What is the production process of cold pressed sunflower oil? What machine is needed?

Usually, we use physical pressing to extract cold-pressed oil from sunflower seeds, which is mainly divided into three stages: pretreatment section, pressing section, and filtering section. Next, I will introduce the production process and machine of cold pressed sunflower oil to you.

Cold pressing of oilseeds is an oil production process that meets the needs of "green" consumers. Cold pressing is a completely physical and mechanical method of oil production, so it avoids the contact between edible oil and organic solvents, acids, alkalis, active white clay and high temperatures that are the only common methods used today, and the resulting edible oil only needs to be filtered or dried to meet consumption requirements. The nutrient content of the sunflower oil is retained as much as possible.

The production process of extracting cold-pressed oil from sunflower seeds is as follows:

Pretreatment section

In the pretreatment section, we use magnetic separators, vibrating cleaning sieves, shellers, kernel-shell separating sieves, flaking machines and transfer equipment.

In this stage, we first use magnetic separator and vibrating cleaning sieve to remove impurities such as metal and branches and leaves from sunflower seeds. These impurities are not conducive to oil production on the one hand, and can affect the normal operation of the oil press on the other. After obtaining clean sunflower seeds, we use a sheller and a kernel shell separating sieve to obtain clean sunflower kernels. After that, we will use the flaking machine to press the sunflower seeds into thin slices to improve the oil yield by increasing the contact area between the sunflower seeds and the oil press.

Pressing section

After obtaining clean sunflower seed flakes from the pretreatment section, they are transported to the oil press through the transporter and pressed to obtain sunflower oil.

Filtration section

Finally, the sunflower oil obtained from the press is passed through a filter to remove the fibers and other fine impurities from the oil to obtain clean cold pressed sunflower oil.
