Soy Oil Press Machine

The whole soya oil press machine contains three workshops: soybean pretreatment workshop, soybean oil extraction workshop and soybean oil refining workshop.

1. Craft flow for soybean pretreatment workshop

soybean → magnetic box → cleaning → softening → flaking → cooker

→ to extraction workshop

Main Equipments of soybean pretreatment workshop:

1).Soybean: The oil content in the soybean is about 20-45%.

2). Magnetic box: Clearing the iron impurity which might be in the soybean.

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

machine.

3). Cleaning: Removing the stone or solid impurities in the soybean, in case of they will infPeanut Oil Press Machine|Rapeseed Oil Press Machine|Sunflower Oil Press Machinece the oil yield rate and desolventizing of wet meal in the next process.

4). Softening: It is used to adjust the water in the soybean and it change the state of the cell in the soybean.

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

6). Cooker: The machine is used to adjust the water content in the soybean flaker.

2.Craft flow for soybean oil solvent extraction workshop

solvent

↓

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

↓

Wet meal → DTDC toaster → soybean cake

Main Equipments of soybean 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 soybean oil refining workshop

Crude soybean oil → degumming and deacidification→ decolorization →deodorization

→ refined soybean oil.

Main Process of soybean 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 soybeanoil. 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 soybean 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.
