| Main Section Introduction of Peanut oil refining plant: |
(1) Refining section: used to P-acid de-gumming, alkali refining de-acid and water rinsing.
(2) Decoloring section: used to remove off pigments, bleaching oils and grease dehydrate.
(3) Deodorizing section: to remove off the odor components in oil.
(4) Fractionation section: used to remove off the wax in the oil, in order to get the high quality oil.
(5) Heat-transfer oil stove: supply each device production needing heat energy, temperature reach
above 280°C.
(6) Steam generator: produce the needing steam for de-odoring and distillation.
(7) Vacuum pump: supply needing vacuum for dehydrate, de-color, deodor. Vacuum degree can
reach above 755mm Hg.
(8) Press filter: filter clay, filter out clear oil.
(9) Air compressor: blow dry bleached clay, blow empty the leftover oil in the press filter.
| Process specification of Peanut oil refining plant: |
1.The degummed oil firstly enters into the heater to be heated to the appropriate temperature (110°C),
and then goes to the bleaching earth mixing tank.
2.The bleaching earth is delivered from the low bleaching box to the temporary tank by wind.
3.The bleaching earth is added by automatic metering and is interlockingly controlled with the oil.
4.The main function of decoloring process is to remove oil pigment, residual soap grain and metal
irons.
5.Under negative pressure, the mechanical mixing method combined with steam mixing will improve
the decoloring effect.
6.The oil mixed with the bleaching earth overflows into the continuous decolorizer, which is stirred
by non-powered steam.
7.The decolored oil enters into the two alternate leaf filters to be filtered.
8.Then the filtered oil enters the decolored oil storage tank through the security filter.
9.The decolored oil storage tank is designed as the vacuum tank with the nozzle inside, so as to
prevent the decolored oil contacting with the air and influencing its peroxide value and color
reversion.
