Our company’s double-screw cold press machine is an advanced, energy-efficient model that boosts oil yield and product quality while reducing power consumption by 20-30%. It is widely used in small oil mills, medium oil plants, and large-scale cold pressed oil production lines.
What is a Cold Press Machine?
A cold oil press machine (also known as a cold press oil extraction machine) is specialized equipment designed to extract oil from oilseeds at low temperatures (below 60°C). Unlike traditional hot pressing, cold pressing requires no heating or chemical additives, helping preserve the oil’s natural nutrients, aroma, and bioactive compounds.
Wide Application of Cold Oil Press Machines
This machine is suitable for extracting high-quality vegetable oils from various raw materials, including: tea seeds, olives, flaxseeds, peanuts, almonds, rapeseeds, sunflower seeds, cashew shells, hemp seeds, Sichuan pepper seeds, and other oil-rich crops.
This makes it an ideal choice for cold pressed oil plants and specialty oil production facilities, such as olive oil pressing plants, nut oil extraction plants, and organic vegetable oil producers.
Why Choose Cold Pressing?
Today, consumers increasingly prefer cold pressed oils for their rich nutritional content and natural flavor. The cold-pressing process offers multiple advantages:
✔ Preserves Nutrients
Cold pressing retains: unsaturated fatty acids, vitamin E, lecithin, polyphenols, antioxidants, natural enzymes, and bioactive compounds.
✔ Avoids Harmful Byproducts
By eliminating high-temperature processing, it prevents: trans fatty acids, thermal polymers, and oxidation byproducts.
✔ Clean, chemical-free process
Cold pressing requires no: solvents, chemical refining, high-temperature bleaching, or deodorization.
✔ Higher-value oil and oil cake
Cold-pressed oil cake is rich in: protein, dietary fiber, amino acids, and minerals.
This makes it ideal for animal feed, organic fertilizer, fuel, and protein extraction.
Advantages of Our Double-Screw Cold Oil Press Machine
1. Unique double-screw design
Two parallel screws rotate in the same direction while simultaneously conveying material in opposite directions through shear force, ensuring efficient material transport and natural oil separation.
2. High Oil Yield and Low Residual Oil Content
Achieves oil extraction rates exceeding 93% in a single press, significantly reducing residual oil in the cake to maximize the value of oilseeds.
3. 100% Nutrient Retention
Oil retains its natural color, aroma, and bioactive compounds, making it a premium product suitable for food-grade and health supplement markets.
4. Low-Temperature Pressing, High Value-Added
Defatted cake can be utilized for feed, fertilizer, biomass fuel, and protein extraction, increasing by-product revenue.
5. Suitable for Cold and Hot Pressing
Optimized for cold pressing yet compatible with hot pressing, pre-pressing, and combined pressing lines.
6. Energy-Efficient Design
Reduces power consumption by 20-30% compared to traditional oil presses, making it ideal for large-scale oil mills.
Cold press oil extraction method
Cold press is the physical method of oil extraction. Pressure in increased without heating up, thus it has no effect on the substance in oil. In addition to the common characteristics of general oil extraction process, it can also improve the oil quality, avoid the generation of harmful materials like trans-fatty acids or high quality polymer in high temperature processing and retains the active substances in the oil. In the cold press of tea seed oil, cold pressed oil can avoid harmful substances such as acid, alkali and heavy metal in residual oil caused by adding chemical additives in the process of refining and shorten the process. A third of the production cost can be saved, reduces the project cost of investment and enhances the market competitiveness of products. In addition, the nutritional value of protein in tea seed cake is improved after pressing, dietary fiber and other nutrients are not denatured and the active material can be kept that ensures the development and utilization value of cake, which can be used for animal feed, fertilizer, fuel and protein extraction.
When choosing between cold and hot pressing technologies, it is important to consider the intended use of the produced vegetable oil. Cold-pressed oils are generally considered healthier due to their ability to retain nutrients and active substances. Additionally, cold-pressed oils are less likely to contain harmful materials that can be generated during high-temperature processing.
