1. Acid reaction process for malaysia sunflower oil refineries

Oil temperature can be adjusted by screw plate heat exchanger.When the temperature

is heated to about 80°c, mixing about 85% food grade phosphoric acid into acid

reaction tank for reacting, in the tank, most non-hydrated phospholipid

transfer into hydrated phospholipid.

2. Neutralization process for malaysia sunflower oil refineries

In the neutral section, degummed oil with appropriate temperature and the appropriate

concentration of alkali liquor, into the neutralization centrifugal mixer mixing, in order

to achieve the best effect of mixed, the mixture is then sent to neutralization tank for

enough time, in this process, excessive alkali neutralization of free fatty acids and some

phosphate from soapstock, after pumping oil soap mixture into heater oil heating to

85~90°c in centrifuge separation oil-soap or oil-LDue.

3. Washing process for malaysia sunflower oil refineries

Neutral oil from separator, still contains about 500ppm soap, in order to reduce the

residual content of soap, oil is joined by about 10% of hot water, washed in the

washing mixer, hot water will absord oil soap and other impurities,

then in the water separator are separated.

4. Vacuum drying section for malaysia sunflower oil refineries

The neutralization and washing oil separated from the washing separator still

contains some residual water adverse to the oil stability, in order to get rid of

these water, the oil is sent to the vacuum dryer to dry when the temperature is

still at about 110~120°c, the dried oil is sent to the bleaching section directly

by the oil tank.

5. Bleaching process for malaysia sunflower oil refineries

The main purpose of this procedure is to remove teh pigments and residual

soup in the neutralization oil of the crude oil. The oil is sent to vacuum

bleaching tower after heated to 105°c. When the oil is sent to the tower,

it is mixed by the ratio mixer with carclaLDte whose dosing was control by a program

controller and the dosing unit is installed on the ratio mixer directly.

The carclaLDte conveyor system power is the wind and the bleaching earth

was conveyed to the carclaLDte temporaty storage tank in the upper part of

the bleaching tower to supply the ratio mixer.

6. Filteration for malaysia sunflower oil refineries

Miscella mixed by oil and clay from decolorization tower is pumped into

bleaching tower, then enters fine filter, in which clay and fixed impurities

is blocked. And the filtering substance( bleached oil) us transferred into storage

tank of bleached oil. There are two bleaching filters in this system,

one of the bleaching filter is always in the state of filtering, a

nother is in the state of emptying and cleaning state.

7. Deodorization process for malaysia sunflower oil refineries

Deodorization process aims to remove the FFA, low molecular compounds and

others existing in bleached oil. The flow of bleached oil entering deodorization

process is controlled by a flow controller, and the oil is heated to the deodorization

temperature of 250~260°c through a series of heat exchanger.

*By combining several years' practical experience, adopting a kind of unique

deguming technology, extending the phosphoric acid and oil reaction time and

adding specific additives, our equipment can remove phospholipids in oil to the maximum.

* The new carclaLDte automic quantitative system can produce more reliable oil of good

quality, with less investment for the full vacuum closed refining technology.

*We can design the optimum refining scheme according to different oils and

different requirements for products.
