The main function of Small Scale Edible Oil Refinery decoloring process is to remove oil pigment, residual soap grain and metal ions. Under negative pressure, bottom price canton fair QI'E brand shea nut oil extraction the mechanical mixing method combined with steam mixing will improve the decoloring effect. Shandong Leader Machinery Co.,ltd. The degummed oil firstly enters into the heater to be heated to the appropriate temperature (110°C), and then Small Scale Edible Oil Refinery goes to the bleaching earth mixing tank. bottom price canton fair QI'E brand shea nut oil extraction The bleaching earth is delivered from the low bleaching box to the temporary tank by wind. The bleaching earth is added by automatic metering and is interlockingly controlled with the oil. Small Scale Edible Oil Refinery The oil mixed with the bleaching earth overflows into the continuous decolorizer, which is stirred by non-powered steam.Shandong Leader Machinery Co.,ltd. The decolored oil enters into the two alternate leaf filters to be filtered.

| The brief introduction for shea nut oil extraction |
* Extraction process
The pre-pressed cake or flake, firstly enter into the sealed scraper blade to avoid
the solvent gas escaping because of the section without screw blade in the sealed auger.
Material seeds enter into the box-chained loop type extractor counter-currenting with
the solvent, the grease is extracted.
Miscella condnesity increase from 2% to more than 25%.
Miscella discharged from extractor and into miscella filter, then the leached meal
in the miscella tank enter into evaporation system through the first evaporation
feed pump and finally drop-in DTDC out from wet meal drag conveyor.
*Evaporation process
Using the secondary steam desolventized from DTC desolventizer and produced by
steam-jet pump to heat and evaporate micella in the first long-tube evaporator.
Export temperature reaches to 58-62°c and condensity reaches to more than 65%.
Then, micella enters into the second long-tube evaporator in which the temperature
is heated to 105-110°c by indirect steam and the condensity reaches to more than 95%.
Then miscella enters into stripper in which residual solvent in oil will be removed,
the export temperature reaches to about 105°c and the general volatile of the
extracted crude oil is less than 0.30%.
*Desolventizing process
Wet meals discharged from the bottom of extractor enter the top of DTDC and
land on the predesolventizing trayers where thery are heated by the indirect steam,
thus, some solvent in meal is evaporated and meal temperature is risen.
Predesolventized meals land on predesolventizing trayers where they use the second
steam in desolventizing trayers to predesolventize solvent from meal, then meals enter
desolventizing layers in which direct steam is injected.
Direct steam is sprayed into the meals through the bottom holes, and distill the
solvent from meal by using steam in order to remove all solvent.
Desolventized meals land on the following drying and cooling layer to dry and cool meals,
cooled meals land on meal scraper blade from automatic material controlling gate on the
bottom of cooling layer, and then they are entered into meal storehouse.
*Condensation recovery process
Extractor is equipped with a separate condenser, first and second evaporation share
one condenser. Low and high temperature of solvent gas both from first and second
evaporation enter into the condenser after its neutralization, which greatly reduces
the load of condenser and improves the efficiency of condensing.
Stripping and analyzing share one condenser, the non-condensable gases from extractor
and other condensers enter into the vent gas recovery system through the final condenser.
In the recycling system, the cold paraffin will absorb the solvent gas and the final
nonsolvent gas will be discharged through fire resistance valve.
Paraffin absorbed the solvent gas can be also called rich oil, after heating by oil-oil heat
exchanger and steam, the rich oil will enter into desorber for desorption,
and into condenser after changing solvent into gas,
the final cooled paraffin can be recycled.

| Advantages for shea nut oil extraction |
* Absorbing the world's leading core extraction technology, design and develop
a process which is efficient, economical and reliable. Adopting box-chained loop
type extractor can effectively achieve low residual oil, low solvent consumption
and low failure rate of equipment.
* Full automatic computer control system is adopted in extracting process,
adjust automatically and operate stably.
* Negative pressure technology is adopted in condensate system.
* Stainless steel heat exchange tubes and multistage baffling make the condenser
have a high heat transfer effciency, also the water consumption is low.
