Edible Oils

Oils are one of the main ingredients of the worlds mostly cooked recipes. They enhance the taste due to which the overall experience of the meal becomes memorable forever. Needless to say, these oils have become an integral part as a cooking medium in all the cuisines. However, any natural or manmade ingredient is infused with good and bad elements that are to be taken care in right level and right time. Oils too come with both the elements.

To get rid of unwanted ingredients and make it fit for human consumption, oils are treated in state of art ultra modern fully automatic plants into various intensified steps.

 

Seed Crushing

Seeds are cleaned to remove impurities like Stones, Broken Seeds, Husks etc., cleaned seed are charged into hoppers through chain conveyor.

Seeds are crushed in the process, temperature is controlled to maintain the pungency of oil. Oil & Soy or Mustard cake are obtained from this process.

The oil cake so obtained is pressed in expellers to remove further oil.

 


Solvent Extraction

The Oil cakes obtained from expellers are cleaned to remove impurities like husk, stone particles etc, through pre cleaner and destoner which are further fed to the Cracker Breaker to make small pieces.

These cakes are then fed to the solvent extractor. In the solvent extractor food grade hexane is sprayed through the cake to extract the oil content (7 to 9%) out of the cake.

In case of Soya Bean, dehulled seeds are cracked and adjusted for moisture content and then subsequently rolled into flakes, expanded.

These flakes are then fed to the solvent extractor. In the solvent extractor food grade hexane is sprayed through the cake to extract the oil content (17 to18 %) out of the flakes.

This wet DOC is further fed to De solventiser Toaster to evaporate hexane particles and oil particles.

Output of the toaster section at bottom is De Oil Cake and is separately collected, conveyed and packed in Gunny Bag or PP bag.

Evaporated particles/ Miscella (mixture of oil and Hexane) is fed to distillation and recuperation section to depart oil and hexane.

This recovered hexane is recycled in the process.

Solvent extracted raw grade oil is required to go through degumming and refining to produce refined oil.

 


Degumming

http://www.gokulgroup.com/portals/0/images/arrow.gif

Crude oils having relatively high levels of phosphatises may be degummed prior to refining.

http://www.gokulgroup.com/portals/0/images/arrow.gif

The process generally involves treating the crude oil with a limited amount of water to hydrate the phosphatises and make them separable by centrifugation.

 


Refining

http://www.gokulgroup.com/portals/0/images/arrow.gif

The process of refining (sometimes referred to as "alkali refining") generally is performed on vegetable oils to reduce the free fatty acid content and to remove other gross impurities such as phosphatises, proteinaceous, and mucilaginous substances.

http://www.gokulgroup.com/portals/0/images/arrow.gif

By far, the most important and widespread method of refining is the treatment of the fat or oil with an alkali solution. This results in a large reduction of free fatty acids through their conversion into water-soluble soaps.

After alkali refining, the fat or oil is water-washed to remove residual soap.

This oil is further bleached to remove colour producing substances

http://www.gokulgroup.com/portals/0/images/arrow.gif

Bleached oil is Deodorized, a vacuum steam distillation process, for the purpose of removing trace constituents that give rise to undesirable flavours, colours and odours in oil

 


Hydrogenation

http://www.gokulgroup.com/portals/0/images/arrow.gif

Hydrogenation is a process by which hydrogen is added directly to points of instauration in the fatty acids.

http://www.gokulgroup.com/portals/0/images/arrow.gif

In the process of hydrogenation, hydrogen gas is reacted with oil at elevated temperature and pressure in the presence of a catalyst.

http://www.gokulgroup.com/portals/0/images/arrow.gif

The catalyst most widely used is nickel supported on an inert carrier which is removed from the fat after the hydrogenation processing is completed.

 Soya De-Oiled Cake is a free flowing coarse granular material, produced from cleaned soybean seeds after series of preparatory physical processes followed by multistage extraction.

http://www.gokulgroup.com/portals/0/images/arrow.gif

Soya Bean  De-Oiled cakes are used as cattle feed.

http://www.gokulgroup.com/portals/0/images/arrow.gif

Soya De-Oiled Cake  is manufactured from NON-GMO- soya bean seeds, under highly sophisticated multistage hygienically controlled plant

Soya De-Oiled Cake  is highly  protein  and are free from cholesterol

 

Castor De-Oiled Cake

 De-Oiled Castor Cakes are excellent product used for organic fertilizer.

http://www.gokulgroup.com/portals/0/images/arrow.gif

Detoxification of castor cake is made by the treatment of calcium hydroxide, sodium bicarbonate and autoclaving (15 PSI For 30 Min) – after detoxification it can be used as an animal feed.
