Sunflower seed oil extraction

Detailed Introduction to Sunflower Seed Oil Extraction

Sunflower seed oil extraction is a process of extracting edible oil from sunflower seeds through physical or chemical methods.

The process flow of sunflower seed oil extraction

• Raw material preparation: Choose sunflower seeds with high oil content, usually 30% -50%.
• Cleaning and shelling: Use a cleaning machine to remove impurities, and then separate the shell and kernel through a shelling machine.
• Crushing and steaming frying: Crush sunflower seeds and steam fry them to soften the oil and improve oil yield.
• Squeezing: It is carried out using a spiral oil press or a cold press, and is divided into two methods: cold pressing and hot pressing.

Cold pressing: retains more nutrients, suitable for high-end products.

Hot pressing: High oil yield, but slightly lower oil quality.

• Filtration and refining: The pressed crude oil needs to undergo coarse and fine filtration to remove impurities and residues.
• Degumming, deacidification, decolorization, deodorization: further refining through chemical or physical methods to ensure that the finished oil meets national standards.
• Packaging: Fill finished oil products into bottles or barrels for easy sales.

Small sunflower seed oil press

The oil press machine is the heart of an oil pressing operation, but how it look or its structure will determine the ease of operation and the overall oil output rate. There are several types of these machines you will come across, however, we recommend two basic small scale sunflower seed oil press machines: one is conventional screw type, and the other is automatic press with vacuum filter.

Typically, the conventional screw small scale oil press machine is composed of a feeder, a gearbox, pressing cage, a screw shaft, and the extraction stand. All these are combined to realize continuous sunflower seed oil extraction with easier operations. The pressing chamber containing the pressing cage and the screw shaft is the key part of the functioning of this machine. the screw shaft on different modles is set up with various styles of screw, and they rotate when the machine is running to push the sunflower seed materials into the chamber. There the oil is separated out through extrusion of pressing worm as well as the pressing ring.

The Automatic oil press with vacuum filter is an advanced model of the conventional screw type, helping save labor power as well as simplifies the oil processing step. It’s composed of a feeder, a press chamber, the electric control, the heating system inside the press cage, the vacuum filter drum and an oils sight glass that help the user control the speed of oil clearing process. Both of these machines are pretty good when it comes to processing sunflower seed oil, but the conventional one is a little cheaper than the one with vacuum filter. However, the automatic oil press machine will yield better sunflower seed oil and can be set up very quickly.

Equipment selection

Small oil press: suitable for individuals or small businesses, equipped with spiral oil press, oil filter, refining equipment, etc., with low investment cost.
Large scale oil production plants: suitable for large-scale production, equipped with a complete set of pre-treatment, pressing, refining, and packaging equipment, such as the fully automatic production line provided by Fude Machinery.
Equipment advantages: Spiral oil press has a large output, low residual oil, and high production efficiency; The cold pressing process preserves more nutrients.

Advantages of small scale sunflower seed oil press machine

• Lower price and more acceptable: although the price of small sunflower seed making machine will vary from the functional configuration and the machines capacity, they are generally cheaper that large-scale oil press machine hence more acceptable to a majority of customers.
• Fewer requirements for operation: Both large and small oil pressing machines performs all the function necessary for edible oil production. However, small scale sunflower seed oil press machine are more convenient because they require fewer operation conditions like small space of operation.
• Less labor requirement: Most small scale oil pressing machines only requires 2 to 3 person to run the whole line.
• Functional: small-scale oils pressing machines for sunflower seed are capable of handling both hot and cold pressing, other than that, they can also be used to press other types of oil seeds.

If you have a small to medium-sized oil pressing workshop, then the small sunflower seed press produced by Zhengzhou Fude Machinery is your ideal oil pressing equipment. These machines have the characteristics of one-time pressing, low energy consumption, small footprint, and most importantly, require a small amount of investment.
