Industrial screw oil press solutions: improving oilseed oil yield and production efficiency

With the growing global demand for high-quality vegetable oils, especially in health-conscious markets such as North America, Europe, and Southeast Asia, efficient, stable, and safe oil extraction capabilities have become a core competitive advantage for oil processing companies and exporters. Leveraging 43 years of industry experience, the QIE Group provides oilseed processing companies with industrial-grade screw presses and end-to-end optimization solutions, helping to increase oil yield by up to 18% while significantly reducing downtime.

Key processes for improving oilseed oil yield

Proper feed pretreatment and temperature control are crucial to efficiency before any oilseeds are fed into a screw press. According to data from the Food and Agriculture Organization of the United Nations (FAO) and the International Council on Vegetable Oils (IOPC), differences in pretreatment of different oilseeds can affect oil yield by 12–15%.

Pretreatment and Processing Recommendations for Different Oilseeds

Case Study : A sunflower oil processing plant in Kazakhstan increased its oil yield from 38% to 42% and reduced its monthly downtime by approximately 12 hours after using our screw press.

Intelligent maintenance avoids common faults

Even the best machines can malfunction if they are not regularly inspected and improperly maintained. Based on field data from multiple of our customers, here are some common problems and solutions:

• ✅ Problem : Low oil yield and poor pressing effect
  Cause : Wear on the screw conveyor blades or misalignment of the discharge screen.
  Solution : Replace the blade every 6 months under heavy use, and calibrate the pressure sensor monthly.

• ✅ Problem : The oil is cloudy or contaminated.
  Cause : Oil accumulation in the pressing chamber and filter lines
  Solution : Regularly clean the pressing chamber and oil filtration lines to ensure compliance with international food safety standards such as HACCP.

Regular cleaning of the pressing chamber and oil filtration lines prevents contamination—a key factor in meeting EU food safety standards (such as HACCP) and winning repeat orders from high-end buyers.

Advantages of industrial-grade screw presses

QIE Group's industrial screw presses are designed with durability, precision, and food safety in mind.

• 1️⃣ Durability : High-strength alloy screw shaft and press body

• 2️⃣ Precision : Intelligent pressure control and temperature monitoring ensure stable oil yield.

• 3️⃣ Efficiency : Output can be increased by up to 18%, and downtime is reduced by approximately 30%.

• 4️⃣ Compliance : Meets HACCP and ISO food safety standards in markets such as the EU and North America.

By combining pretreatment optimization and intelligent maintenance solutions, companies can achieve higher oil yield, lower energy consumption, and less waste.
