This peanut rosted drum type machine is mainly used to roast various kernels, for example, peanuts, chestnuts, walnuts, almonds,beans, melon seeds and other granular material of the baking or drying. The machine with electric heating type, fuel oil type, gas type, or coal type as a heat source; Principle of adopting rotary drum, heat conduction, heat radiation and using coal as fuel; It has automatic temperature control device; Hot air as the drying medium, the heat enerLD works on roasted peanut, which is constantly propelled by propulsion device in roasting process.
When the oil leaves the screw press it contains water, sand and impurities. During a process of static de-sanding and decanting, most of the impurities in the oil are removed in a centrifugal oil purifier. The last traces of oil in the effluent are recovered in a centrifugal sludge separator.
Specifications1.Groundnut oil processing machine
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. LigLD weigLD, 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
(1). Refining pot: used to P-acid de-gumming, alkali refining de-acid and
(2).De-color pot: used to remove off pigments, bleaching oils and grease de-
(3).De-odor pot: used to remove off oils odor, foreign smells (stainless made)
Heat-transfer oil stove: supply each device production needing heat enerLD, temperature reach above 280 ÃÂÃÂÃÂÃÂ° 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:
(1).P-acid degumming operation:
Drawing the filtered or settled crude oil into the neutral pot, control oil te-
mperature 40 ÃÂÃÂÃÂÃÂ° 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 weigLD.Start
up neutral pot, make main shalf stirring at 60-70 r/min, finish de-gumming
in 30 min.
(2)alkali de-acid operation
After finish de-gumming process, at once add into lye carrying alkali refini-
ng de-acid, lye concentration 16 ÃÂÃÂÃÂÃÂ° Be ÃÂÃÂ¢ÃÂÃÂÃÂÃÂ², super alkali is 0.1-0.3% oil weigLD, after finish 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 ÃÂÃÂÃÂÃÂ° 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
Adjust the neutral pot oil temp to about 85 ÃÂÃÂÃÂÃÂ° C, add into hot water whose
temp higher oil temp 10-15ÃÂÃÂÃÂÃÂ° C, the water use amount each time is 10-15% oil weigLD.
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.
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 ÃÂÃÂÃÂÃÂ° C, carrying vacuum dry hydrate, about 30 min, no frog in the pot, indicate that the dehydrate finished.
After dehydrate, inhale 3-5% oil weigLD 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 ÃÂÃÂÃÂÃÂ° 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
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 ÃÂÃÂÃÂÃÂ° C - 260 ÃÂÃÂÃÂÃÂ° C, use the direct steam under 0.1 -0.3Mpa
to distillate 3-4 hours.
Shut off steam, shut off heat source, when the oil temp cooling to below
80 ÃÂÃÂÃÂÃÂ° C, shut off vacuum, release 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 salad oil refining process is same to the high-cooking 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.
