activating the oil molecules by means of the action of mechanical external force. The mechanical extraction method is suitable for family workshop or small soybean oil mill (1-30 tons). The most commonly used soybean oil press machine are: single screw soybean oil press machine, intergrated soybean oil press machine with filter.

Solvent extraction method:
Soybean oil solvent extraction, also known as "extraction", is a process in which oil is extracted from an oil with an organic solvent. Soybean oil solvent extraction method is suitable for large edible oil processing plants (over 30 tons). Soybean oil solvent extraction plant is as follows:

2.Solvent extraction of the soybean oil processing plant:

Soybean flakes →  Extractor →  Desolventizer Toaster →  Stripping Tower (Oil Stripper) →  Crude Soybean Oil

Soybean oil solvent extraction process flowchart

The pretreated soybean flakes are sent to soybean solvent extraction plant. The plant uses a kind of solvent(normal hexane) to absorb the oil from soybean, and then the machines separate the solvent from crude soybean oil, solvent is used for recycling and crude soybean oil is refined by refinery plant.
