Mechanical Pressing vs. Chemical Extraction: Process Advantages and Suitable Scenarios of Household Sunflower Oil Presses

You've probably found yourself in a situation where you're using a small sunflower seed oil press at home, and no matter how hard you try, the oil yield just isn't what you expect. It's a common headache for many home users. But don't worry; you're not alone, and there are ways to turn things around.

The Core Technical Points Affecting Oil Yield

Let's first break down the key technical factors that influence the oil yield of your home - use sunflower seed oil press.

1. Raw Material Preparation: Drying and Crushing

The dryness and crushing degree of sunflower seeds are crucial. If the seeds are too moist, the oil extraction will be less efficient. According to industry research, sunflower seeds with a moisture content of around 8 - 10% usually achieve better oil yields. As for crushing, a proper level can expose more oil - containing cells, facilitating oil release.

2. Temperature Management during Pressing

Temperature plays a vital role in the oil - pressing process. The ideal temperature range for sunflower seed pressing is between 60 - 80°C. At this temperature, the oil viscosity is reduced, and the oil can flow out more easily. However, if the temperature is too high, it may damage the quality of the oil and the press components.

3. Pressure Curve Setting Logic

The pressure applied during pressing also affects the oil yield. A well - designed pressure curve can gradually squeeze out the oil from the sunflower seeds. Generally, starting with a lower pressure to break the cell structure gently and then gradually increasing the pressure can lead to a higher oil yield.

Three - Step Methodology to Optimize Oil Yield

Here is a practical 'Three - Step Methodology to Optimize Oil Yield':

1. Pre - treatment: Dry the sunflower seeds thoroughly until the moisture content reaches 8 - 10%, and crush them to an appropriate degree.
2. Temperature Control: Set the press temperature to 60 - 80°C before starting the pressing process.
3. Pressure Adjustment: Start with a lower pressure of about 1 - 2 MPa and gradually increase it to 3 - 5 MPa as the pressing progresses.
