As a small or medium-sized sunflower oil factory owner, you may often face the challenges of low oil yield and high costs due to improper equipment combination. In this guide, we'll delve into how to scientifically select the right combination of cold - pressing and hot - pressing equipment to achieve efficient oil extraction, covering the entire process from raw material impurity control to final packaging.

Understand the Core Differences between Cold - Pressing and Hot - Pressing

The first step is to understand the fundamental differences between cold - pressing and hot - pressing processes. Cold - pressing is carried out at a relatively low temperature (usually below 60°C), which can preserve more nutrients in the oil but may result in a lower oil yield. On the other hand, hot - pressing involves higher temperatures (around 100 - 120°C), which can break down the oil cells in sunflower seeds more effectively, leading to a higher oil yield but potentially reducing some nutrient content.

Match Equipment According to Production Capacity

It's crucial to match the equipment according to your factory's production capacity:

Small - scale Factories

For small - scale factories with a daily production capacity of less than 10 tons, a combination of a small cold - press and a filter press can be a good choice. Cold - pressing can ensure the quality of the oil, and the filter press can remove impurities. For example, a small factory in [Location] used to have an oil yield of only 55%. After adopting a small cold - press and a filter press, its oil yield increased to 62%.

Medium - scale Factories

Medium - scale factories with a daily production capacity of 10 - 50 tons can consider a combination of a medium - sized hot - press and a refining system. Hot - pressing can increase the oil yield, and the refining system can improve the quality of the oil. A medium - scale factory in [Location] improved its oil yield from 58% to 65% after upgrading its equipment.

Large - scale Factories

Large - scale factories with a daily production capacity of over 50 tons should opt for a large - scale hot - press combined with a comprehensive refining and packaging system. This combination can achieve high - volume and high - quality production. A large factory in [Location] saw its oil yield soar from 60% to 68% after implementing such a combination.

Key Technical Points in the Whole Process

Controlling raw material impurities is the first step. You should ensure that the moisture content of sunflower seeds is between 8% - 10% for optimal results. Pre - treatment of seeds, such as shelling and cleaning, can also significantly improve the oil yield. During the pressing process, precise control of temperature and pressure is essential. After pressing, proper refining and packaging are necessary to ensure the quality and shelf - life of the oil.

The Importance of Regular Maintenance

Regular maintenance of equipment is vital for long - term stable production. Just like a car needs regular servicing, your oil - pressing equipment also requires routine checks and maintenance. This can prevent breakdowns, ensure the accuracy of process parameters, and ultimately maintain a high oil yield over time.

Conclusion

By scientifically selecting the right combination of cold - pressing and hot - pressing equipment, controlling the whole - process technical points, and performing regular maintenance, you can significantly improve the oil yield of your sunflower oil factory. Whether you're a startup entrepreneur or a traditional workshop owner, these strategies can help you break through the bottleneck and achieve stable profits. Your oil yield may not be ideal now, but with the right approach, you can see a significant improvement.
