Solvent extraction process of soybean oil solvent extraction plant

Soybean 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, cooking oil solvent extraction technology has become the most advanced production technology in the international edible oil processing field.

Soybean oil solvent extraction plant

* Soybean oil solvent extraction plant application

Solvent extraction 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.

* Unique features of doing company soybean 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.

* Main process of soybean oil solvent extraction plant

A complete engineering & technology service in whole edible oil solvent extraction process including:

Pre-treatment Process----Pre-pressing System----Edible Oil Solvent Extracting System---Edible Oil Refinery System---- Winterization System -----Edible Oil Packing System

1. Pre-treatment Process

Pretreatment Equipments which is used to pretreat the raw material include: shelling and husking equipment, Sieving equipment and roasting machine.

2. Pre-pressing System

Prepressing Equipments include: oil prepressing equipment, Steam and frying machine. This step is to press the raw material into crude oil.

3. Solvent Extracting System ( Extracting Equipment, Desolventizer Toaster )

Solvent extracting is the core process for a complete soybean oil solvent extraction plant, which uses organic solvent through soaking or spraying contact methods to extract oil from oilseeds. The materials(for pretreatment) are sent to rotary extraction by the scraper conveyor, extracted by the solvent so that oil fats can be dissolved. After this step, you will get meal and mixed oil. After that the meal is sent to the toaster, through which the solvent will separate from the meal. Then the solvent goes to condenser and is recycled to rotary extraction. Consequently, after the solvent is completely evaporated and left with purified oil fats, the crude oil is gained.

4. Oil Refinery Equipment (Oil pump, Oil filter, Decolouration )

However, the crude oil still can not be used for human diet due to various impurities produced by the leaching process. Because some purities are extremely harmful to human being. So it is necessary for further processing which we call it refinery system. This processing system including degumming, neutralization, decolorization and distillation deodorization. After a serious of purify and process our edible oil is made.   

5. Oil Filling & Packing

Packing is the final process. You can choose different packing methods according to the clients’ encapsulation demands, like jar packing or barrel packing. The packing method should consider the principle that is convenient and cost-saving for transportation.

Loop type extractor for soybean oil solvent extraction plant

The advantages of vegetable oil solvent extraction plant:

First is high oil output.the oil residue of screw pressing way can be higher than 5％．But the oil residue of extraction way will be lower than 1%.

Second is extraction way has less cost,high oil yield,high efficiency,better working stability,easy operation etc advantages.
