Comprehensive Overview of Sesame Processing Line

Sesame Processing Line – Comprehensive Overview of Workflow and Technologies

Hebei Julite Sorting Technology Co., Ltd. specializes in developing efficient and reliable grain and seed processing solutions. Among our core product lines is the Sesame Processing Line, a system specifically engineered to handle the unique characteristics of sesame seeds, which are small, lightweight, and rich in oil content. Processing sesame requires careful handling to maintain purity, quality, and oil integrity.

Understanding Sesame Characteristics

Sesame seeds are hygroscopic, delicate, and prone to breakage if not handled with precision. Their high oil content also makes them sticky and difficult to separate using conventional grain cleaning techniques. This complexity demands a tailored processing approach, designed to ensure optimal cleaning, sorting, and packaging, while minimizing contamination and waste.

Typical Workflow of a Sesame Processing Line

A complete sesame processing line is composed of several interconnected stages, each fulfilling a distinct function to ensure that only clean, high-quality sesame reaches the final stage.

1. Pre-cleaning

Pre-cleaning is the first essential step. It removes large impurities such as sticks, stones, leaves, and other foreign materials using vibrating screens and aspiration systems. The purpose of this step is to prevent damage to subsequent machines and to start separating unwanted materials from the raw product.

2. Fine Cleaning

The cleaned sesame then passes through a series of machines designed for precision removal of fine dust, immature seeds, and other small particles. Equipment in this stage may include:

• Gravity separators – to separate heavier and lighter particles.

• Destoners – to eliminate stones that are similar in size to sesame but denser.

• Magnetic separators – to remove any metallic contaminants.

• Air screen cleaners – for final dust and chaff elimination.

Each unit is calibrated for sesame’s unique size and weight distribution to prevent loss or damage.

3. Dehulling (Optional)

For markets that require hulled sesame, a dehulling unit may be included. This process involves softening the outer shell with water or steam and then gently removing it through mechanical rubbing or abrasion. After hulling, the sesame must be dried efficiently to avoid microbial growth.

4. Color Sorting

This is one of the most critical stages. Using optical or CCD color sorters, sesame seeds are scanned in high resolution to detect and reject discolored, defective, or moldy seeds. Sorting accuracy is key to ensuring food safety and aesthetic uniformity in final products.

5. Final Grading and Packaging

Once the seeds are cleaned and sorted, they are graded according to size and density. Grading ensures consistency and market readiness. After grading, sesame is conveyed to packaging stations, where it can be packed into bulk bags or retail-ready pouches.

Technological Innovations in Sesame Processing

Hebei Julite Sorting Technology Co., Ltd. integrates advanced automation and digital control systems into sesame lines to ensure:

• Consistent throughput

• Reduced manpower requirements

• Lower energy consumption

• Real-time monitoring and data tracking

Sensor-based monitoring allows for instant feedback, enabling operators to adjust parameters and reduce downtime. All contact surfaces are made with food-grade stainless steel to maintain hygiene standards.

Key Benefits of a Dedicated Sesame Processing Line

1. Product Purity – Multiple cleaning and sorting stages ensure nearly complete removal of impurities.

2. Minimized Product Loss – Precision equipment minimizes breakage and product rejection.

3. Custom Configuration – Lines can be adjusted based on processing capacity, seed variety, and end-use application.

4. Improved Shelf Life – Removal of contaminants and moisture control contribute to longer product shelf life.

Applications

Processed sesame seeds are used in various industries including food production (tahini, baked goods, oils), pharmaceuticals, and cosmetics. A properly configured processing line enhances the quality and market competitiveness of the final product.

Hebei Julite Sorting Technology Co., Ltd. continues to support sesame producers and exporters by offering durable, low-maintenance, and high-performance processing solutions. Our sesame processing lines are designed for ease of integration into both small-scale and industrial-scale operations, helping clients optimize productivity and quality assurance.
