The qualified decolored oil Screw Hydraulic Oil Press machine enters into the spiral plate heat exchanger to recover most of the heat, and Cheap price professional Industrial rapeseed oil refined with CE approved next goes to high pressure steam heat exchanger to be heated to the process temperature (240-260°C) and then enters the deodorization tower. Shandong Leader Machinery Co.,ltd. The upper layer of combined deodorization tower is the packing structure which Screw Hydraulic Oil Press machine is mainly used to remove the odor producing components such as free fatty acid (FFA); Shandong Leader Machinery Co.,ltd. the bottom layer is the plate tower which is mainly for achieving the hot decoloring effect and reducing the peroxide value of the oil to zero. Screw Hydraulic Oil Press machine Oil from the deodorization tower enters into the heat exchanger to recover most of the heat and makes further heat exchange with crude oil, and then is cooled to 80-85°C through the cooler.
Cheap price professional Industrial rapeseed oil refined with CE approved
1.Characteristics of rapeseed oil refined
This units belongs to intermittent refining oil equipment, has all functions
of large, small scale intermittent refining equipment, and better than them.
This equipment can produce high-cooking oil or salad oil.
This units complete set combined, self-prepare heat source, gas source, electrics control. Light weight, save electricity , convenient use, this machine do not need special basis,
either indoor or outdoor is OK, just need to make up power source, water, prepare coal, alkali, P-acid, active clay, edible salt and other consume materials.
2. Units devices of rapeseed oil refined
(1). Refining pot: used to P-acid de-gumming, alkali refining de-acid and
water rinsing.
(2).De-color pot: used to remove off pigments, bleaching oils and grease de-
hydrate.
(3).De-odor pot: used to remove off oils odor, foreign smells (stainless made)
Heat-transfer oil stove: supply each device production needing heat energy, temperature reach above 280 ° C.
(4).Steam generator: produce the needing steam for de-odoring and distillation.
(5).Vacuum pump: supply needing vacuum for dehydrate, de-color, de-odor. Vacuum degree can reach above 755mmHg.
(6).Press filter: filter clay, filter out clear oil.
(7).Air compressor: blow dry bleached clay, blow empty the leftover oil in
the press filter.
3.Main refining process of rapeseed oil refined
(1).P-acid degumming operation of rapeseed oil refined
Drawing the filtered or settled crude oil into the neutral pot, control oil te-
mperature 40 ° C, liquid level cover the neutral pot volume about 80 %.Add
into the neutral pot P-acid with 85% concentration, 0.1-0.2% oil weight.Start
up neutral pot, make main shalf stirring at 60-70 r/min, finish de-gumming
in 30 min.
(2)alkali de-acid operation of rapeseed oil refined
After finish de-gumming process, at once add into lye carrying alkali refini-
ng de-acid, lye concentration 16 ° Be ′, super alkali is 0.1-0.3% oil weight, afterfinish adding, continuous stirring 30min, when soap particles accumulated condensing, should reduce stirring speed, 30r/min avoid emulsion.
After adding alkali, gradually rising temp to the end temp 65 ° C, see to th-
at the rising temp speed should control at 1 degree per minute, not too fast.
Shut off neutral pot drive part, the oil settled in the pot 6-8 hours, make oil separate from soap.
(3)water rinse operation of rapeseed oil refined
Adjust the neutral pot oil temp to about 85 ° C, add into hot water whose
temp higher oil temp 10-15° C, the water use amount each time is 10-15% oil weight.
Start neutral pot drive part, make the main shalf stirring washing at 30r/m-
in, make the oil and water fully contact, stirring time 5-10 min.
If oil/soap separate not ideal, the oil contains relative high left soap, the fir-
st time washing, better to use thin salt water evenly spray into oil.
(4).De-watering of rapeseed oil refined
Start vacuum machine, open the vacuum valve on the de-color pot, make
the pot inside vacuum above 750mmHg , inhale the clear oil after water rin-
se into the de-color pot.
Start up de-color pot main axis, stirring at 30r/min, and make the pot inside oil temp reach 90 - 95 ° C, carrying vacuum dry hydrate, about 30 min, no frog in the pot, indicate that the dehydrate finished.
(5).de-coloring of rapeseed oil refined
After dehydrate, inhale 3-5% oil weight active clay into the de-color pot to
carry absorb de-coloring.
De-color pot main axis stirring speed 60r/min, time 20 min, vacuum degr-
ee 750mmHg, is the whole absorb de-color craft process requirement.
Shut off vacuum valve, open vacuum break valve, stirring non-stop, reduce
the oil temp down to 70 ° C, the de-color finished.
Continuous stirring, open oil outlet valve, press the de-color oil into the pre-
ss filter, filter away waste clay, the last use air compressor blow clean and dry
(6).De-odor operation of rapeseed oil refined
Open the vacuum valve, make the pot inside vacuum degree gradually reach above 750mmHg.
Inhale the de-color oil after filter into the de-odor pot, see to that oil amount should cover the pot volume 60%.Control oil temp at 240 ° C - 260 ° C,
use thedirect steam under 0.1 -0.3Mpa to distillate 3-4 hours.Shut off steam, shut off
heat source, when the oil temp cooling to below80 ° C, shut off vacuum, re-
lease de-odor oil , the de-odor process has finished.
Until now, the product oil after de-odor is high cooking oil, there are some
factories carrying again one time fine filtering after de-odor to increase the o-il qulity.
The sunflower oil refining process is same to the high-sunflower oil refining process, just has a little higher requirements in each section, for example, during alkali refining, the super amount alkali a little much, when de-coloring, the bleaching agent much, de-odor time properly longer, the temp relatively higher, add one fine filtering section.
