The cashew nut shelling processing line handles the full workflow of raw in-shell cashews, including grading, cooking, drying, shelling, screening, re-drying, peeling, kernel sorting, roasting, and vacuum packaging.

It delivers a throughput of 100–800 kg per hour, with a maximum kernel peeling rate of 98%. Fully automatic models achieve a shelling rate of 90–95% while keeping the kernel breakage rate within 5–10%.

Replacing labor-intensive manual processing, the cashew nut shelling processing line cuts labor costs and material waste. Suitable for small, medium, and large cashew plants, it produces vacuum-packed cashew kernels ready for export.

Cashew nut production line materials & application scenarios

  • Processed material: Raw in-shell cashews, turned into peeled cashew kernels. Supports roasting, grading, and vacuum packaging.
  • Application scenarios: Small & medium cashew processing plants, agricultural deep-processing factories, export-oriented workshops, and startup projects. Available in semi-automatic for small runs and fully automatic for mass production.
  • Finished products: Graded whole cashew kernels and broken kernels, vacuum-packed and ready for sale.

Core advantages of cashew nut shelling processing line

  • Fully integrated workflow: Covers all steps from raw cashew feeding to vacuum packing. Auto / semi-auto options reduce kernel damage and deliver graded kernels directly.
  • High-quality output: Peeling rate up to 98%, whole kernel rate over 90%. Pre-sorting and precise cutting lower breakage for better export value.
  • Food-grade material: Kernel-contact parts are 304 stainless steel. Corrosion resistant and easy to clean, meeting food inspection requirements.
  • Customizable capacity: 100–800 kg/h throughput. Flexible configuration for small workshops or large-scale production.
  • Labor-saving & simple operation: Only 3–4 workers needed. Adjustable temperature and timing reduce reliance on experienced operators.
  • Extended shelf life: Vacuum packaging prevents oil oxidation and suits long-distance transport and storage.

Complete cashew nut shelling processing line workflow

Raw Material Grading | Cashew Grader

  • Raw in-shell cashews are sorted by diameter using 16/18/20/22/24mm mesh screens.
  • Uniform particle size guarantees stable shelling performance and cuts kernel breakage.
  • Mixed-size raw materials will cause a sharp rise in broken kernels.
  • The number of grading sieves can be customized according to your production needs.
Cashew Sorting Machine
Cashew Steaming Machine

Cooking | Cashew Steaming Machine

  • Sorted cashews are loaded on stacked trays inside the electric steaming tank.
  • It uses thermal expansion and contraction to loosen the connection between shells and seed coats.
  • Adjust steaming duration according to cashew grain size to reduce shelling damage.
  • Steamed cashews need ventilated resting for 2–3 days before entering the shelling step.

Automatic Sheller & Sieve Separator

  • Precision blades cut cashew shells gently without scratching the inner kernels.
  • Vibrating sieve separates shells, whole kernels and fine scraps after shelling.
  • Semi-automatic and fully automatic versions are available for different output plans.

Cashew Kernel Drying Machine

Primary and Secondary Drying | Hot Air Circulation Dryer

  • Shelled cashew kernels are sent in to remove excess internal moisture.
  • Drying temperature and working time can be freely set on the control panel.
  • This pre-processing step prepares kernels for the subsequent peeling operation.
  • Controlled drying makes the brown seed coat crisp to raise the peeling rate.
  • Uneven drying may lead to incomplete peeling or burnt cashew kernels.

Cashew Kernel Peeling Machine

  • Adopts pneumatic physical peeling, no chemicals or additives are used.
  • Automatically separates whole kernels from broken kernels and discharges seed coat waste.
  • A matched air compressor is required to provide stable air pressure.

Cashew Kernel Sorting Machine

Secondary Kernel Grading | Cashew Grader

  • Re-sort peeled kernels into multiple commercial specifications.
  • Graded cashew kernels meet purchasing and export standards and boost product value.

진공 포장 기계

  • Vacuum sealing isolates oxygen and moisture from finished cashew kernels.
  • It inhibits oil oxidation, prevents rancidity and prolongs the storage period.
  • This procedure marks the end of the whole cashew processing line.
Vacuum Packing Machine

Continuous nut roasting machine (optional for this cashew nut shelling processing line): Season and roast cashews on demand to produce roasted kernels.

Selection checklist for cashew nut shelling processing line

Do not choose the cashew line merely by advertised hourly output. Check these key points:

  • Throughput: Confirm hourly in-shell cashew input; separate raw feed and kernel yield (22–24% kernel rate).
  • Automation: Semi-automatic for small batches; fully automatic for export mass production to save labor.
  • Power supply: Verify 380V three-phase power and total load for heating devices.
  • Layout space: Reserve room for machines and material turnover.
  • Quality specs: Confirm limits for breakage and peeling rate; export orders need higher whole-kernel ratio.
  • Extra functions: Check if roasting, color sorting or metal detection is required.

All individual machines on the line must have matched capacity. A low-capacity unit will become a bottleneck and lower the overall production efficiency. Tell us your raw material throughput, export demand, workshop conditions, and automation preferences, and we will provide tailored equipment lists and process solutions.
