Peanut Seed Processing Line

Peanut Seed Processing Line

Hebei Julite Sorting Technology Co., Ltd. offers its Peanut Seed Processing Line, a turnkey system engineered to convert raw peanuts into clean, graded kernels suitable for roasting, butter making, oil extraction, or further ingredient processing. The line integrates cleaning, shelling, kernel separation, drying, sorting, and packaging stages.

Detailed Processing Sequence

1. Raw Peanut Intake and Cleaning
   Peanuts are fed into a vibrating pre-cleaner that removes stones, soil clumps, and large plant debris. An aspirator then extracts dust and lightweight husk fragments, protecting shelling equipment.

2. Shelling Unit
   The cleaned peanuts enter an impact or abrasive sheller. Adjustable abrasion rings or shelling discs gently crack shells without damaging kernels. A pneumatic separator then divides shells from intact kernels.

3. Kernel Drying and Cooling
   Shelling introduces moisture; a fluid-bed dryer reduces kernel moisture to 2–5% using recirculated warm air. A cooling section restores ambient temperature, stabilizing kernels for grading.

4. Flotation or Density Grading
   Depending on product goals, kernels pass through a water flotation tank that discards hollow or broken pieces, or an air-gravity separator that classifies kernels by density, further improving consistency.

5. Optical Sorting
   A color-sorting module scans kernels under LED lighting. Air jets eject discolored, insect-damaged, or foreign-matter kernels, ensuring a high-quality final product.

6. Metal Detection and Final Packaging
   A metal detector removes any remaining ferrous or non-ferrous particles. Kernels then flow to multi-head weighers and bagging machines that fill bulk or retail packages with precise weight and minimal dust generation.

Machine and Line Features

• Food-Grade Materials: All contact surfaces use 304 stainless steel, with smooth welds and crevice-free design for easy sanitation.

• Control and Monitoring: A PLC/HMI panel displays throughput, shelling rates, moisture levels, and reject counts. Recipe presets store optimal settings for different peanut varieties and end uses.

• Modular Expandability: Processors can start with core cleaning and shelling modules, then add flotation, optical sorting, or packaging equipment as business needs evolve.

• Maintenance Accessibility: Slide-out shelling chambers, tool-free access panels, and centralized lubrication points minimize downtime for cleaning and servicing.

Operational Benefits

• High-Quality Output: Multi-stage cleaning, shelling, and sorting produce consistently clean kernels ready for roasting, butter production, or oil pressing.

• Optimized Yield: Gentle shelling and precise sorting reduce kernel breakage and remove defective pieces, maximizing saleable product.

• Energy Efficiency: Variable-frequency drives and heat-recovery circuits in drying modules reduce energy use while maintaining throughput.

• Versatile Capacity: Lines support throughputs from 1 t/h to 10 t/h, meeting the needs of small processors and large industrial plants alike.

Hebei Julite Sorting Technology Co., Ltd. provides complete project support for each Peanut Seed Processing Line: site evaluation, installation oversight, operator training, and preventive-maintenance services to ensure reliable operation and compliance with safety and quality standards.
