How to extract oil from sunflower seeds?

Processing sunflower seed oil

Sunflower oil is an ingredient naturally derived from sunflower seed. It is also an ingredient used throughout the world to improve the quality of food. Cooking with butter is usually considered bad, but if you use the oil effectively and gradually, your body will be useful. The use of sunflower oil in the preparation of most dishes can be useful for food and even improve them. This article describes how to process cooking oil from sunflower.

If you have ever experienced sandwiching olives between two bowls until they are squeezed into liquid, then this process is the same as the method used in producing sunflower seed oil.

Another term for squeezing sunflower seeds is cold pressing. No chemicals are used to produce sunflower oil, but when cold pressed, no heat is produced. This is a natural way to get sunflower oil that is healthy for human consumption.

Cooking oil from sunflowers also called refined oil because it has not undergone many processes that have become the consistency that we all know. The taste is also more noticeable and more complete. The only disadvantage of getting outdated methods of processing sunflower oil is that it is not roasted properly, because it does not withstand extremely high temperatures.

What equipment is needed to extract sunflower seed oil?

The equipment required for extracting sunflower seed oil mainly includes the following parts, which vary depending on different extraction processes (such as pressing, leaching) and production scales (small or large).

Preprocessing equipment

• Shell huller: used to remove the outer shell of sunflower seeds and improve oil yield.
• Screening machine/cleaning machine: used to screen out impurities and unshelled sunflower seeds.
• Steaming and frying pan: used to heat sunflower seeds, soften cell walls, and increase oil yield.
• Rolling machine: further crushing sunflower seeds to increase the extractability of oil.

Squeezing equipment

• Oil press: It is the core equipment for extracting sunflower seed oil, and can be divided into hydraulic oil press and spiral oil press according to different processes. Hydraulic oil presses have good oil quality but low efficiency, while spiral oil presses have high automation, efficiency, and oil yield, but the oil quality is slightly inferior to cold oil presses.
• Cold press/hot press: According to different temperature controls, it is divided into cold press and hot press. Cold pressing preserves more nutrients, while hot pressing is more efficient.

 refining equipment

• Degumming equipment: such as alkali refining pots and degumming pots, used to remove gum from crude oil.
• Decolorization equipment: such as decolorization pots, activated clay decolorizers, and leaf filters, used to remove pigments and odors.
• Deacidification equipment: such as neutralization pots and deacidification pots, used to remove free fatty acids.
• Deodorization equipment: such as deodorization pots and combined deacidification and deodorization towers, used to remove odors from oils and fats.
• Dewaxing equipment: such as crystallization tanks, dewaxing filter presses, centrifuges, used to remove wax.
• Filtering equipment: such as bag filters, centrifuges, and leaf filters, used to remove impurities.
• Cooling and crystallization equipment: such as cooling towers, crystallization tanks, and crystallization tanks, used for cooling and crystallization treatment of oil products.

The sunflower seed oil refining machine is used to remove impurities from crude oil, including steps such as degumming, deacidification, decolorization, deodorization, and dewaxing, in order to improve the quality and safety of oil products and meet edible standards.

What are the benefits of using an oil press to press sunflower seed oil?

Using an oil press to press sunflower seed oil has the following benefits:

• Preserving Nutrients: The pressing method does not use chemical solvents, maximizing the retention of nutrients such as polyunsaturated fatty acids, proteins, vitamins, and trace elements in sunflower seeds, making it suitable for use in health foods.
• Easy to operate: The pressing process is relatively simple and suitable for small and medium-sized oil factories or family workshops. It is easy to operate and user-friendly.
• High oil yield: Modern oil presses (such as spiral oil presses) are designed with advanced technology, high oil yield, and can adapt to the pressing needs of different oil crops.
• Less equipment investment: Compared to the leaching method, the pressing method requires lower equipment investment and is suitable for small and medium-sized oil plants, with lower equipment maintenance costs.
• Good oil quality: The pressed sunflower seed oil has a clear color, rich aroma, high oil fume point, and is suitable for cooking and consumption.
• Environmental protection and energy conservation: Some oil presses use energy-saving motors and automated control, reducing energy consumption and meeting environmental requirements.
• Widely applicable: not only suitable for sunflower seeds, but also for pressing various oilseeds such as peanuts, soybeans, sesame, etc.
