How to Improve Oil Yield

Oil yield is crucial in oil production, primarily depending on raw materials, processing techniques, and daily operations.

High-quality oilseeds-those with plump kernels, few impurities, and moderate moisture content-are fundamental. Different oilseeds have different oil contents. A complete pretreatment process, including drying, washing, dehulling, pressing, puffing, crushing, and cooking, can optimize the raw material condition and improve oil yield.

During pressing, proper control of the pressing chamber pressure is essential. The cake thickness and feed rate should be steadily adjusted, and the feed should be even and slow to avoid machine malfunctions. Raw materials require suitable moisture and temperature to maintain good flowability and plasticity. Excessive moisture or temperature will affect normal pressing. In actual production, hot pressing generally yields a higher oil yield than cold pressing.

Furthermore, appropriate pressing time is also important. Extending the pressing time helps increase oil yield, but excessively long pressing times lead to heat loss and reduced efficiency. For oilseeds with high oil content, the pressing time can be appropriately extended. Simultaneously, maintaining a stable pressing chamber temperature is crucial. Excessive temperature will darken the oil color and increase residual oil content, while insufficient temperature will prevent the formation of a suitable oil cake. Generally, the optimal temperature inside the pressing chamber during pressing is 90-110 degrees Celsius. However, beginners often lack an understanding of the machine's internal temperature range, leading to lower-than-expected oil yields. To reduce this, we recommend that novice customers, if their budget allows, purchase MCRAYONE simple temperature-controlled oil press machine. This machine adds an electrical control cabinet to a standard screw press, allowing for temperature control of the pressing cage and improving heating reliability.
