Soybean oil Extraction with Oil Pressing Machine

Soybean oil extraction

Soybean oil is one of the major vegetable oils in the world, occupying a significant share in the global edible oil market, and the global production of soybean oil is usually more than tens of millions of tons. China, the United States, Brazil and other major producers of soybean oil.

Since the oil content of soybean is in the range of 15%-26% and the oil yield is in the range of 12%-18%, the oil pressing method has been an important and effective method in the production of soybean oil.

Generally, the gross oil with more impurities is obtained after treatment with various methods such as pressing method and leaching method, and then the edible refined oil is obtained after refining.

To ensure your soybean oil production is at its optimal level, Zhengzhou Fude Machinery’s oil extraction solution covers every key step from pretreatment and pressing to screw pressing operations.

Soybean Steaming & Frying in Oil Extrac​ting Method

In addition to the soybean pretreatment stage of soybean cleaning, crushing and softening, embryo making, before the extraction of soybean oil, the soybean embryo steaming directly affects the subsequent process and the quality of the oil, and aimed at destroying the cell structure of soybeans, help to improve the extracting rate of oil.

In the process of steaming & frying into the steaming pot, the reasonable control of the steaming and frying parameters is the key to ensure the maximization of the effect of the oil extraction process. The following is the key parameters of the optimization proposals:

Rational Control of Soybean Streaming Parameters

Note on cold pressing of soybeans：

Can be whole seed pressing, so that the whole seed pressing to strictly control the moisture, generally control 8-10% , and pay attention to the heating of the press to be the body temperature rose to about 80 ℃ before pressing.

How to Select Su​itable Soybean Oil Pressing Mill for Business?

• Matching equipment selection: the basis for quality pressed soybean oil production

Different production and processes have different requirements for soybean extraction equipment. For example, some equipment may be better suited to specific pressing temperatures and pressures. Ensure that the equipment you select meets the requirements of your production process in order to obtain high quality soybean oil.

• Matching production size: increasing productivity

Different sizes of soybean oil pressing equipment are suitable for different production needs. Fully understand the scale of production and market demand to determine the capacity of the required equipment. Selecting equipment that matches the production scale helps to improve efficiency.

The above is detailed information about the soybean oil pressing method. If you have any questions about the prices, manufacturers, models, or pictures of vegetable oil production plants, please feel free to contact us at any time!

Efficient Extraction: Soybean Oil with Screw Press Machine

Decoding the Working Principle of Screw Oil Press

Screw oil press is used to extract oil from soybeans and other oilseeds by mechanical pressing. Its main parts include feeding port, pressing screw, pressing screw barrel, material box, oil residue port and oil tank.

• Feeding stage: pre-processed soybeans are put into the feed opening of the screw presser.
• Pressing stage: Soybeans are pushed into the press screw barrel by the screw, and with the rotation of the screw, soybean oil is squeezed inside the barrel. Due to the spiral shape of the screw, the oil is squeezed out during the gradual pressurization process and discharged through the slag outlet.
• Separation and filtration: The extracted crude oil passes through the filter and other separation equipment to separate the oil and residue, and finally flows into the oil tank.

Cleaning and Maintenance of Screw Oil Press

• In order to ensure the efficient operation and prolong the service life of the screw oil press, regular maintenance is required. 

Regular cleaning: Clean all parts of the screw press, especially the oil residue opening and the feed box, to prevent the soybean residue from accumulating and affecting the production efficiency.

Check the lubrication system: Ensure that the lubrication system of the screw oil press machine operates normally, add lubricant in time to ensure the smoothness of the screw operation.

Check the screw wear: Check the screw wear regularly, and if necessary, replace the screws with serious wear in time to maintain the pressing effect.

Clean the filter screen: Clean the filter screen regularly to prevent clogging and ensure the quality of oil and grease extracted.
