Shijiazhuang Xinlu Technology Co., Ltd. – Technical Overview of Sesame Seed Processing Line

Sesame seed processing demands specialized equipment due to the seed's very small size, high oil content, and fragility. The primary goal of a sesame seed processing line is to achieve a high level of purity by removing a wide range of impurities without causing damage or loss of the valuable product. Shijiazhuang Xinlu Technology Co., Ltd. offers processing lines that are meticulously engineered for the gentle and efficient handling of sesame seeds, catering to both the food and oil industries.

The process starts with initial cleaning to remove coarse impurities. A rotary sieve or a vibrating screen with aspiration is typically used. This first step removes large contaminants such as plant stems, pods, and stones. The aspiration system is set to a low velocity to remove dust and light chaff without drawing the good sesame seeds into the waste stream.

The core of the sesame cleaning process often revolves around a double-air screen cleaner specifically configured for small seeds. This machine is highly effective due to its two-stage air separation. The first air channel removes the bulk of the light impurities, and the second provides a final polishing. The screens used have very fine perforations to separate sesame seeds from similarly sized but slightly larger or smaller impurities.

For an even higher purity, especially for the removal of weed seeds and small stones of similar size, a gravity separator is employed. Despite the small size of sesame, modern gravity tables are capable of making separations based on density differences. This helps in removing immature, lightweight sesame seeds and dense mineral particles, resulting in a more uniform and higher-quality product.

In cases where the highest visual quality is required, such as for confectionery use, an optical sorter may be integrated. This machine can identify and eject discolored, damaged, or off-type seeds that have passed through the mechanical cleaning stages, ensuring a product with consistent color and appearance.

For certain applications, a hulling process may be included. This involves gently cracking the husk of the sesame seed and then separating the hulls from the kernels using a combination of aspiration and specific gravity separation. Hulled sesame seeds are lighter in color and are used in specific food products.

The final stage is packaging. Given the small size and value of sesame seeds, precision weighing is crucial. Automated weighing and bagging systems are used to fill small retail packs or larger industrial bags. The entire Sesame Seed Processing Line from Shijiazhuang Xinlu Technology Co., Ltd. is designed with a focus on minimizing seed loss, preventing damage, and maintaining hygiene, often utilizing stainless steel construction and fully enclosed conveying systems to protect the product throughout the process.
