bran extrusion flow chart:
Rice bran→ Magnetic separation→ Cleaning →Extrusion Puffing
→Counter-current drying→ To extraction plant
2. Main
process description:
Cleaning process:
Adopt the magnetic separator
to remove iron
miscellaneous, and use
rice bran and fine broken rice separation sieve to remove broken rice,fine broken rice etc.
Extrusion process:
Adopting the bulking machine can
both improve the yield
of rice bran oil and
reduce the
consumption. The extrusion puffing, on the one hand,
can
make solution lipase
in the rice bran
passivated under high
temperature and high pressure
condition,then prevent the rice
bran oil rancidity;
On the other hand,
the extrusion puffing can make rice bran
be porous mateial grain, and increases the
materials bulk density, then
improve the
permeability and leaching rate
which solvent
reacts to
the material.
Drying process:
The puffed
rice bran contains about
12%
water, and
the best moisture for leaching process
is 7-9%, therefore,
there
must be effective
drying means to achieve the
best leaching moisture.
Adopting flat dryer can make water and
temperature meet with
follow-up process requirements, and improve the
oil
yield, as well as
oil quality.
3.Process feature:
a) Different combinations of process
can process various oil plants in one workshop.
b)Use special intensified
pretreatment technology for aroma peanut oil to make it more aroma.
c) Adopt
advanced and reliable shelling technology to meet higher requirements for
protein content in meal.
d) Extrusion
treatment is used for raw materials with hard extraction, large-sized powder,
and large capacity, which can reduce residual oil and solvent consumption, and
increase the capacity by 50-80%.
e) The new technology of shelling and
low-temperature treatment can ensure high protein and least denaturation.

Solvent
recovery
a) Adopt stainless steel fixed grid
plate and increase the horizontal grid plates, which can prevent the strong
miscella from flowing back to the blanking case, so as to ensure good extraction
effect;
b) The rotocel extractor is driven
by rack, with unique rotor of balanced design, low rotating speed, low power,
smooth operation, no noise and quite low maintenance cost;
c) The feeding system can adjust the
rotating speed of airlock and main engine according to the feeding quantity and
maintain a certain material level, which is beneficial to the micro negative
pressure inside the extractor and reduce the solvent leakage.
d) The advanced miscella circulation
process is designed to reduce the fresh solvent inputs, reduce the residual oil
in meal, improve the miscella concentration and save energy by reducing the
evaporation capacity.
e) The high material layer of the
extractor helps to form immersion extraction, reduce the meal quality in
miscella, improve the quality of crude oil and reduce the evaporation system
scaling.
f) Specially suitable for the
extraction of various pre-pressed meals.
Main Economic and Technical
Parameters:
Wet Meal Desolventizing Process
Desolventizer toaster advantages:
a) Passivate and damage the
anti-nutritional components such as the urea enzyme and trypsin in the meal, and
improve meal value in use.
b) Control the protein denaturation
degree in the meal , and improve the NSI index effectively.
c) It can better regulate the color,
flavor and taste of the meal.
d) It can better reduce residual
solvent in the meal and regulate the meal moisture, so as to guarantee the
minimum solvent consumption and safe use of the meal.
Negative
pressure evaporation process
The liquid from the extractor is the miscella containing grease and oil, which
can be separated out according their different vaporization temperatures. Our
company mainly uses vacuum evaporation technology, and it can reduce solvent
leakage and consumption. The separated solvent vapour is cooled and recycled
back to the extractor for reuse, which can improve the solvent efficiency.
Vacuum
Evaporation Advantages:
a) Vacuum evaporation features high efficiency, thorough de-solvation and low
solvent consumption in crude oil.
b) Use the second steam of desolventizer toaster and remaining steam from steam
jet pump as the heat source of the first steam, which can save energy, reduce
the condenser configuration area and save investment.
c) Due to the low temperature of the steam, the crude oil features light color,
good quality and low residual solvent.
Solvent condensation & recovery process:
Solvent condensation system combines
with evaporation system closely, and evaporative condenser and steam stripping
condenser all work under negative pressure. Non-condensable gas enters the
energy saver from the shell of the first evaporator. In energy saver,
non-condensable gas exchanges heat with condensate from the evaporative
condenser. Finally, the condensate temperature discharged from energy saver is
increased, and the solvent separated from water goes to solvent holding tank.
The high temperature makes it unnecessary to be reheated for the recycling, so
as to save energy.
Non-condensable gas from energy
saver enters desolventizing condenser, in which a great deal of gas is
condensed, and the tail gas is discharged into the final condenser. The solvent
gas from the extractor enters extraction condenser, and the non-condensable tail
gas enters the final condenser. For the free gas in final condenser, diversion
box, holding tank, underground solvent library and miscella tank, cool them with
low-temperature cold water to recycle most of solvent gas. The tail gas with
little solvent goes to paraffin recovery process.

Oil
Refining Plant Introduction
Brief introduction for the equipment:
Refining pot: also named Dephosphorization and
deacidification tank, under 60-70℃, it occurs acid-base
neutralization reaction with sodium hydroxide. After stirring by reduction
box,it can decrease the acid value in oil and separate the impurity,
phospholipid which will enter into soap stock. The oil can be refined further.
Bleaching pot (decoloring pot): Also named bleaching and dewatering
pot, it removes water from oil by vacuum. The bleaching earth is breathed into
bleaching pot, after stirring,filtrated by filter and change the color of the
oil.
Vertical blade filter machine: Equipped with vertical leaf filter to
remove used bentonite from the oil, operating conveniently and continuously, low
laboring tense, keeps environment well, keeps oil residence in deposable
bleaching earth in low level.
Deodorization pot:It uses
USU 304 stainless steel plate, under the vacuum condition of vacuum and high
temperature (220-240℃), The deodorization
system can remove fatty acid and other
rare delicacy high efficiently .make Meanwhile, the pot has the advantage
of lowering steam consuming and avoid of the hydrolyzation of oil;
