Hazelnut Oil Almond Oil Pressing Machine

Specifications

Almond Oil Pressing Machine

1.Characteristics:

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:

(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:

(1).P-acid degumming operation

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

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

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

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

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

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 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.

Note: We have the different oil mill factory for the visit and supply for the turn-key

project now and then.
