●Today, we will discuss the practical techniques for cold-pressing and hot-pressing soybean oil. For cold-pressing soybeans, no pre-treatment of the raw materials is required, and the process is relatively straightforward. Typically, pressing the beans twice achieves the desired oil yield. Of course, if you have particularly high requirements—such as pursuing a very high oil extraction […]
●Today, let’s talk about three methods of oil extraction: cold pressing, hot pressing, and medium-temperature pressing, and explain each clearly. Cold pressing is the most straightforward. The oilseed does not undergo preheating treatment and is placed directly into the oil press. Repeating the pressing two to three times usually extracts the oil completely. Hot pressing,
●Current manufacturing technology for oil presses is quite mature. In terms of oil yield, there is no significant difference between round-bar and strip-bar oil presses. However, if a comparison must be made, the strip-bar oil press is simpler to operate, easier to repair, and more convenient to maintain in the long run. Additionally, the press
