CAUSTIC REFINING
MECPRO supplies either the continuous
neutralising installation with centifugal separation of the
Soap Stock or Batch Neutralising System for small capacity plants.

PHYSICAL REFINING
Physical refining is a modern alternative
for processing crude edible oil by steam stripping of the
free fatty acids instead of chemical neutralisation. The advantages
of this new system are :
-
Better yields
-
High Quality of fatty acids as by-products
-
Good oil stability
-
Simultaneous distillation of fatty acids
and deodorisation (Our deacidifier-deodoriser is perfectly
adapted for this operation)
-
Lower cost of equipment
-
Simplicity of operation
-
Prevention of ecological problems
The first stage in the physical refining
process is the complete removal of all phosphatides, resins
and metals out of the crude oil. In addition to the well known
degumming method applied to crude oils containing low amounts
of gums like palm, palm kernel and coconut oil, we have developed
our special wet degumming system to treat most of the crude
oils having a high content of gums such as soyabean, rapeseed,
sunflower and groundnut in order to suit them for the next
stages of physical refining i.e. bleaching and deacidification-deodorisation.
COMBINED PHYSICAL / CAUSTIC REFINING
|
|
The oil produced from our Solvent Extraction Plants is ideally
suitable for water degumming which results in reduced oil losses
and utility consumption in degumming processes and the by-product
can be converted easily into lecithin which is a high value
product. |

CONTINUOUS
BLEACHING
Our continuous bleaching line is
delivered complete with :
- Optional addition of silica
absorbants
- Optional deaeration system
for bleaching earth
- Vertical leaf filters with
automatic cake drop
- Optional complete automation
of the filtration cycle
- Safety filtration
CONTINUOUS DEACIDIFICATION-DEODORISATION
The main feature of our Deacidification-Deodorisation
system is its low steam consumption which is obtained due to
the following factors :
No steam heating of the oil is required because of the high
economy in heat transfer between the hot discharged refined
oil and the cold incoming degummed and bleached oil, 80% of
the total heat required is recovered in a special heat exchanger
supplied in the deacidification-deodorisation system.
The low amount of stripping steam 1-1.5% of the oil processed
results in a considerable reduction of the steam required for
the vaccum equipment. |
