SAPONIFICATION
6
Saponification process consist in dosing
pre-treated raw materials in exact
ratio for a proper reaction in order to
produce liquid soap. The choice of
process is given by the raw materials
available:
FATTY ACIDS or NEUTRAL FATS.
FATTY ACID
The soap produced for fatty acids is
pure as it normally doesn’t contain any
glycerine or impurities. This process is
also called neutralization.
NEUTRAL FATS
The soap produced for neutral fats
contains glycerin, in traces or in quantity.
Glycerin is an integral component
of neutral fats. FULL BOILED process
“washes” the soap in order to extract
glycerin. HALF BOILED process leaves
the glycerin inside the soap.
FATTY ACIDS
Fatty acids saponification can be done
continuous or batch.
BATCH
Batch type fatty acids neutralization is
simple and flexible. Raw materials,
fatty acids, soda, salt and water are
dosed in the Crutcher and mixed until
their complete reaction. Raw materials
can be dosed by means of flowmeters,
coverelevated tanks or load cells.
CONTINUOUS
The advantages of Soaptec continuous
fatty acids neutralization are: reduced
volumes, reaction under preassured
and possibility of production of concentrated
soap.
All raw materials, fatty acids, soda,
salt and water are dosed continuously
in the Turbo Mixer located before the
saponification reactor where the reaction
is completed under intense and
continuous mixing.
Raw materials can be dosed by massflow
meters or proportioning pumps.
NEUTRAL FATS
Neutral fats neutralization can be done
in continuous or in batch.
BATCH FULL BOILED
This process requires a classic saponification
kettle where the soap maker
controls the whole process from raw
materials dosing to the final neat soap
specs adjustment.
CONTINUOUS FULL BOILED
Raw materials, neutral fats, soda, salt
and water are dosed continuously into
the saponification reactor for a complete
reaction under high pressure and
temperature.
A passage through the cooler brings
the soap and line mixture to a graining
temperature.
Soap, subsequently separated in static
separator is countercurrently washed
inside washing column. Last traces of
lye are eliminated from the soap inside
centrifugal separator. Eventual excess
alkali are neutralized in the neutralization
section.
BATCH HALF BOILED
Batch type neutral fats neutralization is
simple and flexible. Raw materials,
fatty acids, soda, salt and water are
dosed in the Crutcher and mixed until
their complete reaction. Raw materials
can be dosed by means of flowmeters,
over-elevated tanks or load cells.
CONTINUOUS HALF BOILED
The advantages of Soaptec continuous
neutral fats neutralization are: reduced
volumes, reaction under preassured
and possibility of production of concentrated
soap.
All raw materials, neutral fats, soda,
salt and water are dosed continuously
in the Turbo Mixer located before the
saponification reactor where the reaction
is completed under intense and
continuous mixing.
Raw materials can be dosed by massflow
meters or proportioning pumps.
