Ever Wondered How Oil Is Produced?

Have a look at the video to understand the process

 

First section is cottonseed pre-processing plant. In this section, cottonseeds are cleaned and their cottons were collected. Afterwards, linters are removed from cleaned cottonseed and collected. These linters are classified into two types – first type of linters is big in proportion and called first cut cotton linters and another type of linters, which are fine and collected in second cut. It is called second cut cotton linters. This second type of linters (second cut cotton linters) are used in vast proportion to make various types of things such as high quality papers, Artificial silk, Currency note, Absorber dent cotton, Rayon, Methyl cellulose, Nitro cellulose Gum cotton, Bullet of riffles, various types of plastisizers as well. After collecting cotton- lints; seeds and cover leaf are separated by DECORTICATOR Seeds are used for Oil manufacturing and cover leafs are usually used as animal feeds. 

Second section oil mill, where it results into oil by pressing seeds with Expeller. Even the De-Oiled Cake, which left during the process, contains 7 to 8% oil. This De-Oiled Cake is called Expeller De-Oiled Cake. So in this section De-Oiled Cake as well as oil are produces, which then are taken to refinery for rectification (distillation).

Third section is Solvent Extraction Plant, where oil extraction is carried out from De-Oiled Cake during this process; Heczin (one type of petrol) is sprinkled upon De-Oiled Cake, which extracts oil from De-Oiled Cake. Then Heczin-petrol being given high temperature gets transferred into vapour, and then it is to freeze. It results into the form of petrol once again, that is the produce to reuse. The remaining crud oil (Solvent Extraction Oil) is taken to refinery for its distillation.  

Thus, the prepared oil is called “ washed oil” this ‘washed oil’ is directly used to prepare  “Vanaspati Ghee”. To prepare edible oil, it is yet to be refined & processed. In the first phase to this process, the oil is processed with two elements – “ Fullers Earth & Activated Carbon” in equipment named ‘Blicher’ to remove its colour. Then, the oil is taken for filtering once again, to make it odourless it is processed in Deodorizer. Presently, this process is done by vaccum to increase the temperature of oil and remove the odour. After then, it is to be freezed, in order to freeze the oil, it is passed through heat exchanger. Then two vitamins – vitamin A & D are added into the oil. Ultimately which form of oil, we get through the whole procedure is known as Cottonseed Double Refined Oil. 

Cottonseed is the only thing in Telibia, from which maximum by-products can be gained. In cottonseed processing mainly five by products are: Cotton linters Hulls Cottonseeds De-Oiled Cake (Khor) Oil Soap stock
