(This diagram represents the typical sequential steps within a comprehensive sesame processing machine line.)

Cleaning & Screening: Raw sesame seeds often contain impurities such as dust, sand, small stones, and foreign organic matter. The initial stage involves a multi-layered vibrating screen or an air separator to remove these impurities. This pre-cleaning step is crucial to protect the downstream equipment and ensure a higher quality end product.
Soaking (Hot Water Immersion): Cleaned sesame seeds are conveyed to a soaking tank. Here, they are immersed in hot water (typically between 70-90°C) for a precise duration, usually 20-40 minutes depending on the variety and condition of the seeds. The hot water causes the hull to swell and loosen, making it easier to separate from the kernel. This process is critical for achieving a high peeling rate with minimal damage. The soaking tank features automated temperature control and circulation systems.
Peeling (Friction-based Hull Removal): After soaking, the softened sesame seeds are transferred to the main sesame peeling machine unit. This unit typically consists of a vertically oriented cylinder with a rapidly rotating agitator or stirring shaft. The principle employed is abrasive friction: the gentle rubbing action between the seeds themselves and between the seeds and the peeling chamber walls effectively removes the loosened hulls without crushing the delicate kernels. The design of the agitator and the chamber's internal surface geometry are crucial to optimize this friction while minimizing breakage. Water is continuously introduced to aid in washing away the hulls.
Hull & Kernel Separation: This is a critical separation stage. Due to differences in specific gravity, the heavier sesame kernels sink while the lighter hulls float in water. The mixture from the peeling unit flows into a separation tank, often referred to as a "flotation separator." Agitation and water flow are precisely controlled to allow the hulled kernels to settle at the bottom and be discharged, while the floating hulls are skimmed off or overflowed with the water, then collected for disposal or further processing (e.g., for animal feed). This continuous separation ensures high purity of the hulled seeds.
Dewatering: The wet hulled sesame kernels, now highly pure, are transferred to a dewatering machine. This typically involves a centrifugal dewaterer or a vibratory dewatering screen. The aim is to remove as much surface water as possible before drying, which significantly reduces the energy consumption of the subsequent drying step.
Drying: The dewatered sesame kernels still contain a significant amount of moisture. They are then conveyed to a dryer, which can be a hot air dryer, a fluidized bed dryer, or a microwave dryer. The drying process carefully reduces the moisture content to a safe level (typically 3-5%) for long-term storage and to prevent microbial growth. The drying temperature and time are precisely controlled to preserve the nutritional value, flavor, and color of the hulled sesame seeds.
Cooling & Packaging: Finally, the dried hulled sesame seeds are cooled to ambient temperature to prevent condensation and maintain quality. They are then ready for packaging into bags, sacks, or bulk container111s, depending on the client's requirements. This final stage often includes an optical sorter to remove any remaining discolored or imperfect seeds, ensuring a premium final product.
