MY FAVORITE TECHNOLOGY
Technology is the word that refers to the advancement, then it may be conversion of telephones to mobiles, keypad mobiles to android and so on. Though we are talking of advancement, but exactly what does technology means? First let us see what Technology is and then I will tell you about my favourite technology.
Technology is the sum of techniques, skills, methods & processes used in production of goods/Services or in accomplishment of objectives such as scientific investigation. Since we’ve seen what technology is now I will tell about my favourite technology. My favourite technology is the Technology of oils, fats and Surfactants. In This Technology, the study is related to Vegetative oils, which includes, their study, extraction, refining, wide range of applications, etc. Being an engineering student after 12th, I always wanted to do something unique, to study something unique, rather than core branches. Hence I decided to go with this technology after 12th and started my career as B.tech in technology of oils, fats and surfactants. As I started studying about this technology, I came across wide variety of information like what are edible oils, non-edible oils, how the oil is extracted from oilseeds, how the refining is done, it’s applications and so on.
Since ancient times man has known how to remove vegetable oils & fats from their natural resources and put them to his own uses. The crushing of oilseeds has been practiced in India since time immemorial with use of bullock driven Ghanis. Ghani oil industry is an age old industry in India. At the beginning of this century, there were 5,00,000 persons employed in pressing oil with the aid of ghanis. However, the employment in this unorganized, decentralized, village-based industry declined with adverse rotaries, hydraulic presses and expellers after thirties. The oil milling industry in India may be divided into three groups, these are: Ghanis (manual/animal driven or small power driven), large oil mills using presses and extractors and plants using solvent extraction techniques.
After 1951-52, the ghanis become less important and use of mechanical expellers and Solvent extraction started. Now-a-days these two techniques are mostly used for extraction of oil. If the oil content in oilseed is less than 25% then mechanical extraction is used, but if the oil content is more than 25% then solvent extraction process is used. After the extraction of crude oil it is sent for refining. Refining includes process like Degumming, Neutralization, Bleaching, Deodorisation & Winterisation. Through this phospholipids, FFA, Colouring pigments, odour is removed. Also various by-products are obtained during refining which are sold by company & profit is made.
The products of my technology are as follows:
- Floor cleaners
- Hand Sanitizers
- Hydrogenated fat
- Vanaspati ghee
- Hand washes
- Shower gels
- Emulsifiers & so on.
- Soaps, detergents and Gels: The oil is used in production of soaps, detergents and gels. During the neutralization process in refining, soapstock is obtained which is used in production of soaps, detergents and gels.
- Hydrogenated fat: The partial hydrogenated fat like vanaspati ghee is produced using edible oil. The edible oil is sent for partial hydrogenation of oil in which the hydrogen atoms are added at double bonds and unsaturation is converted to saturation and hence it gets converted to hard fat, known as partially hydrogenated fat.
- Emulsifiers: The Lecithin is obtained as by-product during degumming stage of refining, which acts as an emulsifier in confectionaries, chocolates, etc. It is the most widely used emulsifier in bakery products as well.
- Cosmetics: The oil is used in production of cosmetics. Oil contains fatty acids like stearic acids, palmatic acids using which the base is formed for making of cosmetics.
