Comprehensive Overview of Sesame Processing Lines

Sesame seeds have been a staple crop and valuable oilseed for millennia, prized for their rich nutritional profile and versatile culinary applications. A well-designed sesame processing line transforms raw seeds into high-quality hulled seeds, tahini paste, and cold-pressed oil, meeting the diverse needs of food manufacturers and retailers. Shijiazhuang Xinlu Technology Co., Ltd. specializes in providing turnkey sesame processing solutions that integrate robust cleaning, hulling, roasting, pressing, and packaging units into a seamless workflow.

Key Components and Workflow

1. Pre-Cleaning and Grading: Raw sesame seeds contain impurities such as stones, husks, and plant debris. Initial cleaning employs vibratory sieves and destoners to remove coarse contaminants, followed by air-aspiration systems that eliminate lighter particles like chaff. Grading machines sort seeds by size and density, ensuring uniformity for subsequent processes.

2. De-hulling: High-performance de-hullers fracture and separate the fibrous outer coat from the seed kernel, enhancing oil yield and improving color and flavor consistency. Hulling is achieved through abrasion or pneumatic impact, carefully calibrated to minimize kernel damage.

3. Roasting (Optional): For applications requiring a nutty aroma—such as tahini or snack coatings—roasting chambers heat seeds uniformly at controlled temperatures. This step develops flavor compounds without compromising nutritional content.

4. Oil Extraction: Shijiazhuang Xinlu Technology Co., Ltd. offers both mechanical screw presses and hydraulic presses for cold-pressed sesame oil. Precision pressure control and gradual feed rates ensure maximum oil recovery while preserving delicate unsaturated fatty acids.

5. Filtration and Refining: Crude oil passes through a multi-stage filtration system, removing particulate matter and residual moisture. For markets demanding refined oil, optional neutralization, bleaching, and deodorization units are available.

6. By-Product Processing: Pressed sesame cake remains a protein-rich feed or flour ingredient. Grinding and sifting modules convert cake into uniform powder for animal feed or functional food applications.

7. Packaging and Storage: Automated filling machines package seeds, paste, or oil into jars, pouches, or drums. Nitrogen flushing and vacuum sealing extend shelf life, while synchronized palletizing lines streamline logistics.

Quality Control and Automation
Integrated PLC systems monitor temperature, pressure, and throughput rates in real time, allowing operators to adjust parameters remotely. In-line sensors assess oil moisture and color, triggering alerts for deviations. Frequent product sampling and laboratory testing ensure compliance with international food safety standards.

By choosing Shijiazhuang Xinlu Technology Co., Ltd.’s sesame processing line, producers benefit from optimized throughput, consistent product quality, and energy-efficient operations that reduce downtime and maintenance costs. Whether launching a new sesame oil brand or expanding existing capacity, our solutions combine modular flexibility with proven reliability, supporting sustainable growth in today’s competitive market.
