Edible Oil Refining
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. FenixTM 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.
FenixTM Centrimix� Process for De-gumming, Neutralising and Washing is
designed to handle a multitude of oil feed stocks. It is followed by
the Fenix Flexi BleachTM Process which reduces the bleaching earth
consumption by 20 to 30%. We also have a newly developed technology -
Fenix Flexi BleachTM 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 Eco2FlexTM
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 oils containing high FFA
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.
