2013 new technology groundnut oil pressing equipment

2013 new technology groundnut oil pressing equipment is mainly composed of 7 major parts of screw axis, press cage, feed mechanism, cake yielding mechanism. transmission system, electric control part and vacuum filter part. All the parts are assembled on the frame and screwed as a whole.

Advantage of 2013 new technology groundnut oil pressing equipment:
Service is our aim,Shandong Leader Machinery Co.,Ltd. are now a leading company in edible oil production plant field.Shandong Leader Machinery Co.,Ltd. supply various oil production plant and connected equipments. 300 people service team, escort for your project.
(1) High oil yield , obvious economic benefit .
(2) Lower residual oil rate in the dry meal .
(3) Improving the quality of the meal .
(4) Low processing cost , high productivity.
(5) Saving energy,saving labor.

Pressing process of 2013 new technology groundnut oil pressing equipment:
a. Pre-press: Press the flakes to leave about 16%-18% in the cake. The cake will go to extraction process.
b. Second oil press: Press the cake till the oil residue is about 5%.
C.Oil extraction effect is good, high oil extraction rate.

Specifications

2013 new technology groundnut oil pressing equipment.

The whole peanut oil extraction machine contains three workshops: peanut pretreat-

ment and prepressing workshop, peanut oil extraction workshop and peanut oil

refining workshop.

1. Craft flow for groundnut oil pretreatment and prepressing workshop

Groundnut→ magnetic box → cleaning → crusher → flaking roll → cooker → oil prepre-ssing → to extraction workshop

Main Parts:

1. Peanut: It’s a kind of main oil seeds. It’s used to make peanut oil around the world.

The oil content in peanut seed is about 48-55%.

2. Magnetic box: Clearing the iron impurity which might be in the peanut. Because the iron impurity will be harmful to the screw of extrusion machine.

3. Cleaning: This parts have different size cleaning sieves to clean the different impur-ities. After going through this

part, most of the impurities are moved from peanut.

4. Crusher: Because of the big size of peanut, it need to be crushed to small pieces. The

crusher will help to get more peanut oil from the seeds.

5. Cooker: This machine can adjust the water content of the peanut. It’s also good for

the prepressing and oil extra-ction section.

6. Prepressing: The press machine is used to take parts of the oil in the peanut first, because the high oil content in the

peanut. Then the crude oil will sent to peanut oil refinery workshop, and the cake will

sent to peanut oil extraction workshop.

2.Craft flow for groundnut oil extraction workshop

solvent

↓

extractor → mixed oil → 1st and 2nd evaporation → stripping tower → crude peanut oil

Wet meal → DTDC toaster → peanut meal

Main Parts:

1. Solvent pumps: continuously spray solvent to the rotary-typr extractor.

2. Roary extractor: spray and soak the prepressed cake with solvent so that oil fats can

be dissolved in solvent

(form miscella).

3. DTDC: used to separate the solvent from the wet meal.

4. Miscella tank 1st: pump the miscella ( oil with solvent) into the miscella 1st, then

add 10% saline water to it. The phospholipid and impurities in the miscella will react

with the saline water, at last the reactant precipitate, reaching the goal of purifying.

5. Miscella tank 2nd: the purified miscella will be pumped into it.

6. Miscella stripping: it will remove the remaining solvent in miscella. And the solvent

will be discharged to condenser for recycling.

7. Condensers: used to cooling the solvent gas separated from the wet meal and mis-cella for recycling.

3. Craft flow for groundnut oil refining workshop

Crude peanut oil → degumming and deacidification→ decolorization →deodorization

→ refined peanut oil.

Main Processes:

1. Degumming and deacidification: The gumming is moved by phosphoric acid and

hot water. There are two ways to move the acid in the peanut oil. One is chemical

way, the other one is physical way.The chemical way is using NaOH to react with acid.

This way is suitable for the capacity of 5-30T per day. The physical way is using

steam and centrifugal to move the acid. It is for capacity from 30-600TPD.

2. Decolorization: This step is used to adjust the color of the oil.

3. Deodorization: The

function of this step is to move the special smell in the oil. This is an important stand-ard for refined peanut oil.
