Lentils Sesame Processing Plant

Shijiazhuang Xinlu Technology Co., Ltd. - Integrated Processing Solutions for Lentils and Sesame

The processing of lentils and sesame seeds presents distinct technical challenges due to their differing physical characteristics and quality requirements. A specialized processing plant designed for these commodities must incorporate flexible systems that can handle both products, often in campaign operations. Shijiazhuang Xinlu Technology Co., Ltd. designs integrated processing plants that address the specific requirements of both lentils and sesame while maintaining operational efficiency and product quality.

The raw material handling system for these commodities must accommodate significant differences in seed size, shape, and density. Lentils, being larger and more uniform, require cleaning equipment with specific screen configurations and air velocity settings. Sesame seeds, being much smaller, need finer screening surfaces and carefully calibrated aspiration systems to prevent product loss while effectively removing impurities. The plant design typically includes separate intake lines or adjustable cleaning equipment to handle both products effectively.

The cleaning section employs multi-stage screening and aspiration to remove impurities based on size, density, and aerodynamic properties. For lentils, the cleaning process focuses on removing stones, dust, and damaged seeds while potentially grading by size for different market segments. Sesame cleaning requires more precise control to remove microscopic impurities and immature seeds while preserving the valuable oil-rich kernels. Destoners and specific gravity separators may be incorporated to ensure thorough cleaning of both commodities.

Sorting technology represents a critical component in these processing plants. Advanced optical sorters utilizing color cameras, laser technology, or biometric identification systems can detect and remove defective seeds, discolored products, and foreign materials that survive the initial cleaning stages. For lentils, optical sorting focuses on removing stones with similar density and seeds with color defects. For sesame, the technology can identify and remove unhulled seeds, improving the quality of the final product.

For sesame processing, specialized hulling systems may be incorporated. These typically involve soaking the seeds to loosen the hulls, followed by gentle abrasion or brushing to remove the outer layers. The separation of hulls from kernels employs wet or dry methods based on the desired final product specifications. Water floatation systems or specific gravity separators effectively separate the lighter hulls from the denser kernels.

Additional processing modules may include:

• Thermal treatment systems for microbial reduction

• Roasting equipment for flavor development

• Cooling conveyors for temperature stabilization

• Milling systems for producing sesame paste or lentil flour

• Packaging lines for various retail and industrial formats

The plant layout must facilitate easy changeover between processing lentils and sesame, with particular attention to preventing cross-contamination. This includes dedicated storage silos, separate conveying lines where practical, and comprehensive cleaning procedures between product changeovers. The design should incorporate easy-access points for equipment cleaning and maintenance.

Modern lentils and sesame processing plants from Shijiazhuang Xinlu Technology Co., Ltd. incorporate food safety management systems aligned with international standards. The equipment selection emphasizes food-grade materials, particularly stainless steel for product contact surfaces. The facility design includes appropriate zoning to separate raw, processing, and finished product areas, with environmental controls to manage temperature and humidity where necessary.

The scale of these processing plants can range from small operations handling 1-5 tons per hour to larger facilities processing 10-20 tons hourly. The specific configuration depends on market requirements, raw material availability, and product mix. Our engineering approach considers these factors to deliver optimized solutions that balance capital investment with operational efficiency and product quality.
