Solution
The vegetable oil production line covers four major links: pretreatment, pressing/extraction, refining, and packaging. Equipment investment accounts for more than 60% of the total factory cost. In 2023, the global vegetable oil market will reach US$215 billion (Grand View Research data), of which rapeseed oil, soybean oil, and palm oil account for more than 70%, driving the production line to upgrade to automation and low energy consumption.

In the field of vegetable oil production, a complete and suitable set of vegetable oil production line equipment is the key to ensuring production efficiency and oil quality. Different daily processing volumes and different customer demands for oil products will affect the configuration of vegetable oil production line equipment.

Daily capacity 1 - 10 tons: basic pressing equipment configuration

When the daily production capacity of oilseeds is between 1 and 10 tons, a set of edible oil pressing equipment can meet the production needs. The single screw oil press, automatic temperature control oil press, hydraulic oil press and integrated oil press with automatic vacuum filtration and temperature control provided by QIE GROUP are all commonly used equipment in this stage.

The structure is simple and easy to operate, which is suitable for small processing scenarios. The automatic temperature control oil press can accurately control the temperature during the oil pressing process to ensure the pressing effect. The integrated oil press integrates multiple functions in one. It not only has an automatic vacuum filtration function, which can effectively remove impurities in the squeezed oil, but also has a temperature control function. It can adjust the temperature according to the characteristics of different oil seeds, thereby improving the pressing efficiency and oil quality.

If customers have higher requirements for finished vegetable oil, they can also install an oil pan. By adjusting the oil pan, the temperature, humidity and internal structure of the oilseeds can be changed, so that the oilseeds can reach the best state before pressing, further improving the pressing efficiency and oil quality.

Single screw oil press

Daily capacity 10 - 20 tons: pretreatment and pressing combined

When the daily production capacity of oilseeds is 10-20 tons, the vegetable oil production line needs to be equipped with edible oil pretreatment equipment and edible oil pre-pressing equipment.

Edible oil pretreatment equipment includes cleaning equipment, flaking machine and steam cooker. Cleaning equipment can effectively remove impurities in oilseeds, such as sand, gravel, iron filings, etc., to prevent impurities from causing wear on subsequent processing equipment and extend the service life of the equipment. Flaking mills can break oilseeds into uniform flakes, increase the surface area of ​​oilseeds, and improve pressing efficiency. Steamers can steam and fry the oilseeds after flaking, adjust the temperature and moisture of the oilseeds, and make them suitable for pressing.

The edible oil pre-pressing equipment can perform preliminary pressing on the oil seeds to extract a portion of the edible oil. Subsequently, the edible oil filtering equipment filters the pre-pressed oil to remove solid impurities. After that, the edible oil hydraulic press equipment is used for secondary pressing to extract more edible oil from the oil seeds and reduce oil loss. This pressing process uses only mechanical pressing to extract edible oil from oil seeds, which retains the natural aroma and nutrients of the oil to the greatest extent, meeting consumers' demand for high-quality vegetable oil.

Vegetable oil pretreatment process

Daily production capacity exceeds 20 tons: complete set of solvent extraction equipment

When the daily production capacity of oilseeds exceeds 20 tons, it is more efficient to use the extraction method to extract edible oil. At this time, the vegetable oil production line needs to include edible oil pretreatment equipment, edible oil pre-pressing equipment, edible oil solvent extraction equipment and edible oil refining equipment.

After being processed by edible oil pretreatment equipment and edible oil pre-pressing equipment, oilseeds can be used to obtain edible oil and oilseed cake. Crude oil contains a variety of impurities and needs to be further refined using edible oil refining equipment. Refining equipment removes phospholipids, free fatty acids, pigments and odor substances from crude oil through processes such as degumming, deacidification, decolorization and deodorization, thereby improving the quality and stability of the oil and making it meet edible standards.

The oilseed cake needs to be transported to the extraction workshop and extracted using edible oil solvent extraction equipment. The extraction equipment uses the oil solubility principle and solvents to extract the remaining edible oil from the cake. After extraction, the residual oil rate in the oil cake is less than 1%, which greatly improves the oil yield of oilseeds, allowing vegetable oil producers to squeeze out more oil, thereby increasing profitability and revenue.

Vegetable oil solvent extraction equipment

Therefore, the equipment used for vegetable oil processing in vegetable oil production will vary according to the daily processing volume and specific customer needs. At present, QIE GROUP has developed various vegetable oil processing equipment solutions for customers in many countries and has accumulated rich project implementation experience.
