In its crude form , the vegetable oil is permeated with impurities. These must necessarily be eliminated not to not only make it edible, but also to enhance the color, texture and taste and prevent rancidity. The multi stage refining process in the vegetable oil eliminates these impurities & is sufficiently enhanced to attract consumers for its taste and acceptability to earn greater returns. The crude oil must necessarily undergo the refining process to remove the inherently harmful elements for human consumption including free fatty acids (FFA), gums, sediments, odoriferous and coloring materials present to make the oil edible.
MECTECH has 360o capabilities in the area and provides concept to commissioning expertise that ensures not only glitch-free installation but free flowing vegetable oil production for recurring long term returns. Mectech relentlessly pursues client delight by ensuring greater returns through extreme customization of plants and optimizing processes. Through inimitable innovation and customization, the company value adds optimization into each process to enhance the processes and returns.
THE PROCESS
The oil needs to undergo the processes of neutralization, bleaching and deodorisation, to be made safe and fit for human intake.
The various steps undertaken for refining vegetable oils are:
Degumming / Neutralization
The process of eliminating the embedded phospholipids in order to enhance its physical stability and facilitate further refining is called degumming. Phospholipids turn the oil lead dark and even off -flavor. Free fatty acids, pigments and other impurities are also partially removed by degumming.
Continuous Bleaching
“Bleaching” is the selective elimination of pigments and impurities through interacting it physically and chemically with an adsorbent in order to enhance its quality. It eliminates various impurities like Color pigments, Dirt, Trace metals, Removal of polycyclic Aromatic compounds, Phospholipids.
Deodorization
In this vacuum stripping process, a given amount of a stripping agent (usually steam) is passed for a given period of time through hot oil at a low pressure. The physical process removes various volatile components.
THE MECTECH ADVANTAGE
Degumming
Mectech has revolutionized the degumming processes by incremental enhancements. These processes are customized according to the methods of processing, chemicals used and the content of phosphatides in the crude vegetable oil.
Bleaching
MECTECH’s customized design of bleacher eliminates the need for mechanical agitation. Hence bleaching is accomplished under optimum conditions of moisture content to achieve perfect results ensuring power consumption saving for the entire system.
With the absence of mechanically agitated bleacher, the quality of oil improves due to lack leakages from gland system.
Also eliminates maintenance costs arising out of wear and tear as the Mectech bleacher is maintenance free.
Mectech’s customized bleacher also ensures that the bleaching earth remains under suspension thus avoiding dead areas, resulting in lower consumption of bleaching earth.
Due to the bleaching process being executed under controlled parameters, better and consistent quality of resultant oil is guaranteed, that is crucial to its marketability.
DEODORIZATION
The customized Mectech designed oil-to-oil heat exchanger fitted in the last tray of Deodorizer is optimally efficient to ensure minimum heat energy requirement.
The elaborate and efficient design of fatty acid scrubbing recovery system ensures virtually no transfer of fatty acid into barometric condenser.
The custom designed heating coil by Mectech prevents charring of oil during the process.
