Screw oil press for canola

Shandong Leader Machinery Co.,ltd. the crude oil is output by the oil feed pump from the oil tank, and cottonseed oil manufacturing process next enters the crude oil heat exchanger to recover part of heat cottonseed oil manufacturing process after metering and then is heated to the required temperature by the heater. After that,cottonseed oil manufacturing process is mixed with the metered phosphoric acid or citric acid from phosphate tank in the gas mixture (M401), and Screw oil press for canola then enters the conditioning tank (R401) to make the non-hydratable phospholipids in oil change into the hydratable phospholipids. Add the alkali for neutralization, and Screw oil press for canola the alkali quantity and alkali solution concentration depend on the quality of the crude oil. Through the heater, the neutralized oil is heated to the temperature (90°C) suitable for centrifugal separation to remove the phospholipids, FFA and other impurities in the crude oil. Then the oil goes to the washing process. cottonseed oil manufacturing process there is still moisture in the oil from the wash separator, and the moisture will affect the stability of the oil. So the oil at 90°C should be sent to vacuum drier to remove the moisture

Main Economic and Technical Parameters of Rotocel Extractor

Method of Canola oil extraction process

1) The material will be have a pretreatment process , we need to clean the canola , crush , cook , flaking , press the canola . the oil residue in the cake is about 7-8 % .this method is suitable for small capacity ,not large .

2) The method is pre -press and solvent extraction method .It means we press the canola first , then the oil residue left is about 12- 13% in the cake . Then we send the cake to extractor to leah the oil from the cake ,which make surethe oil residue is about 1 % . This method is for larger capacity ,and the invest is a little big .

Introduction of oil extraction

1) Function: Leaching system is an oil extraction through soaking or spraying pre-pressed cake by a certain organic solvent. The principle of this part is the different solubility of solvent.

2) Use range: Solvent extraction fits for pre-press extraction of high-oil-content materials and direct once time extraction of low-oil-content materials.

(3) Main parts: The extraction series includes rotary extractor, toaster, 1st evaporator, 2nd evaporator, stripping tower, condenser, etc.

Main parts of canola oil extraction machine

Solvent pumps: continuously spray solvent to the rotary-type 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: usd to separate the solvent from the wet meal.

(4). Miscella tank 1st: pump the miscella (oil with solvent) in to the miscella 1st , and then add 10% saline water to it.

The phospholipid and impurities in the miscella will react with the saline wter, 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.

Refinery Process

Crude canola oil - degumming ( remove phosphilid ) - decolorization ( remove pigment ) - deodorization ( remove odour )

welcome to order from us

Shandong Leader Machinery Co.,ltd. there is still about 500ppm soap in the neutralized oil from the separator. To remove the remaining soap, cottonseed oil manufacturing process add into the oil about 5~8% hot water, with water temperature 3~5 °C higher than the oil generally. Screw oil press for canola To achieve more stable washing effect, add phosphoric acid or citric acid when washing. The re-mixed oil and water in the mixer is heated to 90-95°C by the heater, and Screw oil press for canola then enters the wash separator to separate the remaining soap and most water. The water with soap and oil enters into oil separator to separate out oil in the water. Further catch the oil outside, cottonseed oil manufacturing process and the waste water is discharged to the sewage treatment station.and then Shandong Leader Machinery Co.,ltd. the dehydrated oil goes to the decoloring process. Finally, pump out the dry oil by canned pump.
