Working Principle and Advantages of a Sesame Gravity Separator

During the harvesting and processing of sesame, impurities such as stones, dirt, shriveled kernels, immature seeds, and sesame leaf husks often enter the sesame, seriously affecting the quality of the sesame and subsequent processed products. Traditional manual screening methods are not only inefficient but also difficult to accurately distinguish the subtle differences between sesame and impurities, making them unable to meet the demands of large-scale, high-quality processing.

This sesame gravity machine, based on advanced gravity sorting technology, achieves precise separation based on the density differences between sesame and various impurities. During operation, the sesame material forms layers on the gravity table, driven by the combined effects of wind and vibration friction. The heavier, fuller sesame seeds sink, while the lighter, shriveled seeds and impurities float to the top. The continuous vibration of the gravity table moves the high-quality sesame seeds in the lower layer upward, while the impurities in the upper layer flow downward, ultimately being discharged through different outlets, achieving efficient separation.

This gravity machine boasts numerous technological innovations. The gravity table’s wooden frame is crafted from imported, premium wood, offering exceptional impact resistance and durability. The screen surface is constructed from 304 stainless steel, offering excellent wear resistance and strength, significantly extending the equipment’s service life. The fan’s variable frequency speed control allows for precise control of the gravity table’s air volume, making it particularly suitable for processing small sesame seeds and those with frequent varietal changes.

Using this gravity machine not only significantly reduces labor costs but also increases the purity of sesame seeds to over 95%, significantly increasing processing efficiency. Furthermore, precise grading allows for more efficient utilization of sesame seeds of varying qualities, significantly increasing the product’s added value.
