What is the solvent extraction ?

Solvent Extraction, as the name suggests is a process to extract the oil from oil bearing materials by means of Solvent, Solvent used being normal Hexane - a petroleum by-product.

Solvent extraction refers to the process of extracting oil from oil bearing materials by means of solvent. Solvent always use a petroleum by-product, usually Hexane. Solvent extraction plant, however, is one of the most important oil plants in the entire oilseed processing.

The whole production line

A complete engineering & technology service in whole Edible Oil Solvent Extraction Production Line 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 Edible Oil Extraction Production Line, 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. Winterization ( Designed for especially cold areas )

 Winterization is also a major part due to some clients’ demands especially for those in the cold climate areas.

6. 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.

The working principle of solvent oil extraction plant 

The material(for pretreatment) is sent to the extractor by the airtight packing auger. The mateiral will be sprayed for extraction by the solvent(Hexance) or mixed oil after they fall into the extractor. The wet dreg(after dripping), falling into the conveyor and be sent to the evapo-separated machine. After steaming, baking and desolventizing, the dreg will be sent to the dreg storehouse. Mixed oil after extraction enters into the first and second long tube evaporator for seperating the steam and solvent, and then flow into the stripping tower for desorption the remaining solvent of crude oil. The extracted oil from the last process will be sent into the crude oil tank for refining plant. The solvent vapors from the extractor, evapo-separated machine, evaporator, stripper tower will be recycled in the cooling system. The solvent after cooling will be collected in the fresh solvent tank for reusing in the process.
