palm oil refining industries are one of the most important manufacturing sectors in the world. Palm oil has become an increasingly important vegetable oil in the world market and currently it is one of the largest traded vegetable oil in the world. Indonesia & malaysia are the largest producer and exporting company of crude palm oil.
crude palm oil is obtained from mesocarp part of palm oil. Extracted crude palm oil contains some undesirable impurities and these impurities need to be removed partially or completely through the refining process in order to produce good edible oil with better stability and keepability.
currently, palm oil is a popular cooking oil in some tropical countries like south east asia, africa, and some parts of brazil. Its popularity is due to its higher heat resistance as compared to any other vegetable oils and also because of its lower cost and good oxidative stability.
Fractionation is the process where the crystallization of saturated triglyceride takes place in a mechanical equipment called the crystallizer. Crystallized oil is further passed through a lter where separation of solid and liquid phase takes place. Solid phase remains in the chamber. Liquid phase comes out through the taps and is collected in the storage tank.
Entire process takes place in several steps which including: Oil heating, oil charging, and crystallization, ltration, squeezing and cleaning of lter.

Despite being GM oil, canola oil scores high for coronary health as it contains less saturated fat than any other oil. It is higher in the omega-3 fatty acid, alpha linoleic acid (ALA) that is important to intake in the diet.
It is well known that Oil is ester of Glycerol and fatty acids, which can be decomposed in to their original constituent (Fatty acid and glycerol) or synthesized in to Triglycerides by Fatty acids and glycerol.
AbstractGlycerolysis reaction is reverse of Hydrolysis process. It is carried out by reacting fatty acids with glycerol. In addition to esters, water is also a product of Glycerolysis. The reaction is reversible and proceeds to completion only if water is removed from the medium. The equilibrium between the forward reaction (Glycerolysis) and the reverse reaction (Hydrolysis) is controlled by water content of the reaction mixture. In the presence of excess water, hydrolysis predominates, whereas under water eliminating conditions Glycerolysis is favored.

Vegetable oil is heated to the desired temperature in a multi-compartment Vacuum Heater with counter current ow of vegetable oil and heating medium i.e. High Pressure Steam or Thermic Fluid.
Pre-heating is gradual and methodical so that all of the oil comes in contact with this sparging system at the free surface exposed to vacuum.
Packed Column with packings of large surface area is provided on the top of Deodorizer. This ensures reduction of Free Fatty Acids to the desired level.
An additional top heating tray is provided below the Packed Column to compensate for the unavoidable loss of heat due to evaporation of Fatty Acids.
Perfect deodorization is accomplished by providing large free surfacing area contact between oil and stripping steam at an absolute pressure of 2 m bar. This results in furnishing oil surface layer of numerous bubbles having 5 - 10 mm diameter. These small bubbles burst and they discharge the water vapour saturated with distilled fatty acids and the odoriferous compounds. These ascending vapours are immediately and freely taken out into lateral ducts through the large section opening provided on top of each stripping tray. This ensures virtually no pressure drop from top to the bottom tray.
This system is included in the Deodorizaon system to improve the FFA of Fay Acid Disllate. FFA of fay acid disllate in palm oil deodorizaon is about 88-89%.
AdvantageThe close loop water cooling system is introduced in the Deodorizer and has the following advantages:

Hydrogenation is the process to change the physical characteristics of natural fats and oils. Hydrogenation of vegetable oils/fatty acids involves the addition of hydrogen, in the presence of a Nickel catalyst, to the carbon-carbon double bonds present in the fatty acid chains. Salient features
Acid oil is produced by spling of vegetable oil soap stock with sulphuric acid or hydrochloric acid. Spling process can be performed either in batch or in connuous process, but considering the producon cost and quality of acid oil, connuous process is more economical then the batch process.
lnteresteri?cation process is random chemical process is the most general applied. The best known catalysts are alkali metals such as sodium, potassium and their alloys and alkoxides such as sodium methylate or sodium ethoxide. Fatty acid neutralization and drying is therefore necessary prior to the addition ofthe phosphoric acid.
Glycerine is a ubiquitous substance that is widely found in nature and has a broad range of uses ranging from Cosmetics to Food Products. Mectech has long experience in the Oils & Fats and OleoChemical industry sectors which has long been associated with the production of Glycerol as a by-product. Plants executed by Mectech produce Glycerol by the following means the Transesterification of Methyl Esters, from Fats Splitting and by Saponification which is used to produce soap.
The Glycerine / Sweet Water purification and evaporation allows maximum recovery and pre-treatment before evaporation to produce Crude Glycerine. The pre-treated sweet water is concentrated in Triple Effect or Quadruple Effect Evaporation systems under vacuum. The use of multiple effects reduces the requirement of steam.
Fatty Acid industry is associated with production of fatty acids and glycerine. Both vegetable oils & animal fats are being used as feedstock for fatty acids / glycerine manufacturing. The fatty acids are manufactured as a distillate mixture or a pure fraction. Pure fractions can be obtained either from fractionation plant or by selectively choosing the feed-stock & carrying out straight distillation.
As name suggests, expellers are mechanical machines used to expel / separate oil from the oil-bearing seeds. Now a days most of the expellers consists of screw type shafts enclosed in a perforated cylindrical chamber, hence the expeller is also called as Screw Press.
In a typical screw press, the feed material fed at the one end of the screw shaft and the De-oiled cake/Press Cake is collected the opposite end of the screw shaft, as the feed material travels in the annular space between screw shaft and perforated oil chamber, the oil seeds are subjected to high mechanical pressure which results in rupture of the oil cells. The oil separated from the seed, seeps through the perorations in the oil chamber and the defatted/pressed cake is collected at the opposite end of the shaft.
