Peanut Oil Extraction Machine

 

The whole peanut oil extraction machine contains three workshops: peanut pretreatment workshop, peanut oil extraction workshop and peanut oil refining workshop.

 

1. Craft flow for peanut pretreatment workshop

peanut → magnetic box  cleaning → husking → separator → flaking → cooker

→ to extraction workshop

 

Main Equipments of peanut pretreatment workshop: 

 

1).Peanut: The peanut is also called groundnut. The oil content in the peanut kernel is about 44-55%.

 

2). Magnetic boxClearing the iron impurity which might be in the peanut. 

Since in the process of puffing, the iron impurity will be harmful to the screw of extrusion 

machine. 

 

3). CleaningRemoving the stone or solid impurities in the peanut, in case of they will influence the oil yield rate and desolventizing of wet meal in the next process. 

 

4). Husking: If your material is peanut with shell, you must move the shell first.

 

5). Separator: This machine can separate the shell and the peanut kernel. The shell can be used as fuel and the peanut kernel can be made to peanut oil.

 

6). Flaking roller: The peanut kernel is made to small piece. This can improve the oil yield rate of the peanut.

7). Cooker: The machine is used to adjust the water content in the peanut flaker.

Main Equipments of peanut oil solvent extraction workshop:

 

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 toaster: 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 peanut oil refining workshop

 

Crude peanut oil → degumming and deacidification→ decolorization deodorization

refined peanut oil.

 

Main Process of peanut oil refining workshop:

 

1). Degumming and deacidification: The gumming is moved by phosphoric acid and hot water. There are two ways to move the acid in the rice bran 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 peanut 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 oil.
