CONTINUOUS
PHYSICAL REFINING :-
The
final and most important step in process of refining is
the physical distillation/ deodorisation to produce an odorless
and tasteless product with negligible free fatty acid content,
light color and higher stability against oxidation.
The
most economical method of removal of the undesirable components
such as free fatty acids,aldehydes and ketones,fatty alcohols,colouring
compounds etc which are naturally present or develop during
prior processes is by passing the oil through a series of
independent stainless steel compartments positioned vertically/horizontally
within a shell and subjected to intensive live steam stripping
under high vacuum at high temperatures to remove all the
volatiles.
SPEC
offer plant for Continuos Deodorisation & continuous
Deacidification separately as well as in combined form in
single or multiple tray and in single or double shell design.The
systems have been designed to handle all type of oils &
fats to produce highest quality cooking oils & fats
including palm oil and rice bran oil. .
SPEC
offeres capacities upto 200 TPD for Continuous Deacidification
and Deodorisation.
SPEC
is developing indeginous process for recovery of high value
products from distillates.
MAIN
FEATURES AND ADVANTAGES OF PHYSICAL REFINING
-
Simple operation
- Process
control is accurately monitored through instrumentation.
- Precise
control of all parameters i.e.temperature, flowrate,vacuum,residence
time
- Lowest
Energy cost due to most efficient heat recovery system
- Multi pass system on tube side as well as shell side
ensures long contact time thus achieving more than 80%
effeciency.
- Pre
stripping in bulk with mammoth pump
- Low
temperature & high temperature deaeration ensures
higher shelf life
- All
Heating and cooling under vacuum & live steam.
- Specially
designed on line oil seperator from fatty acid distillates
ensure lowest neutral oil losses.
- Multi
channel trays ensure live steam requirements between 0.8-1.5%
