 Product Description

Peanut Screw Oil Press

The whole peanut screw oil press 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 → crushing and flaking roll → plate dryer → to extraction workshop

Main Equipments:

1. Peanut: Peanut is a tranditional oilseed. It can be made to normal peanut oil and flavor peanut oil. It is popular in many countries.

2. Magnetic box: Clearing the iron impurity which might be in the peanut. The iron impurity will

be harmful to the following machines, so we need take the iron impurities out.

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 peanut.

4. Crushing and Flaking roll: The size of peanut is big, so it's devided into small piece. Then it's made to thin cake for pressing.

5. Plate dryer: Before entering the solvent extractor, the water content must be about 10%, so the dryer is used to adjust the water content.

↓

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

Wet meal → DTDC toaster → cake

Main Equipments:

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

2. Roary extractor: spray and soak the 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 peanut oil refining workshop

Crude peanut oil → degumming and deacidification→ decolorization →deodorization → refined peanut 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 edible 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 edible 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 edible oil.
