NEUTRAL FATS

Neutral fats neutralization can be done in continuous or in batch.

BATCH FULL BOILED

This process requires a classic saponi-fication 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 com-plete 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 neutraliza-tion 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 con-

centrated soap. All raw materials, neutral fats, soda,

salt and water are dosed continuously

in the Turbo Mixer located before the saponification reactor where the reac-

tion is completed under intense and continuous mixing.

Raw materials can be dosed by mass-flow meters or proportioning pumps.

Saponification process consist in dos-

ing 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 quan-

tity. 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 con-centrated soap.

All raw materials, fatty acids, soda,

salt and water are dosed continuously in the Turbo Mixer located before the

saponification reactor where the reac-tion is completed under intense and

continuous mixing. Raw materials can be dosed by mass-

flow meters or proportioning pumps.
