Continuos Edible Oil Refinery Plant

SpecificationsContinuousType Edible Oil Refinery Plant Neutralizing/Degumming Bleaching Section Deodorizing Section De waxing Section CONTINUOUS VEGETABLE OIL REFINERY PLANTBasic process of refining is same in both batch and continuous refinery. Only difference is instead of a measured batch, crude oil` is processed continuously with constant stream of flow. In between required utilities and chemicals are added continuously in measured quantity. Crude oil` from obtained from expellers, solvent extraction plant contains foreign impurities such as mucilage, gums and unfiltered proteinous matter from the seed. It also contains gums which making it unfit for ediblepurpose. Basic stages of the process are as below:NutralizingBleachingDewaxing and Deodorizing.DEGUMMING AND NEUTRALIZATION SECTION:-The crude oil` is pumped to Neutraliser from oil mill or storage tank and first it is treated with weak solution of phosphoric acid or other suitable degumming agent for removing gums.Thereafter oil is further treated with measured quantity of alkali (NaoH) depending upon free fatty acid (F.F.A.) in crude oil`. In this process soap will be separated.Next process is hot water wash to the oil to remove traces of soap particle andfree alkali.The oil obtained will be light in colour, free from soap stock and called as washedNeutralised Oil. BLEACHING SECTION:- In this process excess colour from the oil is removed. The neutralized washed oil is pumped into the Bleacher vessel operating under vacuum.The oil is first heated to remove excess moisture and thereafter it will be treated with predetermined quantity of bleaching earth and activated carbon.Thereafter the oil will pass through a filter media (Pressure leaf / Filter press) to separate spent bleach earth and bleached oil.The oil will pass obtained after bleaching process is light in colour appearance of oil will be clear golden in colour DEODORIZING SECTION:-This process removes odour from the oil to improve the quality and self-life of oil.The bleached oil is charged to deodorizer directly or through heat exchanger and is heated at high temperature and also under high vacuum in deodorizer vessel to obtain odourless clear oil.Once the process cycle is complete the oil obtained will be odourless and light in colour.After cooling it will pass through polishing filter to obtained sparkling light colour and odourless oil for packing, which will be used as edible oil DEWAXING AND WINTERISATION (FRACTIONATION):-A very simple requirement of this process is to produce Clear, Brilliant refined oil and to meet certain specifications of Cloud Point.Sunflower and Rice Bran oil normally contain waxes compared to other oil. Therefore these oils are subjected to de-waxing process called Winterisation Plant, to remove waxes from oil and to produce sparkling good quality edible oils.To remove the wax, the oil is first processed in Crystal`iser where it is cooled by Chilled water circulation. Where the wax is converted into crystal` form and there after this will be pass through the filteration process. Now, the wax is separated and the de-waxed oil is collectedSHREEJI know-how gives you an arrangement you have been looking for since long. Our Crystal`liser is Geometrically Designed for Uniform Cooling and effective Nuclei growth of particle.HYDROGENATION:-Hydrogenation which is also called Fat Modification is unique 3 phase process system: 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 formalised an Engineering Design. SHREEJI offers Hydrogenation / Fat Modification Plant, which has several benefits
