Introduction Of Edible Oil Solvent Extraction Plant

Edible oil extraction system 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 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.

Solvent extractor is a solid-liquid extraction oil equipment, its basic working principle is: oil materials which are rolled to flakes or buffered slip into exactor and achieve certain material layer height, at this time, solvent (6 # light gasoline) sprays the fuel through the spray pipe, and establish certain level on the material surface layer, at the same time, push oil plants forword uniformly and slowly through the chain scraping driving by tansmission device. When oil is sprayed and soaked over and over again by solvent (mixed oil), fat in oil is slowly dissolved and precipitated, and dissolved in solvent (commonly known as mixed oil). Mixed oil flows into oil measures through the grid plate, then use miscella pump make high density oil into temporary storage, and transport it to the evaporation stripping section. Low density mixed oil continues to participate in circulating spray. The oil content is completely extracted after nearly one hour of leaching, Cleached cake slag are pushed by chain into pulp mouth of the exactor, and sent into desolventizer toaster by wet meal scraper for solvent recovery.
Scope of application: this equipment is suitable for all kinds of raw material leaching, such as soybean germ, rice bran, a leaching. At the same time, it also applies to cotton, rapeseed, sesame seed, tea seed, paulownia seed and exaction of other plant oil pre-pressed cake.

Desolventizing is one of the important procedures in oil extaction plant, as the oil is not edible with the solvent mixed, after the wet meal loaded into the sealed spiral conveyer in the desolventizer-toaster, it gets indirect steam heating in each layer and stirred by stirring-blade, the wet meal is separated by an automatic door in the last layer.
The preheating and desolventizing are performed from the layer-1 to layer7 sequentially. When the meal is fully desolventized with the sprays of direct steam, it is then conveyed out of the oil solvent extraction plant.

Stripping tower is one part of desolventizing equipment in the oil extraction plant, it is the combination of stripper and crude oil tank that has very strong desolventizing ability, the volatile of processed crude oil is greatly reduced to assure the safety of the refining process. It can avoid the unstable residual solvent content in crude oil with no short circuit phenomenon (vapor fluctuations).

The tube condenser is commonly used machine that functions by realizing heat exchange in the vegetable oil extraction plant. It mainly includes the cooling of the solvent steam, solvent & water separation recovery and the recycling of the solvent in the exhaust gas.
Recycling of solvent helps reduce the solvent consumption and production cost, ensures the safety of the production and the quality of the products, two kinds of heat transfer medias can be used to complete counter-current exchanges.
