| The Process for refined rice bran oil |
1. Acid reaction process for refined rice bran oil
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 refined rice bran oil
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 refined rice bran oil
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 refined rice bran oil
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 refined rice bran oil
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 refined rice bran oil
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 refined rice bran oil
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.
| The Advantages for refined rice bran oil |
*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.
