Edible oil is an important primary food and requires highest degree of product quality. The final product quality depends on the refining method and the nature of the raw oil. Fenix® offers a wide range of solutions designed to boost value in this respect.
The crude oils are de-gummed and the free fatty acids are then removed by distillation in one stage during deodorizing. (Some oils like cottonseed oil or fish oil are not suitable for physical refining.)
The oil discharged from expeller presses has certain solid content or gum, the level varying on the oil seed, which must be removed. For easier separation, the solids are wetted with hot water and separated along with hydrated phosphatides in the decanter/clarifier. The solids are returned to the press for recovery of adhering oil. The clarified oil is then either refined directly or dried under vacuum for storage or consumption.
Fenix® “CentriMix” Process for De-gumming, Neutralising and Washing is designed to handle a multitude of oil feed stocks. It is followed by the Fenix FlexiBleach Process which reduces the bleaching earth consumption by 20 to 30%. We also have a newly developed technology - Fenix FlexiBleach with Pre Filtration – based on the reuse of the spent bleaching earth without removing it from the filters. Once the spent earth is reused in the filter, it is discharged and evacuated.
The final step in refining is the innovative Fenix Eco2Flex Deodorisation. Its efficient scrubbing system minimises fatty matter carry over and water pollution. Efficient plug flow “HiVac Heat Exchangers” enhances economy. It is flexibile to process high FFA oils by physical refining and gives vary high stripping efficiency due to the use of cross flow column. Control for optimizing tocopherol and minimizing trans acid generation is built-in. The mechanical “free end” prevents thermal fatigues in heating/cooling tubes. The efficient design ensures 100% draining and cleaning. It is a new, fully integrated and compact deodorising system including the concept of steam injection in which deaeration, heat exchanging, heating/stripping, cooling and scrubbing take place in a controlled environment.
The process is the result of a continuous effort based on the experience of more than 300 deodorising plants.
In a nutshell Fenix Edible Oil Refining gives very short payback period due to:
??? Superior product quality
??? Minimum hydrolysis & low loss of Oil
??? Highest level of heat recovery
??? Reduced utilities (Stem, Diesel/Power, Water, Chemicals)
??? Reduced installation cost
??? Reduced maintenance cost, Limited & easy maintenance
??? Easy supervision
