20-2000T groundnut oil extractor machine with CE and ISO

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.

Groundnut Oil Extractor Machine

The whole groundnut oil extractor machine contains three workshops: groundnut pretreatment and prepressing workshop, groundnut oil extraction workshop and groundnut oil refining workshop.

1. Craft flow for groundnut oil pretreatment and prepressing workshop

groundnut → magnetic box → cleaning → crusher → flaking roll → cooker → oil prepressing → to extraction workshop

Main Equipments:

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

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

2. Magnetic box: Clearing the iron impurity which migLD be in the groundnut. Since in the process of puffing, the iron impurity will be harmful to the screw of extrusion machine, affect the puffing effect.

3. Cleaning: This parts have different size cleaning sieves to clean the different impurities. After going through this part, most of the impurities are moved from groundnut.

4. Crusher: Because of the big size of groundnut, it need to be crushed to small pieces. The crusher will help to get more groundnut oil from the seeds.

5. Cooker: This machine can adjust the water content of the groundnut. It’s also good for the prepressing and oil extraction section.

6. Prepressing: The press machine is used to take parts of the oil in the groundnut first, because the high oil content in the groundnut. Then the crude oil will sent to groundnut oil refinery workshop, and the cake will sent to groundnut oil extraction workshop.

↓

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

Wet meal → DTDC toaster → groundnut cake

Main Equipments:

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

2. Roary extractor: spray and soak the pre-pressed cake with solvent so that oil fats can be dissolved in solvent (form miscella). After processing, you can get wet meal and miscella (mixed oil).

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 miscella for recycling.

3. Craft flow for groundnut oil refining workshop

Crude groundnut oil → degumming and deacidification→ decolorization →deodorization → refined groundnut oil.

Main Process:

1. Degumming and deacidification: The gumming is moved by phosphoric acid and hot water. There are two ways to move the acid in the groundnut 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. This way is used for capacity from 30-2000T per day.

2. Decolorization: This step is used to adjust the color of the oil. You can control the color of the groundnut oil according to the requirement of your market.

3. Deodorization: The function of this step is to move the special smell in the oil. This is an important standard for refined groundnut oil. Because of the good smell of groundnut oil, you can choose this step according to your market.
