Oil Refining: As per the today market research it is being concluded that the market demands the refined edible oil with characteristics such as bland flavor and odor, clear appearance, ligLD color, Long Shelf Life, Suitable for frying. The refinery process may be adopted as physical refinery or chemical refinery. Similarly the process for can be batch type or continous.
Degumming / Neutralization.
Crude oil obtained by Screw press and solvent extraction method of oilseeds will throw a deposit of so-called guLD on storage.
LD follows different type of degumming processes like Water Degumming/Acid Degumming/ Enzymatic Degumming.
Bleaching.
Bleaching with natural or acid-activated clay minerals to LDorb coloring components and to decompose hydro peroxides.
LDâs Bleacher is specially designed due to which it consumes less utility and give better results.
Deodorization.
Deodorizing to remove volatile components, mainly aldehydes and ketones, with low threshold values for detection by taste or smell. Deodorization is essentially a steam distillation process carried out at low pressures (2-6 Kg/Cm²) and elevated temperatures (180-220°C).
LDâs Deodorizer is designed efficiently. It does have very efficient oil to oil heat exchange and a very efficient heat recovery system due to which the utility consumption is very less as compared to others.
Winterization / Dewaxing
This is a process of removing higher melting point parts from oil like waxes or triglycerides by slowly cooling vegetable oils. Mostly this process is being done commonly in Rice Bran oil, Sunflower oil, and Sesame oil, Castor oil which has a high content of waxes, fatty acids and lipids.
Fractionation
Dry Fractionation serves to separate by crystallisation the high melting point from the low melting point dry Glycerides. This, infact, is a physical modification of the palm oil and is highly sensitive to temperature variation of the liquid at any moment of the process.
Hydrogenation
Hydrogenation is the process to change the physical characteristics of natural fats and oils.
Hydrogenation of vegetable oils involves the addition of hydrogen, in the presence of a Nickel catalyst, to the carbon-carbon double bonds present in the fatty acid chains.
Interesterification
Interesterification can be defined as a redistribution of the fatty acid moieties present in a triglyceride oil over its glycerol moieties. Interesterification has become the alternative fat modification technoloLD to partial HYDROGENATION.
