Cooking Oil Refinery

Product Details

Unlike batch oil refining process in which oil is processed in measured batch, in Continuous Vegetable Oil Refinery, crude oil is processed continuously with a constant stream of flow. During the process, necessary chemicals and other utility items added continuously in the measured quantity. There are present foreign impurities such as gums, mucilage and unfiltered proteinous matter from the seed in the crude oil extracted from expellers. It also contains gums which makes the oil unfit for edible purpose.Basic stages of the process are as below:Neutralizing Bleaching Dewaxing & Deodorizing Bleaching Section:In the bleaching section, high vacuum is created in which the neutralized washed oil is pumped into the bleacher vessel for remove excess color from oil Firstly, the oil is heated for complete removal of excess moisture and post that, it is treated with measured quantity of bleaching earth & activated carbon Later on, the oil passes through a filter media (pressure leaf / filter press) for the separation of spent bleach earth and bleached oil.From bleaching section, the oil obtained is clear golden in colorDewaxing and Winterisation (Fractionation):With this Dewaxing and Winterization (Fractionation), the oil produced is clear and brilliantly refined oil and to meet certain specifications of cloud point.As compared to other oil, sunflower and rice bran oil contain waxes and hence, specially subjected to de-waxing process called Winterization Plant. Through this process, the oil is get separated from waxes thus producing sparkling good quality edible oils.For the complete removal of wax from oil, firstly, the oil is first processed in crystallizer where cooling is done by chilled water circulation. In this process, crystals are formed from the wax and after this, it is passed through the filtration process. Post wax separation, the de-waxed oil is collected.For uniform cooling and effective nuclei growth of particle, the crystallizer designed geometrically.Deodorizing Section:This process ensures the improved quality of oil with its enhanced shelf lifeDirectly charged to deodorizer or through heat exchanger, the bleached oil is heated under high temperature and high vacuum to obtain odorless clear oilPost processing, the extracted oil obtained is odorless and light in colorIn order to obtain sparkling light color and odorless oil for packing, post cooling, the oil is passed through polishing filterDry Fractionation:Our expertise lies in providing low operating cost fractionation plant that is designed for producing high olien and soft stearin yields. This plant is PLC programmed for efficient working and reliability.In rotary vacuum drum filter, the continuous separation of stearin and olien is carried out. In comparison to this process, crystallization process works on the perfect principle of developing and growing particles size for easy smooth separation of Stearin and Olien.Hydrogenation:Also known as fat modification, Hydrogenation involves a unique 3 phase process system comprising of solid (nickel catalyst), liquid (oil) and gas (hydrogen). Further a selective reaction, by bringing gas-hydrogen, liquid-oil to the solid-Ni Catalyst and this technological concept formalized an Engineering Design. We offer hydrogenation / fat modification plant, which have several benefits.
