Solvent Extraction is a practice done to extract the oil from oil bearing materials with the use of Solvent. Solvent being used in this process can be normal Hexane – a petroleum by-product. The plant designed by us extracts the oil directly from various oil seeds which contain less than 20% oil. After detaching, it is fully pressed to make it a cake of seeds containing more than 20% oil and then the oil is extracted from it. The seeds of sunflower, peanuts, cotton seed, palm kernel, canola, copra, castor are used to extract the oil.

Troika’s verified design is simple, robust and flexible for process material and with inherent safety features. The extractor is horizontal in design a concept with universal approval; in fact most of the extraction plants working through out the world have adopted horizontal design of extractor. Adequate capacity condensers and vent air stripping system is provided for recovery.

Refining vegetable oils is crucial to make sure that gums, waxes, removal of gums, waxes, phosphatides and free fatty acid (F. F.A.) are removed from oil.

Batch Refining Plant
The equipment involved in batch refining plant are Neutralizer, Bleacher, Deodorizer, Heat Exchanger, High & low vacuum equipment & Filters.

Continuous Refining line
Pretreatment / De gumming Section:-
Oils are given acidic treatment so that gums are precipitated and separated out by centrifugal separation.

Neutralising Section:-
Here the pretreated oil is subjected to Alkali Refining.

Bleaching Section:-
The neutralized oil is treated with bleaching carbon for removal of coloring pigments.

Deodorization Process:-
This process is meant for removal of odor.

De waxing Section:-
It is essential to remove waxes previous to bottling and marketing of oil and hence they undergo dewaxing session.

Physical Refining:-
The Free Fatty Acid (F.F.A.) present in oil is distilled at elevated temperature and vacuum.

One needs to take care when the oil is expelled to be sure that maximum oil recovery is done with minimum power consumption. Cake should not be burnt as the protein could be damaged; color fixation of oil should not take place, minimum heat should be generated while expelling; moisture should not get along with oil, filtration should be done so that no cake particles remain in contact with oil, thus FFA of oil should not increase.
Our designed equipments take care of all these aspects. Well-designed plant layouts, trouble free maintenance, ease of operation, low utility consumption makes Troika oil mill a viable proposition.

The Process of cattle feed manufacture is comparatively simple process once the formulation of feed mixture is arrived at. The main aim of the process is to ensure that the final mixture contains uniformly same proportion of the ingredients even in smallest possible sample of, say, one gram as originally intended. This is necessary because :

The animal gets uniform daily (or periodic) dosages of nutrients as prescribed by the scientific standard feedings.

Over concentration of any one particular ingredient in a feed portion may render it implantable to the cattle and they may reject further feedings by taking a " once bitten twice shy" attitude.

Obviously, to attain uniformly in concentration, a mixture of ingredients is to be ground to fine mesh and mixed thoroughly. This mixed powder can be used directly for feeding. Alternatively , the mixed ground material can be pelletized. the advantages of pelletizing are:-

The psychological advantage with the buyers as the pelletized material infuses more confidence in them as something having been made scientifically.

It is not possible for the dealers to adulterate the pelletized product with cheaper materials. Therefore, the brand name remains untarnished.

Animals, especially cud-chewing type, like to grind the pellets while eating instead of just swallowing powdered feed.

Wastage in transit of pelletized material is much less than that of powdered material.

The birds fed with small pellets find it easy to pick them with their beaks, while they cannot pick up all the powdered feed, so that wastage in the case of pellets is much less

As the material is required to be heated with the steam before pelletising the feed mixture gets sterilised in case the raw material has been contaminated.

Everyone know oils and fans as an ingredient of daily food or perhaps as a raw material for soap making. But only a few people know them as a group of organic compounds called 'Fatty Acids'. Fatty Acids, in their turn are formed by union of several carbon atoms in a straight chain with hydrogen and oxygen atoms. A single chain may contain anywhere from 6 to 24 carbon atoms, but the common one are 12,14,16,18 and 20 carbon chains. A fatty acid is said to be saturated when all the carbon atoms are combined with hydrogen is incomplete and there is possibility of further addition of hydrogen. Higher the unsaturation lower is the melting point of fatty acid. as such, many oils containing un saturation remains as liquids at normal temperatures. those which contain lesser amounts of unsaturated acids exits as solid or semi solid fats at normal temperatures. A liquid oil can be converted to a required degree of hardness by reducing its un saturation by controlled reaction with hydrogen.

Vanaspati is a product obtained by such controlled hydrogenation of edible liquid oils (called 'soft oils' in the industry), so that its hardness, consistency and grainy appearance resemble natural ghee. The addition of hydrogen to an oil occurs when the hydrogen gas is brought into contact with the oil at a higher temperature in the presence of metallic Nickel Catalyst prepared under controlled conditions. In practice, however the process is not as simple. Several Steps are involved in the process as described in succeeding paragraphs
