Cold oil press machine, cold press machine for oil extraction
Cold oil press machines have become increasingly popular in recent years due to their ability to retain the nutrients of oil seeds. The process of cold pressing involves pressing oil seeds at temperatures below 60°C, which helps to preserve the nutrients in the oil.
One of the advantages of using a cold oil press machine is that it can improve the quality of the oil while avoiding the generation of harmful materials such as trans-fatty acids or high-quality polymers that can occur during high-temperature processing. Cold pressing also helps to retain the active substances in the oil, making it a healthier option for consumption.
Can provide customers with design and installation of complete sets of 5-500 TPD cold oil press machine.
The double screw cold oil press machine produced by our company is a new and efficient machine that has low power and energy consumption. It can save up to 20% – 30% of electricity when processing the same amount of oil seeds. This machine is suitable for extracting vegetable oil from a variety of seeds such as tea seed, flax seed, cashew nut shell, almond, fire hemp seed, peanut kernels, cottonseed, rapeseed, sunflower, soybean, corn germ, Chinese prickly ash seed, and more.
Advantages of double screw cold oil press machine:
1. Two screw shafts in the same direction in squeezing chamber, transport materials facing oppositely by shearing. With great pushing force, oil route can be cleared by itself.
2. Double screw cold press oil machine, high pressure in squeezing chamber with single pressing, more than 93% of yield efficiency, low residual oil rate in dry cakes.
3. Cold press can completely retain the natural biological active matter in vegetable oils, such as unsaturated fatty acids, vitamins, protease, lecithin and trace elements. Vegetable oil produced by cold oil press machine has nature color and flavor.
4. Strip pressed cake (meal) produced in low temperature is a high value-added food used for animal feed, fertilizer, fuel and protein extraction.
5. Suitable for room temperature pressing and traditional hot pressing process of all kinds of oil seeds.
This oil press machine can be used not only for cold pressing but also for hot pressing, which has a wide range of applications. But generally speaking, this machine is often used for cold pressing.
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.
Cold oil press machines offer a healthier and more efficient alternative to traditional oil extraction methods. They are particularly suitable for extracting vegetable oils from a variety of seeds while retaining the nutrients and active substances in the oil. As the demand for healthier food options continues to increase, cold oil press machines are becoming an increasingly popular choice for consumers and businesses alike.
