2013 new technology groundnut oil pressing equipment

The production capacity of a 2013 new technology groundnut oil pressing equipment is between 1.5 and 10 kg of solid per m2 of filtering surface. For every filter press model, the chamber volume and the filtering surface depend on the number of Cooking oil making machine of complete set certificated by CE ISO BV plates.In practical terms pressing times are less then four hours. Filtration time depends on:cake thickness,sludge concentration,specific resistance,compressibility coefficient.One of the advantages of the Shandong Leader Machinery Co.,ltd. is that it can accept sludge with average filterability. 2013 new technology groundnut oil pressing equipment is always advantageous to optimally thicken sludge before filter press operations.When the Cooking oil making machine of complete set certificated by CE ISO BV has stopped, the filtrate circuits and central duct, which is still filled with liquid sludge, are purged by compressed air.Shandong Leader Machinery Co.,ltd. Washing of clothes should be carried out every 15-30 processing oprations. For mid- or large units this take place on press using water sprayers at very high pressure (80-100 bar).

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.

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.

2013 new technology groundnut oil pressing equipment.

After finish degumming process about 2013 new technology groundnut oil pressing equipment, at once add into lye carrying alkali refining deacid, lye concentration 16 ° Be ′, super alkali is 0.1to0.3% oil weight, 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 ° C, see to that the rising temp speed should control at 1 degree per minute, not too fast. Shut off neutral pot drive part, theoil settled in the pot 6-8 hours, make oilseparate from soap.
